Abstract
Abstract A catheterization assembly comprises an elongate substantially cylindrical catheter having an outer surface, and a flexible collapsible guide element attached to the outer surface of the catheter at a distal end thereof. A guidewire extends generally parallel to the catheter and through the guide element so that the guide element is held in an extended guide configuration away from the outer surface.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
71 words
A catheter comprising: an elongate substantially cylindrical catheter wall having an outer surface; and flexible guide means including a flap-like appendage attached to said outer surface of said wall at a distal end thereof for flexing between a neutral configuration relatively collapsed against said outer surface and a guide configuration extending outwardly from said outer surface and for slidably attaching, while in said guide configuration, a guidewire to said catheter wall.
Claim 2
Dependent Claim
71 words
A catheter comprising: an elongate substantially cylindrical catheter wall having an outer surface; and flexible guide means including a flap-like appendage attached to said outer surface of said wall at a distal end thereof for flexing between a neutral configuration relatively collapsed against said outer surface and a guide configuration extending outwardly from said outer surface and for slidably attaching, while in said guide configuration, a guidewire to said catheter wall.
Claim 3
Dependent Claim
84 words
A catheter comprising: an elongate substantially cylindrical catheter wall having an outer surface; and flexible guide means including a plurality of flexible guide elements spaced from one another longitudinally along said wall and attached to said outer surface of said wall at a distal end thereof for flexing between a neutral configuration relatively collapsed against said outer surface and a guide configuration extending outwardly from said outer surface and for slidably attaching, while in said guide configuration, a guide wire to said catheter wall.
Claim 4
Dependent Claim
84 words
A catheter comprising: an elongate substantially cylindrical catheter wall having an outer surface; and flexible guide means including a plurality of flexible guide elements spaced from one another longitudinally along said wall and attached to said outer surface of said wall at a distal end thereof for flexing between a neutral configuration relatively collapsed against said outer surface and a guide configuration extending outwardly from said outer surface and for slidably attaching, while in said guide configuration, a guide wire to said catheter wall.
Claim 5
Dependent Claim
26 words
The catheter defined in claim 2 wherein said guide elements have different effective lengths, whereby the guidewire passes at a varying distance from said outer surface.
Claim 6
Dependent Claim
41 words
The catheter defined in claim 3 wherein a relatively distal one of said guide elements has a longer effective length than a relatively proximal one of said guide elements, whereby said guidewire diverges from said wall at said distal end thereof.
Claim 7
Dependent Claim
41 words
The catheter defined in claim 3 wherein a relatively distal one of said guide elements has a shorter effective length than a relatively proximal one of said guide elements, whereby said guidewire converges towards said wall at said distal end thereof.
Claim 8
Dependent Claim
19 words
The catheter defined in claim 2 wherein said flexible guide means includes a thread-like loop attached to said wall.
Claim 9
Dependent Claim
23 words
The catheter defined in claim 6 wherein said loop is provided along its length with a smaller, ancillary loop for receiving said guidewire.
Claim 10
Dependent Claim
18 words
The catheter defined in claim 2 wherein said flexible guide means includes a flap-like appendage on said wall.
Claim 11
Dependent Claim
73 words
A catheterization assembly comprising: an elongate substantially cylindrical catheter having an outer surface; a plurality of flexible collapsible guide elements attached to said outer surface of said catheter at a distal end thereof and spaced from one another longitudinally along said catheter; and a guidewire extending generally parallel to said catheter and through said guide elements so that said guide elements are held in an extended guide configuration away from said outer surface.
Claim 12
Dependent Claim
73 words
A catheterization assembly comprising: an elongate substantially cylindrical catheter having an outer surface; a plurality of flexible collapsible guide elements attached to said outer surface of said catheter at a distal end thereof and spaced from one another longitudinally along said catheter; and a guidewire extending generally parallel to said catheter and through said guide elements so that said guide elements are held in an extended guide configuration away from said outer surface.
Claim 13
Dependent Claim
27 words
The catherization assembly defined in claim 9 wherein said guide elements have different effective lengths, whereby the guidewire passes at a varying distance from said outer surface.
Claim 14
Dependent Claim
42 words
The catherization assembly defined in claim 10 wherein a relatively distal one of said guide elements has a longer effective length than a relatively proximal one of said guide elements, whereby said guidewire diverges from said catheter at said distal end thereof.
Claim 15
Dependent Claim
42 words
The catherization assembly defined in claim 10 wherein a relatively distal one of said guide elements has a shorter effective length than a relatively proximal one of said guide elements, whereby said guidewire converges towards said catheter at said distal end thereof.
Claim 16
Dependent Claim
19 words
The catherization assembly defined in claim 9 wherein said flexible guide elements are thread-like loops attached to said catheter.
Claim 17
Dependent Claim
23 words
The catherization assembly defined in claim 13 wherein said loops are provided along their lengths with smaller, ancillary loops for receiving said guidewire.
Claim 18
Dependent Claim
18 words
The catherization assembly defined in claim 9 wherein said flexible guide elements are flap-like appendages on said catheter.
Claim 19
Dependent Claim
32 words
The catherization assembly defined in claim 9 wherein said guide elements are formed with an inherent spring bias tending to hold said guide element in a collapsed configuration against said outer surface.
Claim 20
Dependent Claim
69 words
A catheterization assembly comprising: an elongate substantially cylindrical catheter having an outer surface; a flexible collapsible guide element in the form of a flap-like appendage attached to said outer surface of said catheter at a distal end thereof; and a guidewire extending generally parallel to said catheter and through said guide element so that said guide element is held in an extended guide configuration away from said outer surface.
Claim 21
Dependent Claim
69 words
A catheterization assembly comprising: an elongate substantially cylindrical catheter having an outer surface; a flexible collapsible guide element in the form of a flap-like appendage attached to said outer surface of said catheter at a distal end thereof; and a guidewire extending generally parallel to said catheter and through said guide element so that said guide element is held in an extended guide configuration away from said outer surface.
Claim 22
Dependent Claim
86 words
A catheterization assembly comprising: an elongate substantially cylindrical catheter having an outer surface; a flexible collapsible guide element attached to said outer surface of said catheter at a distal end thereof, said guide element being formed with an inherent spring bias tending to hold said guide element in a collapsed configuration against said outer surface; and a guidewire extending generally parallel to said catheter and through said guide element so that said guide element is held in an extended guide configuration away from said outer surfaces.
