Abstract
The present invention provides a defect patch device and method that patches a defect in the heart or other cardiovascular tissue. One aspect provides a PFO closure device and method that patches a PFO in the right atrium without the device extending through the PFO into the left atrium. The patch device includes a patch and a heart tissue engaging member for attaching the device over the defect. A deployment device and method includes a device positioner to advance the device out of a catheter and to position the device over the defect to attach the device to the tissue around the defect. The positioner may include a device expander or opener that opens the device for deployment.
