Abstract
Disclosed examples include technology for the detection and treatment of neotissue formation proximate an implantable stimulator. Neotissue formation can include ossification, scar tissue, soft tissue fibrosis, and other tissue growth. The neotissue formation can be detected by analyzing (e.g., using a machine-learning framework) stimulation data relating to the implantable stimulator. Neotissue formation characteristics can be analyzed to determine appropriate treatment actions for ameliorating the effects of neotissue formation.
Claims19
A system, comprising:
- a stimulator assembly having one or more electrodes;
- a biocompatible housing connected to the stimulator assembly;
- a stimulation source disposed in the biocompatible housing and configured to deliver electrical stimulation to target tissue of a recipient via the one or more electrodes;
- and
- one or more processors configured to:
- generate a current flow path using the one or more electrodes for stimulating tissue;
- measure one or more transimpedance matrices for the one or more electrodes based on the current flow path;
- determine neotissue formation characteristics relating to tissue growth proximate the one or more electrodes based on the one or more transimpedance matrices;
- determine a treatment modification instruction to modify stimulation parameters to account for the tissue growth;
- and
- apply the treatment modification instruction to modify ongoing stimulation provided by the apparatus.
8 more elements
A method comprising:
- determining a transimpedance matrix for a plurality of electrodes of an implanted stimulator;
- detecting neotissue formation characteristics proximate at least one of the plurality of electrodes based on the transimpedance matrix;
- and
- performing a treatment action based on the neotissue formation characteristics.
1 more element
A system comprising:
- one or more processors;
- and a non-transitory computer-readable memory comprising instructions that, when executed, cause the one or more processors to:
- obtain a transimpedance matrix for a plurality of electrodes of an implanted stimulator;
- determine neotissue formation characteristics relating to tissue growth proximate one or more electrodes of the implanted stimulator based on the transimpedance matrix, determine a treatment modification to modify stimulation parameters of the implanted stimulator to account for the tissue growth, and apply the treatment modification to the implanted stimulator to modify ongoing stimulation provided by the implanted stimulator.
