  • Patent number: 10137012
    Abstract: Methods for forming an expandable tubular body having a plurality of braided filaments including a first filament including platinum or platinum alloy and a second filament including cobalt-chromium alloy. The methods include applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament and applying a silane material on the second filament followed by a second phosphorylcholine material on the silane material on the second filament. The first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.

  • Patent number: 9668890
    Abstract: Methods for applying layers to medical devices and related devices are provided. Such devices can include stents. For example, the device can include a sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm. The device can have an anti-thrombogenic outer layer distributed over at least a portion of the device.

  • Publication number: 20170119557
    Abstract: Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm, the pores have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.

  • Publication number: 20110171272
    Abstract: According to an aspect of the invention, urological medical devices are provided, which comprise a prostatically beneficial agent selected from alpha-adrenergic blockers, antispasmodic agents, anticholinergic/antimuscarinic agents, calcium channel blockers, anti-inflammatory agents, hormone affecting agents, anti-cancer agents, and combinations thereof, among others. The urological medical devices are adapted for implantation or insertion into a subject's urinary tract, whereupon at least a portion of the prostatically beneficial agent is released into the subject's prostatic urethra. The release profile of the prostatically beneficial agent is effective to treat a prostatic disorder, for example, benign prostate hypertrophy, prostate cancer or prostatitis, among others. Other aspects of the invention are directed to treating prostatic disorders.

  • Patent number: 7909864
    Abstract: The present invention is directed to implantable medical devices which may be used for controllably releasing a therapeutic agent within a patient and methods for making the same. These medical devices may include porous coatings, which may be polymer-free, located on an outer surface or abluminal surface of the medical device. The medical device may be a stent. The pores of the porous coating may be expandable to facilitate loading of the therapeutic agent. The medical device may be triggerable upon implantation of the medical device such that the volume of the voids shrinks to eject the therapeutic agent. The voids may be slots in the stent. Expandable materials or structures may be positioned in the voids to expand upon implantation and eject the therapeutic agent.

  • Publication number: 20080234659
    Abstract: According to an aspect of the present invention, urological medical devices are provided, which contain one or more urologically beneficial agents selected from alpha-adrenergic blockers, calcium channel blockers, and combinations thereof, among others. The urological devices are adapted for implantation or insertion into a subject's urinary tract, whereupon at least a portion of the urologically beneficial agent is released. Such agents are urologically beneficial, for example, in that they may relieve pain and/or discomfort associated with the medical device and/or act as stone expulsion agents (i.e., they facilitate stone passage), among other benefits. According to an aspect of the present invention, a method of treating kidney stones is provided which comprises: (a) diagnosing the presence of kidney stones within a subject and (b) implanting or inserting a urological medical device into the subject which contains at least one urologically beneficial agent.
