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 electroanatomical mapping system.

Abstract: Methods and apparatus are disclosed for puncturing tissue, including a surgical introducer with a stiff main body and a flexible tip which can be used with a puncture device to gain epicardial access. The surgical introducer comprises an introducer shaft having a rigid portion and a flexible tip portion. The rigid portion has a metal tube extending to the rigid portion distal end. The flexible tip portion is distal of the metal tube distal end. The flexible tip portion includes a first polymer and a second polymer, wherein the second polymer is more flexible than the first polymer. The second polymer extends distally from the metal tube distal end to define a second polymer flexible tip segment. The first polymer extends distally from the second polymer flexible tip segment end to define a flexible tip portion cap.

Abstract: A method and apparatus are disclosed for a needle for gaining access to the pericardial cavity of a heart. The needle includes an elongate member (e.g. a main shaft) defining a lumen and a side-port in fluid communication with the lumen; a blunt atraumatic tip for delivering energy for puncturing tissue; and a guiding surface (e.g. a ramp) for directing a device (e.g. a guidewire) through the side-port. The method includes using the needle for tenting a pericardium and delivering energy for puncturing the pericardium, and advancing a guidewire or other device through the needle and into the pericardial cavity.
