Abstract
A system of catheter devices and methods for forming channels or passageways between a luminal anatomical structure (e.g., a blood vessel) and 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.
Claims2
A tissue penetrating catheter device useable to penetrate outwardly from the lumen of a blood vessel in which the catheter device is positioned, through the wall of that blood vessel, and to a target location, said device comprising:
- i) a flexible catheter body which is insertable into the vein, said catheter body having a side•wall, a proximal end, a distal end and an outlet opening formed in the side wall thereof;
- ii) an first lumen through which a separate imaging catheter may be inserted;
- iii) a second lumen which extends through said outlet opening;
- iv) a tissue penetrating member disposed within said second lumen and advanceable out of said outlet opening;
- and,
- v) an orientation structure positioned on the catheter body, said orientation structure having a) an imaging catheter-receiving space formed therein in alignment with said first lumen and b) at least one marker member located on one side of the imaging catheter receiving space, said at least one marker being positioned and constructed to create on an image display received from an imaging catheter positioned within the imaging catheter-receiving space, an indication of the path that will be followed by the tissue penetrating member as the tissue penetrating member is advanced from the catheter body.
