Publication number: 20160089834Abstract: Methods and systems for manufacturing composite parts that include anodizable portions and non-anodizable portions such that an interface between the anodizable portions and non-anodizable portions are free of visible defects are described. The non-anodizable portions can be made of anodizable metals such as aluminum or aluminum alloy. The non-anodizable portions are made of material that do not generally form an anodic film, such as plastic, ceramic or glass materials. In particular, the methods described relate to manufacturing methods that are compatible with anodizing processes and avoid defects related to anodizing processes. In particular embodiments, the methods involve avoiding trapping of anodizing chemicals within a gap between an anodizable portion and a non-anodizable portion, which prevents the anodizing chemicals from disrupting the uptake of dye in a post-anodizing dyeing process.Type: ApplicationFiled: September 30, 2014Publication date: March 31, 2016Inventors: Stefan C. Mag, Derek C. Krass, Nicholas G. Merz, Daniel W. Jarvis, Matthew P. Rao, Vincent Yan, Michael Ngo, Richard Hung Minh Dinh, Thomas Johannessen

Publication number: 20150305943Abstract: A polymeric stent can be implanted for treatment of the Eustachian tube. The stent can be designed to have length-dependent radial strength to allow it to stay within the Eustachian tube and to allow normal closing and opening of the Eustachian tube. A balloon can be used to implant the stent, and the balloon can be coated with a therapeutic agent. A coated balloon can also be used to transfer therapeutic agents to the sinus cavity during a balloon sinus dilation procedure.Type: ApplicationFiled: April 29, 2014Publication date: October 29, 2015Inventors: Syed Hossainy, Paul Consigny, Dariush Davalian, James Su, Michael Ngo, Adrain Gale, Jesus Magana, Mikael Trollsas, Evan Norton, Benjamyn Serna

Publication number: 20150196690Abstract: A drug delivery balloon is provided, the a balloon having an outer surface, and a tunable coating disposed on at least a length of the balloon surface. The tunable coating includes a first therapeutic agent and a first excipient, wherein the cytostatic therapeutic agent and the at least one excipient have a weight ratio of about 20:1 to about 1:20, and further wherein the coating provides increased efficiency of therapeutic transfer to a body lumen.Type: ApplicationFiled: January 16, 2015Publication date: July 16, 2015Applicant: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: John Stankus, Mikael Trollsas, Syed Hossainy, Stephen Pacetti, Michael Ngo

Patent number: 8951595Abstract: A drug delivery balloon is provided, the a balloon having an outer surface, and a tunable coating disposed on at least a length of the balloon surface. The tunable coating includes a first therapeutic agent and a first excipient, and can include a second therapeutic agent and a second excipient. The first and second therapeutic agents have different dissolution rates during balloon inflation and therefore provide a coating that is tunable.Type: GrantFiled: December 11, 2009Date of Patent: February 10, 2015Assignee: Abbott Cardiovascular Systems Inc.Inventors: John Stankus, Mikael Trollsas, Syed Hossainy, Stephen Pacetti, Michael Ngo
