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 application discloses a method and system for rapid acquisition of ECAP recordings. The system includes a receiving unit configured to receive, corresponding to an electrode of an implanted electode array, a stored prior individual value from a plurality of stored prior individual values of ECAP / an ECAP prior growth function, the plurality of stored prior individual values or the ECAP prior growth function being obtained at a previous session; and a processing unit configured to process the received prior individual value / ECAP growth function to determine a stimulus signal value corresponding to the received individual value / a selected point on the ECAP prior growth function, instruct a signal delivery unit to provide to the electrode a first stimulus signal comprising a first level that is same or above said stimulus signal value, and determine a resulting ECAP generated in response to said first stimulus signal.

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...
