1. An anchor element assembly comprising:
- at least one anchor element having a longitudinal axis, the at least one anchor element comprising;
at least two engagement portions;
at least one lobe section positioned between the at least two engagement portion, the at least one lobe section comprising at least one lobe configured to extend transversely from the longitudinal axis of the at least one anchor element when the at least one anchor element is in a deployed state, the at least one lobe comprising a first end and a second end each being coupled to one respective engagement portion of the at least two engagement portions, the at least one lobe having a middle section positioned between the first end and the second end along the longitudinal axis, the middle section configured to define a laterally outermost portion of the at least one lobe, taken in direction transverse to the longitudinal axis, when the at least one anchor element is in the deployed state, the first end and the second end being separated by the middle portion when the at least one anchor element is in an initial state in a direction along the longitudinal axis; and
a lumen formed within the at least one anchor element configured to receive at least a portion of a medical device in the lumen, the at least one lobe portion being defined by at least one slot in the at least one lobe section extending from an outer surface of the at least one anchor element to the lumen; and
an anchor deployment device comprising;
a first cannula configured to receive the at least one anchor element thereon and to receive a portion of the medical device therein, wherein the first cannula is separate from the medical device to which the at least anchor device is to be secured; and
a second cannula having configured to have at least a portion of the first cannula received therein, wherein the first cannula is movable relative to the second cannula, and wherein the second cannula is configured to;
force one of the at least two engagement portions of the at least one anchor element toward another of the at least two engagement portions in order to position the at least one anchor element in the deployed state while the at least one anchor element is positioned on the first cannula; and
force the at least one anchor element in the deployed state off of the first cannula in order to secure the anchor deployment device to the at least a portion of the medical device that is positioned within a subject, wherein the anchor deployment device is configured to be removed from the subject and the medical device after the at least one anchor device has been secured, and wherein neither the anchor deployment device nor the first cannula is configured to be secured in the subject by the at least one anchor element.

Abstract
Anchor elements include at least one protrusion configured to extend transversely from a longitudinal axis of the anchor element when the anchor element is in a deployed state. Anchor element assemblies and medical device assemblies may include such anchor elements. Methods of anchoring a medical device within a subject include securing at least a portion of the medical device within a lumen of at least one anchor element and deploying at least one protrusion of the at least one anchor element.

19. A method of anchoring a medical device, the method comprising:
-
positioning at least a portion of the medical device in a subject; positioning a lumen of at least one anchor element around a first portion of an anchor deployment device that is separate from and movable relative to the medical device; deploying at least two protrusions of the at least one anchor element to extend transversely from a longitudinal axis of the at least one anchor element while the at least a portion of the medical device is positioned within the subject with a second portion of the anchor deployment device while to the at least one anchor element remains positioned around the first portion of the anchor deployment device, each of the at least two protrusions defined by a middle portion the at least one anchor element that defines the lumen when the at least one anchor element is in an initial state and defines a laterally outermost portion of the at least one anchor element when the at least one anchor element is in a deployed state; and securing the at least a portion of the medical device within the lumen of the at least one anchor element by forcing the at least one anchor element off of the first portion of the anchor deployment device in the deployed state with the second portion of the anchor deployment device. - View Dependent Claims (20)
