A device for sealing a hole in an anatomical structure comprises an elongated member formed with a proximal portion extending along a first axis and a distal portion extending along a second axis, wherein the second axis is different from the first axis and wherein a needle retention channel extends within the distal portion to a distal opening formed in the proximal end of the distal portion. A central portion connects the proximal and distal portions. In use, the device is guided into the hole in the anatomical wall and positioned in a first orientation so that the distal opening faces a first desired location on the inner wall. Thereafter, a first needle is withdrawn from the needle retention channel by drawing proximally a suture coupled to the first needle so that the first needle passes through the first desired location out of the body. The elongated member is then rotated within the hole to a second orientation so that the distal opening faces a second desired location on the inner wall. The second needle is then withdrawn from the first needle retention channel by drawing a second portion of the suture proximally so that the second needle passes through the second desired location out of the body and the ends of the length of are tied together to seal the hole.

[ What is claimed is:] [1.] A device for sealing a hole in an anatomical structure within a living body comprising:an elongated member including a proximal portion extending along a first axis and a distal portion extending along a second axis, wherein the second axis is different from the first axis and wherein a needle retention channel extends within the distal portion to a distal portion opening formed in the proximal end of the distal portion and a central portion, wherein a proximal end of the central portion is coupled to a distal end of the proximal portion and a distal end of the central portion is coupled to a proximal end of the distal portion;first and second needles which, in a first configuration, are received within the needle retention channel, wherein in a second configuration, the first needle is drawn proximally out of the needle retention channel so that the entire length of the first needle is outside the elongated member while the second needle remains within the needle retention channel, and in a third configuration, the second needle is drawn proximally out of the needle retention channel so that the entire length of the second needle is outside the elongated member; anda loop of suture a first end of which is coupled to a distal end of the first needle and a second end of which is coupled to a distal end of the second needle, wherein, in the first configuration, the loop of suture extends through at least a portion of the needle retention channel to extend to a proximal end of the elongated member.
