Abstract

Abstract A uniplanar medical steering device which includes a tubular member of a material such as stainless steel, a hinge formed by a cut-out in a wall of the tubular member and a control wire for bending a first end of the tubular member back and forth in a plane towards and away from a second end of the tubular member. A medical device such as a catheter can be provided within the tubular member and an outer member surrounding the tubular member can be used to cover the cut-out. The steering device allows accurate positioning of a medical device and prevents twisting of the medical device when bent by the control wire.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 120 words
A medical uniplanar steering device comprising: a tubular member having first and second spaced-apart ends and a central opening extending axially between the first and second ends; hinge means for connecting the first end to the second end and permitting uniplanar bending of the first end back and forth in a plane towards and away from the second end, the hinge means comprising a cut-out in a wall of the tubular member; and articulating means for moving the first end in the plane towards the second end of the tubular member, the articulating means comprising a control wire located on a side of the tubular member opposite to a side of the tubular member in which the cut-out is located.
Claim 2
Dependent Claim 120 words
A medical uniplanar steering device comprising: a tubular member having first and second spaced-apart ends and a central opening extending axially between the first and second ends; hinge means for connecting the first end to the second end and permitting uniplanar bending of the first end back and forth in a plane towards and away from the second end, the hinge means comprising a cut-out in a wall of the tubular member; and articulating means for moving the first end in the plane towards the second end of the tubular member, the articulating means comprising a control wire located on a side of the tubular member opposite to a side of the tubular member in which the cut-out is located.
Claim 3
Dependent Claim 57 words
The device of claim 1, wherein the control wire is attached to the first end of the tubular member, the control wire extending along the tubular member and beyond the second end of the tubular member, the control wire causing the first end to bend towards the second end when tension is applied to the control wire.
Claim 4
Dependent Claim 19 words
The device of claim 1, wherein the control wire is located on an outer periphery of the tubular member.
Claim 5
Dependent Claim 31 words
The device of claim 1, wherein the tubular member has a circular cross section and the tubular member is substantially uniform in diameter from the first end to the second end.
Claim 6
Dependent Claim 14 words
The device of claim 1, wherein the tubular member comprises a stainless steel tube.
Claim 7
Dependent Claim 43 words
The device of claim 1, wherein the cut-out is located between the first and second ends, the cut-out being defined by a circumferential section of the tubular member which extends circumferentially generally no more than one-fourth of a distance around the tubular member.
Claim 8
Dependent Claim 29 words
The device of claim 1, wherein the cut-out extends a distance along the tubular member, the distance being greater than a distance around a circumference of the tubular member.
Claim 9
Dependent Claim 17 words
The device of claim 1, wherein the cut-out extends circumferentially more than halfway around the tubular member.
Claim 10
Dependent Claim 38 words
The device of claim 1, wherein the cut-out is defined by two spaced-apart longitudinally extending side edges of the wall, the side edges being parallel to each other and parallel to a central axis of the tubular member.
Claim 11
Dependent Claim 37 words
The device of claim 1, wherein the cut-out is defined by two spaced-apart longitudinally extending side edges of the wall, the side edges lying a plane which is non-parallel to a central axis of the tubular member.
Claim 12
Dependent Claim 28 words
The device of claim 1, wherein the cut-out is tapered and the cut-out is larger at an end thereof closest to the first end of the tubular member.
Claim 13
Dependent Claim 31 words
The device of claim 1, wherein the cut-out is defined by two axially spaced-apart end edges of the wall, the end edges lying in planes which are parallel to each other.
Claim 14
Dependent Claim 48 words
The device of claim 1, wherein the cut-out is defined by two circumferentially spaced-apart side edges of the wall and two axially spaced-apart end edges of the wall, the end edges being joined to the side edges by arcuate corner edges in the wall of the tubular member.
Claim 15
Dependent Claim 51 words
The device of claim 1, further comprising a medical device, the medical device having a distal end thereof extending beyond the first end of the tubular member, the distal end of the medical device being oriented in a desired direction lying in the plane by applying tension to the control wire.
Claim 16
Dependent Claim 34 words
The device of claim 1, further comprising a catheter within the tubular member, the catheter including a balloon at a distal end of the catheter extending beyond the first end of the tubular member.
Claim 17
Dependent Claim 21 words
The device of claim 1, further comprising an outer member surrounding the tubular member, the outer member completely covering the cut-out.
