摘要:
This invention is methods and apparatus for direct coronary revascularization wherein a transmyocardial passageway (10) is formed between a chamber of the heart (LV) and a coronary blood vessel (CBV) to permit blood to flow therebetween. In some embodiments, the transmyocardial passageway (10) is formed between a chamber of the heart (LV) and a coronary vein (CV). The invention includes unstent transmyocardial passageways (10), as well as transmyocardial passageways (10) wherein protrusive stent devices (90) extend from the transmyocardial passageway (10) into an adjacent coronary vessel (CBV) or chamber of the heart (LV). The apparatus of the present invention includes protrusive stent devices (90) for stent of transmyocardial passageways (10), intraluminal valve devices (40) for valving of transmyocardial passageways (10), intra-cardiac valve devices (80) for valving of transmyocardial passageways (10), endogenous tissue valves (50) for valving of transmyocardial passageways (10), and ancillary apparatus for use in conjunction therewith.
摘要:
Method and apparatus for utilizing the vascular system as a conduit to reach other vascular and extravascular locations within the body. Included are methods for revascularization wherein the extravascular passageways are formed to permit blood flow between vascular locations. Also included are methods for performing transvascular interstitial surgery (TVIS) wherein extravascular passageways are formed from a blood vessel to another vascular or non-vascular intracorporeal location. Also disclosed are devices usable for forming extravascular passageways in accordance with the invention, or for modifying, valving, maintaining or closing such passageways.
摘要:
This invention is methods, devices, and systems for re-vascularization, and/or performing other medical procedures at a vascular or non-vascular intra-corporeal 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 re-vascularization 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 (100, 103) and systems (138) which are usable to form the extravascular passageways of the invention, as well as apparatus for modifying, maintaining and/or closing such extravascular passageways.
摘要:
This invention is methods and apparatus for connecting two anatomical passageways, such as blood vessels, in side-to-side fashion. Openings are formed in the sidewalls of the passageways, and a connector apparatus (10) of the present invention is implanted within such openings, and extends between the passageways or blood vessels (BV1, BV2) so as to connect the passageways or blood vessels (BV1, BV2) such that the openings are held in direct alignment with one another, thereby allowing body fluids to pass from one passageway into the other.
摘要:
This invention is devices, systems and methods for trans-vascular interstitial interventions, including trans-vascular, catheter based vascular bypass, transmyocardial re-vascularization, bypass grafting of blood vessels, and interstitial surgical/interventional procedures wherein a catheter is advanced trans-lumenal through the vasculature (2) to a desired location (OB) and an operative instrument (5) is passed through the wall (2) of a blood vessel (2) and to a target location (3) (e.g., another blood vessel, an organ, a tumor, another anatomical structure) such that one or more operative devices may be advanced to the target location to perform the desired operative or interventional procedure.
