    • A suture device and method according to the present invention involves positioning a body (12) of the suture device inside a sheath (11) and extending the body through a vessel wall (14). The sheath, in one embodiment, is a sheath through which a medical procedure has been performed and which has remained positioned within an opening in the vessel. First (24) and second (22) cannulae, in the form of sharpened needles, are inserted through the vessel wall and through adjacent subcutaneous tissue on opposite sides of the vessel wall opening. A snare or loop (34) is carried by the first needle on a first side of the vessel opening. A suture (50) is carried by the second needle on a second side of the vessel opening. The snare is deployed inside the vessel so that it assumes an opened, pre-oriented, three-dimensional configuration. The suture is then extended into the vessel and positioned inside of the open area formed by the snare or loop. In one embodiment, the snare includes a V-shaped configuration such that as the snare is pulled back into the first needle, the snare closes around and grasps the free end of the suture to hold it securely against the opening in the first needle. After the suture is properly positioned across the vessel opening, the first and second needles are withdrawn away from the vessel wall along with the suture device, and the suture is tied or clamped to approximate tissue surrounding the opening in the vessel.
    • 根据本发明的缝合装置和方法包括将缝线装置的主体(12)定位在护套(11)内并且使身体延伸穿过血管壁(14)。 在一个实施例中,护套是护套,通过该护套已经执行了医疗程序,并且其保持位于容器的开口内。 第一(24)和第二(22)插管以锋利针的形式插入穿过血管壁并穿过血管壁开口相对两侧的相邻皮下组织。 一个圈套(34)由第一针承载在容器开口的第一侧上。 缝合线(50)由第二针承载在容器开口的第二侧上。 该圈套被部署在容器内部,以便它采取打开的,预定向的三维构型。 然后将缝合线延伸到容器中并定位在由圈套或环形成的开放区域的内部。 在一个实施例中,圈套包括V形构造,使得当圈套被拉回到第一针中时,圈套围绕并且抓住缝合线的自由端以将其牢固地保持抵靠第一针中的开口。 在缝合线穿过血管开口正确定位之后,第一针和第二针与缝合装置一起从血管壁撤回,并且将缝合线捆扎或夹紧以接近容器中开口周围的组织。
