Claims5
A vessel connector or occluder that comprises an elongate cylindrical member having an external cylindrical surface of a predetermined diameter and having first and second spaced apart ends, and connector means on the first end for connection to a tube or blood vessel or vein, said connector means comprising a tip portion of substantially the same diameter as said predetermined diameter and, spaced closely adjacent said tip portion, a plurality of circumferential flanges of different diameters spaced a short distance apart from each other, said flanges being configured, dimensioned and constructed such that the largest diameter flange lies immediately adjacent the tip portion and the smallest diameter flange lies more distant from the tip portion than the largest diameter flange, said flanges being configured, dimensioned and constructed such that the diameters of the flanges are larger than the diameter of said closely adjacent tip portion.
A cannula-to-vessel connector or occluder that comprises an elongate cannula having a first external cylindrical surface of a first predetermined diameter a first end, a second external cylindrical surface of a second predetermined diameter a second end, and connector means on said first end for connection to a tube or blood vessel or vein, said connector means comprising a tip portion of substantially the same diameter as said predetermined diameter and, spaced closely adjacent said tip portion, a plurality of circumferential flanges of different diameters spaced a short distance apart from each other, said flanges being configured, dimensioned and constructed such that the largest diameter flange lies immediately adjacent the tip portion and the smallest diameter flange lies more distant from the tip portion than the largest diameter flange, said flanges being configured, dimensioned and constructed such that the diameters of the flanges are larger than the diameter of said closely adjacent tip portion.
