    Abstract: A suture device for use in combination with a delivery system including a lumen extending through the delivery system includes a needle usable to carry a suture, a distal shuttle configured to releasably secure the needle, a sleeve disposable over the distal shuttle, the distal shuttle movable relative to the sleeve between a locked position in which the needle is locked to the distal shuttle and an unlocked position in which the needle is releasable from the distal shuttle. The suture device includes a distal assembly including an elongate tool guide movable between a deployment configuration in which the elongate tool guide is substantially parallel with the distal assembly and a working configuration in which the elongate tool guide curves away from the distal assembly.

    Abstract: According to one aspect, a medical device may be configured for use with an endoscope and may include a tool. The tool may include an actuator, at least one extension at a distal portion of the actuator, and a distal end. The at least one extension may extend radially outward from the actuator and may have an edge configured to fragment debris within a body. The medical device may also include a cap configured for coupling to a distal end of the endoscope, and the cap may include a body defining an opening and a cavity. The opening may be configured to align with optics of the endoscope, and the at least one extension may be positioned within the cavity of the body.

    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.
