US Patent:

20120290075, Nov 15, 2012
Filed:

May 10, 2011
Appl. No.:

13/104797
Inventors:

DEREK MORTISEN - San Francisco CA, US
YUNBING WANG - Sunnyvale CA, US
Assignee:

Abbott Cardiovascular Systems Inc. - Santa Clara CA
International Classification:

A61F 2/82
US Classification:

623 142
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.

US Patent:

20140336747, Nov 13, 2014
Filed:

Apr 15, 2014
Appl. No.:

14/253760
Inventors:

- Santa Clara CA, US
Nadine Ding - San Jose CA, US
Yunbing Wang - Sunnyvale CA, US
Stephen Pacetti - San Jose CA, US
Derek Mortisen - Palo Alto CA, US
International Classification:

A61F 2/82
A61L 29/16
A61L 29/14
US Classification:

623 115, 623 11, 623 139, 623 138, 623 143
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.
