System for medical treatment
First Claim
1. A system for medical treatment comprising:
- a medical device to be placed in contact with a subject, the medical device comprisingan energy-receiving unit which comprises one or more rotors and/or one or more axial elements, anda separate hand-held device comprisinga housing, andan energy-transfer unit adapted to transfer energy via magnetic coupling to the energy-receiving unit of the medical device only when an energy-transfer position has been reached,a sensor adapted to detect positioning information of the energy-transfer unit relative to the energy-receiving unit, anda controller adapted to receive the positioning information from the sensor and to compare it to reference information related to the position to be achieved to determine from the comparison whether the energy-transfer position has been reached and if so, to enable transfer of a correct amount of energy to the medical device for the medical treatment and/or to inform the subject that the energy transfer position has been reached.

Abstract
The present invention refers to a system for medical treatment comprising a medical device and a separate hand-held device. The medical device comprises an energy-receiving unit and the separate hand-held device comprises a housing and an energy-transfer unit to transfer energy to be used at least in part for performing medical treatment to the energy-receiving unit of the medical device when the energy-receiving unit and the energy-receiving unit are in an energy-transfer position. The system further comprises at least one position sensor adapted to detect at least when the energy-transfer unit and the energy-receiving unit are in the energy-transfer position. The system further comprises a controller for controlling the energy-transfer unit such that the transfer of energy needed for medical treatment from the energy-transfer unit to the energy-receiving unit is enabled only when the energy-transfer unit and the energy-receiving unit are in the energy-transfer position.

11. A method for controlling, by a hand-held device, a medical device to be placed in contact with a patient for medical treatment, the method comprising the steps of:
-
detecting positioning information with a sensor when an energy-transfer unit of the hand-held device and an energy-receiving unit of the medical device are in an energy-transfer position by comparing the detected positioning information with reference positioning information; enabling the energy-transfer unit to transfer energy needed for medical treatment to the energy-receiving unit via magnetic coupling only when the energy-transfer position has been reached and/or after the patient has been notified that the energy-transfer position has been reached; transferring energy from the energy-transfer unit to the energy-receiving unit via magnetic coupling after the energy-transfer unit has been enabled; and transforming at least part of the transferred energy into rotational and/or axial mechanical force appropriate for performing the medical treatment. - View Dependent Claims (12, 13, 14)
