Catheter for uniform delivery of medication
View Patent ↗A catheter is provided for uniform distribution of fluid medication within an anatomical region. One embodiment of the catheter is compromised 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.
1. 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 and a distal end tip which defines the distal end of the tubular member, said distal portion and said distal end tip comprising a bio-absorbable material wherein the distal portion and the distal end tip remain in the patient and are absorbed, 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.
2. The method of claim 1 , additionally comprising utilizing bio-absorbable sutures to secure said distal portion in a desired position within said patient.
3. The method of claim 1 , wherein said positioning of said tubular member comprises positioning said joint within between about 0.1 and 4 inches of said incision.
4. The method of claim 1 , wherein said positioning of said tubular member comprises positioning said joint within between about 0.1 and 0.5 inches of said incision.
5. The method of claim 3 , wherein said bio-absorbable material is configured to dissolve sufficiently within 5-7 days after said inserting within said patient so as to permit release of said proximal portion from said distal portion, the method additionally comprising removing said proximal portion from said patient without opening said incision or creating a new incision.
