Abstract
Apparatus and methods are described including a trocar (40) that defines a lumen therethrough, configured to provide a passage through skin of a subject into a body of the subject. A cannula (60) is configured to be placed into the subject'"'"'s body via the passage provided by the trocar, the cannula being configured to be slidable with respect to the trocar. The cannula includes an outer tube (64) having a first expandable element (77) disposed at a distal end thereof, and an inner tube (62) having a second expandable element (72) disposed at a distal end thereof, the inner tube being configured to be slidable with respect to the outer tube. A vacuum port (61) applied vacuum pressure to the first expandable element via a space (65) between the inner and outer tubes of the cannula. Other applications are also described.

14. Apparatus for use with an insertion device, the apparatus comprising a closure device, the closure device comprising:
-
a plug portion configured to be placed within a passage in a wall of a heart of a subject by being introduced to the passage via the insertion device, the insertion device being configured to maintain the plug portion in a constrained state thereof during the insertion, the plug portion being configured to automatically increase a radius of the plug portion by more than 0.5 percent by assuming a non-constrained state thereof by being pushed out of a distal end of the insertion device; an intracardiac portion, coupled to the plug portion, and configured for placement within a heart chamber; and an extracardiac portion coupled to the plug portion and configured for placement outside of the heart chamber. - View Dependent Claims (15, 16, 17, 18, 19, 20, 23, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 118)
