    摘要: Devices and methods for closing an arteriotomy include a percutaneously placeable central tube deployable about the arteriotomy by which an array of radially expandable fingers having suction ports can be engaged with the surface of tissue about the arteriotomy enabling the fingers to grip the tissue without piercing it. A delivery tube can advance a closure element along the outside surface of the central tube, thereby radially contracting the fingers and puckering the gripped tissue to approximate the edges of the arteriotomy. The closure element is further advanced until it is forced off of the distal tips of the fingers such that the closure element surrounds the puckered tissue and secures permanent closure of the arteriotomy.

    摘要: An implant for closing an arteriotomy includes a head having a proximal surface and a distal surface. A tapered plug extends from the distal surface of the head. A plurality of prongs also extends from the distal surface of the head. Upon implantation, the distal surface of the head faces an outside surface of the vessel wall, the tapered plug is disposed within the passage, and the prongs are disposed in tissue of the vessel wall surrounding the passage. The prongs may include a barb to assist in embedding the prongs in the tissue surrounding the puncture. The implant may be bioabsorbable.
