Abstract
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.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
103 words
A catheter device for delivering a substance to a target site located outside of the lumen of a blood vessel; a catheter that is advanceable into the blood vessel lumen; a penetrator that is advanceable from the catheter; a lumen extending through the penetrator; and, trajectory indicating apparatus for indicating the trajectory on which the penetrator will advance relative to the location of the target site, thereby enabling an operator to place the catheter in such position and rotational orientation within the blood vessel lumen that the penetrator will advance from the catheter, out of the blood vessel lumen to the target site.
