1. A device configured to enter a wall of a blood vessel, the device comprising:
a first sheath having a proximal end, a distal end, and a hinge along its length with an aperture at the hinge;
a cap coupled to the distal end of the first sheath;
a tether filament coupled to the cap and extending proximally along the first sheath external to the first sheath and translatable along the first sheath to cause the first sheath to bend along the hinge to selectively move the aperture between a closed configuration and an open configuration;
a wire slidable within the first sheath and having a distal end configured to extend through the aperture toward the wall of the blood vessel, when the first sheath is bent, to form a hole through the wall of the blood vessel, and to extend into the pericardial cavity of the heart.
