  • Patent number: 10994148
    Abstract: A leadless pacing device may include a power supply for providing a power supply voltage, a housing having a first end and a second end with a side extending between the first end and the second end, and a set of electrodes supported by the housing and in communication with the power supply. When leadless pacing device is disposed within a coronary sinus of a patient's heart, the housing may facilitate blood flow across the housing. The housing may include fixing members extending radially outward from the side of the housing to engage a wall of the coronary sinus and expand the coronary sinus to allow blood to flow past the housing. In some cases, the housing may have a recess along a length thereof that allows blood to flow past the housing. The recess may include a groove, a flat feature, or other feature.

  • Patent number: 10765871
    Abstract: An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing, a pressure sensor and a fluid filled cavity. The housing has a diaphragm that is exposed to the environment outside of the housing. The pressure sensor has a pressure sensor diaphragm that is responsive to a pressure applied to the pressure sensor diaphragm and provides a pressure sensor output signal that is representative of the pressure applied to the pressure sensor diaphragm. The fluid filled cavity is in fluid communication with both the diaphragm of the housing and the pressure sensor diaphragm of the pressure sensor. The fluid filled cavity is configured to communicate a measure related to the pressure applied by the environment to the diaphragm of the housing to the pressure sensor diaphragm of the pressure sensor.
