    摘要： Methods and apparatus are disclosed for filling a therapeutic substance or drug within a hollow wire that forms a stent. The stent is placed within a chamber housing a fluid drug formulation. During filling, the chamber is maintained at or near the vapor-liquid equilibrium of the solvent of the fluid drug formulation. To fill the stent, a portion of the stent is placed into contact with the fluid drug formulation until a lumenal space defined by the hollow wire is filled with the fluid drug formulation via capillary action. After filling is complete, the stent is retracted such that the stent is no longer in contact with the fluid drug formulation. The solvent vapor pressure within the chamber is reduced to evaporate a solvent of the fluid drug formulation. A wicking means may control transfer of the fluid drug formulation into the stent.

    摘要： An intraluminal stent, an intraluminal stent delivery system, and a method of treating a vascular condition. The stent includes a framework composed of a biodegradable material. At least one strut is composed of a non-biodegradable material. The framework is operably attached to the at least one strut. The delivery system includes a catheter and a stent disposed on a portion of the catheter. The stent includes a framework composed of a biodegradable material. The stent further includes at least one strut composed of a non-biodegradable material. The framework is operably attached to the at least one strut. The method includes positioning an intraluminal stent via a catheter within a vessel. The stent includes at least one strut that is composed of a non-biodegradable material and is operably attached to a framework. The framework expands during deployment of the intraluminal stent. The framework is allowed to biodegrade within the vessel.

    摘要： A guide catheter assembly includes a dilator (150) and a guide catheter (110). The dilator includes a dilator lumen (156) extending from a distal opening (153) at a distal end to a proximal opening (156) at a proximal end, and a side exit port (158) proximal of the distal opening and in communication with the dilator lumen. The guide catheter includes a proximal end, a distal end, and a guide lumen extending therebetween. The dilator and the guide lumen are sized such that the dilator can pass through the guide lumen. The dilator and the guide catheter are sized such that with the proximal end of the dilator generally aligned along an axis with the proximal end of the guide catheter, the distal end of the dilator extends distally past the distal end of the guide catheter and the side exit port is disposed distal of the distal end of the guide catheter.

    摘要： The coil stent delivery system and method of use includes a stent delivery system including a coil stent; a housing, the housing having a receiver defining a receiver chamber and a sheath defining a sheath lumen, the receiver chamber being in communication with the sheath lumen; and a screw assembly, the screw assembly having a shaft, a helical screw disposed about a distal portion of the shaft, and a drive operably coupled to the shaft. The shaft is disposed in the receiver chamber and the sheath lumen, the helical screw is disposed in the sheath, and the coil stent is disposed about the shaft in the receiver chamber and engages the helical screw. Rotation of the drive moves the coil stent through the sheath lumen.
