Abstract:
A method for forming an anastomosis between first and second organs in a patient using a hollow receptacle that is inflatable with magnetic material. The method may include forming openings through the first and second organs utilizing a hole-forming instrument inserted into the organs through a natural orifice in the patient. The hollow receptacle may be supported on a catheter assembly that is also inserted through the patient's natural orifice and through the openings in the first and second organs and is positioned within the second organ. The hollow receptacle is then inflated with magnetic material and magnetic force is applied within the force organ to draw the inflated receptacle toward the first organ such that the inflated receptacle retains the second organ in sealing contact with the first organ while maintaining the alignment between the first and second openings to create an anastomosis between the first and second organs.
Abstract:
A surgical instrument for creating an anastomosis between two organs. In various embodiments, the instrument may include a hollow outer sleeve for creating a tool-receiving passage between a natural orifice in the patient and the surgical site. The tool receiving passage may be used to operably accommodate various surgical instruments such as an endoscope, a hole-forming instrument, and suction and aeration tubes for assisting in the formation of the anastomosis. The hollow outer sleeve may further be used to position a hollow anastomosis sleeve segment within two aligned holes in the organs. The anastomosis sleeve segment supports an inflatable distal receptacle that is inflated within one of the organs and a proximal inflatable receptacle that is inflated in the other organ to retain the anastomosis sleeve segment in position. Thereafter, the hollow outer sleeve is withdrawn from the patient leaving the hollow anastomosis sleeve segment in position between the two organs.
Abstract:
Disclosed is an instrument for use in a procedure to effect anastomosis of a patient's bladder and urethra following a prostatectomy having a tube assembly, and an end effector assembly operably supported by the tube assembly. The end effector assembly includes a positioner assembly, an anchor driver assembly and an anchor for insertion into and through the patient's bladder wall and pelvic floor and an anchor guide associated therewith. The end effector also includes a harness adapted to receive a balloon portion of a balloon catheter assembly.
Abstract:
An equipment to approximate tissue portions, which are intended to form an anastomosis comprises a guide means suitable for passing through a first tissue portion (12) and a second tissue portion (14) to be connected by anastomosis. This equipment further comprises an anastomotic device (10) to approximate the first tissue portion (12) and the second tissue portion (14) to be connected by anastomosis. The guide means consists of at least two guide wires (A, B), suitable for passing through the tissue portions to be connected, to receive and drag at least said anastomotic device (10) to approximate the first tissue portion (12) and the second tissue portion (14) to be connected by anastomosis. The guide wires (A, B) are located side by side to each other and are suitable for forming a loop which passes through the tissue portions to be connected.
Abstract:
A ring or rings adapted for endoluminal placement within the stomach, other hollow organ or vessel, and a method for deploying the rings is described. The rings create a small pouch with a reinforced stoma in the stomach for the treatment and control of obesity. An endoluminal suturing device for deploying a circumferential line of interrupted mattress suture bites is inserted into the patient's stomach via the patient's mouth. The distal gastric ring is preloaded on the distal end of the suturing device and is incorporated with suture loops from the double-armed sutures contained within the device. The suturing device can have an expandable area at its distal end that can expand its diameter to between approximately 10mm and 150mm. The circumference of this expanded area has a suction opening that is used to draw in tissue when a vacuum is applied to the device. Flexible cannulas containing . long flexible suture needles are positioned radially around the circumference of the suction opening. The long needles are are adapted to be advanced through the drawn in tissue incorporating their attached suture material. The expandable area of the device is collapsed, and the device is withdrawn from the patient. With the distal ring anchoring the sutures beneath the incorporated tissue folds, a column of sutures exits the device's suction port as the device is withdrawn. A second, proximal ring is then incorporated with the sutures and may then be endoscopically lowered into the patient's stomach and positioned proximal to the distal ring. The sutures are endoscopically secured and cut, thereby fixing the two rings together with tissue incorporated between them.

Abstract:
An assisted anastomosis apparatus and a method thereby for reconnecting the urethral stump to the neck of the bladder after removal of the prostate during a prostatectomy, comprising two suture units, namely a urethral stump suturing unit (1a) and a bladder suturing unit (1b), at least a section of said urethral stump suturing unit (1a) has suitable dimensions to be introduced into a bladder neck and at least a section of said bladder suturing unit (1b) has suitable dimensions to be introduced into a urethral stump; such that each needle pulls the suture leading from its equivalent position on the urethral stump through the wall of the bladder neck.
Abstract:
An anastomotic device, particularly a positioning device (24) extending along a longitudinal axis (30) comprises a first component, or proximal component (26) and a second component, or distal component (28). The proximal and distal components are suitable to lock an elastic ring (52) in a deformed configuration therebetween. The proximal component (26)has a substantially cylindrical outer structure with a cavity (32) for receiving a proximal end (52a) of the elastic ring (52). The distal component (28) comprises a head (42) and a stem (44) developing along the longitudinal axis (30). The head (42) has a cone or truncated-cone shape.
Abstract:
An anastomotic device for use in the joining of a first tubular structure and a second tubular structure is provided. The anastomotic device includes a cylindrical sleeve configured and dimensioned for placement at least partially within the first tubular structure, the cylindrical sleeve defining a bore therethrough; an inverting member configured and dimensioned for placement at least partially within the second tubular structure, the inverting member defining a bore therethrough which is configured and dimensioned to selectively receive the cylindrical sleeve therein; and a constricting member selectively positionable on the inverting member and movable onto the cylindrical sleeve when the cylindrical sleeve is at least partially positioned within the bore of the inverting member.
Abstract:
The tissue holding device of the present invention is composed of at least two, substantially hollow, adjustable suction clamps (32, 34), configured for one-sided clamping, that detachably adhere to the surface of the tissue by way of at least one suction opening (8) in each suction clamp. The suction clamps are mechanically associated by a displacement mechanism (12).
