US Patent:

8147415, Apr 3, 2012
Filed:

Mar 30, 2009
Appl. No.:

12/414465
Inventors:

Wangcai Liao - Cary NC, US
Jeffrey Stahmann - Ramsey MN, US
Bin Mi - Plymouth MN, US
Yunlong Zhang - Mounds View MN, US
Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:

A61B 5/02
US Classification:

600485, 600301, 600486
Abstract:

Systems and methods provide for ambulatorily sensing pulmonary artery pressure from within a patient, and producing a pulmonary artery pressure measurement from the sensed pulmonary artery pressure. Power is ambulatorily provided within the patient to facilitate sensing of the pulmonary artery pressure and producing of the pulmonary artery pressure measurement. Acute pulmonary embolism is detected based on a change or rate of change in the pulmonary artery pressure measurement. An alert is preferably generated in response to detecting pulmonary embolism.
