Abstract
Abstract A bladder catheter for males including an elongated flexible core element having first and second end portions and an outer surface provided with one or more grooves extending along said element, means at the first end portion of said element for being received and retained within the bladder of a subject to be treated, and a flexible tubular member with an opening therethrough for being received about said core element, whereby after said element with its member about it are inserted into the urethra of the subject with the first end of the element received and retained within the bladder, the member is partially withdrawn from about the element to an extent allowing the urethra to be flushed by the draining urine while still remaining in position over the second end portion of the element to receive the urine into the member for external disposal.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A bladDer catheter for males including an elongated flexible core element having first and second end portions and an outer surface provided with one or more grooves extending along said core element, means at the first end portion of said core element for being received and retained within the bladder of a subject to be treated, and a flexible tubular member with an opening therethrough being slidably received about said core element, whereby after said element with its tubular member about it are inserted into the urethra of the subject with the first end portion of the core element received and retained within the bladder, the tubular member is partially withdrawn from about the core element to an extent allowing the urethra to be flushed by the draining urine while still remaining in position over the second end portion of the core element to receive the urine into the tubular member for external disposal.
Claim 2
Dependent Claim
154 words
A bladDer catheter for males including an elongated flexible core element having first and second end portions and an outer surface provided with one or more grooves extending along said core element, means at the first end portion of said core element for being received and retained within the bladder of a subject to be treated, and a flexible tubular member with an opening therethrough being slidably received about said core element, whereby after said element with its tubular member about it are inserted into the urethra of the subject with the first end portion of the core element received and retained within the bladder, the tubular member is partially withdrawn from about the core element to an extent allowing the urethra to be flushed by the draining urine while still remaining in position over the second end portion of the core element to receive the urine into the tubular member for external disposal.
Claim 3
Dependent Claim
23 words
The catheter of claim 1 in which the outer surface of said core element is provided with a plurality of longitudinally extending grooves.
Claim 4
Dependent Claim
20 words
The catheter of claim 1 in which the outer surface of said core element is provided with a spiral groove.
Claim 5
Dependent Claim
54 words
The catheter of claim 1 in which the retaining means at the first end portion of said core element is a resilient inflatable bulb, said core element having a valve at the second end portion and a central opening extending between said bulb and valve, whereby said bulb may be controllably inflated and deflated.
Claim 6
Dependent Claim
58 words
The catheter of claim 1 in which the retaining means at the first end portion of said core element is a preformed resilient collapsible bulb whereby said bulb is deformable to reduced size for insertion through the urethra and upon entering the bladder resumes its preformed configuration for retaining same therein and deforms to reduced size for removal.
Claim 7
Dependent Claim
34 words
The catheter of claim 5 in which said bulb is hollow having a cavity therein, and said core element has a central opening communicating with the cavity of said bulb and venting same externally.
Claim 8
Dependent Claim
29 words
The catheter of claim 1 in which an end of said tubular member has an enlarged outer collar for contact with the urethra for minimizing seepage of urine thereby.
Claim 9
Dependent Claim
73 words
The catheter of claim 1 in which said core element is substantially circular in cross section and comprising a first section including the first portion of said core element and a second section including the second end portion joined at a point intermediate said end portions, said first section having a cross section greater than that of said second section, said tubular member being received about the second section of said core element.
Claim 10
Dependent Claim
61 words
The catheter of claim 8 in which the outer diameter of said tubular member is substantially equal to the outer diameter of the first section of said core element, and said tubular member is received about the second section of said core element with an end of said tubular member in abutting relationship to said first section of said core element.
Claim 11
Dependent Claim
32 words
The catheter of claim 1 including clamp means for securing said tubular member with the second end portion of said core element for retaining said tubular member in its partially withdrawn position.
