Abstract: The present disclosure relates to tissue traction devices and systems. In one example, a tissue tensioning system may include a filament having a first end comprising an attachment member, a second end, and a length therebetween extendable externally along a catheter. A first tissue fastener may be engageable with the attachment member and with a target tissue. The second end of the filament may be translatable to adjust a tensional force along the filament.

Abstract: Described herein are drive systems and methods. One exemplary system includes a tool having a proximal handle and a catheter body. The tool can be mated with a rail and the rail mated with a frame. The connection between the tool and rail and/or the rail and frame can allow relative movement of the tool with respect to the frame, a patient, and/or a point of reference. In one exemplary configuration the handle of the tool rotates around an axis that corresponds to a portion of the catheter body, such that rotational movement of the handle has a minimal impact on longitudinal movement and/or position of a distal end of the tool.

IPC: A61B17/32

Abstract: A filament cutting device may include an outer sheath. A bushing may be coupled to a distal end of the outer sheath. An inner diameter of the bushing may be a cutting edge at a distal tip of the bushing. An actuation wire may be slidably extendable within the outer sheath and bushing. An engaging body may be coupled to a distal end of the actuation wire. A cavity may be defined along a length of the engaging body configured to capture a portion of the filament within the cavity. Movement of the actuation wire and engaging body with the filament captured within the cavity may cause the cutting edge to sever the filament.

Abstract: Various embodiments are generally directed to a flexible elongate member (e.g., endoscopic accessory tool) positionable into and/or through selected anatomies, such as by generating images to position components of a flexible elongate member or to localize anatomic features, for instance. Some embodiments are directed to generating images with a plurality of imaging techniques to localize anatomic features and/or components of a flexible elongate member for one or more of inspection, orientation, and/or facilitating access to body passageways or lumens.

Abstract: Various embodiments are generally directed to positioning techniques to facilitate entry of a flexible elongate member (e.g., endoscopic accessory tool) into and/or through selected anatomies, such as by directing a set of positional controls based on feedback from a set of transducers to achieve or maintain a position within a body lumen, for instance. Some embodiments are particularly directed to a feedback loop for positioning or guiding a flexible elongate member into a target configuration for one or more of inspection, orientation, and/or facilitating access to body passageways. In one embodiment, for example, a device manager may include circuitry to operate at least one positional control in a set of positional controls based on data indicative of a current configuration of a flexible elongate member generated by a set of transducers.

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: An instrument for use with an endoscope may include an elongate section configured to move exterior to the endoscope. The elongate section may include a distal end and a proximal end. The instrument may also include an end effector attached to the distal end of the elongate section, and an actuation device attached to the proximal end of the elongate section. The actuation device may be configured to operate the end effector. The instrument may also include a guiding member coupled to the elongate section. The guiding member may be configured to be coupled to an external surface of the endoscope to permit the guiding member to move longitudinally relative to the endoscope. The guiding member may be coupled to the elongate section such that the end effector may extend past a distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope.
