Abstract: An endoscopic surgical device used for minimally invasive procedures comprises a handheld component and a power control module. The handheld component consisting of a handle, and a conduit houses a wireless imaging module and a single LED light source. The imaging module comprises a wired or wireless camera coupled to an optically folded assembly or imaging assembly. A battery-operated power module can control both the intensity of the LED and the camera action. The handle and conduit are designed to accommodate surgical tools, wherein the imaging model is parallel offset to the tool, or the tool are parallel offset to the imaging. In alternative embodiments, the handheld component is self-contained.

Abstract: A catheter assembly having a balloon disposed at the distal end thereof and a therapeutic substance delivery assembly, including a needle in fluid communication with a therapeutic substance delivery lumen for allowing a therapeutic substance to be injected into a diseased physiological lumen. A deflector is positioned along an inside wall of the delivery lumen, positioned, such that as a bend region forms caused by the movement of the delivery lumen, the deflector bends to rest on the outside curvature of the bend. As the needle is made to travel through the bend, the ribbon helps to bounce the needle tip off the wall of the delivery lumen, allowing the needle to travel through the bend without digging into and/or gouging the delivery lumen wall.
