    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.

    Abstract: Embodiments of medical devices and methods are disclosed. The medical devices typically comprise a flexible elongate member defining a lumen, and a support spine affixed to the distal end and extending proximally therefrom within the elongate member lumen. In some embodiments, the support spine is pre-shaped such that the support spine biases the distal region of the elongate member to adopt a straight configuration, or the support spine biases at least a portion of the distal region of the elongate member to adopt a curved shape to form a curved portion. Some embodiments include apertures at or near the distal end for enabling fluid communication between the lumen and the outside environment. In some embodiments, the support wire extends proximally from the distal end within a distal portion of the lumen such that a proximal portion of the lumen is substantially unobstructed.
