Problems solved by technology

However, problems are still common as the device is not anchored in 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

Funnel-trap type delivery and / or retrieval devices for Inferior Vena Cava (IVC) filters or other medical implants are described in which the devices comprise two layers of braid with an axially support member. The support member may be interposed between braid layers or set inside the braid layers but interposed between heatset features. Delivery and / or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated herein.

Description

technical field [0001] Embodiments described herein relate to intravascular temporary inferior vena cava (IVC) filters, other implants, or other foreign object 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, usually through the femoral or internal jugular vein access. Most currently available temporary filters include a hook-shaped member by which the temporary filter can be captured within a catheter or sheath and accommodated for removal by use of a gooseneck snare or a multi-loop snare. [0003] While retraction is in principle a simple procedure, capturing the hook of the filter with the snare loop(s) is often difficult. Such difficulties are compounded when the filter is placed at an angle or out of balance. Various filters are designed to avoid such orientations. However, problems are still common ...
