A suturing kit includes a double - armed suture, at least one suturing device and a suture holding structure. The double - armed suture has a first needle at a first end and a second needle at a second, opposite, end. The at least one suturing device includes a first needle holder configured to receive the first needle in a retracted position, a second needle holder configured to receive the second needle in a retracted position and at least one actuator configured to drive the first needle or the second needle in an advance direction toward a released condition. The suture holding structure holds at least a portion of the suture between the first end and the second end, and the suture holding structure is separate from the at least one suturing device so as not to be inserted into the patient during the surgical procedure.

Devices and methods for the suture repair of tissue are disclosed. An apparatus includes a handle, a needle assembly, and an actuator. The handle has a proximal end portion and a distal end portion. The needle assembly is configured to be transitioned between a first configuration and a second configuration, and includes a first needle and a first capture member. The actuator is movably coupled to the handle and includes a first coupling portion operably coupled to the needle assembly. The first coupling portion is configured to move relative to the handle in response to a first force to transition the first needle assembly from the first configuration in which the first capture member is spaced apart from the first needle to the second configuration in which the first capture member engages the first needle. Methods of suture repair are also disclosed.
摘要:
A suture-based vessel closure device is configured to close a carotid artery puncture site. The suture-based vessel closure device can place one or more sutures across the vessel access site such that, when the suture ends are tied off after sheath removal, the stitch or stitches provide hemostasis to the access site. The sutures can be applied either prior to insertion of a procedural sheath through the arteriotomy or after removal of the sheath from the arteriotomy.

A balloon catheter visualization system for repairing a heart valve in a patent includes one or more elongate shafts, each shaft defining at least one lumen and comprising a distal end portion and a proximal end portion. The system also includes a transparent balloon member coupled to the one or more elongate shafts and is in fluid communication with at least one lumen of the one or more elongate shafts. The system also includes an imaging element disposed within the balloon member and coupled to a distal end portion of the one or more elongate shafts, a fastener releasably coupled to a distal end portion of the one or more elongate shafts, and a connector coupled to a distal end portion of the one or more elongate shafts. The connector is adapted to fasten the fastener to tissue.

According to embodiments of the present invention, a subcutaneous implant delivery apparatus is provided. The apparatus includes a receiving portion configured to receive a subcutaneous implantable device; and a stabilizing portion configured to cooperate with the receiving portion to hold the subcutaneous implantable device in a fixed position. The receiving portion and the stabilizing portion are movable relative to each other between a released configuration, wherein the receiving portion and the stabilizing portion are configured to move apart from each other to allow the receiving portion to be inserted under a skin layer, and a closed configuration, wherein the receiving portion and the stabilizing portion are configured to move toward each other to allow the subcutaneous implantable device to be held adjacent to the skin layer. According to further embodiments of the present invention, a method of delivering a subcutaneous implantable device for accessing a vascular site is also provided.

Suture passers having pre-tied suture knots and methods of use. Described herein are suture passers preloaded with suture and pre-tied suture knots, including cartridges that couple to a suture passer to form a loaded suture passer; the suture passer may be operated to pass one or more lengths of suture and a pre-tied knot for knotting the suture without having to be manually reloaded. In particular, described herein are preloaded and automatically reloading apparatuses typically.
摘要:
Suturing devices and systems used to apply sutures and/or to close openings at, within, or into a biological structure. The suturing device can comprise an elongate member having a proximal end, a distal end, one or more distal arms, one or more proximal extensions, and one or more needles. A sheath may be used with the device to maintain or substantially maintain haemostasis while the device is used and while a procedure is performed in the biological structure.
