Patent number: 9668890Abstract: 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.Type: GrantFiled: November 22, 2013Date of Patent: June 6, 2017Assignee: Covidien LPInventors: Xiaodong Ma, Min-Shyan Sheu, Lincoln Eramo, John Wainwright, Junwei Li

Patent number: 7909864Abstract: 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.Type: GrantFiled: July 2, 2008Date of Patent: March 22, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Min-Shyan Sheu, Steve Walak, Yixin Xu

Publication number: 20080234659Abstract: 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.Type: ApplicationFiled: March 20, 2008Publication date: September 25, 2008Applicant: Boston Scientific Scimed, Inc.Inventors: Eric Cheng, Jianmin Li, Weena Bucay-Couto, Scott Sanders, James F.
