Abstract
Abstract A steerable catheter comprised of two parts: a catheter body proximally secured to a steerable catheter handle and a catheter tip containing an X-shaped in cross-section lumen secured to the distal end of the catheter body, a pull wire passing through the catheter body and one of the arms of the X-shaped lumen of the catheter tip, one or more electrode wires passing through the catheter body and through a second arm of the X-shaped lumen of the catheter tip and a supporting flat wire passing through the two remaining opposite arms of the X-shaped lumen of the catheter tip.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
144 words
A steerable catheter comprised of (a) a catheter body having proximal and distal ends wherein the catheter body contains a catheter body lumen running from its proximal to its distal end, (b) a catheter tip secured at the distal end of the catheter body containing a lumen, wherein the lumen of the catheter tip is formed into an X-shaped cross-section forming four distinct arms within the X-shaped cross-section of the lumen, (c) a pull wire passing through the lumen of the catheter body and through a portion of the X-shaped lumen of the catheter tip, (d) one or more electrode wires passing through the lumen of the catheter body and through a portion of the X-shaped lumen of the catheter tip, and (e) a supporting flat wire with proximal and distal tips passing through a portion of the X-shaped lumen of the catheter tip.
Claim 2
Dependent Claim
144 words
A steerable catheter comprised of (a) a catheter body having proximal and distal ends wherein the catheter body contains a catheter body lumen running from its proximal to its distal end, (b) a catheter tip secured at the distal end of the catheter body containing a lumen, wherein the lumen of the catheter tip is formed into an X-shaped cross-section forming four distinct arms within the X-shaped cross-section of the lumen, (c) a pull wire passing through the lumen of the catheter body and through a portion of the X-shaped lumen of the catheter tip, (d) one or more electrode wires passing through the lumen of the catheter body and through a portion of the X-shaped lumen of the catheter tip, and (e) a supporting flat wire with proximal and distal tips passing through a portion of the X-shaped lumen of the catheter tip.
Claim 3
Dependent Claim
20 words
The steerable catheter of claim 1 wherein the distal tip of the flat wire is secured to the pull wire.
Claim 4
Dependent Claim
32 words
The steerable catheter of claim 1 wherein the supporting flat wire is surrounded by a sheathing wherein the cross section of the flat wire with sheathing is longer than it is wide.
Claim 5
Dependent Claim
51 words
The steerable catheter of claim 3 wherein the width of the cross section of the supporting flat wire with sheathing is approximately the same as the width of that portion of the X-shaped lumen corresponding to the arms of the X-shaped lumen of the catheter tip containing the supporting flat wire.
Claim 6
Dependent Claim
14 words
The steerable catheter of claim 1 wherein the pull wire is surrounded by sheathing.
Claim 7
Dependent Claim
178 words
A steerable catheter comprised of (a) a catheter body having proximal and distal ends wherein the catheter body contains a catheter body lumen running from its proximal to its distal end, (b) a catheter tip secured to the distal end of the catheter body containing a single, X-shaped cross-sectioned lumen forming four distinct arms within the X-shaped cross-section of the lumen, (c) a pull wire passing through the lumen of the catheter body and through a portion of one arm of the X-shaped lumen of the catheter tip, (d) one or more electrical electrode wires passing through the lumen of the catheter body and through a portion of a second arm of the X-shaped lumen of the catheter tip opposite the arm containing the pull wire, and (e) a supporting flat wire with proximal and distal tips passing through a portion of the lumen of the catheter tip running within the two remaining opposite arms of the X-shaped lumen between the pull wire and the electrical electrode wire thus separating the pull wire from the electrical electrode wire.
Claim 8
Dependent Claim
178 words
A steerable catheter comprised of (a) a catheter body having proximal and distal ends wherein the catheter body contains a catheter body lumen running from its proximal to its distal end, (b) a catheter tip secured to the distal end of the catheter body containing a single, X-shaped cross-sectioned lumen forming four distinct arms within the X-shaped cross-section of the lumen, (c) a pull wire passing through the lumen of the catheter body and through a portion of one arm of the X-shaped lumen of the catheter tip, (d) one or more electrical electrode wires passing through the lumen of the catheter body and through a portion of a second arm of the X-shaped lumen of the catheter tip opposite the arm containing the pull wire, and (e) a supporting flat wire with proximal and distal tips passing through a portion of the lumen of the catheter tip running within the two remaining opposite arms of the X-shaped lumen between the pull wire and the electrical electrode wire thus separating the pull wire from the electrical electrode wire.

Claim 11
Dependent Claim
50 words
The steerable catheter of claim 8 wherein the width of the cross section of the supporting flat wire with sheathing is approximately the same as the width of that portion of the X-shaped lumen corresponding to the arms of the X-shaped lumen of the catheter tip containing the flat wire.
Claim 12
Dependent Claim
