Percutaneous catheter and guidewire having filter and medical device deployment capabilities
First Claim
1. A distal protection device, comprising;
- a filtering portion operable between a filtering state and a compact state;
an elongate element having a proximal end, a distal end and a longitudinal outer surface, the distal end attached to the filtering portion;
a mandrel operably connected to a distal end of the filtering portion and at least partially disposed within the outer surface of the elongate element, and a controller portion moving the filtering portion between the filtering state and the compact state, wherein the filtering portion comprises a plurality of struts having a mesh disposed thereon, the struts having a proximal end, a distal end, and a distal region, the distal region of the struts being attached to the mesh and the struts extending proximally from the mesh to attach to the distal end of the elongate element, wherein each strut further comprises a notch between the proximal and distal ends located such that the strut bends outward when longitudinally compressed.

Abstract
The invention provides a nested tubing cannula which comprises outer and inner elongate tubular members, both having a proximal end, a distal end, and a lumen therebetween. The inner tubular member is sealed at its distal end and is nested substantially coaxially within the lumen of the outer tubular member, so that the gap between the inner and the outer tubular member defines a second lumen whereas the first lumen is the lumen of the inner tubular member. A tubular sleeve is disposed coaxially between the inner and outer tubular members. A balloon is mounted on a distal region of the outer tubular member and is in communication with the first lumen. The cannula further comprises a port proximal or distal the balloon occluder and is in communication with the second lumen. Methods for making the devices herein are disclosed.
