JETi Hong Kong Post Market Study (PMS)

Completed

• Conditions: Peripheral Venous Thrombosis; Peripheral Arterial Thrombosis; Peripheral Arteriovenous Thrombosis
• Interventions: Device: JETi Hydrodynamic Thrombectomy System

• Registration Number: NCT06340763
• Lead Sponsor: Abbott Medical Devices

Brief Summary

The JETi Hong Kong PMS is a single-arm, multicenter study to collect real-world data on the safety, performance, and clinical benefits of the JETi System for the treatment of acute and subacute thrombosis in the peripheral vasculature. This is a post-market study that will register approximately 20 subjects at approximately 5 centers in Hong Kong. Subjects participating in this study will be followed for up to 30 days (in cases of prospective consent) after Day 0. Day 0 is defined as the day when the JETi catheter is introduced into the intended vasculature of the subject.

Detailed Description

The JETi System is a hydro-mechanical aspiration system manufactured by Abbott Medical, consisting of a catheter, pump set, and accessories. The system is intended to remove/aspirate fluid and break-up soft emboli and thrombus from the peripheral vasculature and to subselectively infuse/deliver diagnostics or therapeutics with or without vessel occlusion.

This study will collect data on how the JETi System performs in the treatment of patients undergoing a percutaneous thrombectomy procedure for peripheral thrombosis. Subjects treated for arterial, venous, or arteriovenous thromboses, and subject with diagnoses such as acute limb ischemia (ALI), chronic limb ischemia/chronic limb threatening ischemia (CLI/CTLI), peripheral artery disease (PAD), deep vein thrombosis (DVT), hemodialysis access thrombosis, and others may be included.

Both prospective and retrospective consent (if all assessments needed for the primary endpoints are complete) are permitted. After index procedure, subjects will be evaluated at discharge and 30 days in cases of prospective consent. In cases of retrospective consent, duration of participation will vary. If consent occurs after the procedure and prior to 30 days, the subject will be asked to return for a 30-day visit. If consent occurs after 30 days, the subject will not need to return for a study visit. Relevant data will be collected from the medical record.

Primary Outcome Measures

Name	Time	Method
For Arterial and Arteriovenous Subjects: Composite of JETi-related major adverse events (MAEs)	Up to 30 days post-index procedure	JETi-related major adverse events (MAEs), defined as the following JETi-related events adjudicated by a clinical events committee (CEC) (subject basis): death, major amputation of the treated limb, or major bleeding.
For Venous Subjects: Percent of treated vessel(s) with ≥ 75% venous thrombus reduction via modified Marder score (limb basis).	During the procedure	Percent of treated vessel(s) with ≥ 75% venous thrombus reduction from pre-JETi venogram to final venogram (post-JETi AND after any/all adjunctive therapies to treat underlying culprit lesions) via modified Marder score (limb basis). The modified Marder score is a scoring system used for quantitative assessment of deep vein thrombosis on the basis of their venographic appearance. The modified Marder score ranges from 0 to 24, with 0 representing no thrombus and 24 representing complete thrombosis. The independent imaging core laboratory will be responsible for assessing this endpoint.
For Venous Subjects: Composite of JETi-related major adverse events (MAEs)	Up to 30 days post-index procedure	JETi-related major adverse events (MAEs), defined as the following JETi-related events adjudicated by a clinical events committee (CEC): death, symptomatic pulmonary embolism (PE), major bleeding, or re-thrombosis of JETi-treated vessel(s).
For Arterial and Arteriovenous Subjects: Clot removal grade for each JETi-treated vessel	During the procedure	Clot removal grade for each JETi-treated target vessel from pre-JETi angiogram to post-JETi angiogram (post-JETi thrombectomy and prior to any adjunctive therapies to treat underlying culprit lesions) per the grades (vessel basis). The independent imaging core laboratory will be responsible for assessing this endpoint.; The rate of clot removal grade for each JETi-treated target vessel will be measured as per the Grades below: Grade I: \< 50% reduction; Grade II: 50- \<95% reduction; Grade III: 95-100% reduction.
