Abstract
Abstract A catheter defines a flexible, tubular body in which the tubular body carries a tubular reinforcing sleeve made of strands. By this invention the catheter defines at least one side hole which communicates through the tubular body and tubular reinforcing sleeve. Greater resistance against collapse is thus provided to the section of the catheter which defines the side hole or preferably side holes.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
61 words
In a catheter which defines a flexible, tubular body in which said tubular body carries a tubular reinforcing sleeve made of strands, the improvement comprising, in combination: said catheter defining at least one side hole which communicates through said tubular body and strands of said tubular reinforcing sleeve, in which strands of said tubular reinforcing sleeve extend across said side hole.
Claim 2
Dependent Claim
61 words
In a catheter which defines a flexible, tubular body in which said tubular body carries a tubular reinforcing sleeve made of strands, the improvement comprising, in combination: said catheter defining at least one side hole which communicates through said tubular body and strands of said tubular reinforcing sleeve, in which strands of said tubular reinforcing sleeve extend across said side hole.
Claim 3
Dependent Claim
22 words
The catheter of claim 1 in which a plurality of said side holes communicate through said tubular body and tubular reinforcing sleeve.
Claim 4
Dependent Claim
18 words
The catheter of claim 1 in which said strands of the tubular reinforcing sleeve are made of metal.
Claim 5
Dependent Claim
18 words
The catheter of claim 1 in which said catheter carries a distal tip free of said reinforcing sleeve.
Claim 6
Dependent Claim
59 words
The catheter of claim 4 in which said tubular body defines an inner, extruded plastic layer, said tubular reinforcing sleeve surrounding said inner, extruded layer, and an outer, extruded plastic layer surrounding said tubular reinforcing sleeve, said distal tip comprising a portion of said inner, extruded plastic layer extending from said outer layer and reinforcing sleeve in spaced relation.
Claim 7
Dependent Claim
58 words
In a catheter which defines a flexible, tubular body in which said tubular body carrier a tubular reinforcing sleeve made of crossing strands, the improvement comprising, in combination: said catheter defining a plurality of side holes which communicate through the tubular body and tubular reinforcing sleeve, the strands of said tubular reinforcing sleeve extending across said side hole.
Claim 8
Dependent Claim
58 words
In a catheter which defines a flexible, tubular body in which said tubular body carrier a tubular reinforcing sleeve made of crossing strands, the improvement comprising, in combination: said catheter defining a plurality of side holes which communicate through the tubular body and tubular reinforcing sleeve, the strands of said tubular reinforcing sleeve extending across said side hole.

Claim 10
Dependent Claim
18 words
The catheter of claim 7 in which the strands of said tubular reinforcing sleeve are made of metal.
Claim 11
Dependent Claim
67 words
The catheter of claim 6 in which said tubular body defines an inner, extruded plastic layer, said tubular reinforcing sleeve surrounding and adhering to said inner, extruded layer, and an outer, extruded plastic layer surrounding and adhering to said tubular reinforcing sleeve, said distal tip comprising a portion of said inner, extruded plastic layer extending from and substantially free of said outer plastic layer and reinforcing sleeve.
Claim 12
Dependent Claim
22 words
