Low residual bladder catheter
First Claim
1. A bladder catheter, comprising:
- an elongate tubular body having a proximal portion with a proximal end, a distal portion with a distal end, a retaining portion disposed between the proximal portion and the distal portion, a drainage lumen therethrough, and a support within the tubular body;
wherein the retaining portion has a retaining mechanism affixed to the tubular body;
wherein the proximal portion has a proximal port;
wherein the distal portion has an axial length;
wherein the distal portion has at least one opening therein;
wherein the drainage lumen extends from the proximal port in the proximal end to the at least one opening in the distal portion; and
wherein the support substantially prevents closure of the drainage lumen from axial bending of the distal portion.

Abstract
A bladder catheter comprising an elongate tubular body having a proximal portion with a proximal end, a distal portion, preferably between at least about 8 cm and 30 cm, with a distal end and a retaining portion with retaining mechanism disposed between the proximal portion and the distal portion. The tubular body of the bladder catheter further comprises a drainage lumen extending therethrough from a drainage port in the proximal end to at least one opening in the distal portion. The distal end of the catheter preferably comprises a weight. A method of continuously draining urine in a patient, comprising the steps of inserting a bladder catheter according to the present invention into the patient'"'"'s urethra until the retaining mechanism and distal portion reside within the patient'"'"'s bladder, actuating the retaining mechanism of the catheter, allowing the distal end of the catheter to fall into the dependent portion and, thereby, draining urine in the dependent portion of the bladder.
