Abstract

Systems and methods for treating a patient having a head with a first ear and a second car, function by mounting a support structure to the head of the patient; aligning the support structure with a target tissue in an ear canal of the first ear; stabilizing the support structure relative to the target tissue by injecting a material into the canal and hardening the material; and actuating a device while the device is supported by the support system so that the device therapeutically remodels the target tissue of the first ear.

Claims

1-8. -8. (canceled)

9. A system for treating a patient, the patient having a head with a first ear and a second ear, the system comprising:

a support structure engageable with the head of the patient so that the support structure and head define a receptacle therebetween;

an material receivable by the receptacle, the injectable material having a workable state allowing adjustment to alignment between the support structure and a target tissue of the first ear, and a hardened state for stabilizing the support structure relative to the target tissue; and

a device mountable to the support structure, the device actuatable so as to therapeutically remodel the target tissue of the first ear.

10. The system of claim 9, wherein the material comprises impression material.

11. The system of claim 9, wherein the target tissue comprises a tympanic membrane, and further comprising an image capture device supported by the support structure and oriented so as to image the target tissue of the first ear so that alignment of the support system with the ear can be performed with reference to a display of the captured image.

12. The system of claim 11, wherein the support structure comprises a fluid barrier configured for retaining a fluid in the ear canal in fluid communication with the tympanic membrane, the fluid barrier separating the material from the fluid.

13. The system of claim 12, further comprising an iontophoresis electrode supported by the support structure, the electrode suitable for applying a therapeutic agent of the fluid to the target tissue.

14. The system of claim 13, further comprising an optical distance measuring system receivable by the support structure so as to measure a distance from the support structure to the tympanic membrane.

15. The system of claim 14, wherein the support structure has an interface, and wherein the interface replaceably receives a measurement module including the measuring system, a treatment module including the treatment device, and/or an iontophoresis module including an iontophoresis electrode.
