A surgical clip has a base portion and two generally parallel, spaced arms extending from the base portion and defining an opening therebetween. The arms terminate distally in fingers which are of reduced width and thickness relative to the arms and which are adapted to be bent towards and past each other. A transition section from each arm to the finger provides curved structures which extending away from each other and providing a wider mouth for the opening between the arms. The arms also have a proximal section with an undercut which helps in flexure of the arms. The base is an extended structure having a rounded proximal end with outwardly extending shoulders which are arranged to be engaged by the curved structures of the mouth of another clip.

A tissue retractor includes a body having proximal and distal ends. The retractor also includes a retraction device having a head connected to the distal end of the body and defining two opposing openings, a connector movably disposed in the body, and two flexible needles of a shape memory material having a memory shape. The needles are fixedly connected to the connector for traveling through a respective one of the openings. The memory shape of the needles includes a portion with an arcuate shape. A one-handed actuation device is connected to the proximal end of the body and is operatively connected to the connector through the body. Upon actuation of the actuation device, the connector can be moved to selectively extend the needles out of the head and withdraw the needles into the head. Methods for using the tissue retractor, in particular for the treatment of Gastroesophageal Reflux Disease, are also provided.

A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.

A retractor for manipulating an object includes a body having proximal and distal ends and a retraction device with a head connected to the distal end of the body, a connector movably disposed in the body, and flexible needles of a shape memory material having a memory shape. The needles are connected to the connector and each have a distal tip. The memory shape of the needles include a portion with an arcuate shape biasing the needles in a memory direction out and away from the head and toward the body to position the distal tip of each of the needles closer to the body when the needles are fully extended out of the head than when the needles are only partially extended out of the head. An actuation device is connected to the proximal end of the body and operatively connected to the connector through the body, the actuation device, upon actuation thereof, moves the connector to selectively extend the needles out of the head in different directions and withdraw the needles into the head.
