简要总结

The purpose of this registry study is to gather real world standard of care (SOC) data on the safety and performance on the Roxwood Medical catheter devices in the treatment of stenotic lesions and CTO.

详细描述

The Roxwood Anchoring Catheters are a group of artery catheters used in participants undergoing interventional procedures. These anchoring catheters are support catheters used in conjunction with guidewires to access discrete regions of the coronary and peripheral vasculature. They may be used to facilitate placement and exchange of guidewires and/or other interventional devices beyond stenotic lesions, including CTOs. The goal of this registry study is to collect prospective observational data on the performance of the Roxwood CenterCross™, CenterCross™ Ultra, CenterCross™ Ultra LV, MultiCross™, and MicroCross™ 14, 14ES and 18 MicroCatheter devices through 24 hours and the safety of the devices through 30 days in native coronary and peripheral arteries with a stenotic lesion or CTO. Additionally, the catheters will be evaluated for the ability to facilitate a guidewire successfully penetrating the proximal cap of the stenotic lesion or CTO and the infusion of saline and contrast agents as confirmed by angiography.

Of the 100 intended participants to be treated, it is anticipated that at least 50 participants will be enrolled and treated using the Roxwood MicroCross™ 14, 14ES and/or 18 MicroCatheter and 50 participants will be enrolled and treated using the CenterCross™, CenterCross™ Ultra, CenterCross™ Ultra LV, and/or MultiCross™ devices.

Adverse Events will be coded according to Medical Dictionary for Regulatory Activities (MedDRA). Data from the study will be collected via electronic data capture (EDC). Clinical data will be extracted in the desired format by the BTG Data Management from the EDC on an ongoing basis to support data review activities. An independent monitor will visit the investigational site and review the Electronic Case Report Forms (eCRFs). Data entered in the EDC will be immediately saved to a central database and changes tracked to provide an audit trail.

研究组 & 干预措施

Roxwood Anchoring Catheters

Participants will be treated for an index procedure using Roxwood Medical device(s) as prescribed by the Investigator SOC on Day 0. All devices will be used in accordance with the Instructions for Use (IFU). Participants are to be administered SOC acetylsalicylic acid (ASA) and/or anti-platelet medications orally per physician discretion prior to the index procedure. Administration of an intravenous injection of heparin during the index procedure will also be at the discretion of the Investigator per Institutional SOC.

结局指标

主要结局

Number of Participants Without an Index Procedure Related Safety Incident Related to the Roxwood Medical Device

时间窗: Index Procedure (Day 0) to 24 hours Post Procedure

An index procedure safety incident related to the Roxwood Medical Device is defined as a distal embolization, major perforation or dissection in need of emergent surgical intervention as confirmed by angiography, and bleeding (change from baseline hemoglobin \>3 grams/deciliter \[g/dL\]).

Number of Participants with a Successful Index Procedure by Roxwood Medical Device(s)
