The Inperia Advance Post-Market Retrospective Study

Inperia Advance Carbostent™ for Infra-popliteal Artery Stenosis. Evaluation of Safety and Performance in Everyday Clinical Practice: The Inperia Advance Post-Market Retrospective Study

The Inperia Advance Carbostent™ is a CE-marked infra-popliteal stent for treatment of infra-popliteal artery stenosis. The aim of this post-market retrospective study protocl P32203 is to collect clinical data of patients treated with Inperia Advance for the treatment of infra-popliteal artery stenosis in routine clinical practice. In order to obtain long-term follow-up data, the data collection will be limited to patients that have been treated with the device at least 12 months prior to the study start.

Study Overview

• Status: Not yet recruiting
• Conditions: Peripheral Arterial Disease
• Intervention / Treatment: Device: Inperia Advance

Detailed Description

The objective of this post-market study is to systematically collect retrospective clinical data on the implantable medical device Inperia Advance in the daily clinical practice in an unselected population treated within the intended use. Data will be collected via medical chart review in anonymous form to assess the safety and efficacy of Inperia Adavance. The Inperia Advance Carbostent™ is a CE-marked infra-popliteal stent for treatment of infra-popliteal artery stenosis.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of Major Adverse Events (MAE)	Composite endpoint of all causes of death, unplanned target limb major amputation and/or clinically indicated target lesion revascularization (TLR)	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Primary patency	Primary patency is defined as absence of clinically-driven target lesion revascularization or binary restenosis. Binary restenosis is defined as a peak systolic velocity ratio (PSVR) >2.4 (Duplex Ultrasound evaluation)	6 months and 12 months
Limb-salvage rate (LSR)	Limb-salvage rate (LSR) is defined as rate of patients free from major amputation. Major amputation is defined as at or above ankle, as opposed to minor amputation being at or below metatarsus preserving functionality of foot	6 months and 12 months
Secondary patency	Patency following successful target lesion revascularization (TLR)	6 months and 12 months or latest patency data available
Death	Death within 30 days of the index procedure	30 days
Clinically driven Target Lesion Revascularization	Clinically driven Target Lesion Revascularization	6 months and 12 months
Target limb ischemia	Target limb ischemia requiring surgical intervention or surgical repair of target vessel rate	6 months and 12 months
Rutherford category measurement	Rutherford category measurement	pretreatment, 6 months and 12 months
Evaluation of Serious Adverse Events (SAEs)	Evaluation of Serious Adverse Events (SAEs)	6 months and 12 months
Acute success (device and procedural) within discharge	Clinical device success defined as successful delivery and deployment of the stent(s) at the intended target lesion (this includes successful delivery and deployment of multiple stents) and final residual stenosis of the target lesion minor or equal to 30%, assessed by visual estimation and clinical device success without the occurrence of MAE during the hospital stay	24/72 hours
