摘要：
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.
