Abstract
Abstract A catheter assembly for packaging in sterile condition within a protective removable envelope. The catheter assembly includes an elongated rigid body having a longitudinal bore formed therethrough. A catheter is provided and has its distal end slidingly telescoped into one end of the body bore and the body is provided with longitudinal opposite side generally radial slot portions whereby the body is weakened along longitudinal radial planes extending along the slot portions for separation of the body from about the catheter. A tubular lubricant reservoir is provided and includes a first open end and a second closed end in the form of a collapsible bulbous portion. The tubular reservoir has its open end telescoped over the distal end of the catheter and the corresponding end of the longitudinal bore formed through the body. In addition, the body includes opposite side outwardly projecting shield portions adjacent the distal end of the body and which are supported from the latter for separation away from the associated catheter with the body portions to be separated along the aforementioned radial planes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
205 words
A catheter assembly for packaging in sterile condition within a removable protective envelope, said assembly including an elongated separable body having a longitudinal passageway formed therethrough open at its opposite ends, a catheter having its distal end telescoped into said passageway from one end thereof at one end of said body for subsequent projection of said catheter from the other end of said passageway, said body being provided with, on one side thereof, a longitudinally extending weakened zone and on the opposite side thereof longitudinally spaced and aligned slots, the connecting portions of said opposite side of said body disposed between adjacent ends of adjacent slots and the latter defining a second weakened zone extending longitudinally of said body, whereby said body may be parted along said weakened zones from about said body, and a tubular lubricant reservoir open at one end and having said one end removably telescoped over said distal end of said catheter and within said other end of said passageway, the other end of said tubular reservoir defining a lubricant receiving area and including means operative to cause displacement of said lubricant from said area toward said one end of said tubular reservoir and about said distal end of said catheter.
Claim 2
Dependent Claim
205 words
A catheter assembly for packaging in sterile condition within a removable protective envelope, said assembly including an elongated separable body having a longitudinal passageway formed therethrough open at its opposite ends, a catheter having its distal end telescoped into said passageway from one end thereof at one end of said body for subsequent projection of said catheter from the other end of said passageway, said body being provided with, on one side thereof, a longitudinally extending weakened zone and on the opposite side thereof longitudinally spaced and aligned slots, the connecting portions of said opposite side of said body disposed between adjacent ends of adjacent slots and the latter defining a second weakened zone extending longitudinally of said body, whereby said body may be parted along said weakened zones from about said body, and a tubular lubricant reservoir open at one end and having said one end removably telescoped over said distal end of said catheter and within said other end of said passageway, the other end of said tubular reservoir defining a lubricant receiving area and including means operative to cause displacement of said lubricant from said area toward said one end of said tubular reservoir and about said distal end of said catheter.
Claim 3
Dependent Claim
49 words
The combination of claim 1 wherein said one end of said body includes an endwise outwardly opening cup-shaped shield into the center of whose closed end said one end of said passageway opens, said shield including weakened opposite side areas thereof aligned with said weakened zones of said body.
Claim 4
Dependent Claim
18 words
The combination of claim 1 wherein said one end of said body includes a living body engaging shield.
Claim 5
Dependent Claim
22 words
The combination of claim 3 wherein said shield is supported solely from a portion of said body disposed between said weakened zones.
Claim 6
Dependent Claim
57 words
The combination of claim 1 wherein said tubular lubricant reservoir is constructed of stiff but somewhat resilient material, said lubricant receiving area comprising a hollow and collapsible bulbous enlargement carried by said other end of said tubular reservoir, said means operative to cause lubricant from said area comprising deformable material of which said bulbous enlargement is constructed.
Claim 7
Dependent Claim
78 words
The combination of claim 1 wherein said one end of said tubular lubricant reservoir includes circumferentially spaced lengthwise extending tongue portions supported from the remainder of said reservoir only at the ends thereof adjacent said other end of said reservoir, the outer surfaces of said tongue portions defining wedge surfaces for causing inward displacement of the free ends of said tongue portions in response to seated engagement of said tongue portions in the other end of said passageway.
Claim 8
Dependent Claim
135 words
A catheter assembly for packaging in sterile condition within a removable protective envelope, said assembly including an elongated body having a longitudinal passageway formed therethrough open at its opposite ends, a catheter having its distal end telescoped into said passageway from one end thereof at one end of said body for subsequent projection of said catheter from the other end of said passageway, and a tubular lubricant reservoir open at one end and having said one end removably telescoped over said distal end of said catheter and within said other end of said passageway, the other end of said tubular reservoir defining a lubricant receiving area and including means operative to cause displacement of said lubricant from said area toward said one end of said tubular reservoir and about said distal end of said catheter.
Claim 9
Dependent Claim
135 words
A catheter assembly for packaging in sterile condition within a removable protective envelope, said assembly including an elongated body having a longitudinal passageway formed therethrough open at its opposite ends, a catheter having its distal end telescoped into said passageway from one end thereof at one end of said body for subsequent projection of said catheter from the other end of said passageway, and a tubular lubricant reservoir open at one end and having said one end removably telescoped over said distal end of said catheter and within said other end of said passageway, the other end of said tubular reservoir defining a lubricant receiving area and including means operative to cause displacement of said lubricant from said area toward said one end of said tubular reservoir and about said distal end of said catheter.
Claim 10
Dependent Claim
78 words
The combination of claim 7 wherein said one end of said tubular lubricant reservoir includes circumferentially spaced lengthwise extending tongue portions supported from the remainder of said reservoir only at the ends thEreof adjacent said other end of said reservoir, the outer surfaces of said tongue portions defining wedge surfaces for causing inward displacement of the free ends of said tongue portions in response to seated engagement of said tongue portions in the other end of said passageway.
Claim 11
Dependent Claim
49 words
The combination of claim 7 wherein said one end of said body includes an endwise outwardly opening cup-shaped shield into the center of whose closed end said one end of said passageway opens, said shield including weakened opposite side areas thereof aligned with said weakened zones of said body.
Claim 12
Dependent Claim
57 words
The combination of claim 7 wherein said tubular lubricant reservoir is constructed of stiff but somewhat resilient material, said lubricant receiving areas comprising a hollow and collapsible bulbous enlargement carried by said other end of said tubular reservoir, said means operative to cause lubricant from said area comprising deformable material of which said bulbous enlargement is constructed.
