摘要： A wireless endoscopic surgical device used for minimally invasive procedures comprises a handheld component and a separate power module. The handheld component consisting of a handle and a conduit houses a wireless imaging system and a single LED light source. The imaging system comprises a wireless camera coupled to an optical assembly. Both the intensity of the LED and the camera action can be controlled by a battery-operated power module. The handle and conduit are designed to accommodate surgical tools.

摘要： 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.
摘要翻译：一种具有设置在其远端处的气囊的导管组件和包括与治疗物质输送腔流体连通的针的治疗物质输送组件，用于允许将治疗物质注射到患病的生理管腔中。偏转器沿着输送腔的内壁定位，定位成使得由于由输送腔的运动引起的弯曲区域形成，偏转器弯曲以弯曲的外侧曲率。当针被制造成穿过弯曲部时，带状物有助于使针尖从输送腔的壁反弹，从而允许针穿过弯曲部而不会进入和/或凿出输送腔壁。
