摘要:
This invention is a method and composition for inhibiting restenosis. The composition (64) includes an adhesive or polymeric material having a radioactive component dispersed therethrough. The biologically compatible adhesive (64) including a radioactive material, is applied to a vessel region where inhibition of restenosis is desired.
摘要:
The catheter comprises a catheter tube 1 formed of two superposed tubular layers of materials 2 and 3 which differ from one another. A tubular mediator layer 4 is arranged between layers 2 and 3 to provide an adhesive anchorage for layers 2 and 3.
摘要:
The stent delivery device comprises an elongated sheath (2) with a self-expandable stent (7) placed in contracted condition within the distal area (3) of the sheath (2). An elongated core (5) is arranged in the sheath (2) for relative longitudinal motion between core and sheath, and drive means (13) are arranged between the core (5) and the stent (7). Scratch protection tubular means (16) comprise a reinforcement ring (18) secured in the sheath (2) and surrounding the distal end portion (79) of the stent when the stent is in contracted condition in the sheath and a tube of thermoformable material (37) heat shrunk over the proximal end portion (78) of the stent and over the core (5).
摘要:
An interventional catheter for angioplasty and the like, comprising a catheter tube (1) formed of two superposed layers 3 and 4 of materials different from one another. Over the distal end 2 of the catheter tube 1 is positioned a balloon 6 with a distal neck 7 sealingly surrounding the outer layer 4 of the catheter tube. A tip 8 is formed by a piece of material 12 welded to the distal end 2 of the catheter tube and the distal neck 7 of the balloon 6 also welds to the proximal portion 9 of the tip 8.
摘要:
The guide wire comprises an elongated flexible shaft 2 which is tubular. A helical coil assembly 4 of radiopaque material comprises a first coil 5 having a proximal portion 6 threadedly force fitted into the tubular portion 3 of shaft 2. A second coil 8 has a proximal portion 9 surrounding and threadingly engaging the distal portion 7 of the first coil, and a distal portion 10 terminating into a tip 15.
