Patent Images
1. An apparatus for use with an endoscope having a generally circular cross-section, the apparatus comprising:
- a flexible sheath having an outer surface and an inner surface, the sheath adapted for receiving the endoscope with a generally circular cross-section and for permitting circumferential motion of the endoscope relative to the sheath;
a track in the form of a rail disposed on the outer surface of the sheath;
a mating member in sliding engagement with the rail of the track, wherein the mating member has a length substantially equal to or greater than the length of the rail; and
an accessory, wherein the accessory is secured to the mating member by a flexible flange, wherein the flexible flange extends unitarily between the mating member and the accessory, wherein the flange extends in a radially outward direction relative to the sheath, wherein the accessory, the mating member, and the flexible flange are adapted to slide as a unit along the track external of the endoscope; and
wherein the track is disposed on a second flexible flange.

11. An apparatus for use with an endoscope, the apparatus comprising:
-
a flexible sheath adapted to receive an endoscope; a handle disposed at a proximal end of the flexible sheath and having a through bore for receiving an endoscope; a track extending along at least a portion of the length of the flexible sheath, wherein the track is capable of moving circumferentially with respect to the endoscope and assuming a curved path outside the plane of curvature of the endoscope when the endoscope takes on a curved configuration, wherein the track is disposed on a first flexible flange, wherein the first flexible flange extends between the track and the flexible sheath in a radial direction;
a medical accessory adapted to engage the track and slide along the track anda mating member in sliding engagement with the track, wherein the mating member has a length substantially equal to or greater than the length of the track, wherein the mating member includes a second flexible flange coupling the mating member with the medical accessory, wherein the mating member extends between the mating member and the medical accessory, wherein the second flexible flange extends in a radial direction. - View Dependent Claims (12)
