Attachment of Tubing in a Cardiac Lead

A cardiac lead comprising:

• a thermoplastic tubing;
• a termination element selected from the group consisting of an electrode and a pin connector;
• a thermoplastic fixation element disposed on an exterior of said termination element;
• and
• said thermoplastic tubing having an end portion coaxially surrounding a portion of said thermoplastic fixation element, with a section of said end portion of said tubing being thermoplastically fused to said fixation element, to fix said tubing to said termination element.

A method for fixing a thermoplastic tubing to a termination element selected from the group consisting of an electrode and a pin connector, said method comprising the steps of:

• providing a thermoplastic fixation element disposed an exterior of said termination element;
• positioning an end portion of said thermoplastic tubing coaxially around a portion of said thermoplastic fixation element;
• heating at least a section of and at least a section of said end portion of said tubing to thermoplastically fuse said section to said fixation element;
• and
• allowing said fused sections to solidify to fix said tubing to said termination element.
