Internal catheter
First Claim
1. A catheter for insertion into a patient'"'"'s urethra, comprising:
- (a) first and second tubular members having such a diameter for enabling drainage of physiological fluids therethrough, each of said first and second tubular members having a wall of a specific thickness, said first and second tubular members being interconnected by a connecting tube of substantially smaller diameter; and
(b) a first inflatable balloon attached to said second tubular member, said first inflatable balloon being in fluid communication with said connecting tube, and thereby inflatable via said connecting tube;
wherein,(i) said first inflatable balloon serves for insertion into the patient'"'"'s urinary bladder, said balloon is positioned on said second tubular member and is inflatable to dimensions and shape, such that by inserting said first inflatable balloon to the patient'"'"'s urinary bladder, inflating said first inflatable balloon, and pulling the catheter so as to position said balloon against the bladder, said second tubular member engages substantially the entire length of the patient'"'"'s prosthetic urethra and extends into the bladder; and
(ii) a portion of said connecting tube interconnecting said first and second tubular members has a length, such that when said second tubular member is positioned to engage substantially the entire length of the patient'"'"'s prosthetic urethra and to extend into the bladder, said connecting tube engages substantially the entire length of the patient'"'"'s sphincter, such that said first tubular member is located in the patient'"'"'s urethra distally to the patient'"'"'s sphincter, so as to allow drainage of fluid from the patient'"'"'s bladder, through said second tubular member, through said patient'"'"'s sphincter, through said first tubular member and through the patient'"'"'s urethra out of the patient'"'"'s body.

Abstract
A catheter for insertion into a patient'"'"'s urethra is provided, comprising: (a) first and second tubular members having such a diameter for enabling drainage of physiological fluids therethrough, the first and second tubular members being interconnected by means of a connecting tube of substantially smaller diameter; (b) an inflatable balloon attached to the second tubular member, the inflatable balloon being in fluid communication with the connecting tube. The inflatable balloon is inserted to the patient'"'"'s urinary bladder so as to locate the second tubular member substantially within the patient'"'"'s prostatic urethra such that the connecting tube is held by the patient'"'"'s sphincter. Further according to the present invention there is provided a guiding element for insertion through the catheter, including: (a) a substantially elongated tubular member having a hollow, the elongated tubular member having a closed end for insertion through the patient'"'"'s urethra and an open end for connection to an external inflating element; (b) an inflatable balloon attached to the elongated tubular member, the inflatable balloon being in fluid communication with the hollow of the tubular element, the inflatable balloon for inflation against the catheter so as to effectively fix the guiding element to the catheter.
