摘要： This disclosure relates to the field of luminal surgery. Specifically, the present disclosure relates to medical devices that expand within a body lumen for accessing a target tissue. In an aspect, an expandable device for a body lumen may include a filament comprising a proximal end, a distal end, and a length. The device may include a plurality of segments. Each segment may comprise a middle portion comprising a longitudinal axis extending axially therethrough, a projection portion extending from an end of the middle portion along the longitudinal axis, and a receptive portion extending from an opposing end of the middle portion away from the longitudinal axis, the receptive portion configured to receive the projection portion of an adjacent one of the plurality of segments. An aperture may be disposed through the projection portion, the middle portion, and the receptive portion.

摘要： 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.

摘要： 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.

摘要： A clipping system includes an adapter configured to be mounted over an insertion device and a clip including first and second jaws movable between an insertion configuration and an initial deployed configuration. A first extending member is releasably coupled to the clip and movably connected to the adapter to permit a movement of the clip relative to the adapter from the insertion configuration to the initial deployed configuration. The first extending member is configured to permit withdrawal of the adapter away from the clip to place the system in a review configuration to enhance a visual observation of the clip. The first extending member is operable to retract the clip over the adapter so that the clip is forced open, freeing the clip from tissue on which it has been clipped. The first extending member is configured to release the clip therefrom in a final deployed configuration.

摘要： A device for treating hemorrhoids includes a housing sized and shaped for insertion to a target site within a rectum. The device also includes an inner member received within the housing such that the member may move longitudinally relative to the housing. In addition, the device includes a ligating mechanism at a distal end of the member which includes grasping arms movable between a receiving configuration in which distal ends of the arms are separated from one another and a grasping configuration in which the distal ends are drawn together to grasp tissue. The mechanism includes a ligating band received around the arms that is movable distally off of the arms to constrict around tissue grasped by the arms.

摘要： A device includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough. The capsule is releasably coupled to a proximal portion of the device. Device also includes a first arm rigidly fixed to the distal end of the capsule to extend distally therefrom. In addition, Device includes a second arm, a proximal end of which is slidably received within the capsule so that the second arm is movable between an open configuration, in which the second arm is moved laterally away from the first arm and a distal end of the second arm is moved distally past the distal end of the first arm, and a closed configuration, in which the second arm is moved toward the first arm and the distal end of the second arm is moved proximally toward the distal end of the first arm.

摘要： According to one aspect, a guidewire assembly for positioning within a body of a patient may include a guidewire shaft having a proximal section and a distal section. The distal section may be configured to move within the body of a patient when the guidewire assembly is in a first operating state. The distal section may be configured to expand radially outward when the guidewire assembly is in a second operating state to engage an interior surface of the body and inhibit movement of the guidewire shaft.

摘要： A tissue closure device includes a needle and a suture extending therefrom, a proximal head including a proximal slot and a proximal locking mechanism for releasably engaging a first end of the needle in the proximal slot in a first configuration, and a distal head movably coupled to the proximal head so that the proximal and distal heads are movable relative to one another between an open configuration, in which a target tissue is received therebetween, and a closed configuration, in which the target tissue gripped therebetween. The distal head includes a distal slot and a distal locking mechanism for releasably engaging a second end of the needle in the distal slot in a second configuration, the needle movable between the first and second configurations by rotating the needle, the needle alternatingly passed between the proximal and distal heads to thread the suture through the target tissue.
