Device, system and method for intersititial transvascular intervention
First Claim
1. A method for effecting revascularization of a portion of the cardiovascular system of a mammalian patient, said method comprising the steps of:
- (A). providing a pliable catheter which has a tissue penetrating element passable therefrom;
(B). inserting said catheter into the vasculature and advancing said catheter to a first location within the cardiovascular system of the patient;
(C). passing the tissue penetrating element from the catheter to form a first interstitial passageway from said first location to a second location within the cardiovascular system of the patient, and through any tissue located between said first and second locations, said interstitial passageway thereafter functioning as a conduit to carry blood, in at least one direction, between said first and second locations.(D). placing the catheter at a third location within the cardiovascular system of the patient; and
,(E). passing the tissue penetrating element from the catheter, a second time, to form a second interstitial passageway which extends from the third location within the cardiovascular system of the patient to a forth location within the cardiovascular system of the patient, and through any tissue located between said third and fourth locations, said second interstitial passageway thereafter functioning as a conduit to carry blood, in at least one direction, between said third and forth locations.

Abstract
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.

21. A method for effecting revascularization of the heart of a mammalian patient, said method comprising the steps of:
-
(A). transluminally forming a first opening in an arterial blood-containing portion of the patient'"'"'s cardiovascular system; (B). transluminally forming a second opening in a venous blood-containing portion of the patient'"'"'s coronary circulation; and
,(C). causing blood to flow between said first and second openings such that arterial blood which passes through said second opening will subsequently flow through at least one coronary vein, in a direction opposite normal venous flow, to thereby perfuse the myocardium. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

51. A method for effecting revascularization of a portion of the cardiovascular system of a mammalian patient, said method comprising the steps of:
-
(A). providing a pliable catheter which has a tissue penetrating element passable therefrom and an orientation apparatus; (B). inserting said catheter into the vasculature and advancing said catheter to a first location within the cardiovascular system of the patient; and
,(C). utilizing said orientation apparatus to orient the catheter such that the tissue penetrating element is aimed at the second location, (D). passing the tissue penetrating element from the catheter to form an interstitial passageway from an first location to the second location within the cardiovascular system of the patient and through any tissue located between said first and second locations, said interstitial passageway thereafter functioning as a conduit to carry blood, in at least one direction, between said first and second locations. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73)

74. A method for rerouting bloodflow in coronary or peripheral blood vessels of a mammalian body, without transecting any of said blood vessels, said method comprising the steps of:
-
(A) forming a first opening in the wall of a blood vessel; (B) forming a second opening in the wall of a blood vessel; and
,(C) forming an interstitial passageway through any tissue located between said first and second openings such that blood will flow out of said first opening and into said second opening. - View Dependent Claims (75, 76, 77, 78, 79, 80, 81, 82, 83, 84)
