    摘要： A steerable, tendon-driven endoscope is described herein. The endoscope has an elongated body with a manually or selectively steerable distal portion and an automatically controlled, segmented proximal portion. The steerable distal portion and the segment of the controllable portion are actuated by at least two tendons. As the endoscope is advanced, the user maneuvers the distal portion, and a motion controller actuates tendons in the segmented proximal portion so that the proximal portion assumes the selected curve of the selectively steerable distal portion. By this method the selected curves are propagated along the endoscope body so that the endoscope largely conforms to the pathway selected. When the endoscope is withdrawn proximally, the selected curves can propagate distally along the endoscope body. This allows the endoscope to negotiate tortuous curves along a desired path through or around and between organs within the body.

    摘要： Devices and methods for cutting and collecting a specimen from a mass of tissue. The device may include an integrated cut and collect assembly. The integrated cut and collect assembly includes a cutting portion and a collection portion that includes a flexible membrane. The collection portion of the assembly is attached to the cutting portion thereof. The cutting portion is configured to cut the specimen from the mass of tissue and the collection portion is configured to collect the cut specimen and to encapsulate and isolate the cut specimen within the membrane to enable its safe retraction from the mass of tissue.

    摘要： A sheath holds a device against a balloon catheter for delivery in the lumen of a patient. The device can be a stent and graft combination. The stent is kept properly centered over the balloon catheter by the sheath as the graft is placed in a blood vessel. The smooth outer surface of the sheath protects the vessel wall from the rough surface of the stent. A notch is formed in the end of the sheath where the free end of a strand of thread protrudes from the sheath. The sheath is removed from the graft by pulling on the free end of the strand otherwise located distally from the outer surface of the sheath. The strand cuts through and splits open the sheath as a result of the force applied on the free end of the strand. The other end of the strand is attached to a reinforced collar at the other end of the sheath. The strand does not cut through the collar. After reaching the collar, the proximal force applied on the strand now pulls the split sheath from the graft and stent combination without disturbing the placement of the stent over the balloon delivery catheter.
