Claim:
1. A device for providing temporary access to the heart through a tissue wall of the heart, the device comprising: an anchor having a ring-shaped body having a central opening and at least one wire spiral having a pointed distal end and having a proximal end that is connected to said body, the at least one wire spiral being shaped for juxtaposition with the exterior surface of the wall of the heart and the at least one wire spiral having a distal tubular region of substantially constant diameter and a frustoconical proximal region that decreases from the distal tubular region, a detachable handle having a base formed with a central aperture and an interconnection means linking said base to said anchor, said handle including an elongated guide section that is formed with an elongated central passageway open at opposite ends, an elongated, hollow needle having a pointed tip for insertion through the wall of the heart so as to enter the heart, the needle being slidably received in said elongated central passageway, and means securing said hollow needle to said guide section for limiting the distance said hollow needle can be axially moved within said guide section while locating said pointed tip so that it penetrates the heart wall before said wire spiral makes contact with the exterior surface of the wall of the heart, whereby, once said needle is caused to penetrate into the heart, the device can be readily attached to the heart wall by screwing the wire spiral into the tissue wall of the heart via rotation relative to an axis coinciding with said needle, so that the device will then provide access to the heart along a guide wire that extends through said anchor, the guide wire being insertable through the lumen of the hollow needle before the hollow needle is withdrawn.
