Anchor and anchor deployment apparatus
First Claim
1. An anchor deployment apparatus for deploying an anchor about a therapy delivery element, wherein the anchor has 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, the anchor deployment apparatus 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 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 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 proximally relative to the engagement element.
