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

摘要

A suturing device including an elongated body, a distal tip, at least two support arms, and at least two extendable and retractable needles. The distal tip is moveable between an extended position in which the distal tip distally extends from a distal end of the elongated body and a retracted position in which the distal tip is disposed within the elongated body. The support arms are pivotally coupled to the distal tip. When the distal tip is in the extended position, each support arm is in a collapsed position disposed within the elongated body, and when the distal tip is in the retracted position, each support arm is in a deployed position extending radially away from the elongated body. Each needle includes a distal end configured to penetrate through a vessel wall and capture a suture releasably held within a portion of a support arm.

1. A suturing device, comprising:
an elongated body; a distal tip that is moveable between an extended position in which the distal tip distally extends from a distal end of the elongated body and a retracted position in which the distal tip is disposed within the elongated body; at least two support arms pivotally coupled to the distal tip to be actuated by longitudinal movement of the distal tip, wherein each support arm is in a collapsed position disposed within the elongated body when the distal tip is in the extended position and each support arm is in a deployed position extending radially away from the elongated body when the distal tip is in the retracted position; and at least two needles being extendable and retractable relative to the elongated body, wherein each needle includes a distal end configured to penetrate through a vessel wall and capture a suture releasably held within a portion of a support arm.
