Abstract:
A surgical device comprises an elongate shaft defining a longitudinal axis. The shaft comprises a distal end and a proximal end. An arm medially deflectable and comprises a mating feature. An elongate pin is positioned medially relative the arm. The elongate pin is axially slideable relative the arm between a locked position preventing medial deflection of the arm and an unlocked position allowing medial deflection of the arm. An energy based surgical end effector is selectively attachable and detachable to the mating feature of the arm. The end effector may include a torque arm to engage the elongate shaft.
Abstract:
Suture holding devices and methods are disclosed, including devices and methods useful in performing a transoral surgical procedure, such as a posterior gastroplexy procedure A device (200) is disclosed which can be used by a physician in a medical procedure to automatically lock and cut a suture in one motion and without the need for additional cutting instrumentation, rather than perform separate locking and cutting actions
Abstract:
Suture anchoring devices are disclosed, including a T-tag anchoring device (100) that is suitably small enough to fit into the hollow tip of a needle (152) and, furthermore, provide protection to a suture (150) against being cut or otherwise damaged by (he sharp edge of the needle tip (154). One disclosed device (100) includes a slot (112) for providing a pivot point between the suture (150) and the device body (110) when deployed, which can be employed to form a T-tag (100).
Abstract:
Devices and methods are provided which may be used for suturing, including performing a totally transoral surgical procedure, such as a posterior gastroplexy procedure. A suture lock and cut assembly (100) is provided to lock and cut one or more sutures (136) in one motion, which motion can be a non-curved, non-rotational linear motion. The suture lock and cut assembly (100) with one or more sutures (136) threaded therethrough may be pushed through, for example, a patient's esophagus and into the stomach by the tip of an endoscope, or alternatively, sized to be fed through the working channel of the endoscope.
Abstract:
A surgical device comprises an ex vivo magnet and an in vivo sled magnetically attracted to the ex vivo magnet. The sled can be positioned and anchored within a patient by moving the ex vivo magnet. The sled defines a longitudinal axis. An arm extends from the sled. The arm being moveable relative the sled between a retracted position and an extended position. The arm comprises an end effector. A longitudinally oriented screw operatively is connected to the sled and arm such that rotation of the screw moves the arm between the retracted and extended positions.
Abstract:
Various exemplary methods and devices are provided for manipulating and/or anchoring devices and body parts during surgical procedures. In one embodiment, an anchor member is provided for anchoring a device or body part to tissue, such as an internal wall of a body cavity. The device can be, for example, an endoscopic device, an accessory channel coupled to an endoscopic device, or a support member adapted to support or manipulate an organ. The anchor member can include or form an opening through which the device can be inserted. The anchor member or device can thus be manipulated relative to the tissue to control movement of and/or provide support to the device, tools inserted through the device, and/or organs grasped by the device or tools.
Abstract:
Methods and devices are provided for controlling movement of a working end of a surgical device (10,100), and in particular for performing various surgical procedures using an instrument having an end effector that can be articulated relative to an elongate shaft of the device. A decoupling member (70,170) can isolate the actuation of the end effector (14,108) from the articulation of the end effector. In certain embodiments, the end effector can also optionally rotate relative to the elongate shaft (12,106) of the device, and/or the shaft can rotate relative to a handle of the device.
