  • Publication number: 20140257275
    Abstract: A method of creating a thermochromic artificial blood vessel includes physically cross-linking a polyvinyl alcohol solution in a mold shaped to mimic a blood vessel to create an artificial blood vessel. The artificial tissue is then chemically cross-linked with a solution including a chemical cross-linking reagent. A coagulation solution is then applied to the artificial blood vessel to both inhibit the chemical cross-linking and promote physical cross-linking of the artificial blood vessel. The artificial blood vessel can be used to test an ablation catheter. The vessel, when heated by the ablation catheter, changes color and/or transparency at locations where the temperature of artificial blood vessel increases.

  • Publication number: 20140243969
    Abstract: A prosthetic heart valve includes a valve assembly mounted to an expandable stent. The prosthetic heart valve includes a cuff coupled to the stent. The cuff includes a pocket formed between an outer side and an inner side of the cuff. The pocket includes a plurality of biocompatible and irreversibly expandable microspheres. After implantation of the prosthetic heart valve into a patient, any gaps existing between the cuff and the native heart valve are exposed to bodily fluid, such as blood. The blood enters the pocket of the cuff through pores in the outer side of the cuff. The blood interacts with the microspheres, causing irreversible expansion of the microspheres. The microspheres expand to fill any gaps between the prosthetic heart valve and the native heart tissue, sealing the gaps and preventing leakage through the gaps.
