A medical device flexible conduit (100) includes an elongated Nitinol strip (102) with a distal end (104), a proximal end (106), a longitudinal axis (108) running from the distal end to the proximal end, a sharp head (110) extending from the distal end, and a channel (112) etched therein. Moreover, the channel is dispositioned along the longitudinal axis. The medical device flexible conduit also includes a flexible tube (114) at least partially jacketing the elongated Nitinol strip between the distal end and the proximal end with the channel and the flexible tube defining a conduit. A method for manufacturing a medical device flexible conduit includes etching a channel into an elongated Nitinol strip and forming a sharp head on a distal end of the elongated Nitinol strip. The method also includes subsequently jacketing the flat elongated Nitinol strip with a flexible tube such that the flexible tube and channel define a conduit. |
