ABSTRACT:
A device for non-surgical sealing of the interstice in the wall of a vessel is provided. The device includes a tubular, resorbable collagen plug 4 having longitudinal cut 8 in the form of a V. The device can further include applicator 5. The opening of cut 8 of plug 4 is located on the peripheral portion of plug 4. The internal diameter of plug 4 corresponds to the external diameter of catheter 3 which is introduced into vessel 1. The external diameter of plug 4 corresponds to the external diameter of applicator 5. Plug 4 includes inner and outer layers of resorbable collagen which have differing swelling rates. Applicator 5 includes longitudinal cut 10 in the form of a V. The opening of cut 10 is located on the peripheral side of applicator 5 relative to vessel 1.
