Medical device anchoring

A medical system comprising:

• an implantable medical device;
• a therapy delivery device configured to be coupled to the implantable medical device;
• and
• an apparatus configured to anchor a portion of the therapy delivery device within a cranial burr hole formed in a cranium, comprising:
• a first part comprising an outer sidewall extending around a longitudinal axis of the apparatus to define an outer perimeter, at least a portion of which is configured to interface with the cranium, the first part further comprising first and second inner sidewalls extending alongside one another within the outer sidewall, the first and second inner sidewalls being spaced apart to receive the therapy delivery device therebetween;
• and
• a second part comprising a lower surface, first and second activation members protruding from the lower surface, and a slot configured to receive the therapy delivery device, wherein the first activation member is located on one side of the slot and the second activation member is located on another side of the slot;
• and
• wherein the second part is configured to be moved generally along the longitudinal axis toward the first part to thereby cause the first and second activation members to move the first and second inner sidewalls toward one another, the first and second inner sidewalls thereby anchoring the therapy delivery device therebetween when the therapy delivery device is received in the slot of the second part.

An apparatus for anchoring a therapy delivery device within a body portal, comprising:

• a base ring configured to be seated within the body portal and comprising a sidewall;
• a first part comprising an outer sidewall and opposing grip surfaces, the outer sidewall extending around a longitudinal axis of the apparatus to define an outer perimeter, the opposing grip surfaces facing toward the longitudinal axis and being configured to receive the therapy delivery device therebetween, wherein the outer sidewall of the first part is configured to engage the sidewall of the base ring;
• a second part comprising a lower surface, first and second activation members protruding from the lower surface, and a slot configured to receive the therapy delivery device, wherein the first activation member is located on one side of the slot and the second activation member is located on another side of the slot;
• and
• wherein, when the therapy delivery device is received in the slot and the second part is moved generally along the longitudinal axis, the first and second activation members move the opposing grip surfaces toward one another to thereby anchor the therapy delivery device between the opposing grip surfaces.

A medical system comprising:

• an implantable medical device;
• a therapy delivery device configured to be coupled to the implantable medical device;
• and
• an apparatus configured to anchor a portion of the therapy delivery device within a body portal, comprising:
• a base ring comprising a sidewall configured to form a perimeter surface of the body portal when the apparatus is fitted within the body portal;
• a first part comprising an outer sidewall extending around a longitudinal axis of the apparatus to define an outer perimeter, the outer sidewall of the first part configured to contact the sidewall of the base ring, the first part further comprising first and second inner sidewalls extending alongside one another within the outer sidewall, the first and second inner sidewalls being spaced apart to receive the therapy delivery device therebetween;
• and
• a second part comprising a lower surface, first and second activation members protruding from the lower surface, and a slot configured to receive the therapy delivery device, wherein the first activation member is located on one side of the slot and the second activation member is located on another side of the slot;
• and
• wherein the second part is configured to be moved generally along the longitudinal axis toward the first part to thereby cause the first and second activation members to move the first and second inner sidewalls toward one another, the first and second inner sidewalls thereby anchoring the therapy delivery device therebetween when the therapy delivery device is received in the slot of the second part.
