  • Publication number: 20080077178
    Abstract: A device is proposed for inserting hemostatic material through a tissue channel and against the wall of a blood vessel of a patient, wherein the blood vessel wall has a puncture therein adjacent the tissue channel. The device includes a charge of hemostatic material and a hollow sheath adapted to pass through the tissue channel, the sheath having a cross sectional profile larger than the puncture. The device places the hemostatic material in the hollow sheath and advances the hemostatic material through the sheath to the vessel wall around the puncture.

  • Patent number: 5028695
    Abstract: The invention concerns a process for the manufacture of collagen membranes for medical applications, in which process the collagen raw materials obtained from cattle or pig collagen are mechanically freed of fatty residues and treated with diluted alkali and acids and, if need be, enzymes. It is thoroughly washed between these steps to thus clean the collagen raw material eliminating the accompanying contamination. It is then processed further while obtaining a collagen matrix with a dry weight of approximately 25% by weight. Thus obtained are collagen membranes, in which the original integral cohesion remains and with which a fast hemostatic effect is achieved; said membranes are also extremely flexible and they adhere well to the surface of a wound.
