Methods and devices for repairing damaged or diseased tissue using a scanning beam assembly
First Claim
1. A method for repairing or modifying an area of a patient'"'"'s anatomy comprising the steps of:
- (a) directing at least a portion of a scanning beam assembly to an area of a patient'"'"'s anatomy, the scanning beam assembly comprising;
a radiation source capable of emitting radiation;
an optical fiber for directing the radiation from the radiation source toward a distal end of the scanning beam assembly in the form of a beam;
a reflector that receives the beam of radiation from the optical fiber to direct the radiation onto the anatomy, wherein the reflector oscillates in at least two directions to create a scan of the anatomy with the radiation, the scan including sinusoidal angular deflections of the reflector yielding a bi-resonant or bi-sinusoidal scan path;
a detector to detect radiation returned from the anatomy; and
a controller to convert the detected radiation into a displayable image of the anatomy that was scanned by the radiation directed thereto by the reflector;
wherein the controller comprises an interface management component that is electrically coupled to a user interface, the reflector, and the radiation source, wherein the interface management component upon receipt of specified treatment parameters transmits signals to a source control to drive the radiation source to provide a requisite emitting radiation output during the bi-resonant or bi-sinusoidal scan path;
(b) applying a radiation-responsive agent to a portion of the anatomy;
(c) exposing the radiation-responsive agent to radiation directed onto the agent by the reflector to cause the agent to therapeutically interact with the site;
(d) imaging the anatomy using the scanning beam assembly;
(e) displaying an image of the anatomy including the agent;
(f) using the displayed image of the anatomy to plan the placement of the radiation-responsive agent; and
(g) selecting a treatment path where the reflector will direct therapeutic radiation for exposing the radiation-responsive agent.

Abstract
A method for repairing or modifying an area of a patient'"'"'s anatomy that comprises directing at least a portion of a scanning beam assembly to an area of a patient'"'"'s anatomy, applying a radiation-responsive agent to portion of the anatomy, and exposing the radiation-responsive agent to radiation directed onto the agent by the reflector to cause the agent to therapeutically interact with the site. The scanning beam assembly including a radiation source capable of emitting radiation, a reflector that receives the radiation from the radiation source to direct the radiation onto the anatomy, wherein the reflector oscillates in at least two directions to create a scan of the anatomy, a detector to detect radiation returned from the anatomy, and a controller to convert the detected radiation into a displayable anatomy image.

40. A balloon catheter comprising:
-
(a) an expandable balloon; (b) a catheter body having a plurality of lumens, wherein at least one lumen opens into the interior of the expandable balloon; and (c) at least a portion of a scanning beam assembly, the scanning beam assembly comprising; a radiation source capable of emitting radiation; a reflector that receives the radiation from the radiation source to direct the radiation onto a patient'"'"'s anatomy, wherein the reflector oscillates in at least two directions to create a scan of the anatomy; a detector to detect radiation returned from the anatomy; and a controller to convert the detected radiation into a displayable image of the anatomy;
wherein the controller comprises an interface management component that is electrically coupled to a user interface, the reflector, and the radiation source, wherein the interface management component upon receipt of specified treatment parameters transmits signals to a source control to drive the radiation source to provide a requisite emitting radiation output for said treatment parameters. - View Dependent Claims (41, 42, 43, 44, 45)

46. A method for repairing or modifying an area of a patient'"'"'s anatomy comprising the steps of:
-
(a) directing at least a portion of a scanning beam assembly to an area of a patient'"'"'s anatomy, the scanning beam assembly comprising; a radiation source capable of emitting radiation; an optical fiber for directing the radiation from the radiation source toward a distal end of the scanning beam assembly in the form of a beam; a reflector that receives the beam of radiation from the optical fiber to direct the radiation onto the anatomy, wherein the reflector oscillates in at least two directions to create a scan of the anatomy with the radiation, the scan including sinusoidal angular deflections of the reflector yielding a bi-resonant or bi-sinusoidal scan path; a detector to detect radiation returned from the anatomy; and a controller lo convert the detected radiation into a displayable image of the anatomy that was scanned by the radiation directed thereto by the reflector;
