Abstract: An endostapler delivery system includes a biasing mechanism to offset or counter forces generated by a stapling device and therefore prevent the stapling device from moving during the firing of the staple. The delivery system includes a catheter having at least one lumen extending there through for receiving the stapling device. The biasing mechanism is an expandable biasing cage having a dome or semi-circular expanded shape provided at the distal portion of the catheter. When expanded, the biasing cage does not block or occlude a vessel, thereby allowing blood flow to continue during the stapling procedure. The biasing cage may include a plurality of ribbons or strands that extend generally parallel to the blood flow when expanded in situ, a mesh or braided structure, or a plurality of ribbons or strands that extend generally parallel to the blood flow when expanded in situ and a mesh or braided structure placed over the plurality of ribbons.

Abstract: According to the present invention, a catheter having at least one multi-purpose lumen formed through the catheter terminates proximal a relatively complex-shaped distal portion thereof. In one form of this embodiment, the relatively complex-shaped distal portion comprises a looped portion having diagnostic- and/or ablation-type electrodes coupled thereto and an elongated diameter-adjusting member coupled proximal the distal end of the looped portion. The multi-purpose lumen may be used to alternately accommodate a variety of dedicated materials; such as, (i) a guide wire for initial deployment or later repositioning of the catheter, (ii) a volume or flow of a contrast media and the like, (iii) a deployable hollow needle or tube and the like used to biopsy adjacent tissue or dispense a therapeutic agent into a volume of tissue, and (iv) a cooling fluid, such as saline solution and the like dispensed at least during therapeutic tissue ablation procedures.

Abstract: A tissue stabilizer including an elongated arm, a collet, and a head-link assembly. The collet is disposed at a distal end of the arm. The head-link assembly includes a tube and a spreading mechanism. The tube forms an intermediate section and opposing arms each terminating at a tip. The spreading mechanism can adjust a lateral distance between the tips, and includes first and second articulating members each having a leg and a collet interface body. The first member further includes a female hinge feature, whereas the second member includes a male hinge feature differing from the female hinge feature. The legs of are mounted to discrete regions of the tube, and the male hinge feature is pivotably coupled to the female hinge feature. Automatic spreading of a lateral distance between the tips occurs in response to a compressive force applied to the collet interface bodies.
