A variceal banding endoscope includes an elongated shaft having a distal end and a proximal end that is removably connected to a control unit. The endoscope includes a variceal banding apparatus fixedly attached to the distal end of the endoscope and capable of receiving a plurality of ligation bands. A trigger cable extends from the proximal end to the distal end of the shaft and is digitally actuated by an actuator in the control unit or handle of the scope in response to a user input device.
1. A medical device, comprising: an elongate shaft having a proximal end and a distal portion;a plurality of compressible structures disposed on the distal portion and arranged so that each pair of compressible structures defines a space therebetween;a plurality of compressive elements, wherein each
1. A medical device, comprising: an elongate shaft having a proximal end and a distal portion;a plurality of compressible structures disposed on the distal portion and arranged so that each pair of compressible structures defines a space therebetween;a plurality of compressive elements, wherein each compressive element corresponds to one of the plurality of compressible structures on the distal portion;a plurality of elastic members, each elastic member disposed in the space between a corresponding pair of adjacent compressible structures; andan elongate member, wherein a portion of the elongate member is coupled to each compressible structure such that, upon tension of the elongate member, one of the plurality of elastic members is released from the distal portion;wherein, prior to applying tension to the elongate member, the plurality of compressible structures extend radially outward from an exterior surface of the distal portion; andwherein, upon tension of the elongate member, one of the plurality of compressible structures is pulled toward the exterior surface of the distal portion. 2. The device of claim 1, wherein the portion of the elongate member coupled to each of the plurality of compressible structures extends through the distal portion in a loop configuration. 3. The device of claim 1, wherein the plurality of elastic members are ligation bands. 4. The device of claim 1, wherein the distal portion is translucent. 5.
