INTRALUMENAL ACCESSORY TIP FOR ENDOSCOPIC SHEATH ARRANGEMENTS
First Claim
1. An intralumenal accessory tip for attachment to an inner sheath assembly having a housing and at least one flexible access tube and an endoscopic tool protruding from a distal end of the housing, said intralumenal accessory tip comprising:
- a body portion having a distal end and a proximal end, said proximal end configured for removable attachment to the housing;
a tool-receiving passage corresponding to the endoscopic tool and sized to receive the endoscopic tool therein when said proximal end of said body portion is attached to the distal end of the housing such that no part of the endoscopic tool protrudes beyond said distal end of said body portion; and
a tube-receiving passage sized to receive at least one of the at least one flexible access tubes therein when said proximal end of said body portion is attached to the distal end of the housing such that no portion of the at least one flexible access tube protrudes beyond said distal end of said body portion.

Abstract
An intralumenal accessory tip for use with an inner sheath assembly during initial insertion of the inner sheath into a patient. The intralumenal accessory tip is removably attachable to the distal end of the inner sheath assembly and has passages therein to accommodate access tubes and endoscopic tools protruding from the inner sheath assembly. The intralumenal accessory tip may be attached to the distal end of the inner sheath assembly and both assemblies may be inserted into an overtube to permit the inner sheath assembly to be inserted into the patient. The inner sheath assembly may then be withdrawn out of the overtube and the intralumenal tip accessory removed therefrom.

10. An intralumenal accessory tip for attachment to an inner sheath assembly having a housing and two articulatable access tubes protruding therefrom and an endoscopic camera having a selectively movable end portion protruding from a distal end of the housing, said intralumenal accessory tip comprising:
-
a body portion having a distal end and a proximal end; means for removably attaching said proximal end of said body portion to the distal end of the housing; tube access means in said body portion for accommodating the two articulatable access tubes when said body portion is attached to the distal end of the housing; and tool access means in said body portion for accommodating the endoscopic camera therein when said body portion is attached to the distal end of the housing. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A surgical method comprising:
-
attaching an intralumenal accessory tip onto a distal end of an internal sheath assembly such that all of any an portions of accessory tubes and endoscopic tools protruding from the distal end of the internal sheath assembly are received within the intralumenal accessory tip and do not protrude beyond a distal end of the intralumenal accessory tip; inserting an overtube over the internal sheath assembly and intralumenal accessory tip such that a distal end of the overtube is located in a desired position relative to the intralumenal accessory tip; inserting the intralumenal accessory tip, a portion of internal sheath assembly, and the overtube into a patient such that the intralumenal accessory tip is located in a desired area; withdrawing the internal sheath assembly and intralumenal accessory tip out through the proximal end of the overtube while retaining the overtube in place; removing the intralumenal accessory tip from the distal end of the internal sheath assembly; and reinserting the internal sheath assembly into the overtube to the desired area. - View Dependent Claims (20, 21, 22, 23)
