Abstract
Abstract Guiding catheter assembly (11) adapted to be inserted into a vessel having a first guiding catheter (12) and a second guiding catheter (13) removably disposed within the first guiding catheter (12). The second guiding catheter (13) has a length so that it extends beyond the distal extremity of the first guiding catheter (13). Each of the first and second guiding catheters (12, 13) includes a flexible elongate tubular member (16, 18) having a bore (17, 19) extending therethrough and a fitting (31) secured to the proximal extremity of the tubular member (16, 18). The bore (17, 19) in the tubular member (16, 18) is of a size so that the portion of the second guiding catheter (13) extending beyond the fitting (31) can be introduced into the bore (17) of the tubular member (16) of the first guiding catheter (12).

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
114 words
In a guiding catheter assembly adapted to be inserted into a vessel, a first guiding catheter and a second guiding catheter removably disposed within the first guiding catheter and having a length so that it extends beyond the distal extremity of the first guiding catheter, each of said first and second guiding catheters including a flexible elongate tubular member having a bore extending therethrough and a fitting secured to the proximal extremity of the tubular member, the bore in the tubular member being of a size so that the portion of the second guiding catheter extending beyond the fitting can be introduced into the bore of the tubular member of the first guiding catheter.
Claim 2
Dependent Claim
114 words
In a guiding catheter assembly adapted to be inserted into a vessel, a first guiding catheter and a second guiding catheter removably disposed within the first guiding catheter and having a length so that it extends beyond the distal extremity of the first guiding catheter, each of said first and second guiding catheters including a flexible elongate tubular member having a bore extending therethrough and a fitting secured to the proximal extremity of the tubular member, the bore in the tubular member being of a size so that the portion of the second guiding catheter extending beyond the fitting can be introduced into the bore of the tubular member of the first guiding catheter.
Claim 3
Dependent Claim
41 words
An assembly as claimed in Claim 1 wherein said tubular member is comprised solely of braided ribbons having a cured plastic material impregnated therein providing a smooth inner surface defining the bore and additional cured plastic providing a smooth outer surface.
Claim 4
Dependent Claim
22 words
A guiding catheter as claimed in Claim 2 wherein said tubular member includes an outer plastic layer having an opaque coloring therein.
Claim 5
Dependent Claim
29 words
A guiding catheter as claimed in Claims 1, 2 or 3, wherein the tips of the flexible tubular members are relatively soft and are free of the braided ribbons.
Claim 6
Dependent Claim
19 words
A guiding catheter as claimed in Claim 2 wherein said braided ribbons are formed of Kevlar 49 aramid yarns.
Claim 7
Dependent Claim
76 words
A catheter assembly as claimed in Claims 1, 2, 3, 4 or 5 together with a hub mounted on the proximal end of each tubular member, and fitting carried by the second catheter and adapted to said seat in the hub provided on the proximal extremity of the outer guiding catheter to provide a liquid tight seal and also to retain the inner guiding catheter in a predetermined position with respect to the outer guiding catheter.
Claim 8
Dependent Claim
42 words
In a guiding catheter, a flexible tubular member having a bore extending therethrough, said tubular member being comprised of a jacket formed solely of braided ribbons having a cured plastic material impregnated therein and providing a smooth inner surface defining the bore.
Claim 9
Dependent Claim
42 words
In a guiding catheter, a flexible tubular member having a bore extending therethrough, said tubular member being comprised of a jacket formed solely of braided ribbons having a cured plastic material impregnated therein and providing a smooth inner surface defining the bore.
Claim 10
Dependent Claim
13 words
A catheter as claimed in Claim 7 wherein said plastic material is polyurethane.
Claim 11
Dependent Claim
30 words
A catheter as claimed in Claims 7 or 8, together with additional layers of plastic formed on said braided jacket and wherein one of said layers includes an opaque coloring.
Claim 12
Dependent Claim
25 words
A catheter as claimed in Claims 7, 8 or 9, wherein the distal extremity of the tubular members has a radiopaque powder incorporated in same.
Claim 13
Dependent Claim
12 words
A catheter as claimed in Claim 10 wherein radiopaque powder includes tantalum.
Claim 14
Dependent Claim
34 words
A catheter as claimed in Claims 7, 8, 9, 10 or 11, together with at least one additional layer 4 plastic formed on said jacket, said layer being centerless ground to a precise diameter.
Claim 15
Dependent Claim
21 words
A catheter as in Claim 1 wherein each of the first and second guiding catheters is provided with a soft tip.
Claim 16
Dependent Claim
82 words
In a method for making a guiding catheter, providing a mandrel formed of a material having a smooth outer surface, braiding a jacket of ribbons comprised of yarn onto said mandrel, impregnating said ribbons with a plastic material and curing the same so that a smooth inner surface is provided engaging the mandrel, removing the mandrel so that there is provided a flexible tubular member which is formed solely of the braided ribbons having a cured plastic material impregnated therein and thereon.
Claim 17
Dependent Claim
82 words
In a method for making a guiding catheter, providing a mandrel formed of a material having a smooth outer surface, braiding a jacket of ribbons comprised of yarn onto said mandrel, impregnating said ribbons with a plastic material and curing the same so that a smooth inner surface is provided engaging the mandrel, removing the mandrel so that there is provided a flexible tubular member which is formed solely of the braided ribbons having a cured plastic material impregnated therein and thereon.
Claim 18
Dependent Claim
21 words
A method as claimed in Claim 14 together with the step of applying additional layers of plastic onto the braided jacket.
Claim 19
Dependent Claim
24 words
A method as claimed in Claim 15 together with the step of adding an opaque coloring to one of the layers of plastic material.
Claim 20
Dependent Claim
28 words
A method as claimed in Claim 14 together with the step of impregnating the distal extremity of at least one of the plastic layers with a radiopaque powder.
Claim 21
Dependent Claim
25 words
A method as claimed in Claim 14 together with the step of placing a predetermined bend in the distal extremity of the flexible tubular member.
