Abstract
Methods and devices for sealing an orifice are provided. A sealing element is inserted into an orifice. A fluid is transferred into the sealing element. Fluid transfer into the sealing element is restricted when a pressure in the sealing element is greater than a threshold value.
Claims18
A method of sealing an ear canal comprising:
- inserting a sealing element into an ear canal;
- transferring a fluid into the sealing element to seal the ear canal;
- measuring a change of pressure in the sealing element responsive to the transferring of the fluid into the sealing element;
- and
- activating a valve to prevent fluid transfer into the sealing element when the measured change of pressure is greater than a threshold value.
2 more elements
An ear canal sealing device comprising:
- a sealing element configured to be inserted into an ear canal;
- a fluid transfer element configured to pass transfer fluid into the sealing element to seal the ear canal;
- a pressure measurement device configured to measure a change of pressure in the sealing element responsive to the transferring of the fluid into the sealing element;
- and
- a valve configured to be activated to prevent fluid transfer into the sealing element when the measured change of pressure is greater than a threshold value.
