Problems solved by technology

However, the problem still prevails because the device is not anchored into the IVC in a stable manner
Constant blood flow other than blood clots can disorient the filter within the IVC, making it difficult to recapture

Abstract

Funnel-trap type delivery and / or retrieval devices for Inferior Vena Cava (IVC) filters or other medical implants are described with associated sheaths. The sheaths are used in progressive recapture and / or embolic protection methods or in association with such features.

Description

technical field [0001] Embodiments described herein relate to intravascular temporary inferior vena cava (IVC) filter or other implant retrieval devices or systems and methods. Background technique [0002] The temporary IVC filter is placed very similar to the permanent filter, but is designed so that it can be retrieved in a separate endovascular procedure, essentially via the femoral or internal jugular vein approach. Most currently available temporary filters include hooked features that can be used to capture and receive them within a catheter or sheath for removal by employing a gooseneck snare or a multi-loop snare . [0003] Although in principle recovery is a simple procedure, it is often faced with the difficulty of catching the filter's hook with the snare loop(s). Such difficulties are compounded when the filter is skewed or unbalanced in placement. Several filters are designed to avoid such orientation. However, the problem still prevails because the device ...
