1. A method of removing material from a patient'"'"'s breast, said method comprising:
- forwardly inserting a shaft having an expandable biaxially braided member into the breast toward targeted material to be removed, the braided member having a longitudinal axis, a channel, a proximal end, an intermediate region, and terminating in an open, radially expandable distal end which selectively moves between a radially compressed state as a result of the application of longitudinal tension to the braided member and a radially expanded state as a result of the application of longitudinal compression to the braided member;
applying longitudinal compression to said expandable braided member where the distal end radially expands to the radially expanded state as a result of the application of longitudinal compression;
pushing forward said expandable braided member such that at least a portion of the targeted material enters the channel of the expandable braided member through the open distal end;
entrapping said targeted material within said braided member by applying longitudinal tension to the braided member moving said distal end to its radially compressed state; and
using at least one extraneous energy source other than the pushing forward of the expandable braided member to aid said expandable braided member in removal of said targeted material.

Abstract
Medical devices that have a novel mechanical trap(s) on the distal end of a shaft that is used for the removal of material from the body. Further an expandable channel is included to entrap the material that aid with removal or obliteration of tissue or foreign bodies is disclosed.
