Apparatus and methods for positioning and securing anchors are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism either within the anchor itself of positioned proximally of the anchor may allow for the uni-directional translation while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This uni-directional anchor locking mechanism facilitates the cinching of the tissue plication between the anchors and it may be utilized in one or several anchors in cinching a tissue fold.

An intravascular thermography device comprising an elongate catheter having a distal guidewire port, a proximal guidewire port at a location closer to the distal end of the catheter than the proximal end, and a guidewire lumen. An expansion frame is attached to the catheter. The expansion frame is operable to expand, and has at least one temperature sensor. A capture sheath is slideably disposed about the expansion frame and operable from the proximal end of the catheter to release the expansion frame when the capture sheath is removed from the expansion frame. The capture sheath has a passage in a distal region of the capture sheath, the passage being shaped to align with the proximal guidewire port of the catheter. A registry mechanism is provided to maintain circumferential alignment between the proximal guidewire port and the passage in the distal region of the capture sheath. Methods of use are also disclosed.

An intravascular thermography device comprising an elongate catheter having a proximal end, a distal end, a distal guidewire port in a distal region of the catheter, a proximal guidewire port at a location closer to the distal end of the catheter than the proximal end, and a lumen is described. The lumen extends between the proximal guidewire port and the distal guidewire port and is adapted to receive a guidewire. An expansion frame is attached to the catheter at a location distal to the proximal guidewire port. The expansion frame is operable between a contracted condition and an expanded condition, and has at least one temperature sensor. Methods of use are also described.

600/549000

A thermography system that can be used in the vasculature of a patient, or elsewhere, with a catheter and an instrument configured to graphically display thermography data from the catheter. Sensors on the catheter may measure blood temperature, wall temperature of a body vessel or both as well as differences between blood temperature and wall temperature. Temperature differences from different locations of a patient's body vessel can be measured contemporaneously, compared and displayed on the graphical display which may be a graphic user interface in some embodiments.

A flexible thermography catheter which includes an elongated body having a proximal end, a distal end, and a distal section, an expandable body comprising at least one independently movable support arm located at the distal section of the elongated body, at least one support arm retainer positioned on the distal section of the elongated body, and at least one sensor positioned on at least one of the distal section, the expandable body, and the at least one support arm. The at least one support arm retainer is configured to independently secure at least one section of the at least one support arm to the distal section of the elongated body in independently movable relation to each of the at least one support arm and the elongated body.

Methods and apparatus for grasping a suture and cinching and/or locking a tissue anchor are provided. In one variation, a tube is provided having a lumen and a resilient member that obstructs the lumen. A grasper may be advanced coaxially through the lumen, such that it reversibly displaces the resilient member and extends beyond the lumen's outlet to engage suture of the tissue anchor. With suture engaged, the grasper may be withdrawn within the tube, such that the resilient member again obstructs the lumen of the tube. Continued retraction of the grasper relative to the tube and anchor may act to cinch the anchor via interaction between a cinching/locking mechanism of the anchor and the obstructing resilient member. In an alternative variation, a snare device is provided comprising a resilient wire loop that coacts with an element of the snare device or of the tissue anchor for grasping and cinching the tissue anchor.
