ABSTRACT:
A medical device of improved design includes an elongated member for insertion into the body, a flexible tension member extending along the elongated member to an attachment upon which tension is desired to be applied, and locking means associated with the elongated member at a point outside of the body to secure said flexible member under tension. The locking means consists of a pair of locking members disposed in close association with each other at a predetermined point along the proximal portion of said flexible tension member, one locking member being movable relative to the other locking member in motion laterally across the path of the tension member under tension to a locking position in which the tension member is bent and secured between cooperating locking members. Preferably, one locking member is rotatable relative to the other. The flexible tension member may extend within a fluid-carrying conduit defined by the elongated member, which in preferred embodiments is in the form of a catheter.
