The invention relates to a device and related method for sealing and / or dissecting body tissue using a reverse action instrument. The devices and methods described permit laparoscopic or natural body orifice access to an anatomical space and facilitate sealing portions of tissue together, dissecting tissue or combinations thereof. A surgical instrument for sealing and dissecting body tissue is described having distal and proximal ends with an elongated body. The body includes a jaw member positioned at the distal end that is defined by a stationary arm and a pivotable arm. A moveable closure sleeve is disposed at least partially about the body and the closure sleeve is configured such that coaxial movement of the sleeve along the longitudinal axis of the body causes the jaw member to open or close.

A medical apparatus positionable in a cavity of a bodily organ (e.g., a heart) may constrict a bodily orifice (e.g., a mitral valve). The medical apparatus may include tissue anchors that are implanted in the annulus of the orifice. The tissue anchors may be guided into position by an intravascularly or percutaneously deployed anchor guiding frame. Constriction of the orifice may be accomplished by cinching a flexible cable attached to implanted tissue anchors. The medical device may be used to approximate the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve in order to move the posterior leaflet anteriorly and the anterior leaflet posteriorly and thereby improve leaflet coaptation and eliminate mitral regurgitation.

A device, kit and method may employ an implantable device (e.g., annuloplasty implant) and a tool to implant such. The implantable device is positionable in a cavity of a bodily organ (e.g., a heart) and operable to constrict a bodily orifice (e.g., a mitral valve). Tissue anchors are guided into precise position by an intravascularly deployed anchor guide frame and embedded in an annulus. Constriction of the orifice may be accomplished via a variety of structures, for example by cinching a flexible cable or anchored annuloplasty ring, the cable or ring attached to the tissue anchors. The annuloplasty ring may be delivered in a generally elongated configuration, and implanted in an anchored generally arch, arcuate or annular configuration. Such may move a posterior leaflet anteriorly and an anterior leaflet posteriorly, improving leaflet coaptation to eliminate mitral regurgitation.

A probe that facilitates the creation of lesions in bodily tissue. The probe includes a relatively short shaft and an inflatable therapeutic element.

A device, kit and method may include or employ an implantable device (e.g., annuloplasty implant) and a plurality of tissue anchors. The implantable device is positionable in a cavity of a bodily organ (e.g., a heart) and operable to constrict a bodily orifice (e.g., a mitral valve). Each of the tissue anchors may be guided into precise position by an intravascularly or percutaneously techniques. Constriction of the orifice may be accomplished via a variety of structures, for example an articulated annuloplasty ring, the ring attached to the tissue anchors. The annuloplasty ring may be delivered in an unanchored, generally elongated configuration, and implanted in an anchored generally arched, arcuate or annular configuration. Such may approximate the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve, to move the posterior leaflet anteriorly and the anterior leaflet posteriorly, thereby improving leaflet coaptation to reduce mitral regurgitation.

Surgical method and apparatus for resectioning tissue, preferably lumenal tissue, with a remaining portion of an organ being anastomized with staples or other fastening means, 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.

A probe that may be used to create circumferential lesions in body tissue and, in some implementations, may also be used to perform mapping functions. The probe includes a collapsible / expandable structure that supports electrodes or other operative elements against the body tissue.

Anastomotic leak tester for testing for leaks in a gastrointestinal anastomosis in a patient including an air introduction system adapted to be inserted into the patient's gastrointestinal tract through a natural body orifice of the patient and enabling air flow therethrough into the gastrointestinal tract and a regulating mechanism arranged in connection with the air introduction system for regulating air pressure in the patient's gastrointestinal tract. The regulating mechanism may include a pressure relief valve having an inlet communicating with an interior space of the air introduction system communicating with the patient's gastrointestinal tract and which allows air to be released from the patient's gastrointestinal tract when air pressure in the patient's gastrointestinal tract exceeds a predetermined pressure. The pressure relief valve may generate an audible indication when air pressure in the patient's gastrointestinal tract exceeds the predetermined pressure.

A method for inserting an instrument through a natural orifice. The instrument has a low profile orientation and a deployed orientation which is larger than the size of the natural orifice through which it is to be inserted. The method is achieved by coupling the instrument to an endoscope and placing the instrument in its low profile orientation, inserting the endoscope and the instrument through a natural orifice to a target position within a body while the instrument is in its low profile orientation, actuating the instrument to it is deployed orientation, and returning the instrument to its low profile orientation and withdrawing the instrument from the body through the natural orifice.
