摘要:
A suture passer comprising: a shaft having an axis; a first jaw mounted to the shaft in alignment with the axis, the first jaw being configured to releasably support a length of suture thereon; a second jaw movably mounted to the shaft; and a needle movably mounted to the shaft, the needle having a hook and being configured to reciprocate in alignment with the axis so that the hook can selectively pass by the second jaw and engage suture releasably supported on the first jaw; wherein the first jaw comprises a spring for selectively binding the suture to the first jaw, and further wherein the spring comprises a recess for receiving the suture therein.

A suture passer comprising: a hollow tube, the hollow tube comprising a distal end, a proximal end, a lumen extending from the distal end to the proximal end, and a window formed in the sidewall of the hollow tube, the window communicating with the lumen; and a clamping rod slidably received in the lumen of the hollow tube, the clamping rod comprising a distal end and a proximal end, the distal end being bifurcated into a first arm and a second arm, one of the first and second arms extending distally of the other of the first and second arms and including a clamping surface, and at least one of the first and second arms being outwardly biased such that when the clamping rod is moved distally so that the distal end of the at least one outwardly biased arm is adjacent to the window, the distal end of the at least one outwardly biased arm extends outwardly through the window.

A medical device (10) includes an articulating shaft (20, 20a, 20b, 20c, 20d, 20e, or 20f) with a pair of slat assemblies (31, 33). By moving an articulator (37), the slat assemblies (31, 33) are configured to concurrently push while the other pulls in order to bend the articulating shaft (20). The articulating shaft (20) includes a series of pivot members (26, 26a, 26b, 26c, 26d, 126e and 226e, or 126f and 226f). The pivot members (26) may include inner links (126e, 126f) and outer links (226e, 226f). A method for articulating a shaft of a medical device is also provided.
摘要:
Tissue holding implants which enable two or more layers of tissue to be held in approximation for an extended period. One and two-piece implants are described, made from materials that are biocompatible, and may also be biodegradable. Some embodiments include a portion which is deformed to capture the tissues to be held, and others are made from a super-elastic or shape memory material and hold the tissues in approximation when the implant is reverted to a known preformed shape.
摘要:
A medical device with an articulating shaft assembly includes at least one slat member which has a cross section that allows it to be substantially flexible in a first plane and relatively stiff in the plane perpendicular to the first plane. A bendable section located at the working end of the device includes at least a portion of one or more slat members, such that the bendable section will articulate in the first plane in response to tensive and/or compressive forces applied to the bendable section. The device also includes a shaft section which is coupled to and supports the bendable section, and at least one control mechanism arranged to cause the tensive and/or compressive forces needed to articulate the bendable section to be applied to the bendable section.

摘要:
A tissue positioning device comprising a biocompatible member having a size and shape suitable for placement within a space adjacent to a tissue to be positioned and which acts to maintain the tissue in a desired position. The member may be a rigid or flexible spacer having a defined shape, or a bladder capable of receiving and being at least partially expanded by a filler material. The device can made from a variety of materials or a composite of materials as needed, and may include one or more attachment means by which it can be secured to nearby tissues such that it is maintained in a desired spatial location. The filler material can be any of a number of substances, including liquids, gases, a curable liquid such as bone cement or urethane foam, or a spring.
