The present disclosure relates to an improved transcutaneous energy transfer (TET) system that generates and wirelessly transmits a sufficient amount of energy to power one or more implanted devices, including a heart pump, while maintaining the system's efficiency, safety, and overall convenience of use. The disclosure further relates one or more methods of operation for the improved system.

A method of fixating an implantable heart help device in a human patient is provided. The method comprises the steps of: cutting the skin of said human patient, dissecting an area of the body comprising bone, and fixating said implantable heart help device to said part of the body comprising bone.

A connector block for an implanted coil of a transcutaneous energy transfer system (TETS) includes a plurality of closed slots sized and configured to receive corresponding conductors of a powerline of the implanted coil. A plurality of open slots is included. The connector block being sized and configured to be coupled to the implanted coil.

In an implanted medical device system, an external power transmitter and methods for adjusting a rate of search pulse transmission by an external power transmitter of an implanted medical device system are disclosed. According to one aspect, a method includes detecting a condition of the external power transmitter, and selecting among rates of transmission of search pulses based on the detected condition.

A control circuit includes a pump shutdown module responsive to one or more inputs indicating at least from the group consisting of an operational error at the implantable blood pump and an adverse physiological state of a user of the implantable blood pump. The pump shutdown module ceases operation of the implantable blood pump in response to the one or more inputs. A pump restart module configured to resume operation of the implantable blood pump in response to a first pump restart input and a second pump restart input is included. A pump restart lockout module configured to initiate a pump lockout mode in response to a lockout input is included. The pump lockout mode prevents resumption of operation of the implantable blood pump in response to the first pump restart input and allows resumption of operation of the implantable blood pump in response to the second pump restart input.
