Abstract
Abstract A catheter such as a medical catheter for PTCA procedures or the like. The catheter has a longitudinally extending wire therein, typically a steering wire. A catheter hub is positioned on the proximal end of the catheter. By this invention, the wire defines a coiled end positioned within a bore of the catheter hub and secured to the hub. Thus, fluids can flow through the bore of the hub and coiled wire end to and from the catheter, for example for the purpose of inflating or deflating a catheter balloon. At the same time, the same hub can be used to steer the distal end of the catheter by rotation of the hub in a conventional catheter steering technique.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
81 words
In a catheter having a longitudinally extending steering wire therein and a catheter hub positioned on an end of said catheter, the improvement comprising, in combination: said hub defining a bore, said wire defining a generally straight portion comprising most of the length of said wire and a coiled end unitary with said straight portion and positioned within said bore and secured to said hub, whereby fluids can flow through said bore and coiled wire end to and from said catheter.
Claim 2
Dependent Claim
81 words
In a catheter having a longitudinally extending steering wire therein and a catheter hub positioned on an end of said catheter, the improvement comprising, in combination: said hub defining a bore, said wire defining a generally straight portion comprising most of the length of said wire and a coiled end unitary with said straight portion and positioned within said bore and secured to said hub, whereby fluids can flow through said bore and coiled wire end to and from said catheter.
Claim 3
Dependent Claim
30 words
The catheter of claim 1 in which said hub carries a tubular strain relief member, a portion of the catheter and wire being positioned within said tubular strain relief member.
Claim 4
Dependent Claim
34 words
The catheter of claim 2 in which a portion of said coiled end is bonded to said hub within said bore, and a portion of said coiled end occupies said tubular strain relief member.
Claim 5
Dependent Claim
20 words
The catheter of claim 1 in which said hub is molded about at least a portion of said coiled end.
Claim 6
Dependent Claim
37 words
The catheter of claim 1 in which said hub serves both for providing fluid connection to the interior of the catheter and for steering the catheter with said wire, said catheter being free of any other hub.
Claim 7
Dependent Claim
18 words
The catheter of claim 5 which carries a balloon which is inflatable by fluid passing through said hub.
Claim 8
Dependent Claim
138 words
In a catheter having a longitudinally extending steering wire therein and a catheter hub positioned on the proximal end of said catheter, said catheter defining an inflatable balloon member positioned adjacent the distal end of said catheter, the improvement comprising, in combination: said hub defining a bore, said wire defining a generally straight portion comprising most of the length of said wire and a coiled end unitary with said straight portion and positioned within said bore and secured in said hub, whereby fluids can flow through said bore and coiled wire end to and from said catheter to inflate and deflate the balloon of said catheter, said hub serving both for providing said fluid connection for inflating and deflating the catheter balloon and for steering the catheter with said wire, said catheter being free of any other hub.
Claim 9
Dependent Claim
138 words
In a catheter having a longitudinally extending steering wire therein and a catheter hub positioned on the proximal end of said catheter, said catheter defining an inflatable balloon member positioned adjacent the distal end of said catheter, the improvement comprising, in combination: said hub defining a bore, said wire defining a generally straight portion comprising most of the length of said wire and a coiled end unitary with said straight portion and positioned within said bore and secured in said hub, whereby fluids can flow through said bore and coiled wire end to and from said catheter to inflate and deflate the balloon of said catheter, said hub serving both for providing said fluid connection for inflating and deflating the catheter balloon and for steering the catheter with said wire, said catheter being free of any other hub.
Claim 10
Dependent Claim
31 words
The catheter of claim 7 in which said hub carries a tubular strain relief member, a portion of the catheter and steering wire being positioned within said tubular strain relief member.
Claim 11
Dependent Claim
34 words
The catheter of claim 8 in which a portion of said coiled end is bonded to said hub within said bore, and a portion of said coiled end occupies said tubular strain relief member.
Claim 12
Dependent Claim
20 words
The catheter of claim 7 in which said hub is molded about at least a portion of said coiled end.
Claim 13
Dependent Claim
19 words
The catheter of claim 7 which defines a catheter body, said catheter body being directly bonded to said hub.
Claim 14
Dependent Claim
103 words
In a catheter having a longitudinally extending steering wire therein and a catheter hub positioned on an end of said catheter, the improvement comprising, in combination: said hub defining a bore, said wire defining a generally straight portion comprising a substantial portion of the length of said wire and a coiled end unitary with said straight portion and positioned within said bore, said hub defining a plastic member which has been insert molded into position about said coiled end for securance of said hub and wire together, whereby fluids can flow through said bore and coiled wire end to and from said catheter.
Claim 15
Dependent Claim
103 words
In a catheter having a longitudinally extending steering wire therein and a catheter hub positioned on an end of said catheter, the improvement comprising, in combination: said hub defining a bore, said wire defining a generally straight portion comprising a substantial portion of the length of said wire and a coiled end unitary with said straight portion and positioned within said bore, said hub defining a plastic member which has been insert molded into position about said coiled end for securance of said hub and wire together, whereby fluids can flow through said bore and coiled wire end to and from said catheter.
Claim 16
Dependent Claim
16 words
The catheter of claim 12 which carries a balloon inflatable by fluid passing through said hub.
