Vascular suturing device
First Claim
1. A suturing device for suturing an opening in a vascular vessel, said device comprising:
- a proximal member including an elongate body having a needle channel therethrough sized to receive at least one needle and including a needle cartridge slidably mounted thereon configured to contain a plurality of needles, the needle cartridge being biased to automatically and successively align each of the plurality of needles with the needle channel;
a distal member configured to be inserted within a lumen of a vascular vessel, said distal member having a receptacle located therein;
an intermediate member disposed between the proximal member and the distal member, said intermediate member defining a tissue receiving area and having a first opening providing a passageway to the channel and a second opening providing a passageway into the receptacle, the intermediate member including a foot pivotally mounted on a lateral outer surface of the intermediate member and pivotal about pivot axis that extends through the foot and the lateral outer surface; and
a length of suture material comprising a needle engaging fitting positioned in the receptacle to engage a needle entering from the second opening.

Abstract
A surgical device of suturing vascular vessels is described, as well as methods for suturing tissue employing the surgical device. In one form the device includes a distal member that contains a suture and needle engaging fitting. A needle is advanced through tissue adjacent the puncture wound and into the needle engaging fitting to draw lengths of suture material which can then be used to close the puncture wound. In another form the device includes a needle advanceable through tissue and into a needle capture element within a distal end of the surgical device to draw lengths of suture material which can then be used to close various puncture wounds. In still another form the device includes at least one needle advanceable to draw lengths of suture material to close various puncture wounds. A foot is pivotal between a non-deployed and a deployed position.

10. A method of suturing an opening in a vascular vessel, said method comprising:
-
inserting a vascular suturing device through the opening in the vascular vessel, said suturing device comprising a proximal member having a needle channel and a needle therein; a distal member configured to be inserted into a lumen of the vascular vessel, the distal member having a cavity therein and a length of suture material disposed in the cavity, the length of suture having a fitting disposed on each end thereof, the fittings being positioned side by side within the cavity; and a connecting member between the proximal and distal members, the connecting member being crooked to offset the channel and the cavity from the opening in the vascular vessel and having a first opening into the needle channel and a second opening into the cavity; and a foot pivotally mounted on a lateral outer surface of the connecting member and pivotal about pivot axis that extends through the foot and the lateral outer surface; advancing the needle through the needle channel, sufficient to pierce a portion of tissue adjacent the opening in the vessel and extend into the cavity of the distal member; capturing the suture within the cavity with the needle; and retracting the needle carrying a first portion of the suture back through the tissue and the channel. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of suturing vascular tissue adjacent an opening in a vascular vessel, said method comprising:
-
inserting a suturing device through the opening in the vascular vessel, said suturing device comprising a proximal member having a needle channel and a needle therein, said needle carrying a length of suture material; a distal member configured to be inserted into a lumen of the vascular vessel, the distal member having a receptacle comprising a needle capture element and sized to receive at least one needle therein; an intermediate member disposed between the proximal member and the distal member, the intermediate member defining a tissue receiving area and configured to provide a linear needle pathway between the channel and the receptacle; and a foot pivotally mounted on a lateral outer surface of the intermediate member and pivotal about pivot axis that extends through the foot and the lateral outer surface; advancing the needle distally along the needle channel to pierce the vascular tissue and draw a portion of the length of suture material through the vascular tissue; and engaging the needle with the needle capture element in the receptacle. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of suturing an opening in a vascular vessel, said method comprising:
-
inserting a suturing device through the opening in the vascular vessel, said suturing device comprising a proximal member having a needle channel therein; a distal member configured to be inserted into a lumen of the vascular vessel, the distal member having a receptacle therein sized to receive at least one needle therein; an intermediate member disposed between the proximal and distal members, the intermediate member having a first opening providing a passageway to the needle channel and a second opening providing a second passageway into the receptacle and wherein the intermediate member is crooked to offset the needle channel and the receptacle from the opening in the vascular vessel; and a foot pivotally mounted on a lateral outer surface of the intermediate member and pivotal about pivot axis that extends through the foot and the lateral outer surface; deploying the foot to contact vascular tissue adjacent the opening; and advancing a first needle carrying a first length of suture material through the needle channel to pierce a portion of vascular tissue at a first suture site adjacent the opening in the vascular vessel and into the receptacle in the distal member. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
