## Abstract

A surgical implant includes a biocompatible member configured for securement to an underlying target surgical site and a radiation source integrated into or onto the biocompatible member. The surgical implant may be one of a clip, pin, or coil and the radiation source includes at least one brachytherapy capsule, or other radioactive material incorporated therein or provided thereon. The radioactive material provides a dose of radiation to the target surgical site. The surgical implant may also be formed from titanium, stainless steel or polymers. A surgical applier is provided for allowing a surgeon to apply the implant to a patient's tissue.

## Claims

### Claim 1

A surgical implant comprising:
a backspan including a first end and a second end, the backspan including an inner surface configured to face tissue and an opposing outer surface, wherein the backspan is substantially v-shaped and includes first and second segments extending from the respective first and second ends of the backspan to an apex;
a first leg extending from the first end of the backspan;
a second leg extending from the second end of the backspan in the same direction as the first leg;
at least one first brachytherapy capsule of a plurality of first brachytherapy capsules integrated into and embedded partially and transversely within the inner surface of the backspan at the apex, wherein the plurality of first brachytherapy capsules are interspaced from each other and integrated into the backspan; and
a second brachytherapy capsule integrated into the first leg or the second leg in interspaced relation relative to the at least one first brachytherapy capsule.

### Claim 2 (depends on 1)

The surgical implant according to claim 1, wherein the second brachytherapy capsule is one of a plurality of second brachytherapy capsules integrated into the first leg or the second leg, the plurality of second brachytherapy capsules disposed in interspaced relation relative to each other.

### Claim 3 (depends on 2)

The surgical implant according to claim 2, wherein the plurality of second brachytherapy capsules are integrated into both the first and second legs.

### Claim 4 (depends on 2)

The surgical implant according to claim 2, wherein the plurality of second brachytherapy capsules are integrated into the inner surface of the first leg or the inner surface of second leg.

### Claim 5 (depends on 1)

The surgical implant according to claim 1, further comprising a brachytherapy capsule secured to the outer surface of the backspan.

### Claim 6 (depends on 1)

The surgical implant according to claim 1, wherein each of the first and second legs includes an inner surface configured to face the tissue and an opposing outer surface, and the second brachytherapy capsule is integrated into and embedded partially and transversely within the inner surface of the first leg or the second leg.

### Claim 7 (depends on 6)

The surgical implant according to claim 6, further comprising a brachytherapy capsule secured to an outer surface of the first leg or the second leg.

### Claim 8 (depends on 1)

The surgical implant according to claim 1, further comprising a coating of a colored oxide or gold.

### Claim 9

The A surgical applier comprising:
a handle assembly; and
an endoscopic shaft assembly extending from the handle assembly, the endoscopic shaft assembly including a distal portion having a surgical implant loaded therein, the surgical implant including:
a backspan including a first end and a second end, the backspan including an inner surface configured to face tissue and an opposing outer surface;
wherein the backspan is substantially v-shaped and includes first and second segments extending from the respective first and second ends of the backspan to an apex;
a first leg extending from the first end of the backspan;
a second leg extending from the second end of the backspan in the same direction as the first leg;
at least one first brachytherapy capsule of a plurality of first brachytherapy capsules integrated into and embedded partially and transversely within the inner surface of the backspan at the apex;
wherein the plurality of first brachytherapy capsules are interspaced from each other and integrated into the backspan; and
a second brachytherapy capsule integrated into the first leg or the second leg in interspaced relation relative to the at least one first brachytherapy capsule.

### Claim 10

The A method of performing a surgical procedure comprising:
placing a distal portion of an endoscopic shaft assembly of a surgical applier adjacent to tissue at a surgical site, the distal portion of the endoscopic shaft assembly having a surgical implant loaded therein, the surgical implant including:
a backspan including a first end and a second end, the backspan including an inner surface configured to face the tissue and an opposing outer surface, wherein the backspan is substantially v-shaped and includes first and second segments extending from the respective first and second ends of the backspan to an apex;
a first leg extending from the first end of the backspan;
a second leg extending from the second end of the backspan in the same direction as the first leg;
at least one first brachytherapy capsule of a plurality of first brachytherapy capsules integrated into and embedded partially and transversely within the inner surface of the backspan at the apex, wherein the plurality of first brachytherapy capsules are interspaced from each other and integrated into the backspan; and
a second brachytherapy capsule integrated into the first leg or the second leg in interspaced relation relative to the at least one first brachytherapy capsule; and
firing the surgical applier to secure the surgical implant to the tissue.
