Suturing device and method for sealing an opening in a blood vessel or other biological structure

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.

主权项

1. A suturing device, comprising:
a handle; an elongated body coupled to a distal end of the handle; a shaft slidingly disposed within the handle and the elongated body, wherein an expandable suture capture component is mounted on a distal portion of the shaft, the expandable suture capture component being operable to alternate between a deployed configuration in which the expandable suture capture component radially expands and extends away from the elongated body and a compressed configuration in which the expandable suture capture component is disposed within the elongated body, at least one pair of needles moveable to a deployed position in which the at least one pair of needles distally extend from the distal end of the elongated body and into the expandable suture capture component with the expandable suture capture component in its deployed configuration and a retracted position in which the at least one pair of needles is disposed within the elongated body, each needle including a distal end configured to penetrate through a vessel wall.
