International Classification:

G09B 23/30
G09B 23/28

Abstract:

A set of simulator hardware and software provide a realistic training environment for pressure equalization tube delivery to a tympanic membrane using a semi-automated pressure equalization tube delivery device (“PETDD”). An anatomically realistic ear model is attached to a touch sensitive display so that the ear model aligns with a displayed virtual image of the middle ear, creating a realistic view through the ear canal of the ear model. A training PETDD and other devices of the simulator provide pressure and location data for the training PETDD as a trainee inserts the PETDD tip into the ear canal to rest against the virtual TM and simulate a PE tube delivery event. Resulting data is examined to determine whether the simulated delivery would have been successful if it had been a real scenario.

International Classification:

A61M 29/02

US Classification:

606192

Abstract:

A dilation system includes a balloon catheter and a puncturing assembly. The balloon catheter includes a shaft, a dilator coupled to a distal end of the shaft, and a lumen extending through the shaft and the dilator. The dilator is expandable from a collapsed state to an expanded state. The puncturing assembly includes at least one cutting member. The puncturing assembly is positionable within the lumen of the balloon catheter or along an exterior of the shaft when the puncturing assembly is in a first position. The puncturing assembly transitions to a second position to puncture the lumen of the balloon catheter and/or to puncture the dilator, to thereby drain fluid from the dilator.
