Abstract
Adhesive bonded positive fixation epicardial lead including an electrode support member for supporting an electrode and an adhesive which adheres the electrode support member and the accompanying electrode to an exterior wall of the heart. Surgical mesh can also be affixed to the electrode support member so that after decay of the adhesive, tissue ingrowth provides for adherence of the electrode support member to the tissue of the heart wall.
Claims6
An electrode assembly suitable for chronic implantation within the human body comprising:
- an electrode support member of material substantially inert to body fluids;
- an epicardial electrode attached to said electrode support member;
- first means attached to said electrode support member capable of long-term adhesion of said electrode support member to body tissue for affixing said electrode support member to body tissue after a time subsequent to implantation of said electrode assembly without penetrating said body tissue;
- and
- second means attached to said electrode support member capable of epicardial attachment of said electrode support member for affixing said electrode support member to body tissue without penetrating said body tissue from implantation of said electrode assembly until said time subsequent to implantation of said electrode assembly, when said second affixing means loses resiliency.
