Intended Use

The Bipore Balloon Dilation Catheter is intended to be used for percutaneous transluminal angioplasty of the iliac, femoral and renal arteries, and for percutaneous transluminal angioplasty of the autologous or synthetic arteriovenous dialysis fistulae.

Device Story

Bipore Balloon Dilation Catheter is an over-the-wire, double-lumen catheter for percutaneous transluminal angioplasty (PTA). Input: guidewire (up to 0.035") inserted through one lumen to navigate to stenosis site. Operation: inflation/deflation of distal non-compliant nylon 11 balloon via second lumen; balloon exerts controlled radial pressure to dilate vessels or fistulae. Radiopaque markers at balloon ends provide visual reference for positioning. Used in clinical settings by physicians. Output: mechanical dilation of target vessel/fistula. Benefit: improved burst resistance due to nylon 11 material compared to previous PET design; enables higher rated burst pressures for various balloon sizes.

Clinical Evidence

Bench testing only. Testing included burst pressure (yield), fatigue (40 cycles), compliance (diameter expansion at 4-15 atm), inflation/deflation time (<60s), tensile strength (>5 lbs), stent expansion simulation, and 3-year accelerated shelf-life aging. All tests performed at 37°C on radiation-sterilized units. Results demonstrated compliance with specifications at 95% confidence/99.9% reliability.

Technological Characteristics

5 French nylon-based double-lumen shaft; non-compliant Nylon 11 balloon; radiopaque markers; Teflon protective sleeve. Sterilization: radiation (min 40 kGy). Connectivity: none. Dimensions: 3mm-12mm balloon diameters. Energy: manual hydraulic inflation. Materials: Nylon 11 (Besvo A).

Indications for Use

Indicated for percutaneous transluminal angioplasty (PTA) of iliac, femoral, and renal arteries, and autologous or synthetic arteriovenous dialysis fistulae. Prescription use only.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

Bipore, Inc. Balloon Dilation Catheter K961980

#### Device Description:

The Bipore Inc. Balloon Dilation Catheter is an over-the-wire double lumen balloon catheter designed for percutaneous transluminal angioplasty (PTA) in peripheral arteries, including iliac, femoral, and renal arteries. The catheter consists of a 5 French nylon-based shaft with two lumens. One lumen is for inflation and deflation of the balloon. The other lumen accepts a guidewire for manipulation of the catheter to the site stenosis. Guidewires up to 0.035" diameter may be used. There is a bifurcated proximal juncture that provides access to each lumen.

A non-compliant dilation balloon of nylon (11) is at the distal end of the catheter. When inflated, the balloon exerts a controlled radial pressure.

{1}------------------------------------------------

Located under the proximal and distal ends of the balloon are radiopaque markers, which provide a reference point for locating the balloon within the vessel.

A Teflon™ sleeve is placed over the deflated balloon prior to shipping. This sleeve is designed to protect the balloon in storage and is removed prior to use.

# Information on proposed change to the device:

The currently cleared device uses a polyethylene terephthalate (PET) balloon. The rated pressure for 3mm through 8mm balloons is 12 atmospheres. (Atm.) The rated pressure for the 10mm balloon is 10 atmospheres. (Atm.) And, the rated pressure for the 12mm balloon is 8 atmospheres. (Atm.) The change from PET to Nylon balloon construction material improves the burst resistance of the device. Because of the improved properties of the Nylon polymer rated burst pressures increase to 15 atmospheres for 3mm through 8mm balloons, 12 atmospheres for the 10mm balloon and 10 atmospheres for the 12mm balloon size.

The material is nylon 11 manufactured by ELF Atochem designated Besvo A. This material is known to be commonly used in the manufacture of similar type medical devices.

All materials and assembly processes except for the balloon are identical to the original 510(k) submission. Newly performed FMEA identified seven items that were evaluated to access the suitability of material change to nylon.

- 1. Balloon pressure to yield (burst test).
- 2. Balloon multiple inflations (to access the element of fatigue)
- 3. Balloon compliance (ability of the balloon to expand to a predetermined diameter at a specified pressure).
- 4. Balloon inflation and deflation time.
- 5. Tensile strength at the catheter shaft connection.
- 6. Balloon pressure to burst when placed within stent (expansion)
- 7. Shelf life at simulated three-year period.
