## Abstract

In at least one embodiment, a system and method for implanting an implantable medical device (IMD) within a patient may include an IMD including a housing and an attachment member, and a delivery catheter including a tethering snare that is configured to be selectively extended out of the delivery catheter and retracted into the delivery catheter. In at least one embodiment, a system and method for implanting an implantable medical device (IMD) within a patient may include an IMD including a housing and an attachment member, wherein the attachment member includes a central passage connected to a connection chamber, and a delivery catheter including first and second tethers that may be moved outwardly from and retracted into the delivery catheter.

## Claims

### Claim 1

A system for implanting an implantable medical device (IMD) within a patient, the system comprising:
a delivery catheter including first and second tethers that may be moved outwardly from and retracted into the delivery catheter, wherein the first tether includes a protuberance at a first distal end, and wherein the second tether includes an elongated interfering segment at a second distal end; and
an IMD including a housing and an attachment member, wherein the attachment member includes a neck extending from the housing, and an expanded head connected to the neck and having a central passage connected to a connection chamber within the expanded head, wherein the connection chamber is wider than the central passage and longer than the protuberance such that the protuberance is lodged within the connection chamber to securely tether the IMD to the delivery catheter when the elongated interfering segment is moved outwardly from the delivery catheter and positioned in the central passage, and wherein the protuberance is configured to dislodge from the connection chamber when the elongated interfering segment is retracted into the delivery catheter and removed from the central passage.

### Claim 2 (depends on 1)

The system of claim 1, wherein the elongated interfering segment is devoid of any protuberance, and wherein a combined diameter of the protuberance and the elongated interfering segment is greater than a passage diameter of the central passage.

### Claim 3 (depends on 1)

The system of claim 1, wherein a protuberance diameter of the protuberance is less than a passage diameter of the central passage.

### Claim 4 (depends on 3)

The system of claim 3, wherein a tether diameter of the elongated interfering segment of the second tether is less than either of the passage diameter and the protuberance diameter.

### Claim 5 (depends on 4)

The system of claim 4, wherein a combined diameter of the tether diameter and the protuberance diameter is greater than the passage diameter.

### Claim 6

A method for implanting an implantable medical device (IMD) within a patient, the method comprising:
securing the IMD to a delivery catheter by positioning a first tether of the delivery catheter within a central passage of an attachment member of the IMD, wherein the attachment member includes a neck extending from a housing of the IMD, an expanded head connected to the neck, and a central passage connected to a connection chamber within the expanded head, and wherein the connection chamber is wider than the central passage and longer than a protuberance such that positioning the first tether within the central passage lodges the protuberance within the connection chamber; and
releasing the IMD from the delivery catheter by removing the first tether from the central passage, wherein removing the first tether from the central passage allows the protuberance to dislodge from the connection chamber and to be removed from the central passage.

### Claim 7 (depends on 6)

The method of claim 6, wherein a protuberance diameter of the protuberance is less than a passage diameter of the central passage.

### Claim 8 (depends on 7)

The method of claim 7, wherein a tether diameter of the first tether is less than either of the passage diameter and the protuberance diameter, and wherein a combined diameter of the tether diameter and the protuberance diameter is greater than the passage diameter.

### Claim 9 (depends on 1)

The system of claim 1, wherein the neck is pivotally secured to the housing.

### Claim 10 (depends on 1)

The system of claim 1, wherein the attachment member includes at least one torque recess.

### Claim 11 (depends on 6)

The system of claim 6, wherein the neck is pivotally secured to the housing.

### Claim 12 (depends on 6)

The system of claim 6, wherein the attachment member includes at least one torque recess.

### Claim 13 (depends on 6)

The system of claim 6, wherein the first tether is devoid of any protuberance, and wherein a combined diameter of the protuberance and the first tether is greater than a passage diameter of the central passage.
