FILTER AND WIRE WITH DISTAL ISOLATION
First Claim
Patent Images
1. A filter assembly, comprising:
- a filter wire having a proximal portion and a distal portion;
a tubular element having a proximal end and a distal end, said tubular element including a compliant portion between its distal and proximal ends and being rotatably disposed about the distal portion of the filter wire; and
a filter secured to the tubular element and located substantially between the proximal and distal ends thereof;
wherein axial movement of the filter wire is at least partially absorbed by the compliant portion of the tubular element.

Abstract
A wire may be configured to provide distal isolation from proximal movement, and a filter may be deployed at or near a distal portion of the wire. A filter may be deployed on a spinner tube that is rotatably disposed about a distal portion of the wire. Axial movement of the filter wire may be at least partially absorbed by the spinner tube. A telescoping wire may include a solid proximal wire section, a solid distal wire section and a joining section that is disposed between the solid proximal wire section and the solid distal wire section. The joining section may translate rotational movement between the distal and proximal sections.

14. A telescoping wire, comprising:
-
a solid proximal wire section; a solid distal wire section; and a joining section disposed between the proximal wire section and the distal wire section, the joining section including a distal region and a proximal region; wherein the joining section is configured to transmit rotational movement between the proximal wire section and the distal wire section yet permit the distal section to move axially relative to the proximal section. - View Dependent Claims (15, 16, 17, 18, 19, 20)
