Abstract: 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.

Abstract: A method of treating a lesion in a gastrointestinal tract and an injectate system are provided. The method includes injecting a crosslinkable gel into a first tissue layer, the crosslinkable gel increasing a volume of the first tissue layer. The method also includes providing a crosslinker and resecting a portion of a first tissue layer having the increased volume away from a second tissue layer creating an exposed region in a remaining portion of the first layer and leaving a portion of the gel covering at least a portion of the exposed region. The injectate system includes a crosslinkable gel and a crosslinker where the crosslinkable gel and the crosslinker form a crosslinked gel having a compressive modulus of about 10-500 kPa.

Abstract: An endoscopic device is provided. The endoscopic device may comprise a distal end and a proximal end. The proximal end may be opposite the distal end. The endoscopic device may further comprise a handle at the proximal end and a tube extending from the handle towards the distal end of the endoscopic device. The endoscopic device may further comprise an accessory channel. The accessory channel may extend through the tube. The endoscopic device may further comprise a slide, the accessory channel connected to the slide, and a track disposed adjacent to the proximal end of the endoscopic device. The slide is movable within the track to cause movement of the accessory channel within the tube.
