Abstract
Devices and methods for delivery or retrieval of a distal protection device. A distal protection assembly may comprise an outer sheath, an inner shaft disposed within a lumen of the outer sheath, a distal protection device disposed at a distal end of the inner shaft; and a manifold coupled to a proximal end of the outer sheath that is adapted for moving the outer sheath relative to the inner shaft.
Claims14
A distal protection assembly, comprising:
- an outer sheath having a proximal end, a distal end, and a lumen extending therethrough;
- an inner shaft disposed within the lumen, the inner shaft having a proximal end and a distal end;
- a distal protection device disposed at the distal end of the inner shaft;
- a manifold coupled to the proximal end of the inner shaft, the manifold including an actuator assembly;
- and
- the actuator assembly coupled to the proximal end of the outer sheath and capable of moving the outer sheath relative to the inner shaft, the actuator assembly includes a first button and a second button;
- wherein the actuator assembly is configured such that pressing the first button moves the outer sheath relative to the inner shaft in a first direction and pressing the second button moves the outer sheath relative to the inner shaft in a second direction opposite to the first direction.

A method of actuating a distal protection assembly, comprising the steps of:
- providing a distal protection assembly including an outer sheath having a proximal end, a distal end, and a lumen extending therethrough;
- an inner shaft disposed within the lumen, the inner shaft having a proximal end and a distal end;
- a distal protection device disposed at the distal end of the inner shaft;
- a manifold coupled to the proximal end of the inner shaft, a proximal tubular member including teeth, the proximal tubular member disposed within at least a portion of the manifold and coupled to the proximal end of the outer sheath;
- the manifold including an actuator assembly;
- and the actuator assembly coupled to the proximal tubular member and capable of moving the outer sheath relative to the inner shaft, the actuator assembly including includes a first button and a second button;
- wherein the actuator assembly is configured such that pressing the first button moves the outer sheath relative to the inner shaft in a first direction and pressing the second button moves the outer sheath relative to the inner shaft in a second direction opposite to the first direction.
- actuating the actuator assembly by pressing one of the first button and the second button;
- and
- wherein actuating the actuator assembly shifts the distal protection device between a delivery position and a retrieval position.
