    Abstract: A tissue resection cap assembly configured to be secured to the distal end of an elongated medical device, such as an endoscope, and a method for resecting tissue. The cap assembly may include a cap structure comprising a working channel and a resection device channel, wherein the resection device channel extends inside the cap structure to a resection device track positioned substantially around the working channel adjacent the distal end of the cap structure. The resection device channel is adapted to direct a resection device from the working channel of the endoscope to the resection device track. The cap assembly further includes one or more ligation bands on the outside surface of the cap structure and a trigger line for deploying the ligation bands from the distal end of the cap structure. The method includes deploying a ligation band around tissue and using a resecting loop to cut the tissue.

    Abstract: A device for causing hemostasis includes a sheet of mesh stretchable between an expanded and a retracted configuration, a size of the sheet in the retracted configuration being selected to cover a target tissue site; a spring mechanism coupled to the mesh, the spring mechanism moving between an expanded configuration and a retracted configuration when the mesh is moved between the expanded and retracted configurations; and a plurality of hooks coupled to the mesh and oriented to extend into tissue to lock the mesh in position when the mesh is placed in a desired position over the target tissue site in the expanded configuration. The hooks are lockingly engaging the target tissue so that, after the hooks have lockingly engaged the tissue, the spring mechanism reverts to the retracted configuration drawing the engaged portions of tissue radially inward.

    Abstract: This invention is directed to a medical device having a longitudinal axis, and including a handle and a catheter. The handle can include a body having a proximal end and a distal end, an actuator moveably coupled to the body, and a handle control member coupled to the actuator, wherein the actuator can be configured to move relative to the body to move the handle control member. The catheter can include a shaft having a proximal end and a distal end, wherein the proximal end of the shaft and the distal end of the body can be configured for releasable coupling. The catheter can also include a steering section located along the shaft and a catheter control member coupled to the steering section, wherein the catheter control member can be configured to move relative to the shaft to move the steering section relative to the longitudinal axis. The medical device can also include a securing member configured to move relative to at least one of the handle and the catheter to releasably couple the handle control member to the catheter control member.

    Abstract: Medical devices and methods of using medical devices are disclosed. An example tissue engagement device includes a first actuation member including a body coupled to a first jaw and a second jaw at a pivot point, wherein the body is designed to shift between a first configuration and a first compressed configuration and a second actuation member coupled to the first actuation member at the pivot point and at a fixation point, wherein the second actuation member is designed to shift between a second configuration and a second compressed configuration. Further, shifting the first actuation member from the first configuration to the first compressed configuration, shifting the second actuation member from the second configuration to the second compressed configuration, or both, shifts the first jaw and the second jaw between a closed configuration and an open configuration.

    Abstract: A clipping system includes an adapter mounted on an insertion device and a clip including first and second jaws connected via hinges so that the first and second jaws are movable between an insertion configuration and an initial deployed configuration. A deployment member is configured to move the clip distally over and off of the adapter so that, as the clip leaves the adapter, the clip moves from the insertion configuration to the initial deployed configuration. An extending member is releasably coupled to the clip and movably connected to the adapter, and is configured to permit the withdrawal of the adapter away from the clip while the extending member remains coupled to the clip to place the system in a review configuration. The extending member is operable to retract the clip over the adapter, freeing the clip from tissue on which it had been clipped.

    Abstract: A closure device includes a first ring structure having a first distal portion and a first medial portion and a second ring structure having a second distal portion and a second medial portion. The first and second distal portions are movable between an open position, where the first and second distal portions form an angle relative to one another for receiving target tissue therebetween, and a closed position, where the first and second distal portions are drawn toward one another for gripping the target tissue. The device also includes an anvil about which the first and second medial portions are formed. Either one of proximal motion of the anvil relative to the first and second rings or proximal motion of the medial portions relative to the anvil causes the first and second distal portions to move into either one of the open position or the closed position.
