Abstract
Surgical method and apparatus for resectioning tissue, preferably lumenal tissue, with a remaining portion of an organ being anastomized with staples or other fastening device, preferably endolumenally. The apparatus may be inserted via a naturally occurring body orifice or a surgical incision and then advanced using either endoscopic or radiological imaging guidance to an area where surgery is to be performed. Under endoscopic or diagnostic imaging guidance the apparatus is positioned so tissue to be resected is manipulated into an inner cavity of the apparatus. The apparatus then cuts the diseased tissue after stapling and retains the diseased tissue within the apparatus. The rent resulting in a border of healthy tissue is anastomosed with surgical staples.
Claims31
A method for endolumenally resectioning lumenal tissue by anastomosing the tissue with artificial fastening means, comprising:
- a. inserting a tissue suturing and cutting instrument into a lumen of a body through a naturally occurring body orifice;
- b. advancing said instrument within said lumen to an area of undesired lumenal tissue to be resectioned;
- c. drawing said undesired lumenal tissue into a cutting zone associated with said instrument;
- d. stapling said surrounding lumenal tissue to prevent formation of an orifice;
- e. cutting said undesired lumenal tissue from surrounding lumenal tissue.
2 more elements
Apparatus for endolumenally resectioning diseased lumenal tissue and reanastomizing remaining lumenal tissue with fastening means, comprising;
- a. means for gripping lumenal tissue on respective sides of said diseased tissue and pulling said gripped tissue and said diseased tissue surrounded thereby into a cutting zone removed from an undisturbed position of said lumenal tissue;
- b. means for detaching said diseased lumenal tissue from surrounding healthy lumenal tissues;
- and
- c. means for fastening healthy lumenal tissue together across an aperture therein created by detachment of said diseased lumenal tissue from said healthy lumenal tissue, to close said aperture.

Apparatus for advancing an endolumenal operating capsule along and within a body lumen by transmitting manually applied force thereto along a curvilinear path, connecting said capsule to an operator control module external of the body and transmitting control signals from said control module to said operating capsule, comprising:
- i. a pair of annularly spaced flexible inner and outer tubular sheaths;
- ii. a plurality of serially engaging conical disks between said inner and outer sheaths, each disk comprising a plurality of radial apertures being adapted for residence of operating control signal transmission means therein, for transmitting axial force sequentially one to another as said apparatus bends to define said curvilinear path while limiting such curvilinear bending of said apparatus to a preselected degree;
- iii. longitudinally elongated means, extending the length of said apparatus and resident within the apertures of said disks, for transmitting said control signals from said control module to said operating capsule.
Apparatus for intralumenally removing undesirable tissue from a lumen wall, comprising:
- a. an endolumenal operating capsule comprising:
- i. a lip extending along a longitudinally elongated portion of said capsule;
- ii. stapling means resident in said lip for passing through tissue layers positioned on said lip and thereby securing said tissue layers together;
- iii. staple advancement and tissue cutting means movable along said lip, for advancing said stapling means through said tissue thereby effectuating securement of said tissue and cutting said tissue layers inboard of said tissue securement;
- b. tubular apparatus for positioning said capsule along and within said lumen by transmitting manually applied force thereto along a curvilinear path as said tubular apparatus bends to define said curvilinear path while limiting such curvilinear bending of said tubular apparatus to a preselected degree, said tubular apparatus connecting said capsule to an operator control module external of the body and transmitting control signals from said control module to said operating capsule, comprising:
- i. a pair of annularly spaced flexible inner and outer tubular sheaths;
- ii. longitudinally elongated means, extending the length of said tubular apparatus between said inner and outer sheaths, for transmitting said control signals from said control module to said operating capsule;
- iii. means between said inner and outer sheaths for maintaining said longitudinally extending control signal transmission means in circumferentially spaced relation to one another and transmitting capsule positioning force along a curvilinear path as said tubular apparatus bends to define said curvilinear path while limiting such curvilinear bending of said tubular apparatus to a preselected degree;
- c. said operator control module for converting operator tactile motions to signals controlling operation of said capsule for input to said control signal transmission means;
- and
- d. an endoscope slidably resident within said inner sheath and said operating capsule.

A method for endolumenally cylindrically resectioning lumenal tissue comprising:
- a. inserting a tissue suturing and cutting instrument into a body lumen through a naturally occurring body orifice;
- b. advancing said instrument within said lumen to an area of undesired lumenal tissue to be cylindrically resectioned;
- c. drawing said undesired cylindrical lumenal tissue into an annular cutting zone associated with said instrument;
- d. stapling said surrounding lumenal tissue about annular margins of said cylindrical tissue to prevent the formation of an orifice;
- e. cutting said undesired cylindrical lumenal tissue from surrounding lumenal tissue.
