  • Modification of bioabsorbable stent to reduce thrombogenecity
    Patent number: 9750852
    Abstract: Bioabsorbable polymer scaffolds with coatings are disclosed that include immobilized antithrombotic agents on the scaffolds or in or on the coatings. The agents act synergistically with antiproliferative agents released from coatings by providing hemocompatibility during and without interfering with antiproliferative agent release. Methods of modifying scaffolds and coatings with the antithrombotic agents are disclosed.
    Type: Grant
    Filed: June 21, 2016
    Date of Patent: September 5, 2017
    Assignee: Abbott Cardiovascular Systems Inc.
    Inventors: Derek Mortisen, Yunbing Wang

  • BIORESORBABLE IMPLANTS FOR TRANSMYOCARDIAL REVASCULARIZATION
    Publication number: 20140336747
    Abstract: Implants for treating insufficient blood flow to a heart muscle with transmyocardial revascularization are disclosed. Methods of treating insufficient blood flow to a heart muscle with the implant are also disclosed. The implant can have a body with an inner lumen that supports a channel in the heart muscle to allow for increased blood flow through the lumen upon implantation. The implant can include active agents to prevent or inhibit thrombotic closure of the channel, to promote vascularization, or both.
