    摘要： Bioresorbable stents for treating airway disorders and methods of treatment of the airway disorders using the bioresorbable stents are disclosed. Once implanted, the stents stabilize or maintain an airway lumen. The radial strength of the stents decreases with time which allows the airway to adjust from being artificially supported to a healed state without artificial support. The stent may be removed from the airway through bioresorption without intervention. The bioresorbable stents include a bioresorbable body having a shape that conforms or is conformable to the shape of the of airway lumen.

    摘要： Balloon catheter includes an outer shaft including a hypotube and a monolithic multilayer distal outer member and having an inflation lumen defined therethrough, a balloon in fluid communication with the inflation lumen, and an inner tubular member having a guidewire lumen defined therethrough. The monolithic multilayer distal outer member has a proximal end portion and a distal end portion. The monolithic multilayer distal outer member has an inner layer comprising a first polymer having a tensile strength greater than about 8,000 psi and an outer layer comprising a second polymer having a flexural modulus of less than about 130,000 psi at room temperature. A proximal end of the monolithic multilayer distal outer member is coupled to the hypotube. The monolithic multilayer distal outer member is necked to a reduced diameter along at least a portion of a length thereof. The balloon has a proximal balloon shaft coupled to a distal end of the monolithic multilayer distal outer member. The inner tubular member extends distally from a proximal port in the proximal end portion of the monolithic multilayer distal outer member through at least a portion of the balloon.
