Claims
- 1. An introducer, comprising:an elongated tube having first and second lumens; a molded handle coupled to the proximal end of the tube, having a proximal opening aligned with the first lumen of the tube and having a wall adjacent the opening of the handle which defines a slot, located diametrically opposite the second lumen of the tube; and a tubular reinforcement member located within the second lumen of the tube, the handle also being provided with a second opening, open to the second lumen of the tube.
- 2. An introducer according to claim 1 wherein the tubular reinforcement member is a coil.
- 3. An introducer according to claim 2 wherein the tubular reinforcement member is a metal coil.
- 4. An introducer according to claim 1 wherein the tubular reinforcement member is a braid.
- 5. An introducer according to claim 2 wherein the tubular reinforcement member is a metal braid.
- 6. An introducer according to claim 1 wherein the tubular reinforcement member is a metal member.
- 7. An introducer according to claim 1 wherein a portion of the handle extends laterally from the tube in a direction diametrically opposite from the slot.
- 8. An introducer according to claim 7 wherein the second opening of the handle is located in the laterally extending portion of the handle.
- 9. A lead/catheter introducer system comprising:an implantable lead or catheter; an introducer having an elongated first lumen through which the lead or catheter passes and a second lumen, extending parallel to the first lumen along at least a distal portion thereof; a tubular reinforcement member located within the second lumen of the tube, the tubular reinforcement member in turn having an internal lumen; and a curvable stylet, located in the lumen of the tubular reinforcement member.
- 10. A system according to claim 9 wherein the tubular reinforcement member is a coil.
- 11. A system according to claim 10 wherein the tubular reinforcement member is a metal coil.
- 12. A system according to claim 9 wherein the tubular reinforcement member is a braid.
- 13. A system according to claim 12 wherein the tubular reinforcement member is a metal braid.
- 14. A system according to claim 9 wherein the tubular reinforcement member is a metal member.
- 15. A method of locating a lead or catheter in a desired location within a patient's body, comprising:inserting the lead or catheter into a first longitudinal lumen of a guide sheath; inserting a stylet into a second longitudinal lumen of the guide sheath; advancing the guide sheath, stylet and the catheter or lead to the desired location in the patient's body; removing the stylet; and removing the guide sheath from the lead or catheter by opening an outer wall of the first lumen along its length and removing the guide sheath from the lead or catheter.
- 16. A method according to claim 15, wherein the step of opening the wall of the guide sheath comprises slitting the wall.
- 17. A method according to claim 16, wherein the step of slitting the wall comprises slitting the wall along a portion of the wall located diametrically opposite the second longitudinal lumen.
- 18. A method of locating a lead or catheter in a desired location within a patient's body, comprising:inserting the lead or catheter into a first longitudinal lumen of a guide sheath; inserting a stylet into a second longitudinal lumen of the guide sheath having a tubular reinforcement member located therein; advancing the guide sheath, stylet and the catheter or lead to the desired location in the patient's body; removing the stylet; and removing the guide sheath from the lead or catheter by opening an outer wall of the first lumen along its length and removing the guide sheath from the lead or catheter.
- 19. A method according to claim 18, wherein the step of opening the wall of the guide sheath comprises slitting the wall.
- 20. A method according to claim 19, wherein the step of slitting the wall comprises slitting the wall along a portion of the wall located diametrically opposite the second longitudinal lumen.
- 21. A method of locating a lead or catheter in a desired location within a patient's body, comprising:inserting the lead or catheter into a first longitudinal lumen of a guide sheath; inserting a stylet into a second longitudinal lumen of the guide sheath having a coiled reinforcement member located therein; advancing the guide sheath, stylet and the catheter or lead to the desired location in the patient's body; removing the stylet; and removing the guide sheath from the lead or catheter by opening an outer wall of the first lumen along its length and removing the guide sheath from the lead or catheter.
- 22. A method according to claim 21, wherein the step of opening the wall of the guide sheath comprises slitting the wall.
- 23. A method according to claim 21, wherein the step of slitting the wall comprises slitting the wall along a portion of the wall located diametrically opposite the second longitudinal lumen.
