The INT Medical Inflation Device II is the second generation of the manufacturer's balloon inflation range. Three references are supplied. AI25 and AI25A carry analogue gauges, rated for no leakage under 30 and 40 atmospheres. INT-IDE-233 carries a digital gauge and is rated to 30 atmospheres. All three hold 20 mL.

Inflation speed is the headline change. The handle drives a threaded plunger, and the thread pitch is 1.5 times that of the previous generation. INT states this makes inflation 50% faster. In practice, the manufacturer describes reaching 30 atmospheres in as few as three rotations of the handle. The handle is shaped to keep the required force low as pressure climbs. Deflation uses a quick-release mechanism, so pressure can be dropped without unwinding the thread. INT describes this as a push-to-unlock structure, and states it releases easily even from high pressure.

A 30 cm high-pressure extension tube links the device to the balloon catheter. It ends in a male rotating luer. That lets the connection be tightened without turning the tube, which helps the seal hold through an inflation. A 3-way stopcock rated to 500 psi is included. It switches between the balloon line, the contrast source, and a closed position. Gauge choice separates the references. An analogue dial needs no power. The digital option displays pressure as a number on a lit screen. INT specifies customised high-pressure sensors on that reference, with pressure resolved to 0.1 atmospheres.

Medigear.uk supplies all three references to UK catheter laboratories and will confirm sterilisation, shelf life, and UK conformity before order.

Balloon angioplasty is the primary use. A dilatation balloon is advanced to a narrowed vessel and inflated to open it. This device supplies and holds that pressure. Getting the pressure right matters. Too little leaves the lesion under-dilated. Too much risks the vessel wall or the balloon itself. Each balloon carries a rated burst pressure, and the operator works below it while reaching the pressure the lesion needs.

Inflation speed carries clinical weight in this setting. While a coronary balloon is inflated, flow through that vessel is interrupted, and patients may experience chest pain or ischaemic changes. Reaching target pressure in fewer handle turns shortens that window. The quick-release deflation works the same way at the other end of the inflation. This is the practical argument for the second-generation mechanism over a conventional threaded plunger.

Balloon-expandable stent deployment uses the same equipment. The stent sits on a balloon and is expanded against the vessel wall. Post-dilatation to improve apposition often calls for higher pressure, which is where the 40 atmosphere AI25A reference fits. Drug-coated balloon procedures add a timing requirement, since the balloon is held inflated for a defined period, and the digital reference carries a timer for this. Peripheral interventional radiology uses the same device class outside the coronary tree. Contrast handling runs through the 3-way stopcock during a case. An operator switches between drawing contrast, purging air, and closing off the balloon line. Trapped air in the inflation system is a genuine hazard, which is why purging is done with care.

These are single-use devices and must not be reprocessed. Medigear.uk supplies the instructions for use with every order.

Faster Inflation Through a Coarser Thread Pitch

A pitch 1.5 times the previous generation moves more fluid per turn, which INT rates as 50% faster inflation and 30 atmospheres in about three rotations.

Shorter Balloon Inflation Windows

Fewer handle turns to target pressure means less time with coronary flow interrupted, which matters to a patient experiencing ischaemic symptoms during dilatation.

Quick-Release Deflation

A push-to-unlock mechanism drops pressure without unwinding the thread, and INT states it releases easily even from high pressure.

Low Handle Force at High Pressure

The handle is shaped so the effort required stays manageable as pressure climbs, which is where inflation devices are hardest to operate.

Analogue and Digital Gauge Options

A laboratory can keep a familiar dial or move to a lit numeric screen without changing device platform or supplier.

Digital Reference Adds Timing and Fine Resolution

INT specifies 0.1 atmosphere accuracy and a self-starting timer on the digital reference, which suits drug-coated balloon work with a defined inflation period.

Male Rotating Luer on the High-Pressure Line

The connection tightens without twisting the 30 cm tube, helping the seal hold pressure through an inflation.

Consolidated Supply Through Medigear.uk

Medigear.uk quotes all three references on one account, alongside the first-generation range, so a laboratory can order across both families together.

20 mL Syringe Volume

All three references share a 20 mL working volume.

AI25, No Leakage Under 30 atm

The standard analogue reference, despite the 25 in the product code.

