Publication number: 20240058125Abstract: A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached, includes a shaft assembly including a distal end and a coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve. The system includes a sheath assembly defining a lumen sized to slidably receive the shaft assembly. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve. The coupling structure is configured to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve based on longitudinal movement of the distal end of the shaft assembly.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Inventors: Matthew Rust, Padraig Savage, Gianfranco Pellegrini, Finn Rinne

Publication number: 20120198878Abstract: The present invention relates to a heating device with irreversible thermodynamic cycle. The device comprises a low temperature circuit and a high temperature circuit in which respectively a first and a second operating fluid circulate. Each circuit comprises evaporating, compression, condensation and expansion means of the respective operating fluid. The low temperature circuit absorbs thermal energy from a supply water flow for evaporating the first operating fluid. The thermal energy deriving from the condensation of the first operating fluid is used for evaporating the second fluid. Instead, the thermal energy deriving from the condensation of the second fluid is used for heating a delivery water flow. According to the invention, the two operating circuits each comprise cooling means interposed between the corresponding condensation and expansion means.Type: ApplicationFiled: October 13, 2010Publication date: August 9, 2012Applicant: INNOVATION FACTORY S.R.L.Inventor: Gianfranco Pellegrini
