    摘要: A catheter for use in vasculature or other lumen within body structures includes a shaft formed from an elongated polymeric flexible tube. A metallic tube may be bound to the distal end of this tube. A thinner, more flexible tube may be attached to the distal end of a metallic tube. The two plastic tubes, together with any metallic tube define a lumen for providing communication with an angioplasty balloon or with a body lumen at the distal end of the catheter. A catheter may include a core member to facilitate moving the catheter through a lumen, and to reduce the likelihood that the catheter will kink or bend improperly. This metallic core member extends from the hub to some point distal on the catheter, and may extend to the distal tip of the catheter. The distal end of a catheter balloon may be secured to the core member during manufacture of the catheter. The core member has a zigzagged or helix shape at the proximal end which is friction fit into the hub lumen, and may have a pointed tip that embeds in the hub inner wall. During manufacture, the core member can be secured within the hub with reduced reliance on adhesives or molding of the core member within the hub body. The core member may be secured within the hub by being press fit into the hub lumen. The catheter is more easily manufactured, and has an increased volume and reduced obstruction by adhesive in comparison with other methods of securing the core member.

    摘要: A stent for delivering therapeutic agents to a body lumen includes a plurality of circumferential serpentine bands with each band comprising a plurality of struts. At least one strut has at least one first well region and at least one second well region. The at least one first well region has a first thickness, the at least one second well region has a second thickness, the first thickness being greater than the second thickness. Each well region defines a well having a depth. At least some of the wells contain a therapeutic agent.

    摘要: A stent comprises a plurality of serpentine bands. Each serpentine band has alternating peak regions and trough regions and extends about substantially the entire circumference of the stent. At least one of the serpentine bands has a spline extending therefrom toward a serpentine band adjacent thereto. Serpentine bands which are adjacent one another are connected one to the other.

    摘要: A stent with strut bands and connectors, wherein the strut bands have long and short struts with a junction positioned between the short struts. Each junction defines a reservoir, wherein the reservoirs of a strut band are substantially circumferentially aligned. The connectors each have arms, wherein each arm includes an opposing U-shaped link. The opposing links have a shared portion disposed between a peak on one strut band and a longitudinally adjacent trough of an adjacent strut band.
