Abstract

A medical retrieval device includes a basket formed of two or more loops. The basket may be used to retrieve material (e.g., a urinary stone) from a body. The basket opens and closes for end-encapsulation of a stone and is strengthened by support members that interconnect the basket loops. A captured stone may be from the basket with the basket still in the body by opening the loops.

Claims

1. A method for making a retrieval assembly comprising the steps of:

(a) forming a frame substantially in a plane, the frame comprising at least three loop members, and at least three joining members connecting the loop members to define an aperture of said frame;

(b) folding the frame to superimpose the joining members on one another causing the loop members to form loops extending away from the joining members; and

(c) securing together the superimposed joining members of the frame thereby making the retrieval assembly.
