An integrated endoscope and accessory treatment device is provided. The device employs a medical treatment device at its distal end that is combined with the endoscope as a complete system. The treatment device is controlled by integrated elements at the proximal end of the endoscope. The treatment devices may include tissue apposition devices, tissue cutting devices, forceps and others.

Integrated endoscope and accessory treatment device

The present invention provides an endoscopic accessory control system that resides externally of the endoscope. The system comprises the endoscopic accessory with a working end to be placed at the distal end of the endoscope, a control sheath extending proximally external to the endoscope and a control handle joined to the proximal end of the control sheath. The control handle is slidably mounted to the exterior surface of the endoscope shaft and is configured to permit grasping of both the shaft and the handle. With the control handle and endoscope shaft grasped with one hand, the other hand of the user is left free to manipulate the endoscope distal tip controls. Additionally, the external arrangement of the control sheath leaves the working channel of the endoscope free for use of accessories or operations.

External endoscopic accessory control system

The present invention provides a ligating band dispenser that is mounted on the distal end of an endoscope. The ligator is configured to deliver multiple ligating bands to a plurality of internal sites in a patient. The ligating bands are carried on a tubular band carrier member that is retractable relative to the distal end of the endoscope in order to preserve visibility through the endoscope during navigation, then extendable to define a suction chamber for tissue aspiration during band delivery. A tubular band driver member is slidable over the band carrier member and engages bands individually to push them off the distal end of the band carrier and onto a selected treatment site. A single-hand operated control handle for selectively operating the extension of the band carrier and movement of the band driver to release a band is also provided and is slidably and removably mounted to the endoscope shaft.
