Abstract
A thrombus filter element for placement within a blood vessel lumen defined by a blood vessel wall is disclosed. A thrombus filter element in accordance with the present invention includes a hub having a proximal end, a distal end, and a lumen extending therethrough, a plurality of wires extending from the hub, at least one end of each wire being fixed to the hub proximate the proximal end thereof, a plurality of struts radiating away from the hub, the fixed end of each strut being fixed to the hub proximate the distal end thereof, and a slider rod slidingly disposed within the lumen of the hub.
Claims22
A thrombus filter element for placement within a blood vessel lumen defined by a blood vessel wall, comprising:
- a hub having a proximal end, a distal end, and a lumen extending therethrough;
- a plurality of wire extending proximally from the hub;
- each wire having a first end and a second end;
- the first end of each wire being fixed to the hub proximate the proximal end thereof;
- the second end of each wire being fixed to a coupling;
- the plurality of wires being mechanically biased to expand radially toward the blood vessel walls and to form a basket;
- a plurality of struts radiating distally away from the hub;
- each strut having a free end and a fixed end;
- the fixed end of each strut being fixed to the hub proximate the distal end thereof;
- the plurality struts being arranged to form an array;
- a slider rod slidingly disposed within the lumen of the hub;
- the slider rod having a distal end and a proximal end;
- and
- the proximal end of the slier rod being fixed to the coupling.
