Abstract: The inventions described in this patent application include i) a torqueable introducer sheath which is useable in conjunction with a transvascular passageway forming catheter to effect precise rotational control of the catheter; ii) an anchorable guide catheter which is useable in conjunction with an intravascular imaging catheter and a transvascular passageway-forming catheter to effect precise positioning and aiming of the passageway-forming catheter; iii) a passageway forming catheter having a torqueable proximal portion to facilitate precise rotational positioning of the distal portion of the catheter; iv) a deflectable-tipped passageway forming catheter, v) various markers and other apparatus useable in conjunction with any of the passageway-forming catheters to facilitate precise positioning and aiming of the catheter, and vi) an apparatus which may be formed within a catheter to prevent a member, apparatus of flow of material from being inadvertently advanced through a lumen of the catheter.

Abstract: Methods and apparatus for passing attachment apparatus (e.g., connector devices, staples, etc.) or connector material (e.g., suture thread, wire, cord, filament, monofilament, etc.) into or through the wall of a luminal anatomical structure (e.g., a blood vessel or other anatomical conduit) for the purpose of; i) closing the lumen of the anatomical structure, ii) forming an anastomotic junction between separate anatomical structures (or between approximated segments of the same anatomical structure), and/or iii) attaching an article (e.g., an endoluminal, extraluminal or transluminal graft) or other apparatus to the wall of the anatomical structure.

Abstract: Methods, devices, and systems for a) revascularization and/or b) performing other medical procedures at vascular or non-vascular intracorporeal locations within a mammalian body. The methods generally comprise the formation of at least one extravascular passageway from a blood vessel to a vascular or non-vascular target location. In the revascularization methods the extravascular passageway is utilized for blood flow. In the medical procedure methods the extravascular passageway is utilized as a conduit for accessing or performing procedures at the vascular or non-vascular target location. Also disclosed are catheter devices and systems which are useable to form the extravascular passageways of the invention, as well as apparatus for modifying, maintaining and/or closing such extravascular passageways.
