    摘要： An apparatus for capturing material within a body lumen includes a shaft carrying an expandable basket device on a distal end thereof. The basket device includes a distal basket carried and a proximal basket carried on the shaft such that the proximal basket is proximal to and spaced apart from the distal basket. Each basket includes an open end communicating with an interior of the respective basket and oriented towards one another. In one embodiment, a tubular middle portion extends between the baskets. In another embodiment, the distal basket includes an actuator coupled to the distal basket open end such that movement of the baskets towards one another causes the actuator to direct the distal basket open end inwardly to allow the open end to be received within the proximal basket to facilitate removal of the apparatus after capturing material within the baskets.

    摘要： Enhanced dual purpose systems enable dilating of at least a lesion within a blood vessel and providing an anti-proliferative medicament in a non-attached form directly into the lumen of the vessel. Likewise provided is the ability to stop blood flow to prevent wash-out of the medicament during dwell time within the body lumen, and the ability to remove the medicament after the dwell time of the device to prevent unwanted exposure of the same within the body.

    摘要： Apparatus and methods are provided for treating a lesion within a body lumen using a catheter including a balloon on its distal end that includes a plurality of raised structures that extend outwardly from the balloon membrane. In one embodiment, the raised structures are provided in pairs that are spaced apart from one another about the circumference of the balloon, and each pair includes two raised structures that are spaced relatively closely together compared to the distance the two raised structures are spaced apart from adjacent pairs. Optionally, the membrane between the two raised structures of each pair may be relatively thinner than the membrane between spaced apart pairs such that the distance between the raised structures in each pair increases as the balloon is expanded within a lesion.

    摘要翻译： 提供了用于使用包括其远端上的气囊的导管来治疗体腔内的损伤的装置和方法，该导管包括从气囊膜向外延伸的多个凸起结构。 在一个实施例中，凸起结构成对设置，围绕球囊的圆周彼此间隔开，并且每对包括与两个凸起结构间隔开的距离相对靠近地间隔开的两个凸起结构 相邻对。 任选地，每对的两个凸起结构之间的膜可以比间隔开的对之间的膜相对薄，使得当气囊在损伤内扩张时，每对中的凸起结构之间的距离增加。
