Medical device insertion with contour mapping

A method, comprising:

• advancing, as part of an implantation procedure into a human, at least a first portion of an electrode array into a cavity in a human during a first temporal period;
• providing information to a computer system, the provided information including spatial based data relating to the electrode array during the implantation procedure of the electrode array into the human;
• receiving information based on an evaluation by the computer system of the provided information, the evaluation having used the spatial based data to estimate a feature of the cavity, the received information being an indication of proximity between the electrode array and the feature of the cavity;
• and
• at least one of completing the implantation procedure including leaving the electrode array at its current location based on the received information or moving the electrode array based on the received information.

A method, comprising:

• obtaining data indicative of a plurality of different spatial locations of a first portion(s) of a medical device, the plurality of different spatial locations being locations during an insertion process of the first portion(s) into a human;
• analyzing the data;
• and
• at least one of:
• determining, based on the analysis, a location of a surface of a cavity in the human;
• or
• determining, based on the analysis, a spatial relationship between the surface of the cavity and a second portion, the second portion being one of another portion of the medical device located away from the first portion(s) of the medical device or a portion of another medical device.
