1. A cardiovascular surgical apparatus comprising:
a sleeve including a distal sleeve end, a proximal sleeve end, and a sleeve long axis extending from the distal sleeve end to the proximal sleeve end; a post including a distal post end and a proximal post end; a first projection member, coupled to the distal sleeve end, including a first projection member main body and a first projection member retention body; a second projection member coupled to the distal post end; wherein (a) the first and second projection members both project outwards and away from the sleeve long axis; (b) the post telescopes distally from within the sleeve and away from the distal sleeve end; (c) at least one of the first and second projection members rotates at least 45 degrees about the sleeve long axis and with respect to another of the first and second projection members; and (d) the first projection member retention body includes a long axis generally parallel to the sleeve long axis.
