Patent Images
1. A suturing device comprising:
- a guide body;
a translating mechanism which translates at least one needle relative to the guide body;
a rotatable sleeve disposed over at least a distal portion of the guide body, wherein the rotatable sleeve is operably attached to the guide body such that the rotatable sleeve may rotate about the guide body while substantial axial movement of the rotatable sleeve relative to the guide body is prevented.

11. A suturing device comprising:
-
a guide body; a translating mechanism to translate at least one needle relative to the guide body; a flexible tube having a proximal end connected to the guide body, a distal end, and a guide wire lumen initiating at the distal end and terminating in a guide wire exit port between the proximal end and the distal end; and a sleeve rotatably disposed about the guide body. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A suturing device comprising:
-
a guide body having a proximal end, a distal end, and an internal lumen; a needle guide having a proximal end attached to the distal end of the guide body and a distal end having at least two needle guide channels, said needle guide further including a proximal region and a distal region, wherein the needle guide channels are disposed in the distal region and wherein the proximal region includes a recessed portion for receiving a section of tissue; a pair of needles; a length of suture having two ends, with each end attached to one of the needles and with at least a portion of the remaining length of suture passing through the internal lumen of the guide body; a shaft reciprocatably mounted within the guide body and carrying the needles to reciprocate the needles within the needle guide channels; and a pair of receiving channels in the guide body which are separate from the internal lumen, wherein the pair of needles are operably connected to the shaft such that reciprocation of the shaft draws the needles into the receiving channels and draws the length of suture from the internal lumen. - View Dependent Claims (20)

21. A method for suturing a puncture site in a blood vessel wall disposed at the distal end of a percutaneous tissue tract, said method comprising:
-
introducing a suturing device having a guide body and a flexible tube distally extending from the guide body to the puncture site so that the guide body lies within the tissue tract and the flexible tube lies within the blood vessel lumen; drawing a pair of needles with a length of suture therebetween from the flexible tube through the blood vessel wall adjacent the puncture and outward through the tissue tract, wherein at least a portion of the length of suture extending between the pair of needles passes through a lumen in the guide body and is located outside the patient during the introduction step, wherein the length of suture is pulled back through the guide body lumen during the drawing step, and wherein the needles are received into receiving channels within the guide body which are separate from the lumen; and securing a loop in the suture to close the punctures. - View Dependent Claims (22, 23, 24, 25, 26, 27)
