PERICARDIAL ACCESS DEVICE

摘要

Apparatus (120) is provided comprising: a longitudinal guide member (220) (a) comprising a blunt distal end (160) having an outer surface (164) at least part of which is transparent, (b) configured to be advanced distally toward a heart of a subject, and (c) shaped to define an at least partially distally-facing and side-facing suction port (660) at a distal portion (662) of the longitudinal guide member (220). The apparatus is configured to facilitate drawing a portion of a pericardium of the heart through the suction port and into the longitudinal guide member. The apparatus additionally comprises a puncturing element (50) configured to puncture the portion of the pericardium while the portion of the pericardium is in the longitudinal guide member. Other applications are also described.

1. Apparatus comprising:
a longitudinal guide member (a) comprising a blunt distal end having an outer surface at least part of which is transparent, and (b) configured to be advanced distally toward a heart of a subject; a sheath shaped and sized to surround the guide member and shaped to define an at least partially distally-facing suction port at a distal end of the sheath, the apparatus being configured to facilitate drawing a portion of a pericardium of the heart through the suction port and into the sheath, when the suction port is distal to the guide member; a puncturing element configured to puncture the portion of the pericardium while the portion of the pericardium is in the sheath; and a puncturing-element-restraining element shaped and positioned with respect to the puncturing element to inhibit passage of a distal tip of the puncturing element out of the distal end of the sheath.
