Abstract

A compound barb medical device includes a body portion and at least one barb extending therefrom. The at least one barb defines an inner surface. The inner surface includes a first portion disposed at a first orientation relative to a longitudinal axis of the body portion and a second portion disposed at a second orientation relative to the longitudinal axis. The at least one barb is made from a shape memory material which can be deformed into a temporary shape from a permanent shape. The barb projects from the body portion in a first position relative to the body portion when in the permanent shape and in a second position when in the temporary shape.
