Embodiment Construction

[0081] The detailed description given below in conjunction with the accompanying figures serves as a description of non-limiting embodiments of methods and systems according to the present invention.

[0082] As an illustration, a cochlear implant is defined as generally comprising: i) an external portion comprising an input transducer for receiving an input acoustic signal from the user's environment and providing a corresponding electrical input signal, for processing the electrical input signal and according to the processed A signal processing unit for determining the pulse sequence for electrode stimulation from an input acoustic signal; ii) a (usually wireless, e.g. inductive) communication link for simultaneously transmitting information about the stimulation sequence and energy to the implant; iii) the implant An implant section that enables stimulation to be generated and applied to an electrode array that can be implanted at various locations in the cochlea to enable ...

Abstract

The present application discloses a method and system for rapidly obtaining evoked compound action potential records, wherein the system includes: a receiving unit configured to receive from a plurality of stored evoked compound action potential ECAP prior single values ​​corresponding to implanted electrode an ECAP previous growth function of an electrode of the array, a stored prior unique value, or a stored plurality of previous ECAP single values ​​obtained in a previous session; and a processing unit configured to process the received prior single value or ECAP growth function to determine a stimulus signal value corresponding to a selected point on the received single value or ECAP previous growth function, the instruction signal transmission unit will comprise the same A first stimulation signal at a first level having the same or higher value of the stimulation signal is provided to electrodes, and an evoked compound action potential generated in response to the first stimulation signal is determined.

Description

technical field [0001] The present invention generally relates to methods and systems for obtaining evoked compound action potential (ECAP) recordings. In particular, the present invention relates to methods and systems for rapidly obtaining ECAP records for patients whose ECAP growth functions have previously been obtained. The methods and systems of the present invention may be used in conjunction with cochlear implants (CI) in hearing impaired persons. Background technique [0002] In general, there is a need to obtain data from implanted components of cochlear implants. Such data collection enables detection and confirmation of proper functioning of the device, as well as optimization of stimulation parameters to suit the needs of the individual recipient. This includes data on how the auditory nerve responds to stimuli. [0003] Typically, following surgical placement of a cochlear implant, the implant is fitted or customized to meet the needs of a particular recipie...
