Adhesive medical product for surgical fastening devices
A recently granted patent (Publication Number: US11992577B2) discloses a medical product that includes a medical graft material with an adhesive containing chondroitin sulfate, carboxymethyl cellulose, sorbitol, and maltitol. The patent specifies various ratios for the components in the adhesive, such as the dry weight ratio of carboxymethyl cellulose and chondroitin sulfate ranging from 10:1 to 1:3, and the dry weight ratio of sorbitol and maltitol ranging from 10:1 to 1:1. Additionally, the adhesive may include sodium chloride in specific dry weight ratios with sorbitol. The medical graft material is packaged in a sterile package designed to maintain a humidity level of 50-65% relative humidity.
Furthermore, the patent also covers a medical adhesive formulation comprising carboxyalkyl cellulose, sorbitol, maltitol, a sulfated glycosaminoglycan, and a salt. The ratios of sorbitol and maltitol in this adhesive range from 10:1 to 1:1 in dry weight. The specific components like carboxymethyl cellulose, chondroitin sulfate, and sodium chloride are present in defined dry weight ratios in the adhesive. The moisture content of the adhesive is specified to be between 5% to 15%. Another variation of the medical adhesive includes a combination of carboxyalkyl cellulose, a sugar alcohol, and either a sulfated glycosaminoglycan or a crystallization inhibiting salt. The ratios of carboxymethyl cellulose and chondroitin sulfate, as well as sorbitol and maltitol, are detailed in the patent, along with the presence of sodium chloride as a crystallization inhibiting salt in specific dry weight ratios with sorbitol.
