| 20160121129 | SYSTEM AND METHOD FOR LOW POWER COMMUNICATION BETWEEN IMPLANTABLE DEVICES - In accordance with an embodiment, apparatuses and methods are provided for coordinating operation between leadless pacemakers (LPs) located in different chambers of the heart. A method includes configuring a local LP to receive communications from a remote LP through conductive communication over first and second channels, maintaining the first channel active for at least a portion of a time when the second channel is inactive to listen for event messages from the remote LP, detecting an incoming signal at the local LP over the first channel, determining whether the incoming signal received over the first channel corresponds to an LP wakeup notice, when the incoming signal corresponds to the LP wakeup notice, activating the second channel at the local LP, and receiving an event message over the second channel from the remote LP. | 05-05-2016 |
| 20160158561 | SYSTEMS AND METHODS FOR FIXATING TRANSVENOUSLY IMPLANTED MEDICAL DEVICES - A transvenously implantable medical device (TIMD) includes an electrical lead and a control module. The electrical lead includes one or more electrodes and is adapted for transvenous implantation. The electrical lead is also pre-biased to expand from a collapsed state to an expanded state to mechanically engage an internal wall of a blood vessel. The control module is secured to and in electrical communication with the electrical lead. The control module includes a signal management component and a power component disposed in a housing adapted for implantation into the blood vessel. The control module is adapted for at least one of stimulating and sensing a physiologic response using the one or more electrodes of the electrical lead. | 06-09-2016 |
