Abstract
A catheter is provided for uniform distribution of fluid medication within an anatomical region. One embodiment of the catheter is comprised of an elongated, proximal tube defining a lumen and an elongated, distal tube having a closed end. The distal tube is constructed from a bio-absorbable material and also defines a lumen, which communicates with the lumen of the proximal tube. In one embodiment, at least a portion of the distal tube defines a porous side wall that permits fluid within the lumen to pass through the portion of the distal tube. In another embodiment, the proximal tube and the distal tube overlap one another and are secured to one another at the overlapping surfaces.
Claims17
A catheter for delivering a fluid to an anatomical region, comprising:
- an elongated, proximal tube defining a lumen;
- an elongated, distal tube constructed from a bio-absorbable material, said distal tube defining a lumen communicating with said lumen of said proximal tube, at least a portion of said distal tube permitting communication of said fluid from within said lumen to external of said distal tube thereby defining an infusion section of said catheter;
- wherein a proximal end portion of said distal tube and a distal end portion of said proximal tube overlap, said proximal end portion of said distal tube being bonded to said distal end portion of said proximal tube with a bio-compatible adhesive to create a substantially fluid-tight joint therebetween, a length of an overlapping portion of said proximal tube and said distal tube being at least about 0.02 inches.
A catheter for delivering a fluid to an anatomical region, comprising:
- an elongated, proximal tube defining a lumen;
- an elongated, distal tube having a closed end, said distal tube being constructed from a bio-absorbable material and defining a lumen communicating with said lumen of said proximal tube;
- wherein at least a portion of said distal tube defines a porous side wall permitting fluid within said lumen to pass through said portion of said distal tube.
A method for delivering a fluid throughout an anatomical region of a patient, comprising:
- inserting an elongate, tubular member into an incision of said patient, said tubular member having a proximal portion attached to a distal portion at a joint, said distal portion comprising a bio-absorbable material, at least a portion of a side wall of said distal portion defining a porous membrane adapted to permit fluid within said tubular member to pass through said side wall;
- positioning said tubular member such that said joint is within said patient;
- closing said incision;
- and
- introducing fluid into an open proximal end of said tubular member.
