摘要:
A suturing device includes a handle, an elongated body, at least one suture snag, at least one pair of needles, and at least one suture pair. The suture snag is moveable between a deployed position in which two distal arm portions thereof radially extend away from the elongated body and a retracted position in which the two distal arm portions are disposed within the elongated body. The suture pair is slidingly disposed through the needle pair. The suturing device deploys the suture snag within a vessel adjacent to an arteriotomy, extends the needle pair through a vessel wall around the arteriotomy and through the deployed suture snag, extends the suture pair beyond the distal ends of the needle pair, and then utilizes the suture snag to capture the extended suture pair by retracting the suture snag to pull first or distal ends of the sutures back into the suturing device. An inflatable balloon or an expandable suture capture component may be alternatives to the suture snag for capturing the suture ends.
