  • Patent number: 9642730
    Abstract: Methods for making scaffolds for delivery via a balloon catheter are described. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold structure has patterns that include an asymmetric or symmetric closed cell, and links connecting such closed cells.
    Type: Grant
    Filed: April 1, 2016

  • Publication number: 20160250049
    Abstract: A drug eluting stent can include a stent body having a polymeric coating with a lipophilic and/or hydrophilic element. A drug that has a bioactivity that inhibits cell proliferation can be disposed in the polymeric coating. The drug can be present in the polymer at an amount greater than or equal to about 150 ?g/cm2. The polymeric coating and drug are configured to cooperate so as to form a diffusion pathway with tissue when the stent is disposed in a body lumen such that the drug preferentially diffuses into the tissue over a body fluid passing through the body lumen such that a maximum systemic blood concentration of the drug is less than about 40 ng/ml.

  • Patent number: 5865768
    Abstract: The present invention is for a guide wire comprising a core wire with a first diameter and the distal end having at least one section having a second, lesser diameter and a radiolucent coil surrounding the distal end at the second core wire diameter with a radiopaque wire located at the distal end within the radiolucent coil and a means for securing the radiopaque wire to the core wire.

  • Patent number: 5853375
    Abstract: A guide wire extension assembly for angioplasty comprising a guide wire and an extension wire that utilize a peg and hole connection. The proximal end of the guide wire and the distal end of the extension wire have connector members attached that allow for mating the ends of the guide wire and extension wire together. In one embodiment the first connector member has a horizontal surface with a hole that is perpendicular to the horizontal surface. The second connector member has a horizontal surface with a peg extending upwardly from the horizontal surface, such that when the first connector member and the second connector member are joined, the peg and the hole fit together. In another embodiment, the first connection member and the second connection member are made from magnetic material so that when the peg is inserted in the hole, it is held in place by magnetic attraction.
