    摘要： Device for treating mitral insufficiency and a method for producing the device. The device comprises a proximal stent section (222); a distal stent section (224); a central stent section (226) interconnecting said proximal stent section (222) and said distal stent section (226); and at least one biodegradable structure (228), disposed on the central stent section (226). Said proximal stent section (222) and said distal stent section (226) being radially expandable by deployment of said device. Moreover said biodegradable structure (228) is arranged to retain the central section (226) in a contracted shape for a predetermined period after deployment of the device.

    摘要： A prosthetic lung for receipt by a lung space of a patient includes a mass exchange apparatus for use in blood/air mass exchange, an air sac and an air vessel. The mass exchange includes plural blood flow conduits for defining blood flow and a plural air flow conduits for defining air flow. The plural air flow conduits and the plural blood flow conduits at least partially include gas-permeable membrane material and the conduits are arranged relative to each other to enable transfer of oxygen from the air to the blood and transfer of carbon dioxide from the blood to the air. The mass exchange apparatus is provided with at least one first air port and at least one second air port, so that the air flow may be defined therebetween by the plural air flow conduits. The air sac defines an air sac cavity in fluid communication with at least one first air port of the mass exchange apparatus. The air vessel defines an air vessel cavity in fluid communication with at least one second air port of the mass exchange apparatus. The air vessel is provided with an air access port arranged, in use, to enable air flow communication with the trachea of the patient.

    摘要： A biodegradable double stent is used for various organs such as a biliary tract, an esophagus, an airway and a ureter. A biodegradable stent having a hollow cylindrical body woven out of a separate wire made of biodegradable polymer so as to have a plurality of rhombic spaces is fixed to an intermediate portion of a primary stent having a cylindrical body. When administered into the organ, the biodegradable stent has its original function of expanding the organ, and is firmly supported in the inner wall of a narrowed passage of the organ by pressurizing the inner wall of the narrowed passage of the organ. After a predetermined time period has elapsed, the biodegradable stent is gradually degraded away by bodily fluids, thereby enabling the primary stent to be easily removed from the organ.

    摘要： An air passageway obstruction device (80,130,160) includes a frame structure (86,132,134,162,164,166) and a flexible membrane (112,150,186) overlying the frame structure. The frame structure (86,132,134,162,164,166) is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and recollapsible upon removal from the air passageway. The flexible membrane (112,150,186) obstructs inhaled air flow into a lung portion communicating with the air passageway. The device (80,130,160) may be removed after deployment in an air passageway by recollapsing the device and pulling the device proximally through a catheter (70).
