Abstract

A device implantable in tissue of a prostate gland or a bladder is described. The device includes a device body, a retrieval portion, a medicament, and a medicament carrier. The device body includes a first end and a second end opposite of the first end. The first end has a sharp tip adapted for penetrating the tissue. The retrieval portion connected to the second end of the device body. The medicament is applied to the device to therapeutically treat the prostate gland or the bladder. The carrier is a hydrogel, a silicone based material, an elastomer, a proteinaceous material, a polyethylene glycol material, a carbohydrate material, or a polysaccharide carbohydrate material that provides controlled delivery of the medicament over a duration of time.

First claim

What is claimed is:

1. A device implantable in tissue of one of a prostate gland and a bladder, the device comprising: a device body including a first end and a second end opposite of the first end, the first end having a sharp tip adapted for penetrating the tissue and the second end of the device body provides a head of the device;
a retrieval portion connected to the second end of the device body;
a medicament applied to the head of the device to therapeutically treat the one of the prostate gland and the bladder; and
a carrier applied to the device; wherein the carrier is one of a hydrogel, a silicone based material, an elastomer, a proteinaceous material, a polyethylene glycol material, a carbohydrate material, and a polysaccharide carbohydrate material that provides controlled delivery of the medicament over a duration of time.

2. The device of claim 1 , wherein the device body is absorbable.

3. The device of claim 1 , wherein the device body is formed to provide a spiral shape.

4. The device of claim 1 , wherein the device body is formed to provide a J-shape.

5. The device of claim 1 , wherein the device body is formed to provide a U-shape.

6. The device of claim 1 , wherein the device body is a mesh.

7. The device of claim 1 , wherein the device body is cylindrical mesh.

8. The device of claim 1 , wherein the head of the device has a diameter that is larger than a diameter of the first end of the device.

9. The device of claim 1 , wherein the retrieval portion is a one of a length of a cord, a twine, a fiber, and a string.
