Abstract
Abstract A urethral introduction catheter comprising an elongated flexible catheter fixed at its proximal end to a connector and having a cap removably mounted on the drain spout end thereof. The proximal end of the catheter slidably extends through an introducer having a predetermined quantity of water-soluble lubricant provided therein. The introducer is provided with an end portion through which the catheter passes. A flexible sheath is secured to and extends between the connector and introducer to maintain the catheter in a sterile condition. A cap is provided for sealing the introducer prior to use. The method of using the device is also disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A urethral introduction catheter comprising, an elongated flexible catheter having distal and proximal ends, a connector secured to said catheter adjacent the proximal end thereof, said catheter having a drain spout portion extending from said connector, an introducer having a catheter introducer end portion extending therefrom, a sterile lubricant in said introducer, the distal end of said catheter being movably received by said introducer and slidably received by said introducer end portion so that the sterile lubricant is pushed from said introducer into the patient''s urethra as the catheter is inserted into the patient''s urethra, and a flexible sheath secured at its proximal end to said connector and secured at its distal end to said introducer.
Claim 2
Dependent Claim
116 words
A urethral introduction catheter comprising, an elongated flexible catheter having distal and proximal ends, a connector secured to said catheter adjacent the proximal end thereof, said catheter having a drain spout portion extending from said connector, an introducer having a catheter introducer end portion extending therefrom, a sterile lubricant in said introducer, the distal end of said catheter being movably received by said introducer and slidably received by said introducer end portion so that the sterile lubricant is pushed from said introducer into the patient''s urethra as the catheter is inserted into the patient''s urethra, and a flexible sheath secured at its proximal end to said connector and secured at its distal end to said introducer.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1 wherein a first cap means is removably mounted on said drain spout portion.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 wherein a second cap means is removably mounted on said introducer end portion.
Claim 5
Independent Claim
139 words
The method of catheterizing a patient comprising the steps of: providing an introducer having a passageway formed therein containing a sterile lubricant normally stored therein, said introducer having an end portion adapted for insertion into the patient''s urethra, said introducer having an opposite end which is adapted to receive a catheter tube, the relationship of the catheter tube and said introducer passageway being such that the catheter tube will eject the lubricant from said passageway as said catheter tube is moved therethrough, inserting said introducer end portion into the patient''s urethra, moving the catheter tube through said passageway so that the sterile lubricant is ejected from said introducer into the patient''s urethra as the catheter tube is inserted therein, said catheter tube pushing said lubricant from said introducer simultaneously with the insertion of the catheter tube into the urethra.
Claim 6
Independent Claim
139 words
The method of catheterizing a patient comprising the steps of: providing an introducer having a passageway formed therein containing a sterile lubricant normally stored therein, said introducer having an end portion adapted for insertion into the patient''s urethra, said introducer having an opposite end which is adapted to receive a catheter tube, the relationship of the catheter tube and said introducer passageway being such that the catheter tube will eject the lubricant from said passageway as said catheter tube is moved therethrough, inserting said introducer end portion into the patient''s urethra, moving the catheter tube through said passageway so that the sterile lubricant is ejected from said introducer into the patient''s urethra as the catheter tube is inserted therein, said catheter tube pushing said lubricant from said introducer simultaneously with the insertion of the catheter tube into the urethra.
Claim 7
Dependent Claim
162 words
A urethral introduction catheter comprising, an elongated flexible catheter tube having distal and proximal ends, a connector secured to said catheter tube adjacent the proximal end thereof, said catheter tube having a drain spout portion extending from said connector, said catheter tube having at least one opening formed therein adjacent its distal end, an introducer having a bore extending therethrough, said introducer including an end portion, said bore communicating with said end portion, the distal end of said catheter tube being slidably received by said bore, a flexible sheath secured at its proximal end to said connector and secured at its distal end to said introducer, a sterile lubricant positioned in said bore between the distal end of said catheter tube and said introducer end portion, the relationship of said bore and said catheter tube being such that said catheter tube will push said lubricant from said bore into the patient''s urethra as the catheter tube is slidably extended through said bore.
Claim 8
Dependent Claim
162 words
A urethral introduction catheter comprising, an elongated flexible catheter tube having distal and proximal ends, a connector secured to said catheter tube adjacent the proximal end thereof, said catheter tube having a drain spout portion extending from said connector, said catheter tube having at least one opening formed therein adjacent its distal end, an introducer having a bore extending therethrough, said introducer including an end portion, said bore communicating with said end portion, the distal end of said catheter tube being slidably received by said bore, a flexible sheath secured at its proximal end to said connector and secured at its distal end to said introducer, a sterile lubricant positioned in said bore between the distal end of said catheter tube and said introducer end portion, the relationship of said bore and said catheter tube being such that said catheter tube will push said lubricant from said bore into the patient''s urethra as the catheter tube is slidably extended through said bore.
Claim 9
Dependent Claim
32 words
The apparatus of claim 5 wherein said catheter has an outside diameter substantially equal to the inside diameter of said bore to prevent said lubricant from entering said opening in said catheter.
Claim 10
Dependent Claim
12 words
The apparatus of claim 5 wherein said lubricant comprises a water-soluble lubricant.
