Abstract: This invention is directed to a medical device having an elongate shaft having a distal end and a controller coupled to the shaft. A control member can extend through at least part of the elongate shaft and at least part of the controller, wherein the control member in a tensioned configuration can be moveable by the controller to control the distal end of the shaft and the control member can be slack in an untensioned configuration. A tensioning mechanism can be configured to move relative to at least one of the elongate shaft and the controller to tension the control member and automatically lock the control member in the tensioned configuration.

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: The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices that lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstructions for dissection tools. In particular, the present disclosure relates to devices that transition from a constrained to an unconstrained bowed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.

Abstract: Medical devices and methods of using medical devices are disclosed. An example tissue retraction delivery device includes a positioning assembly, the assembly including: a delivery catheter having a distal end region and a lumen extending therein, wherein the distal end region includes an engagement member orienting tip. The delivery device also includes an actuation catheter extending within at least a portion of the delivery catheter, the actuation catheter including a distal end region and a lumen extending therein. An actuation wire extends within the lumen of the actuation catheter, the actuation wire having a proximal end region and a distal end region. An end effector is coupled to the distal end region of the actuation wire, the end effector configured to capture an engagement member of a tissue retraction device, wherein manipulation of the actuation wire shifts the end effector from a first position to a second closed position.

Abstract: In one aspect of the present disclosure, a tissue retraction system may include a first anchor, a second anchor, and an elongate coupling member extending between the first anchor and the second anchor. The system also may include a holder for receiving the first anchor, the second anchor, and the elongate coupling element. The holder may include a proximal portion and a distal portion. The distal portion may have a smaller width than the proximal portion such that the distal portion exerts a force on a proximal end of the first anchor during deployment of the first anchor from the holder. The force may move the first anchor into an open configuration for receiving tissue.
