The present embodiments provide systems and methods suitable for delivering a therapeutic agent to a target site. In one example, the system comprises a container for holding the therapeutic agent, and a pressure source having pressurized fluid, wherein the pressure source is in selective fluid communication with at least a portion of the container. A catheter is placed in fluid communication with the container, and has a lumen sized for delivery of the therapeutic agent to a target site. A housing is configured to securely retain the container. The system further comprises a camera having a camera head coupled to the catheter, wherein the camera provides a visual image of the target site during delivery of the therapeutic agent.

Devices and methods for delivering and filtering a gas to a wound site to enhance healing, reduce the potential for bacterial infections, lessen the need for antibiotics and to create a protective and therapeutic gas atmosphere along a treatment site. More particularly, the invention relates to a device arranged to deliver a gas to a treatment site, the device being connectable to a gas source, the device including (i) a first membrane comprising a flexible, microporous polymer body and (ii) a second membrane comprising a flexible nonporous polymer body. Outer edge portions of the second membrane are bonded to outer edge portions of the first membrane to form an interior chamber of the device, the interior chamber of the device confining introduced gas to the interior chamber such that the introduced gas flows out through the pores of the first membrane and is diffused along the treatment site.

A medical device includes a device body and an insufflation fitting coupled to and extending from the device body. The insufflation fitting includes an annular high-flow fitting portion and an annular low-flow fitting portion extending away from the device body from the annular high-flow fitting portion. The annular high-flow fitting portion includes a first inner surface and a radially outward sealing surface generally reverse from the first inner surface. The annular low-flow fitting portion includes an inner sealing surface and a first radially outward surface generally reverse from the inner sealing surface. The first inner surface of the annular high-flow fitting portion and the inner sealing surface of the annular low-flow fitting portion define an insufflation gas flow passageway through the insufflation fitting.

Systems, methods, and workflows for concomitant procedures are disclosed. In one aspect, the method includes manipulating a flexible instrument using a first robotic arm of a robotic system, manipulating a rigid instrument using a second robotic arm of the robotic system, displaying feedback from the flexible instrument, and displaying feedback from the rigid instrument.

One aspect of the invention provides a trocar including: a central cylinder defining a central channel and having a distal end adapted and configured for insertion within a subject; one or more gas outlets located within the central cylinder proximate to the distal end of the trocar; and one or more liquid outlets located within the central cylinder on a proximal side of the one or more gas outlets. The one or more liquid outlets are adapted and configured to dispense a liquid when an endoscope is withdrawn from a fully extended position within the central channel of the trocar to a position proximate to the one or more liquid outlets. Distal advancement of the endoscope to a position adjacent to the one or more gas outlets removes liquid from a distal end of the endoscope.

A method of operating a manipulator arm comprising a manipulator interface configured to removably couple with and transmit actuation force to a medical instrument includes mounting a cannula to a cannula mount coupled to the manipulator arm; mounting a medical instrument to the manipulator interface; inserting a shaft of the medical instrument through an entry guide mounted to the cannula; rotating the manipulator interface and the medical instrument relative to the cannula mount; and rotating the entry guide relative to the cannula mount about a longitudinal axis of the cannula.
