Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
140 words
A catheter device comprising: a percutaneous catheter tube having a distal portion for insertion into the body of a patient; a distal sleeve means having a bushing means at a first end so said distal sleeve means can be slid onto said percutaneous catheter tube and wherein said bushing means is moved adjacent the skin where said catheter tube enters into said patient; and a proximal sleeve means having a first attachment means at one end so said proximal sleeve means can be slid onto said percutaneous catheter tube which extends beyond a second end of said distal sleeve means, said first attachment means being joined to a second attachment means at a second end of said distal sleeve means, and said joined first attachment means and said second attachment means providing a fluid tight seal about said catheter tube.
Claim 2
Dependent Claim
140 words
A catheter device comprising: a percutaneous catheter tube having a distal portion for insertion into the body of a patient; a distal sleeve means having a bushing means at a first end so said distal sleeve means can be slid onto said percutaneous catheter tube and wherein said bushing means is moved adjacent the skin where said catheter tube enters into said patient; and a proximal sleeve means having a first attachment means at one end so said proximal sleeve means can be slid onto said percutaneous catheter tube which extends beyond a second end of said distal sleeve means, said first attachment means being joined to a second attachment means at a second end of said distal sleeve means, and said joined first attachment means and said second attachment means providing a fluid tight seal about said catheter tube.
Claim 3
Dependent Claim
32 words
A catheter device according to claim 1 in which a retaining means is attached to the skin of said patient and said bushing means is brought in contact with said retaining means.
Claim 4
Dependent Claim
18 words
A catheter device according to claim 1 in which said first attachment means includes a male threaded portion.
Claim 5
Dependent Claim
18 words
A catheter device according to claim 3 in which said second attachment means includes a female threaded portion.
Claim 6
Dependent Claim
18 words
A catheter device according to claim 1 in which said first attachment means includes a female threaded portion.
Claim 7
Dependent Claim
18 words
A catheter device according to claim 5 in which said second attachment means includes a male threaded portion.
Claim 8
Dependent Claim
19 words
A catheter device according to claim 1 in which said fluid tight seal is provided by a washer means.
Claim 9
Dependent Claim
28 words
A catheter device according to claim 1 in which said bushing means includes a flange means for providing a second fluid tight seal about said percutaneous catheter tube.
Claim 10
Dependent Claim
28 words
A catheter device according to claim 1 in which said bushing means includes a diaphragm means for providing a second fluid tight seal about said percutaneous catheter tube.
Claim 11
Independent Claim
84 words
A method for catheterization including the steps of: inserting a percutaneous catheter tube in a patient; sliding a distal sleeve means having a bushing means onto said percutaneous catheter tube so said bushing means is adjacent the skin of said patient; sliding a proximal sleeve means having a first attachment means onto said percutaneous catheter tube, and joining said first attachment means to a second attachment means joined to said distal sleeve means to provide a fluid tight seal about said percutaneous catheter tube.
Claim 12
Independent Claim
84 words
A method for catheterization including the steps of: inserting a percutaneous catheter tube in a patient; sliding a distal sleeve means having a bushing means onto said percutaneous catheter tube so said bushing means is adjacent the skin of said patient; sliding a proximal sleeve means having a first attachment means onto said percutaneous catheter tube, and joining said first attachment means to a second attachment means joined to said distal sleeve means to provide a fluid tight seal about said percutaneous catheter tube.
Claim 13
Dependent Claim
34 words
A method of catheterization according to claim 10 including the step of positioning said bushing means so as to be in restrained contact with a retaining means attached to said skin of said patient.
