Abstract
A medical dilator includes an elongate member having a proximal end portion, an opposed distal end portion, and a lumen extending through the elongate member from the proximal end portion to the distal end portion. A dilating tip is at the distal end portion. The dilating tip has a first end of enlarged cross-sectional area and tapers going in the distal direction to a second end of reduced cross-sectional area. At least a first electrode is associated with the dilating tip. An electrical conductor is electrically connected to the first electrode and extends proximally from the first electrode towards the proximal end portion for electrical connection with an electro anatomical mapping system.

A medical dilator, comprising:
- an elongate member having a proximal end portion, an opposed distal end portion, and a lumen extending through the elongate member from the proximal end portion to the distal end portion;
- a dilating tip at the distal end portion, the dilating tip having a first end of enlarged cross- sectional area and tapering going in the distal direction to a second end of reduced cross-sectional area;
- a first electrode associated with the dilating tip;
- the dilating tip including a proximal piece having a distal-facing shoulder surface and a neck extending distally from the shoulder surface;
- the dilating tip further including a distal piece received on the neck distal to and abutting the first electrode;
- the first electrode having an annular shape and being positioned on the neck and abutting the distal-facing shoulder surface;
- and
- an electrical conductor electrically connected to the first electrode and extending proximally from the first electrode towards the proximal end portion for electrical connection with an electroanatomical mapping system.
A kit of parts for medical perforation system, the kit of parts comprising:
- a medical dilator comprising an elongate member having a proximal end portion, an opposed distal end portion, and a lumen extending through the elongate member from the proximal end portion to the distal end portion;
- a dilating tip at the distal end portion, the dilating tip having first end of enlarged cross-sectional area and tapering going in the distal direction to a second end of reduced cross-sectional area;
- the dilating tip including a proximal piece having a distal-facing shoulder surface and a neck extending distally from the shoulder surface;

- an electrical conductor electrically connected to the first electrode and extending proximally from the first electrode to the proximal end portion for electrical connection with an electroanatomical mapping system, wherein the electrical conductor is electrically insulated between the first electrode and the electroanatomical mapping system;
- a sheath for receiving the medical dilator;
- and
- a perforation device receivable in the lumen.
A medical dilation system, comprising:
- a medical dilator comprising an elongate member having a proximal end portion, an opposed distal end portion, and a lumen extending through the elongate member from the proximal end portion to the distal end portion;
- a dilating tip at the distal end portion, the dilating tip having first end of enlarged cross-sectional area and tapering going in the distal direction to a second end of reduced cross-sectional area;
- the dilating tip including a proximal piece having a distal-facing shoulder surface and a neck extending distally from the shoulder surface;
- the dilating tip further including a distal piece received on the neck;
- at least a first electrode associated with the dilating tip, the first electrode having an annular shape and being positioned on the neck and abutting the distal-facing shoulder surface;
- and an electrical conductor electrically connected to the first electrode and extending proximally from the first electrode to the proximal end portion;
- and
- an electroanatomical mapping system electrically connectable to the electrical conductor and configured to receive an electroanatomical mapping signal from the first electrode and determine a location of the dilating tip based on the electroanatomical mapping signal.
