An anastomosis apparatus includes a first rigid element (10), and a second rigid element (20). The first element defines a first passageway or lumen which extends along its entire length. In construction the first element includes a first tubular portion in association with a first flange (12) disposed on one end of the first tubular portion. The first flange (12) is fixedly secured to the first tubular portion (11). The second element define s a second passageway along its entire length which is dimensioned to sliding receive, and retain the first tubular portion. The second element (20) includes a second tubular portion (21) in association with a second flange (22) disposed on a proximal end of the second tubular portion. An engagement of the first element with the second element about an opening defined in the blood vessel of a patient results in a fixed spatial relationship of the fir st element relative to the second element, whereby the first passageway is retained in a generally fixed spatial relationship with the lumen of the aforesaid blood vessel.
