ANCHOR AND ANCHOR DEPLOYMENT APPARATUS
First Claim
1. A system comprising:
- an anchor having a first opening, a second opening, a body member disposed between the first and second opening, and a lumen extending though the body member from the first opening to the second opening, wherein the body member is formed from an elastic material and wherein at least a portion of the body member has a first inner diameter defined by the lumen in a relaxed state and a second inner diameter defined by the lumen in a radially stretched state, wherein the first inner diameter is smaller than the second inner diameter;
a therapy delivery element having an outer diameter and an outer surface about which the anchor is disposable, the outer diameter being larger than the first inner diameter of the at least a portion of the lumen of the anchor and smaller than the second inner diameter of the at least a portion of the lumen of the anchor; and
an anchor deployment apparatus including an anchor receiving element,the anchor receiving element comprising an elongate member having a distal opening and a lumen extending proximally in the elongate member from the distal opening,wherein the lumen of the elongate member is configured to slidably receive at least a portion of the therapy delivery element,wherein the elongate member has an outer diameter larger than the first inner diameter of the at least a portion of the lumen of the anchor and smaller than the second inner diameter of the at least a portion of the lumen of the anchor such that the anchor is disposable about the elongate member and, when the anchor is disposed about the elongate member, the at least a portion of the lumen of the anchor engages at least a portion of the elongate member, and wherein the anchor is moveable about the elongate member.

Abstract
An anchor for maintaining a portion of a therapy delivery element within a desired location of a patient has (i) a first opening, (ii) a second opening, (iii) a body member formed of elastic material disposed between the first and second opening, (iv) and a lumen extending though the body member from the first opening to the second opening, and (v) a retention element secured to or integrally formed with the body member for retaining the anchor within a tissue location of a patient. The therapy delivery element has an outer diameter and an outer surface about which the anchor is disposable. The body member has a first inner diameter defined by the lumen in a relaxed state and a second inner diameter defined by the lumen in a radially stretched state. The first inner diameter is smaller than the outer diameter of the therapy delivery element, which is smaller that the second inner diameter. The lumen is configured to be disposed about at least a portion of the therapy delivery element. Radially compressive forces, due to the elastic material of the body member, contribute to retaining the anchor relative to the therapy delivery element.

4. An anchor deployment apparatus for deploying an anchor about a therapy delivery element, comprising:
-
an anchor receiving element having an elongate member having a distal opening and a lumen extending proximally in the elongate member from the distal opening, the lumen of the elongate member being configured to slidably receive at least a portion of a therapy delivery element; and an anchor engagement element having (i) a first channel in which the elongate member of the anchor receiving element is axially movable, and (ii) an engagement feature forming at least a part of the channel, wherein the engagement feature is configured to engage the anchor when the anchor is disposed about the elongate member and the elongate member is moved distally relative to the engagement element, and to cause the anchor to move distally along the elongate member when the feature is engaged with the anchor and the elongate member is moved distally relative to the engagement element. - View Dependent Claims (5, 6, 7, 8, 9, 15, 16, 17, 18, 19, 20)

10. An anchor for maintaining a portion of a therapy delivery element within a desired location of a patient, the therapy delivery element having an outer diameter and an outer surface about which the anchor is disposable, the anchor comprising:
-
a first opening; a second opening; a body member disposed between the first and second opening, the body member being formed from elastic material; and a lumen extending though the body member from the first opening to the second opening, the lumen being configured to be disposed about at least a portion of the outer surface of the therapy delivery element; and a retention element secured to or integrally formed with the body member for retaining the anchor within a tissue location of a patient, wherein at least a portion of the body member has a first inner diameter defined by the lumen in a relaxed state and a second inner diameter defined by the lumen in a radially stretched state, wherein the first inner diameter is smaller than the second inner diameter, and wherein the first inner diameter is configured to be smaller than the outer diameter of the therapy delivery element, and the second inner diameter is configured to be larger than the outer diameter of the therapy delivery element. - View Dependent Claims (11, 12, 13, 14)