AI25A, No Leakage Under 40 atm

The higher-rated analogue reference for procedures calling for greater pressure.

INT-IDE-233 Digital Gauge Reference

A lit digital screen replaces the dial, rated for no leakage under 30 atmospheres.

Screw-Driven Handle With 1.5x Pitch

The threaded drive delivers more volume per rotation than the preceding generation.

Push-to-Unlock Quick Release

Pressure is dropped directly rather than by reversing the handle through its full travel.

30 cm High-Pressure Extension Tubing

Rated tubing links the device to the catheter and holds pressure through inflation.

Male Rotating Luer Connector

The line terminates in a rotating luer so connections tighten without the tube turning.

Three-Way Stopcock Rated to 500 psi

The supplied stopcock switches between balloon line, contrast source, and closed position.

Self-Starting Timer on the Digital Reference

Inflation time is tracked automatically, supporting procedures with a defined dwell period.

Oversized Pressure and Time Digits

The digital display uses large characters intended to stay readable from several angles.

Single-Use Device Classification

Classified under GMDN term 17541 as a single-use catheter balloon inflator, not intended for reprocessing.

The INT Medical Inflation Device II is the faster-cycling member of INT's inflation range, reaching 30 atmospheres in roughly three handle rotations and releasing pressure through a push-to-unlock mechanism rather than reverse winding. Across AI25, AI25A and INT-IDE-233, it covers 30 and 40 atmosphere ratings with a choice of analogue dial or lit digital screen carrying a timer. Medigear.uk supplies all three references to UK cardiac catheter laboratories and interventional radiology suites, quoting single boxes or standing volumes alongside the first-generation range. Before supply, Medigear.uk will confirm sterilisation method, shelf life, box quantity, packing dimensions in LBH mm, the stopcock rating against the AI25A, and UK conformity status.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

It inflates and deflates a dilatation balloon during interventional procedures. It also holds the balloon at a chosen pressure while the operator reads the gauge. Typical use covers coronary and peripheral angioplasty, and balloon-expandable stent deployment. Medigear.uk supplies the range to UK cardiac catheter laboratories and interventional radiology suites.

Both families hold 20 mL and share the 30 cm tubing, rotating luer, and 500 psi stopcock. The difference is the drive mechanism. Device II uses a faster thread pitch and a quick-release handle, which INT rates at 50% quicker inflation. Medigear.uk can quote both families together so a laboratory can compare handling before standardising.

No, and this is worth noting when ordering. AI25 is rated to 30 atmospheres and AI25A to 40 atmospheres. The number in the code does not correspond to the pressure, unlike the AI30 and AI40 references in the first-generation range where it does. Medigear.uk recommends ordering against the written pressure rating rather than the code alone.

INT attributes the gain to a thread pitch 1.5 times that of the previous generation. Each turn of the handle therefore moves more fluid. The manufacturer describes reaching 30 atmospheres in as few as three rotations. Less time spent winding means less time with a balloon inflated. Medigear.uk can request the comparative test data if a service wants it evidenced.

It replaces the analogue dial with a lit digital screen showing pressure as a number. INT's literature for this reference describes pressure accuracy of 0.1 atmospheres, a self-starting timer, one-button operation, and oversized pressure and time digits. The timer suits drug-coated balloon work, where inflation is held for a set period. Medigear.uk will confirm which functions the supplied revision carries.

This needs confirming before the AI25A is standardised. The stopcock is stated at up to 500 psi, roughly 34 atmospheres. The AI25A device is rated to 40 atmospheres, around 588 psi. The stated stopcock rating therefore sits below the device rating. Medigear.uk will obtain written clarification from INT Medical.

It falls under GMDN term 17541, covering single-use catheter balloon inflators, so it is not intended for reprocessing. The sterilisation method, shelf life, and box quantity are not stated in the material supplied. Devices of this class are commonly sterilised with ethylene oxide. Medigear.uk will confirm the actual method and packaging format rather than assume.

The material supplied carries no CE or UKCA marking information. The manufacturing entity is Shanghai Kindly Medical Instruments Co., Ltd., which holds FDA clearance on other references in its inflation range. That does not establish UK conformity. CE status under Regulation (EU) 2017/745, UKCA status, and the UK Responsible Person all need confirming, and Medigear.uk will do so before supply.
