Problems solved by technology

However, this problem is still common because the device is not anchored into the IVC in a stable manner
In addition to blood clots, continued blood flow can disorient the filter within the IVC, making recapture difficult

Abstract

A funnel catcher-type device made of shape-set (eg, heat-set) braid for delivery and / or retrieval of inferior vena cava (IVC) filters or other medical devices is described. Delivery and / or retrieval devices, kits including them, methods of use, and methods of manufacture are contemplated. Additional shape forming tools, methods, and apparatus embodiments are also described herein.

Description

technical field [0001] Embodiments described herein relate to intravascular (percutaneous delivery) inferior vena cava (IVC) filters or other implants, retrieval devices or systems and methods. Background technique [0002] Temporary IVC filters are placed much like permanent filters, but are designed so that they can be retrieved in a separate endovascular procedure, typically from the femoral or internal jugular vein access. Most currently available temporary filters include hooked features that can be used to capture and receive them within a catheter or sheath to allow them to be removed by using a gooseneck snare or a multi-loop snare. snare) to remove. [0003] Although recovery is in principle a simple process, difficulties are often encountered when utilizing the loops of the snare to catch the hooks of the filter. This difficulty is exacerbated when the filter is tilted or placed improperly. Several filters are designed to avoid such orientation. However, this p...
