Abstract
Abstract The invention provides a guide catheter comprising an elongate tubular body having a proximal end and a distal end, and at least one central lumen extending axially therethrough. At least one torque control wire extends axially therethrough. In one embodiment, an actuator is connected to the torque control wire. Torquing the actuator results in steering or aiming the guide catheter. In another embodiment, a deflection wire extends through the catheter body. Manipulation of a control on the deflection wire deflects a distal portion of the deflection wire.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
82 words
A catheter, comprising: an elongate flexible tubular body having a wall, a proximal end and a distal end, at least one central lumen extending axially therethrough, and at least one wire extending axially therethrough, at least a portion of said wire being fixed along its length to said tubular body so that rotation of the wire applies torque to the tubular body; wherein the tubular body is manually bendable and the wire retains a set if the tubular body is manually bent.
Claim 2
Dependent Claim
82 words
A catheter, comprising: an elongate flexible tubular body having a wall, a proximal end and a distal end, at least one central lumen extending axially therethrough, and at least one wire extending axially therethrough, at least a portion of said wire being fixed along its length to said tubular body so that rotation of the wire applies torque to the tubular body; wherein the tubular body is manually bendable and the wire retains a set if the tubular body is manually bent.
Claim 3
Dependent Claim
17 words
A catheter as in claim 1, wherein said elongate flexible tubular body comprises a single layer wall.
Claim 4
Dependent Claim
15 words
A catheter as in claim 2, wherein the wire extends axially through the single wall.
Claim 5
Dependent Claim
31 words
A catheter as in claim 1, wherein said wire comprises an outer cylindrical housing having a central lumen extending therethrough, and an inner core wire axially movably positioned within the lumen.
Claim 6
Dependent Claim
61 words
A catheter as in claim 4, wherein said cylindrical housing has a distal end, and further comprising an axially extending support extending in a distal direction from the distal end of the cylindrical housing the support axially fixed with respect to the core wire such that proximal displacement of the core wire laterally displaces at least a portion of the support.
Claim 7
Dependent Claim
129 words
A catheter, comprising: an elongate flexible tubular body having a wall, a proximal end and a distal end, at least one central lumen extending axially therethrough; at least one wire extending axially through the tubular body, said wire comprising an outer cylindrical housing having a distal end and a central lumen extending therethrough, and an inner core wire axially movably positioned within the lumen; and an axially extending support extending in a distal direction from the distal end of the cylindrical housing, the support axially fixed with respect to the core wire such that proximal displacement of the core wire laterally displaces at least a portion of the support; wherein the tubular body is manually bendable and the wire retains a set if the tubular body is manually bent.
Claim 8
Dependent Claim
129 words
A catheter, comprising: an elongate flexible tubular body having a wall, a proximal end and a distal end, at least one central lumen extending axially therethrough; at least one wire extending axially through the tubular body, said wire comprising an outer cylindrical housing having a distal end and a central lumen extending therethrough, and an inner core wire axially movably positioned within the lumen; and an axially extending support extending in a distal direction from the distal end of the cylindrical housing, the support axially fixed with respect to the core wire such that proximal displacement of the core wire laterally displaces at least a portion of the support; wherein the tubular body is manually bendable and the wire retains a set if the tubular body is manually bent.
Claim 9
Dependent Claim
17 words
A catheter as in claim 6, wherein said elongate flexible tubular body comprises a single layer wall.
Claim 10
Dependent Claim
15 words
A catheter as in claim 7, wherein the wire extends axially through the single wall.
Claim 11
Dependent Claim
102 words
A steerable guide or angiographic catheter comprising: an elongate flexible tubular body having a proximal end, a distal end, and at least one central lumen extending axially therethrough; at least one wire extending axially through the tubular body, said wire being fixed with respect to the tubular body wherein rotation of said wire results in rotating the distal end of said catheter; an elongate flexible deflection element extending through the tubular body, said deflection element comprising first and second axially extending components; wherein proximal advancement of the first component relative to the second component causes a lateral deflection of the distal end.
Claim 12
Dependent Claim
102 words
A steerable guide or angiographic catheter comprising: an elongate flexible tubular body having a proximal end, a distal end, and at least one central lumen extending axially therethrough; at least one wire extending axially through the tubular body, said wire being fixed with respect to the tubular body wherein rotation of said wire results in rotating the distal end of said catheter; an elongate flexible deflection element extending through the tubular body, said deflection element comprising first and second axially extending components; wherein proximal advancement of the first component relative to the second component causes a lateral deflection of the distal end.
