Abstract
A method is provided for accessing a pericardial space of a subject. The method includes advancing a guide member toward a heart, having (a) a transparent blunt distal end, and (b) a side-facing suction port. During advancing of the guide member, an imaging device disposed in the guide member generates an image of part of the heart. Subsequently to contacting the pericardium with the suction port, the imaging device is retracted proximally in the guide member. Subsequently, a portion of the pericardium is drawn into the guide member through the suction port. Following the drawing of the portion into the guide member, an image of the pericardium disposed within the suction port, is generated. Subsequently, a puncturing element is advanced in the guide member to puncture the portion of the pericardium that is in the guide member. Other applications are also described.
