Abstract:
1. A method for delivering an extrudable material within a body of a mammal, the method comprising the steps of: (a) providing a delivery catheter, the delivery catheter comprising: (1) 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; and (2) 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 (ii) to push at least some of the first and second materials from the distal section and out of the first distal opening; and (b) extruding a fibrous material out of the distal section and into the body of a mammal, wherein step (b) comprises i. delivering the first material comprising a crosslinking agent to the distal section through the first lumen; ii. delivering the second material comprising a crosslinkable polymer to the distal section through the second lumen, thereby forming a fibrous material in the distal section; and iii. pushing the fibrous material out of the distal section by sliding distally and longitudinally the distal valve into the distal section.
