Abstract

1437354 Cardiovascular leads MEDTRONIC INC 6 June 1973 [9 June 1972] 26999/73 Heading A5R An intra vascular lead 10 comprises an electrode 16 fixed to conductor 12 and being adapted to be firmly lodged in and permanently secured to the body tissue at the required body location, a material inert to body fluids covering at least the conductor 12. The electrode is formed with a sharply pointed tissuepiercing portion and a barb 18 providing the anchorage for embedding in the body tissue e.g. the heart wall. The lead is positioned in the body by means of a device (30) comprising inner and outer tubes 34, 32 of pliant material, the inner tube 34 being fixed to the end of a plunger 42 through which lead 10 extends. Device (30) has a first locking mechanism 49 comprising a slide 50 having a pin 52 engageable in openings in plunger 42 and a sleeve 38 fixed to tube 32. A second locking mechanism 54 comprises a slide 56 having lip which can be grasped to engage and disengage an edge 60 of slide 56 with a groove 66 in plunger 42. With the mechanisms 49, 54 in their locked positions electrode 16 is located within outer tube 32 and a sleeve 22 or conductor 12 abuts the distal end of inner tube 34. Tube 32 is then inserted e.g, into the jugular vein and extended into the heart. Mechanism 49 is unlocked and plunger 42 depressed until the edge of groove 66 is stopped by edge 60 of slide 56 in which position barb 18 extends just beyond end 48 of tube 32 permitting determination of the electrode position with respect to heart tissue. Mechanism 54 is then unlocked and plunger 42 further depressed until shoulders 67 on plunger 42 engage slide 56 thereby driving barb 18 a predetermined distance into the heart tissue.
