Abstract
A device, whose purpose is such internal shielding of a vascular anastomosis that undesirable perivascular vibration is avoided, is created from a stiff or possibly moderately elastic, non-resorbable, biologically inert, non-moistenable and sterilizable material. The shield has the form of an incomplete tube (4), whose length is at least five times larger than the diameter of the targeted vessel or substitute. This incomplete tube (4) in the third and fourth fifths of its length (counting counter to the course of blood flow) is provided with an orifice (5) having a width of at least one quarter of the circumference of the tube. From the apical end of the orifice (5) and/or from the rear end of the said orifice (5) projects a gradually tapered tongue-shaped structure (6, 10) which is moderately bow-curved externally. The margin (8) of the orifice (5) and all margins of the device are blunt, and the whole internal surface of the device is highly polished.
