Abstract
Official abstract text for this publication.
A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vessel filter delivery system, comprising: a) an elongated flexible tube having a central, longitudinal axis, proximal and distal ends, and a tube wall with an outer surface and an inner surface surrounding a tube lumen that extends from the proximal end to the distal end; b) an expandable vessel filter stored within the tube lumen in a compressed state, the filter including a head and multiple legs extending distally of the head, at least some leg…
