Title:	Vancomycin haemostatic paste composition
Abstract:	A haemostatic paste composition comprising powdered vancomycin mixed with a biocompatible carrier. The haemostatic paste composition is easily handled, adheres to a cut bone surface or an exposed bone surface, provides for effective haemostasis to prevent blood loss from a cut bone surface or an exposed bone surface, has no systemic or local adverse effect and provides bacteriostatic and bacteriocidal protection. The haemostatic paste composition is well suited for use with sternotomy incisions, but can also be used for any cut bone surface or exposed bone surface during surgery.

Application Number:	10/758,548
Patent Claims:	1. A haemostatic composition consisting of: a quantity of powdered vancomycin homogenized with a quantity of biocompatible carrier to form a paste for use on a cut bone surface or an exposed bone surface, the paste and the quantity of biocompatible carrier is in a ratio of 1 to 1, gram weight to cubic centimeter volume, the quantity of powdered vancomycin provides an effective amount of haemostasis and provides antibacterial protection against gram-positive bacteria. 2. The haemostatic composition of claim 1, wherein the quantity of biocompatible carrier is selected from the group consisting of sterile water, aqueous saline solution and Lactated Ringers. 3. The haemostatic composition of claim 1, wherein the paste has a spreadable consistency and adheres to the cut bone surface or the exposed bone surface. 4. A haemostatic composition consisting of: An admixture of a quantity of powdered vancomycin and a quantity of biocompatible carrier for use on a cut bone surface or an exposed bone surface, the ratio of the quantity of powdered vancomycin to the quantity of biocompatible carrier is 1 to 1, gram weight to cubic centimeter volume, the admixture provides an effective amount of haemostasis and provides antibacterial protection against gram-positive bacteria, the quantity of biocompatible carrier being selected from the group consisting of sterile water, aqueous saline solution and Lactated Ringers. 5. The haemostatic composition of claim 4, wherein the admixture forms a paste, the paste having a spreadable consistency and adheres to the cut bone surface or the exposed bone surface. 6. A haemostatic composition consisting of: a quantity of powdered vancomycin homogenized with a quantity of biocompatible carrier to form a paste for use on a cut bone surface or an exposed bone surface, the paste having a spreadable consistency and adheres to the cut bone surface or the exposed bone surface to provide an effective amount of haemostasis, the quantity of powdered vancomycin additionally providing antibacterial protection against gram-positive bacteria, the quantity of powdered vancomycin and the quantity of biocompatible carrier being in a ratio of 1 to 1, gram weight to cubic centimeter volume. 7. The haemostatic composition of claim 6, wherein the quantity of biocompatible carrier is selected from the group consisting of sterile water, aqueous saline solution and Lactated Ringers.
