摘要： A catheter device (11) that is useable to penetrate from a blood vessel in which the catheter device (11) is positioned to a target location, comprises a flexible catheter advanced into the blood vessel, a tissue penetrator (85) which is useable to penetrate from the blood vessel to the target location when properly aimed. Further said catheter includes an imaging transducer (81) fixedly mounted on or within the catheter body (13) to provide an imaging signal from which an image of the target location can be obtained. The catheter device (11) may include an imaged marker (101) on the catheter to form on the image obtainable from the imaging signal a penetrator path indication that indicates the path that will be followed by the tissue penetrator when the tissue penetrator (85) exits from the catheter (11). Alternatively, or in addition thereto, the imaging transducer (81) may comprise a plurality of imaging elements.

摘要： Methods and apparatus for delivery of substances or apparatus to target sites. A vessel wall penetrating catheter (11) is inserted into the vasculature, positioned and oriented with a blood vessel near the target extravascular site and a penetrator (85) is advanced from the catheter so as to penetrate outwardly through the wall of the blood vessel in the direction of the target site. Thereafter, a delivery catheter (12) is passed through a lumen of the penetrator to the target site. A desired substance or apparatus is then delivered to or obtained from the target site.

摘要： A system of catheter devices (10), and methods for forming channels or passageways between a luminal anatomical structure (e.g., a blood vessel), a target location (e.g., another blood vessel, an organ, a mass of tissue, etc.) for the purpose of rerouting blood flow or for delivering a substance or instrument, etc. to the target location.
