INT Medical PTCA Semi Compliant Balloon Catheter

Balloon angioplasty opens a narrowed coronary artery by inflating a balloon inside it. In current practice, this is usually preparation rather than definitive treatment. The lesion is dilated so a stent can be delivered and expanded fully against the vessel wall, because a stent forced into an unprepared lesion may not expand evenly. Plain balloon angioplasty without a stent still has a place in small vessels and in-stent disease.

Balloon sizing is the central decision, and it rests on two numbers the operator must have. Nominal pressure is the pressure at which the balloon reaches its labelled diameter. Rated burst pressure is the point beyond which it must not be inflated, and it is calculated statistically from mean burst pressure and its standard deviation rather than being chosen as a round figure. Between those two pressures, a semi-compliant balloon grows, and the compliance chart states by how much at each step. Sizing the balloon to the reference vessel therefore means reading a chart, not reading the label alone.

The consequences of getting it wrong run both ways. An undersized or underinflated balloon leaves the lesion inadequately prepared. An oversized balloon, or one taken past its rated pressure, risks dissection, perforation, or rupture, which is why inflation is done through a device with a pressure gauge rather than by feel. Diameter selection follows the vessel, from 1.25 mm for very small or tightly narrowed segments up to 5.00 mm for large proximal arteries.

Length follows the lesion, with longer balloons treating a diseased segment in one inflation. Medigear.uk supplies the instructions for use with every order.

Unusually Wide Diameter Range

Twelve diameters from 1.25 to 5.00 mm cover very small vessels through to large proximal segments, which few single ranges span.

Quarter-Millimetre Steps Through the Working Range

Sizes at 2.25, 2.75 and 3.25 mm sit where vessel sizing is most sensitive, so a balloon can be matched more closely than half-millimetre steps allow.

Six Balloon Lengths to 40 mm

Lengths from 10 to 40 mm let a long diseased segment be treated in one inflation rather than in overlapping passes.

Tri-Fold Wrap for a Slim Crossing Profile

Folding the balloon into three lobes packs it more tightly around the shaft than a simple wrap, allowing entry into tighter lesions.

Ultra-Low Distal Tip Profile

A fine tip leads the assembly into the lesion, and tip profile is often the limiting factor when a balloon will not cross.

Hydrophilic Coating

A slippery surface lowers the force needed to advance the catheter, which matters through tortuous anatomy and inside a guiding catheter.

Seventy-One References From One Family

The full matrix comes from a single supplier so that a laboratory can stock its entire balloon requirement on one account.

Consolidated Supply Through Medigear.uk

Medigear.uk quotes the balloon range alongside INT's inflation devices, guidewires, microcatheters and guiding catheters on one account.

Semi-Compliant Balloon Construction

The balloon grows in a controlled way as inflation pressure rises above the nominal pressure.

1.25 mm Smallest Diameter

The smallest size in the range, for very small vessels and tight channels.

5.00 mm Largest Diameter

The largest size, for proximal segments and large calibre vessels.

Quarter-Millimetre Sizes

2.25, 2.75 and 3.25 mm sit between the half-millimetre steps.

10 mm and 15 mm Balloon Lengths

Short lengths for focal lesions.

20 mm and 25 mm Balloon Lengths

Mid-range lengths covering most single-lesion work.

30 mm and 40 mm Balloon Lengths

Longer lengths for diffuse disease treated in one inflation.

Tri-Fold Balloon Design

Three folds reduce the wrapped profile around the shaft.

Ultra-Low Distal Tip

The tip is profiled to lead the catheter into challenging lesions.

Hydrophilic Surface Coating

Coating is applied to reduce pushing force during advancement.

Structured Reference Coding

Diameter and length are both encoded in each S-prefixed reference.

Seventy-One Reference Matrix

Twelve diameters by six lengths, less the 1.25 mm at 40 mm combination.

The INT Medical Semi-Compliant Balloon Catheter covers coronary lesion preparation across 71 references, spanning 12 diameters from 1.25 to 5.00 mm and 6 lengths to 40 mm, including quarter-millimetre steps where sizing matters most. A tri-fold wrap and ultra-low distal tip address crossing profile, and a hydrophilic coating reduces pushing force. One matter must be resolved before clinical use. The sheet gives neither nominal pressure, rated burst pressure nor a compliance chart, and a balloon cannot be sized or safely inflated without them. Medigear.uk supplies the range to UK cardiac catheter laboratories alongside INT's inflation devices and guidewires, and will obtain the full pressure data, working length, guidewire and guide compatibility, balloon material, marker configuration, sterility, shelf life, box quantity, packing dimensions in LBH mm, and UK conformity status before supply.
