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.
Claims14
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.
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.
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 end to its distal end,
- (b) a catheter tip secured at 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 pair of pull wires passing through the lumen of the catheter body and through a portion of separate arms of the X-shaped lumen of the catheter tip, wherein the arms containing the pull wires are opposite each other,
- (d) one or more electrical electrode wires passing through the lumen of the catheter body and through a portion of the arms of the X-shaped lumen of the catheter tip containing the pull wire, and
- (e) a flat supporting wire passing through a portion of the lumen of the catheter tip running within the two remaining opposite arms of the X-shaped lumen.
