Problems solved by technology

Indeed, as shown in previous clinical trials (Carpentier & al., "Real-time Magnetic Resonance-Guided Laser Thermal Therapy of Metastatic Brian Tumors", Neurosurgery, 63 ONS Suppl 1:21-29, 2008), very high temperature treatment of tumors can lead to Severe increase in tumor size (mass effect)
This increase in volume is in most cases uncoordinated with the maintenance of surrounding normal tissue and will limit the development of this ultra-sonic minimally invasive therapeutic system

Embodiment Construction

[0064] Figure 1 is a schematic view of a medical device 1 comprising a traditional type of magnetic resonance imaging (MRI) system 2, which is adapted to be operated particularly in a thermal imaging mode, in which a patient 3 is introduced, for example lying on a suitable bed 4 on.

[0065] The medical device 1 further includes a computer system 5 connected to a magnetic resonance imaging device to receive data from the magnetic resonance imaging device, and the data can construct an anatomical analysis and / or thermal magnetic resonance imaging of the patient 3.

[0066] The medical device further includes an MRI-compatible probe 6 inserted into the patient's body percutaneously, and is operatively connected to a computer system 5. The probe 6 is electrically connected to the computer system 5 via, for example, an MRI compatible cable. The compatible cable is, for example, a coaxial cable, which itself is known to the public and will not be repeated here.

[0067] As shown schemati...

Abstract

The percutaneous probe, made in MRI - compatible materials, comprises: a body percutaneously inserted into the tissue of a patient's body organ (8) having a region (10) to be analyzed, treated and monitored during a single medical procedure; at least one information collection sensing device (30,33,34); treatment application transducers (30) 360 DEG disposed to emit focused or defocused therapeutic ultra-sound waves. The computerized system comprises a parametrizable command device (50) adapted to simulate then command a generation of the therapeutic ultra-sound waves, and to monitor the treatment by thermal MRI images.

Description

Technical field [0001] The present invention relates to a medical system including a percutaneous probe, and the use of the medical system. Background technique [0002] In medicine, low-intensity ultrasound is widely used in the diagnosis process, namely ultrasound echography. For 10 years, high-intensity ultrasound has proven to be an effective method for inducing tissue necrosis through extremely high heat therapy used in the treatment process. Various therapeutic probes have been designed for minimally invasive treatment procedures, and these probes can be divided into two groups: external probes and internal probes. [0003] The external probe is designed to imitate the shape of the patient's body surface, and the ultrasound transmitter is arranged in a concentric manner to optimize the focus of the ultrasound. [0004] Internal probes or interstitial probes can be inserted into the patient's body. There are three main types of them: intraluminal probes, intravascular probes o...
