Abstract

A therapeutic delivery device is provided wherein a delivery body is supported by an elongate member such that the body may rotate as it delivers therapeutic to a target site. Therapeutic may be delivered by deploying delivery heads into a target site as well as by dispensing therapeutic from the delivery head. The delivery body may be cylindrically shaped, spherically shaped or shaped in various other configurations. In one embodiment the delivery body contains tracks that may roll back and forth over a target site to dispense therapeutic. In another embodiment, the delivery heads of the delivery body have internal valves that open and close in order to dispense therapeutic.

Claims

1. A therapeutic delivery device comprising:

a steerable elongated member sized for insertion into a body of a patient; and

a rotatable therapeutic delivery body rotatably supported by the elongated member;

the delivery body free to rotate about at least one axis of rotation,

the delivery body having one or more therapeutic delivery ports,

the rotatable therapeutic delivery body sized for insertion into a body of a patient.

2. The therapeutic delivery device of claim 1 wherein the therapeutic delivery port is detachable from the delivery body and wherein the delivery body comprises a therapeutic.

3. The therapeutic delivery device of claim 1 wherein the therapeutic delivery port is in fluid communication with a lumen within the delivery body.

4. The therapeutic delivery device of claim 1 wherein the elongated member further comprises an axle about which the delivery body is rotatably supported.

5. The therapeutic delivery device of claim 1 wherein the delivery port is defined by a delivery head, the delivery head having a plunger slidable within the delivery head.

6. The therapeutic delivery device of claim 1 wherein the delivery port is movable from a first retracted orientation to a second larger expanded orientation.

7. The therapeutic delivery device of claim 1 wherein the delivery body is rotatable about a longitudinal axis of the delivery body.

8. The therapeutic delivery device of claim 1 wherein the delivery body is spherical.

9. The therapeutic delivery device of claim 1 wherein the delivery port is retractable into the delivery body.

10. The therapeutic delivery device of claim 1 wherein the delivery body comprises a track belt and wherein the delivery port is positioned on the track belt.

11. The therapeutic delivery device of claim 1 wherein the elongated member has a distal region and wherein the delivery body is positioned in the distal region of the delivery device.

12. The therapeutic delivery device of claim 6 wherein the delivery body is stellate.

13. The therapeutic delivery device of claim 9 wherein the delivery body is spherical and wherein the delivery port is in an extended position in a first orientation and is in a retracted position in a second orientation.

14. The therapeutic delivery device of claim 1 wherein the delivery body has a longitudinal axis of rotation and wherein an outer surface of the delivery body is defined by a radius extending from the longitudinal axis of rotation.

15. The therapeutic delivery device of claim 2 wherein the delivery port has a piercing surface.

16. The therapeutic delivery device of claim 1 wherein the delivery body is coated with a therapeutic.

17. The therapeutic delivery device of claim 1 wherein the delivery port is coated with a therapeutic.

18. The therapeutic delivery device of claim 1 wherein the delivery body is an expandable balloon.

19. The therapeutic delivery device of claim 1 further comprising a cover surrounding at least a portion of the elongate member, the elongate member slidable within the cover.

20. The therapeutic delivery device of claim 1 wherein the cover is an endoscope.

21. The therapeutic delivery device of claim 1 wherein the delivery body includes an expandable bladder, the bladder sized to force therapeutic from the delivery body through the delivery port as the bladder expands within the delivery body.
