Medical snaring device

摘要

A snaring device (82) for use with a percutaneous cannula positioned in a body wall and extending into a body cavity of a patient. The snaring device has an elongated, bendable member (84) formed from a spring material and having a first bendable member end and a second bendable member end. The snaring device also has an elongated, control member having a first control member end and a second control member end. The snaring device further has an attachment flexibly connecting the first control member end and the first bendable member end, such that the attachment is insertable through the cannula while the control member is extended alongside the bendable member. A distal portion of the bendable member is configurable into a loop by simultaneously pushing on the second bendable member end and pulling on the second control member end while the distal portion is at least partially extended into the body cavity.
