## Abstract

An anchor deployment apparatus for deploying an anchor about a therapy delivery element includes an anchor receiving element having an elongate member having a lumen. The lumen is configured to slidably receive at least a portion of a therapy delivery element. The anchor deployment tool further includes an anchor engagement element having (i) a body forming a 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. The engagement feature is configured to engage the anchor when the anchor is disposed about the elongate member and the elongate member is moved 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 relative to the engagement element.

## Claims

### Claim 1

An anchor deployment assembly 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;
an anchor engagement element having (i) a body forming a 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 member, and to cause the anchor to move distally along the elongate member when the engagement feature is engaged with the anchor and the elongate member is moved proximally relative to the anchor engagement element; and
an alignment element securable relative to the elongate member and configured to secure the elongate member relative to the body of the anchor engagement element to restrict movement of the elongate member orthogonal to the axis of the channel.

### Claim 2 (depends on 1)

The assembly of claim 1, wherein the anchor receiving element and the alignment element form a single part.

### Claim 3 (depends on 1)

The anchor deployment apparatus of claim 1, wherein the elongate member of the anchor receiving element further comprises a proximal opening and the lumen extends through the elongate member from the proximal opening to the distal opening.

### Claim 4 (depends on 1)

The anchor deployment apparatus of claim 1, wherein the alignment element comprises first and second opposing deflectable arms, wherein in a relaxed configuration at least a portion of the deflectable arms are separated by a distance less than a width of at least a portion of the body of the anchor engagement element.

### Claim 5 (depends on 4)

The anchor deployment apparatus of claim 4, wherein the first and second deflectable arms comprise inwardly extending portions separated by the distance less than a width of at least a portion of the body of the anchor engagement element, wherein the first and second arms are outwardly deflectable such that the inwardly extending portions may be advanced about the body of the anchor engagement element beyond the portion having a width greater than the distance between the inwardly extending portions in a relaxed state.

### Claim 6 (depends on 5)

The anchor deployment apparatus of claim 5, wherein the body of the anchor engagement element comprises first and second generally opposing indented portions having a width less than the distance between the inwardly deflectable portions in a relaxed state and are configured to receive the inwardly extending portions of the first and second deflectable arms.

### Claim 7 (depends on 6)

The anchor deployment apparatus of claim 6, wherein the indented portions extend a distance along the length of the body of the anchor receiving element and are configured to slidably receive the inwardly extending portions of the first and second deflectable arms.

### Claim 8 (depends on 1)

The anchor deployment apparatus of claim 1, wherein the alignment element further comprises a rail slidably receivable by the channel of the anchor engagement element.

### Claim 9 (depends on 8)

The anchor deployment apparatus of claim 8, wherein the rail is coaxial with the elongate member of the anchor receiving element.

### Claim 10 (depends on 1)

The anchor deployment apparatus of claim 1, wherein the alignment element forms a part of a handle of the anchor receiving element.

### Claim 11 (depends on 1)

The anchor deployment apparatus of claim 1, wherein the anchor engagement element further comprises a stop feature that protrudes into the channel, wherein the stop feature is configured and positioned to engage the alignment element and to prevent the alignment element from being moved proximally in the channel once engaged by the stop feature.

### Claim 12 (depends on 1)

The anchor deployment apparatus of claim 1, wherein the channel comprises a distal ramp to facilitate exit and extension of a proximal portion of a therapy delivery element beyond a distal portion of the channel when the therapy delivery element is slid proximally in the channel.

### Claim 13 (depends on 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 at least a portion of the lumen of the anchor and smaller than the second inner diameter of at least a portion of the lumen of the anchor; and
an anchor deployment apparatus according to claim 1.

### Claim 14 (depends on 1)

A kit comprising:
an anchor having (i) a first opening, (ii) a second opening, (iii) a body member disposed between the first and second opening, (iv) 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,
wherein the body member is formed from elastic material, the lumen is configured to be disposed about at least a portion of the outer surface of a therapy delivery element, and 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, the first inner diameter being smaller than the second inner diameter; and
and an anchor deployment apparatus according to claim 1,
wherein the elongate member of the anchor receiving element of the anchor deployment apparatus has an outer diameter larger than the first inner diameter of at least a portion of the lumen of the anchor and smaller than the second inner diameter of 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, 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.

### Claim 15 (depends on 14)

The kit according of claim 14, wherein the anchor is preloaded about the elongate member of the anchor receiving element.

### Claim 16 (depends on 15)

The kit of claim 15, wherein the kit comprises more than one anchor receiving elements, wherein an anchor is preloaded about each of the elongate members of the anchor receiving elements.

### Claim 17 (depends on 16)

The kit of claim 16, wherein each preloaded anchor is different.

### Claim 18 (depends on 14)

The kit of claim 14, wherein the body member of the anchor is formed from silicone.

### Claim 19 (depends on 14)

The kit of claim 14, wherein the therapy delivery element is selected from the group consisting of a lead and a catheter.
