IMPLANTABLE ELECTRODE LINE
First Claim
1. A fastening device for fixing implantable medical devices to tissue including:
- a. a main body (1) having;
(1) a first end (1a),(2) a second end (1b) bearing an inflexible and inextensible first body support (3),(3) an extensible body section (2) between the first end (1a) and the second end (1b),b. a flexible elongated first anchor (4);
(1) extending from the main body (1), and(2) being attached to the first body support (3) at a first anchor mount (4a), andc. a flexible first retraction device (5) connected between a first anchor fastening location (5b) on the first anchor (4) and a first body fastening location (5a) on the extensible body section (2) of the main body (1), the first retraction device (5) serving as a tether on the first anchor (4), whereby tension on the first retraction device (5) is transmitted to the first anchor (4);
the extensible body section (2) being convertible from an unextended state into an extended state wherein;
i. the spacing between the first body fastening location (5a) and the first anchor mount (4a) is increased, andii. the first anchor (4) is pulled by the first retraction device (5) toward the extensible body section (2).

Abstract
A device for fastening permanently or temporarily implantable medical devices includes a main body (1) having a first end (1a) and a second end (1b), a flexible and extensible body section (2) therebetween, and a first inflexible and inextensible body support (3) which is fixedly attached to the body section (2) at the second end (1b) of the main body (1), whereby the extensible section (2) can be converted from an unextended state to an extended state in which it is lengthened in comparison with the unextended state. At least one first flexible finger-shaped anchor (4) protrudes away from the main body (1) and is attached to the first body support (3) at an anchor mount (4a). At least one first flexible retraction device (5) is provided for retraction of a respective first anchoring means (4), wherein the retraction device (5) is connected to the body section (2) and to the anchor (4). On conversion of the body section (2) from the unextended state to the extended state, the retraction device (5) does not expand, so that the respective anchors (4) are moved in the direction of the main body (1).

18. A fastening device for fixing implantable medical devices to tissue including:
-
a. a main body (1) having a body section (2) extending between a first end (1a) and a second end (1b), the body section (2) being extensible along an extension direction to increase the spacing between the first end (1a) and the second end (1b); b. an elongated first anchor (4) extending from a first anchor mount (4a) on the main body (1), at least a portion of the length of the first anchor (4) being flexible, whereby the first anchor (4) may flex between; (1) an unextended state wherein the first anchor (4) is oriented more perpendicular to the extension direction, (2) an extended state wherein the first anchor (4) is oriented more parallel to the extension direction, c. a first tether (5) extending between; (1) one or more first anchor fastening locations (5b) on the first anchor (4) spaced from the first anchor mount (4a), and (2) one or more first body fastening locations (5a) on the extensible body section (2) spaced from the first anchor mount (4a), wherein extension of the body section (2) flexes the first anchor (4) toward the extended state as the distance between the first body fastening locations (5a) and the first anchor mount (4a) increases. - View Dependent Claims (19, 20, 21, 22, 23, 25)

24. A fastening device for fixing implantable medical devices to tissue including:
-
a. a main body (1) having a body section (2) extending between a first anchor mount (4a) and a second anchor mount (7a), the body section (2) being extensible along an extension direction to increase the spacing between the first anchor mount (4a) and the second anchor mount (7a); b. an elongated first anchor (4) extending from the first anchor mount (4a) on the main body (1), at least a portion of the length of the first anchor (4) being flexible; c. an elongated second anchor (7) extending from the second anchor mount (7a) on the main body (1), at least a portion of the length of the second anchor (7) being flexible, wherein extension of the body section (2) flexes the first anchor (4) and the second anchor (7) toward each other.
