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 two hollow needles;
a distal member configured to be inserted within a lumen of a vascular vessel, said member having a receptacle, wherein the receptacle is elongate, 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 needle channel and a second opening providing a passageway into the receptacle;
a length of suture material having two needle engaging fittings, each of the two needle engaging fittings being positioned in the receptacle to engage at least one of the at least two hollow needles entering from the second opening, one of the two needle engaging fittings being disposed proximal to the other needle engaging fitting within the receptacle, wherein the two needle engaging fittings in the receptacle have differing cross-sectional diameters and are axially displaced from each other, a distal-most needle engaging fitting being smaller in cross-sectional diameter than a proximal-most needle engaging fitting, the receptacle in said distal member is being substantially in line with the longitudinal axis of said needle channel and the intermediate member deviates from the longitudinal axis.

Abstract
A surgical device for suturing vascular vessels is described, as well as methods for suturing tissue employing the surgical device. The device includes a distal member for insertion into a vascular vessel puncture wound. The distal member contains a suture and needle engaging fitting. At least one 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.

16. 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 hollow needle and including a needle cartridge slidably mounted thereon configured to contain a plurality of hollow needles; a distal member configured to be inserted within a lumen of a vascular vessel, said 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; a length of suture material having two needle engaging fittings, each of the two needle engaging fittings being positioned in the receptacle to engage the at least one hollow needle of the plurality of hollow needles entering from the second opening, a first needle engaging fitting of the two needle engaging fittings being disposed proximal to the other needle engaging fitting within the receptacle, the first needle engaging fitting having a cross-sectional diameter greater than that of the other needle engaging fitting. - View Dependent Claims (17, 18, 19, 20, 21, 22)
