Apparatus and methods for forming and securing gastrointestinal tissue folds
First Claim
1. An endoscopic system for suturing tissue, comprising:
- a needle adapted to suture an area of tissue, the needle being removable from a distal end of an endoscopic device;
an urging mechanism adapted to move the needle from a deployment configuration to a suturing configuration in which the needle is angled relative to the endoscopic device; and
wherein the needle defines at least one opening through which a suture is passed from a first side of tissue to a second side of tissue.

Abstract
Apparatus and methods are provided for forming a gastrointestinal tissue fold by engaging tissue at a first tissue contact point and moving the first tissue contact point from a position initially distal to, or in line with, a second tissue contact point to a position proximal of the second contact point, thereby forming the tissue fold, and extending an anchor assembly through the tissue fold from a vicinity of the second tissue contact point. Adjustable anchor assemblies; as well as anchor delivery systems, shape-lockable guides and methods for endoluminally performing medical procedures, such as gastric reduction, treatment of gastroesophageal reflux disease, resection of lesions, and treatment of bleeding sites; are also provided.

17. A method of suturing tissue within a hollow body organ, comprising:
-
positioning an endoscopic device relative to a tissue region within the hollow body organ;
piercing the tissue whereby a needle assembly travels a curved path through a flexible tubular member, the needle assembly being removable from a distal end of the endoscopic device; and
passing a length of suture through the tissue via a needle body at a distal end of the needle assembly, the needle body defining at least one opening through which the suture is passed through the tissue. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. An endoscopic treatment apparatus, comprising:
-
an endoscopic device having a proximal end, a distal end, and a flexible length therebetween;
a needle assembly which is adapted to travel a curved path to suture an area of tissue, the needle assembly being actuatable from the proximal end of the endoscopic device to direct the needle assembly to the curved path; and
a tissue stabilizing member projecting pivotally and translationally from the distal end of the endoscopic device, the stabilizing member being adapted to hold onto the tissue when the tissue is pierced by the needle assembly. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A system for endoscopic treatment of tissue, comprising:
-
an endoscopic device having a proximal end, a distal end, and a flexible length therebetween;
a needle assembly which is adapted to suture an area of tissue, the needle assembly being actuatable from the proximal end of the endoscopic device to direct the needle assembly over a curved path;
a tissue stabilizing member projecting pivotally and translationally from the distal end of the endoscopic device, the stabilizing member being adapted to stabilize the tissue when the tissue is pierced by the needle assembly; and
a tissue anchoring assembly adapted to be deployed from the needle assembly for securing the tissue. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47)

48. A method of endoscopically treating tissue within a hollow body organ, comprising:
-
positioning a distal end of an endoscopic device relative to a region of tissue within the hollow body organ;
stabilizing the tissue via a stabilizing member projecting pivotally and translationally from the distal end of the endoscopic device;
piercing the tissue with a needle assembly which is adapted to suture the tissue by actuating the needle assembly from a proximal end of the endoscopic device such that the needle assembly is directed over a curved path; and
passing a length of suture through the tissue via the needle assembly. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56)
