Nerve Repair Using Laser Sealing

The present invention provides a method of nerve repair using localized delivery of heat. The method involves localized induction of hyperthermia for end-to-end attachment of severed peripheral nerves by delivering stimulus responsive materials and exposing them to an excitation source under conditions wherein they emit heat. The generation of heat effects the joining of the nerve ends.

RAM Hashing in Blockchain Environments

Blockchain environments may mix-and-match different encryption, difficulty, and/or proof-of-work schemes when mining blockchain transactions. Each encryption, difficulty, and/or proof-of-work scheme may be separate, stand-alone programs, files, or third-party services. Blockchain miners may be agnostic to a particular coin's or network's encryption, difficulty, and/or proof-of-work schemes, thus allowing any blockchain miner to process or mine data in multiple blockchains. GPUs, ASICs, and other specialized processing hardware components may be deterred by forcing cache misses, cache latencies, and processor stalls. Hashing, difficulty, and/or proof-of-work schemes require less programming code, consume less storage space/usage in bytes, and execute faster. Blockchain mining schemes may further randomize byte or memory block access, further improve cryptographic security.

COLORED BIOLOGIC WOUND TREATMENT PROVIDING HEALING PROGRESS MONITORING
20220313873 · 2022-10-06 ·

Tissue-regenerating wound treatments, methods of producing tissue-regenerating wound treatments, and methods of treating a wound using a tissue-regenerating wound treatment are provided. The tissue-regenerating wound treatment includes a skin substitute and a coloring agent added to the skin substitute. The coloring agent is a biocompatible coloring agent that degrades upon protease attack within a treated wound.

METHODS FOR TISSUE PASSIVATION

One aspect of the invention provides a method of preventing or reducing stenosis in a subject. The method includes implanting a passivated graft comprising vein into an artery. The implanting of the graft replaces and/or bypasses a diseased segment of the artery. The passivated grail including vein is prepared by exposing the exterior surface of the passivated graft comprising vein to a tissue structure stabilizing agent (“TSSA”) under conditions sufficient to promote cross-linking of proteins within the vein.

Surface-modified polymeric substrates grafted with a properties-imparting compound using clip chemistry

The present invention relates to an efficient method for grafting a properties-imparting compound onto a polymeric substrate containing carbon-hydrogen (C—H) bonds using clip chemistry. The method of the invention includes coating the substrate with the properties-imparting compound and irradiating it with a reactive light source, and repeating this sequence at least once. The present invention further relates to surface-modified polymeric substrates grafted with a properties-imparting compound, in particular obtained with the method of the invention, medical devices comprising same, and non-medical of said surface-modified polymeric substrates.

CONTROLLED HEAT DELIVERY COMPOSITIONS

The disclosure describes a heat delivery medium and composition for biomedical applications with controlled conversion of energy from an exogenous source to heat.

Method for Treating Tissue

Methods for treating tissue are provided. In one embodiment, an adjunct material, when secured to tissue, can receive at least one physiological element released from the tissue during healing progression of the tissue, and can exhibit first and second stiffnesses in compression that are approximately constant during first and second time periods from contact with the tissue, with the second stiffness decreasing with time as a function of at least one of oxidation, enzyme-catalyzed hydrolysis, and change of pH resulting from interaction with the at least one physiological element. In another embodiment, the adjunct can receive a unit volume of fluid that causes first and second portions of the adjunct to expand according to first and second expansion behaviors that differ from one another to apply different pressures to the tissue.
