Various aspects of methods, systems, and use cases may be used to deploy a light source to a targeted organ location via a working channel of an endoscope, such as in a manner that leaves the working channel free for use by another instrument and that can avoid requiring an additional channel, beyond the working channel, for illumination of a target region.

Off-axis visualization systems are described herein which facilitate the deployment, visualization, and retraction of an imaging element from a catheter. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration as well as an imaging element, such as a CCD or CMOS imager, which may be deployed from a low profile configuration into a position which is off-axis relative to a longitudinal axis of the deployment catheter and/or imaging hood.

A medical endodevice for an intervention inside a human or animal body includes an elongated liaising structure having a distal end arrangeable inside a body of the human or animal being and a proximal end arrangeable outside the body while the distal end is inside the body. The endodevice has an intervention tool arranged to manipulate a target tissue inside the human or animal body. The intervention tool is arranged at the distal end of the liaising structure. The endodevice further includes a positioning unit having a moving formation arranged to dislocate the intervention tool relative to the target tissue, and an anchoring formation arranged to fix the moving formation to a fixing tissue inside the human or animal body such that the target tissue is positioned in a workspace of the intervention tool.

According to one aspect, a dilation device may include a body, at least one loop actuator attached to the body, and a sheath attached to the body at a proximal end and attached to the loop actuator at a distal end.

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.

A system for performing minimally invasive procedures in a working space within a body lumen of a patient including a flexible catheter configured to receive a working instrument therethrough. The flexible catheter has a working space expanding system positioned at the distal portion, the working space expanding system including first and second flexible elements movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body. The first and second flexible elements are connected at a distal region by a coupling structure. A stabilizing member stabilizes the distal portion of the flexible catheter.

A stone or tissue capture device comprises a shaft with a deployable sweeping/containment structure at its distal end. The shaft is adapted to be removably placed over and connected to a conventional endoscope. The combination of the capture device and endoscope can be introduced into the various body lumens to capture, fragment/excise, and remove stones or tissue from the bladder and kidney, stomach, peritoneum, and from lumens such as the ureter, colon, hepatic ducts, airways, or blood vessels.

An apparatus and method are presented comprising an endoscope including a flexible shaft which has an active deflection section at a distal tip, a handle connected to a proximal end of the flexible shaft, a platform mounted to a top portion of the handle and oriented substantially in line with the longitudinal axis of the proximal end of a straight portion of the flexible shaft to provide a substantially straight entry into a working channel of the flexible shaft for an output accessory, a stone retrieval device insertable into the proximal end of the working channel of the endoscope, a lithotripsy shaft including one or more guide features at a distal end of the lithotripsy shaft to facilitate passage of wires or filaments of the stone retrieval device there through, and a lithotripsy shaft driver attached to the platform for driving the lithotripsy shaft under power.

A system for performing minimally invasive procedures in a body lumen of a patient including a flexible catheter having a first lumen configured and dimensioned to receive an endoscope therethrough and a second lumen configured and dimensioned to receive a first flexible tube therethrough. The first flexible tube is movable through the second lumen and has a distal portion including a first curve extending in a first direction with respect to the longitudinal axis and a second curve extending in a second different direction with respect to the longitudinal axis. A retractor system is positioned at a distal portion of the catheter and is movable from a non-expanded insertion position to an expanded position forming an expanded cage to form a larger working space. The distal portion of the first flexible tube is movable within the expanded cage.
