Intended Use
The Vanguard IEP Peripheral Balloon Angioplasty System with Integrated Embolic Protection is indicated for percutaneous transluminal angioplasty (PTA) and capture and removal of embolic material during angioplasty, for the femoral, iliac, popliteal and profunda arteries. The System is not intended for use in the renal, cerebral, coronary or carotid vasculature.
Device Description
The Vanguard IEP Peripheral Balloon Angioplasty System with Integrated Embolic Protection platform is similar to a catheter with a typical angioplasty balloon, but between the distal end of the balloon and the distal tip of the catheter, there is a nitinol-based filter. The device is over-the-wire (OTW) and is 0.018" guidewire compatible. The balloon catheter comes in sizes of 5 and 6 mms outside diameter (OD) and lengths 40, 80, 120 and 200 mms. The filter component is composed of a nitinol filter frame with an overlying membrane perforated with a set pattern of drilled holes. The balloon catheter shaft consists of a dual lumen inner shaft placed inside a single lumen outer shaft. The inner shaft extends beyond the balloon up to the distal catheter tip. Radiopaque markers placed on either side of the balloon and the distal tip of the filter assist with accurate placement. The nitinol filter frame has radiopaque markers, making the diameter of the filter visible when opened. The proximal end of the nitinol frame slides freely over the distal shaft. A pull-wire attaches the handle to the filter frame to activate the filter.
More Information

No
The device description and performance studies focus on the mechanical aspects of the balloon angioplasty system and embolic filter, with no mention of AI or ML.

Yes
The device is a peripheral balloon angioplasty system used for percutaneous transluminal angioplasty (PTA) and embolic material capture/removal, which is a therapeutic medical intervention.

No

The device is described as an angioplasty system with integrated embolic protection, used for percutaneous transluminal angioplasty (PTA) to treat blockages and capture embolic material. This is a therapeutic intervention, not a diagnostic one.

No

The device description clearly outlines a physical catheter system with a balloon, filter, guidewire compatibility, radiopaque markers, and a pull-wire mechanism, indicating it is a hardware-based medical device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • Device Function: The Vanguard IEP Peripheral Balloon Angioplasty System is a device used within the body (in vivo) to perform a medical procedure (angioplasty and embolic protection) on blood vessels. It does not analyze samples taken from the body.

The description clearly outlines a device used for a therapeutic intervention within the circulatory system, not for diagnostic testing of biological samples.

No

A PCCP authorized device would explicitly state its authorization under the Predetermined Change Control Plan within the clearance letter, often in sections related to the device's authorization or the scope of the clearance. The provided text does not contain any mention or indication that this device is authorized as a PCCP device.

Intended Use / Indications for Use

The ability to capture iniected thrombus and successfully retrieve the thrombus was demonstrated. Acute and 28-day histological analysis showed no local injury in the treated arteries and optimal local toleration. There was no evidence of embolization in the dependent tissues from either the Day 0 or Day 28 animal.

Clinical Study A prospective, multicenter study to evaluate acute safety and clinical performance of the nine centers in Belgium and Germany. The conduct of this study is in compliance with ISO Study 14155:2011, Good Clinical Practices (GCP) and the Declaration of Helsinki.

The study enrolled and treated 113 subjects, of which 112 were available for 30-day followup. All subjects presented with evidence of peripheral vascular disease. Mean age was 67.4 ± 10.3 years. The study population was predominantly male (63.7 %). Among the major risk factors, 28.3% of subjects had diabetes, 54% had hyperlipidemia, and 70.8% were hypertensive. 71.7% were either past or current smokers.

The vessels treated included superficial femoral arteries (75.2%), external iliac arteries (9.7%), common iliac arteries (8.9%), popliteal arteries (4.4%) and common femoral arteries (1.8%)

All enrolled subjects were successfully treated with the study device.

Both primary endpoints, assessing safety (Freedom from MAE, defined as death, amputation and target vessel revascularization at 30 days post-procedure) as well as effectiveness (Procedural Success is defined as
