Abstract
A delivery catheter for delivering material(s) into the body of a mammal can include a first elongated member and a second elongated member. At least a portion of the second elongated member can be slidably disposed within a lumen of the first elongated member. The delivery catheter can mix two materials and then introduce the mixed materials into the body of a mammal.
Claims22
A delivery catheter, comprising:
- (a) a first elongated member defining a first distal opening and a first lumen extending within the first elongated member, the first elongated member for delivering a first material through the first lumen and into a distal section of the first lumen near the first distal opening;
- (b) a second elongated member comprising a distal valve and a second lumen extending within the second elongated member, the second elongated member for delivering a second material through the second lumen and the distal valve, at least a portion of the second elongated member being slidably disposed within at least a portion of the first lumen such that the distal valve is selectively slidable
- (i) to allow delivery of the second material through the second lumen and the distal valve and into the distal section, and
- (iv) to push at least some of the first and second materials from the distal section and out of the first distal opening;
- (c) a first injector adapted for connection to the first elongated member for injecting the first material into the first lumen;
- and
- (d) a second injector adapted for connection to the second elongated member for injecting the second material into the second lumen.

- and
- (c) an access joint between a first proximal joint and the first distal opening, the access joint allowing insertion of the at least a portion of the second elongated member into the at least a portion of the first lumen.
