Catheters and related devices for forming passageways between blood vessels or other anatomical structures
First Claim
1. A catheter device, comprising:
- an elongate flexible catheter having a distal portion insertable into a blood vessel of a human subject;
a tissue penetrating member configured to extend in a first direction from the distal portion of the catheter;
a balloon exit port in the distal portion of the catheter at a location diametrically opposite a location from which the tissue penetrating member extends;
a balloon which, when inflated, protrudes out of the balloon exit port in a second direction opposite the first direction; and
a lumen extending through the catheter and useable for inflation and deflation of the balloon.

Abstract
The inventions described in this patent application include i) a torqueable introducer sheath which is useable in conjunction with a transvascular passageway forming catheter to effect precise rotational control of the catheter; ii) an anchorable guide catheter which is useable in conjunction with an intravascular imaging catheter and a transvascular passageway-forming catheter to effect precise positioning and aiming of the passageway-forming catheter; iii) a passageway forming catheter having a torqueable proximal portion to facilitate precise rotational positioning of the distal portion of the catheter; iv) a deflectable-tipped passageway forming catheter, v) various markers and other apparatus useable in conjunction with any of the passageway-forming catheters to facilitate precise positioning and aiming of the catheter, and vi) an apparatus which may be formed within a catheter to prevent a member, apparatus of flow of material from being inadvertently advanced through a lumen of the catheter.
