1. An anastomosis connector;
- comprising;
a plurality of ring segments, together defining a radially expandable ring-like shape having a lumen;
at least one pivot bar coupled to at least one of said ring segments; and
at least one spike mounted on said pivot bar and rotatable around said pivot bar,wherein radial deformation of said ring-like shape does not substantially directly affect said spike rotational position.

Abstract
An anastomosis connector comprises a plurality of ring segments (106), together defining a radially expandable ring-like shape (106) having a lumen; at least one pivot bar (114) coupled to at least one of said ring segments (106); at least one spike (109) mounted on said pivot bar (114) and rotatable around said pivot bar (114), wherein radial deformation of said ring-like shape (106) does not substantially directly affect said spike (109) rotational position.

64. Apparatus for graft eversion of a graft over a shaft having a tip, comprising:
-
a handle for engaging said shaft; a plurality of forceps arranged to engage a tip of said graft where it protrudes form said shaft; and a plurality of joints, each one associated with one of said forceps, for rotating said forceps pulling a tip of each of said forceps axially along said shaft.

65. A method of measuring a graft size, comprising:
-
mounting a tip of said graft on two extensions, one extension coupled to a spring and one extension coupled to a handle; manipulating said handle such that said extensions separate; reading a measurement on a scale coupled to said spring; and selecting an anastomosis connector responsive to said read measurement. - View Dependent Claims (66)

67. A hole puncher, comprising:
-
a sharp tip for forming a puncture in a blood vessel; a shaft having a varying diameter and having a depression formed therein for engaging a wall of said blood vessel, said diameter substantially matching a diameter of said tip at one end of the shaft, said diameter increasing away from said tip for a first distance and said diameter then defining a slope of diminishing diameter towards said depression; and an outer tube mounted on said shaft and having an end, said outer tube having an inner diameter of said end that is in a range of diameters defined by said slope of diminishing diameters. - View Dependent Claims (68, 69)
