Device for mini-invasive ultrasound treatment of an object by a heat-isolated transducer
First Claim
1. A device for mini-invasive ultrasound treatment of an object comprising:
- at least one therapeutic ultrasound transducer arranged for treatment of the object by generating an ultrasonic field, the temperature focus of which is located in the object for heating thereof;
the therapeutic ultrasound transducer comprising an elongated probe defining a longitudinal direction and being adapted to be introduced into a body towards the object to be treated and which elongated probe comprises a front portion adapted to be located at, against, or in the object; and
wherein the elongated probe comprises at least one transmitter element for generating the ultrasonic field for treatment of the object and for transmitting the ultrasonic field through the front portion,wherein the transmitter element is arranged in a rear portion behind the front portion of the probe seen in the longitudinal direction, and wherein the front portion is configured to be thermally insulating, whereby during operation the transmitter element does not heat the front portion to a temperature sufficient to cause damage to the body,wherein the front portion of the probe comprises a focusing device for focusing the ultrasonic field generated by the transmitter element, andwherein the distance between the transmitter element and the focusing device for focusing the ultrasonic field in temperature focus is in the range of 0.5-20 centimeters.

Abstract
The present invention relates to a device for mini-invasive ultrasound treatment of an object. At least one therapeutic ultrasound transducer (2) is arranged for treatment of the object (5) by generating an ultrasonic field (3), the temperature focus (F) of which is located in the object (5) for heating thereof. The therapeutic ultrasound transducer (2) comprises a probe (10) adapted to be inserted into the body in the direction towards the object (5) and comprises a front portion (10a) adapted to be located at, against or in the object (5). Said probe (10) comprises at least one transmitter element (11) for generating said ultrasonic field (3). The transmitter element (11) for generating the ultrasonic field (3) is arranged behind the front portion (10a) such that the transmitter element (11) does not heat or substantially not heat the front portion (10a) when in operation.
