Implantable medical device

A medical device configured to be positioned within an anatomical volume defined by a body of a patient, the medical device comprising:

• a housing configured to be positioned within an anatomical volume defined by a body of a patient, the housing defining a housing distal portion and a defining a device axis extending through the housing distal portion, wherein the housing distal portion defines a housing distal end;
• a first helical body configured to engage tissues, the first helical body extending in a distal direction from a first base portion coupled to the housing distal portion to a first distal end distal to the housing distal end, the first helical body surrounding the device axis, and the first helical body defining a helical handedness, the handedness being one of a right-handedness or a left handedness;
• a second helical body configured to engage the tissues as the first helical body engages the tissues, the second helical body extending in the distal direction from a second base portion coupled to the housing distal portion to a second distal end distal to the housing distal end, the second helical body surrounding the device axis, and the second helical body defining the helical handedness,
• wherein the first helical body defines a first helical axis angularly displaced from the device axis by a first angle, and
• wherein the second helical body defines a second helical axis angularly displaced from the device axis by a second angle.

A method, comprising:

• engaging, using a first helical body, tissues of a body of a patient, the first helical body extending in a distal direction from a housing defining a housing distal portion and a defining a device axis extending through the housing distal portion, wherein the housing distal portion defines a housing distal end, and the first helical body extending from a first base portion coupled to the housing distal portion to a first distal end distal to the housing distal end, wherein the first helical body surrounds the device axis and the first helical body defines a helical handedness, the handedness being one of a right-handedness or a left handedness;
• engaging, using a second helical body, the tissues of the body of the patient, the second helical body extending in the distal direction from the housing, the second helical body extending from a second base portion coupled to the housing distal portion to a second distal end distal to the housing distal end, wherein the second helical body surrounds the device axis and the second helical body defines the helical handedness;
• and
• communicating, using processing circuitry configured to at least one of provide therapy to the patient or sense a signal from the patient, with an electrode supported by one of the first helical body, the second helical body, or the housing.
