摘要： A method of a forming a hollow, drug-eluting medical device includes providing composite member having an outer member and a core member disposed within a lumen of the outer member. The composite member is shaped into a pattern. Openings are formed through the outer member of the composite member. The composite member is processed to remove the core member from the lumen of the outer member without harming the outer member, leaving a hollow tubular member already formed into the desired pattern. The lumen of the outer member is filled with a therapeutic substance.

摘要： Artificial valves for use as a venous valve or a heart valve are disclosed. The valve includes a frame including a platform and a valve material coupled to the frame. The valve material is a plurality of filaments or a flap. The valve material is coupled to the frame such that in response to a force in a first direction, e.g. blood flow, the valve material extends in the direct of the force to allow blood to flow past the valve material. In absence of the force in the first direction, the valve material rests against the platform to block blood flow in a direction opposite the first direction.

摘要： An obstruction removal system (100) for percutaneous removal of clots or obstructions within the vascular system is disclosed. The obstruction removal system (100) includes a multi-lumen catheter (102) with a plurality of circulating capture devices (114) attached to or integral with a drive belt (112). The circulating capture or interference devices (114) affect removal of the clot or obstruction bit-by-bit through a series of passes. The obstruction removal system (100) may include one or more drive mechanisms (116), such as a pulley system and/or a vacuum source and/or a pressurization source, on its proximal end for driving the drive belt (112) and capture devices (114) through the catheter (102) in a circulating manner. The obstruction removal system (100) may also include one or more cleaning mechanisms, such as a vacuum chamber and/or a fluid rinse chamber, for removing the captured clot pieces from the capture devices (114).

摘要： Devices and methods for limiting the depth to which a penetrator is advanced into an organ or mass of tissue. The device generally comprises a first member and a second member. The penetrator is attached to and extends from a second member. The first member has a penetrator shroud and a hollow bore extending therethrough. The second member is engageable with the first member such that a distal portion of the penetrator extends through the penetrator shroud. The distance to which the penetrator protrudes out of and beyond the distal end of the penetrator shroud is adjustable in accordance with the desired depth of penetration. The penetrator may then be advanced into the organ or tissue mass until the distal end of the shroud abuts against the organ or tissue mass, thereby stopping further advancement of the penetrator. The penetrator may have one or more lumen(s) for aspirating or infusing substances.
摘要翻译：用于限制穿透器进入器官或组织块的深度的装置和方法。该装置通常包括第一构件和第二构件。穿透器附接到第二构件并从第二构件延伸。第一构件具有穿透器护罩和延伸穿过其中的中空孔。第二构件可与第一构件接合，使得穿透器的远端部分延伸穿过穿透器护罩。穿透器突出到穿透器护罩的远端之外的距离可以根据期望的穿透深度进行调节。然后穿透器可以推进到器官或组织块中，直到护罩的远端抵靠器官或组织块，从而停止穿透器的进一步前进。穿透器可以具有用于吸入或输注物质的一个或多个内腔。

摘要： Devices and methods for simultaneous injection or delivery of two or more substances from separate syringes. The syringes are loaded into a device that has a handle and a screw driven mechanism for simultaneously depressing the plungers of the syringes. The user grasps the handle and positions the device. Thereafter, the screw mechanism is used to simultaneously advance the plungers of the syringes thereby simultaneously expelling the substances from the syringes.

摘要： The matched end stiffness stent system and method of manufacture includes a stent delivery system including a catheter, balloon, and stent. The stent (120) includes a wire (122) bent into a waveform having a constant frequency and wrapped into a hollow cylindrical shape, the wire having a body portion (124) having body struts (126) connected between body crowns (128), the body struts having substantially equal lengths, and the waveform in the body portion having a constant amplitude; and at least one end portion (130) attached to the body portion, the at least one end portion having end struts (132) connected between end crowns (134), the waveform in the at least one end portion having an amplitude different from the constant amplitude of the waveform in the body portion. The cross sections of the end struts are selected so that the body struts and the end struts have a substantially equal stiffnesses in response to an applied load.
