Retrieval apparatus and methods for use
First Claim
1. An apparatus for retrieving material within a body lumen, the apparatus comprising:
- a core wire extending from a proximal end to a distal tip;
an actuator member defining a lumen configured to receive at least a portion of the core wire, the actuator member being proximal to the distal tip of the core wire; and
a distal basket having a distal enclosed end fixed relative to the core wire and one or more elements extending from a proximal open end to a collar slidable on the core wire,the collar being slidable on the core wire within an interior of the distal basket such that, when the collar contacts the actuator member, the collar applies an inward force to direct the proximal open end of the distal basket radially inwardly.

Abstract
An apparatus and method for capturing material within a body lumen are disclosed. The apparatus includes a core wire extending from a proximal end to a distal tip, an actuator member defining a lumen for receiving at least a portion of the core wire, and a distal basket having a distal enclosed end fixed relative to the core wire and one or more elements extending from a proximal open end to a collar slidable on the core wire. The collar is slidable on the core wire within an interior of the distal basket such that, when the collar contacts the actuator member, the collar applies an inward force to direct the proximal open end of the distal basket radially inwardly.

15. A method for removing a material within a body lumen, the method comprising:
-
introducing a basket device into the body lumen in a contracted condition, the basket device comprising; a core wire extending from a proximal end to a distal tip; an actuator member defining a lumen configured to receive at least a portion of the core wire, the actuator member being proximal to the distal tip of the core wire; a distal basket having a distal enclosed end fixed relative to the core wire and one or more elements extending from a proximal open end to a collar slidable on the core wire; and a proximal basket comprising a distal open end and a proximal enclosed end fixed to the actuator member; deploying the distal basket such that the distal basket expands within the body lumen and the proximal open end is disposed distal to the material to be removed; deploying the proximal basket such that the proximal basket expands within the body lumen and the distal open end is disposed proximal to the material to be removed; directing at least one of the proximal and distal baskets towards the other to capture the material through the open ends into interiors of the proximal and distal baskets; advancing the actuator member distally until the actuator member contacts and pushes the collar distally to apply an inward force to direct the proximal open end of the distal basket radially inwardly; and removing the basket device capturing the material from the body lumen. - View Dependent Claims (16)
