摘要:
A catheter (250, 272) is provided for uniform distribution of fluid medicationwithin an anatomical region. One embodiment of the catheter (272) is comprisedof an elongated, proximal tube (282) defining a lumen (283) and an elongated,distal tube (280) having a closed end (284). The distal tube (280) isconstructed from a bio-absorbable material and also defines a lumen (281),which communicates with the lumen (283) of the proximal tube (282). Anotherembodiment of the catheter (250) is comprised of an elongate tubular catheterbody (254) defining a lumen (268). A distal end (262) of the lumen is closedand a portion of the catheter body (254) includes a plurality of openings(266) thereby defining an infusion section of the catheter (250). A tubularsheath (252) is constructed from a porous material and is positioned over theinfusion section. The tubular sheath (252) extends at least a length of theinfusion section. The tubular sheath (252) and the catheter body (254) areconfigured such that fluid within the lumen (268) must pass through thetubular sheath (252) to exit the catheter (250).
