Patent number: 9545301Abstract: Coating methods and related devices are provided. Such devices can include stents. For example, the device can comprise 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 also comprise an anti-thrombogenic coating distributed over at least a portion of the device such that the pores are substantially free of webs formed by the coating.Type: GrantFiled: June 27, 2014Date of Patent: January 17, 2017Assignee: Covidien LPInventors: John Wainwright, Todd Mendelson, Kurt Haggstrom, Masoud Molaei, Victoria Schuman, Min-Shyan Sheu

Publication number: 20150065965Abstract: A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.Type: ApplicationFiled: September 8, 2014Publication date: March 5, 2015Inventors: Kurt Haggstrom, Alain Tranchemontagne, Loredana Jinga
