简要总结
To study the early safety and performance of the Shockwave Medical System in subjects to demonstrate that the device can safely and effectively deliver localized energy for the treatment of vascular disease.
详细描述
Shockwave Medical, Inc. intends to conduct a prospective, single-arm, single-center, First in Human study designed to evaluate the early safety and feasibility of the Shockwave Lithoplasty System in subjects with heavily calcified infrainguinal arteries with 3.75mm to 6mm reference vessel diameter at target site. The Shockwave Lithoplasty System is indicated to generate sonic shockwave energy within the target treatment site and disrupt calcium within the lesion to allow for subsequent dilation of a peripheral artery stenosis using low balloon pressure. Up to 10 subjects will be enrolled to undergo lihtoplasty.

- •Female subjects of childbearing potential have a negative pregnancy test less than 7 days before the procedure.
- •Patient is able and willing to comply with all assessments in the study.

排除标准
- •Patients with peripheral arterial disease of Rutherford Category
- •Severe or infected gangrene of the lower extremity.
- •Planned major amputation.
- •Previously implanted stent at the treatment site.
- •Patient with an externally-connected intracardiac catheter or pacemaker.
- •Patient with an implantable pacemaker or defibrillator.
- •Patient has connective tissue disease (e.g., Marfan's syndrome).
- •Patient has a hypercoagulable disorder.
- •Patient has allergy to imaging contrast media for which they cannot be premedicated.
- •Patient is in acute renal failure or chronic renal insufficiency or failure as measured by a serum creatinine of >19.5 µmol/L.
- •Patient has active systemic infection.
- •Patient has less than a one year life expectancy.
- •Patient is pregnant or nursing.
- •Patient is participating in another research study involving an investigational agent that has not reached the primary endpoint.
- •Patient has other medical, social or psychological problems that, in the opinion of the investigator, preclude them from receiving this treatment, and the procedures and evaluations pre- and post-treatment.
- •Chronic total occlusion of target vessel.

- •Highly tortuous arteries (bends greater than 30 degrees over the arc length of the balloon)
- •Patients requiring concurrent intervention below the most distal target lesion.

结局指标
主要结局
Safety determined by 30day New-Onset Serious Adverse Events
时间窗: 30 day
New Onset Serious Adverse Events (SAE) include death, device-related surgery or repeat hospitalization, occlusion, or major unplanned amputation through 30 days following the procedure.
次要结局
- Angiographic Success as measured by residual stenosis <30% reference vessel.(Peri-Procedural)
