inomed micro-macro electrodes (MiMa):
Ideal for neurosurgery requiring electrophysiological identification of anatomic target points for stereotactic-functional interventions, including deep brain stimulation (DBS). The patented bipolar architecture allows for both recording and test stimulation to be carried out. The low capacitance of the electrodes enables the maximum spike amplitude to be measured. This results in an excellent signal-to-noise ratio for this type of brain surgery.
inomed MicroMove electrodes (IMM):
A combined electrode for the precise electrophysiological localization of anatomical target points in the human brain. The impedance of the MicroMove electrode is 1 MOhm, which means the electrode can be used with most commercially available recording systems.
inomed macro electrodes:
This electrode can be used to identify an anatomical target point by selective test stimulation during brain surgery. The electrode has a monopolar architecture and therefore it does not allow signal recording.
To enable precise removal of tissue during a stereotactic biopsy >>, inomed is the single source for all the latest biopsy instruments for brain surgery – these include forceps and probes (Sedan-type and Backlund). Single-use products and reusable versions are available.
We support the following stereotactic systems for brain surgery (the choice of system determines the working length of the biopsy instruments):
The open stereotactic system (OSS) is a system for frame-based stereotaxy in brain surgery. The open ceramic ring is fixed rigidly to the patient's head and remains in place throughout the entire procedure. The stereotactic coordinates from the tomographic images can be transferred to the ceramic ring-mounted stereotactic systems and allow for a targeted intervention.
For neurosurgical and radiosurgical procedures and treatments, the goal is to achieve - as closely as possible - a preoperatively planned target point for brain surgery. Imaging procedures, such as computer tomography or magnetic resonance imaging, can provide images of the patient during brain surgery. With the help of modern computer software, such as inomed iPS planning software, it is possible to view this tomogram either individually or as a three-dimensional image and to analyze the target for brain surgery.
The inomed open ceramic ring ensures minimum interference and maximum artefact reduction when imaging is used, and this is particularly the case with MRI. The semi-open architecture means a part of the patient’s face is not covered. This increases patient comfort, especially during brain surgery while awake.
Suitable for all types of neuro- or radiosurgical brain surgery that requires a stereotactic procedure.
The open ceramic ring has been specially designed for use with imaging in modern MRI scanners. Often used in compact head coils for brain surgery (e.g. Siemens Vision), it limits the size to an outer diameter of 260 mm. The concept of the open ring still allows access to the ENT region of the patient. In order to achieve the best possible MR imaging and correct for artefacts during brain surgery, a ceramic material is used. This is a high-performance ceramic material. It is characterized by its high resistance to mechanical loads during normal hospital operation and is largely resistant to the effects of daily steam sterilization.
