Introduction
Medtronic InterStim Bladder Stimulator is a medical device that is used to treat bladder control problems, such as overactive bladder and urinary incontinence. This innovative device provides relief to patients by delivering mild electrical pulses to the nerves that control the bladder. While InterStim has proven to be an effective treatment option for many patients, there have been concerns regarding its safety during magnetic resonance imaging (MRI) procedures. In this article, we will explore the safety of Medtronic InterStim Bladder Stimulator during MRI scans.
Understanding Medtronic InterStim Bladder Stimulator
Medtronic InterStim Bladder Stimulator is a small implantable device that consists of a battery-powered neurostimulator and a lead wire with electrodes. The neurostimulator is placed under the skin, usually in the buttock or lower back area, and the lead wire is implanted near the sacral nerves. These sacral nerves play a crucial role in controlling the bladder and pelvic floor muscles.
The device delivers electrical pulses to these nerves, which help to regulate the bladder function. It can be adjusted by a healthcare professional to meet the specific needs of each patient. InterStim is typically recommended for patients who have not responded well to other forms of treatment, such as medications or behavioral therapies.
The Concerns about MRI Safety
MRI scans are commonly used diagnostic procedures that use strong magnetic fields and radio waves to produce detailed images of the body’s internal structures. However, there have been concerns about the safety of Medtronic InterStim Bladder Stimulator during MRI scans.
One of the main concerns is the potential for the magnetic fields of the MRI machine to interfere with the functioning of the InterStim device. The electrical pulses delivered by the device could be disrupted or intensified, leading to discomfort or even injury to the patient.
Another concern is the heating effect that the MRI machine can have on the neurostimulator. The radiofrequency waves used in an MRI can cause the device to heat up, potentially damaging the surrounding tissues.
Medtronic’s Response and Safety Precautions
Medtronic, the manufacturer of InterStim, has conducted extensive research and testing to address the concerns regarding MRI safety. The company has developed an MRI SureScan technology, which is specifically designed for patients with InterStim devices.
MRI SureScan allows patients with InterStim devices to safely undergo MRI scans. The technology includes a special mode that adjusts the settings of the neurostimulator during the MRI procedure, minimizing the risk of interference or discomfort. The lead wire is also designed to be compatible with MRI scans, ensuring accurate imaging without compromising the device’s functionality.
It is important to note that not all InterStim patients are eligible for MRI scans. The decision to undergo an MRI should be made in consultation with the healthcare provider, who will evaluate the individual’s specific circumstances and determine the appropriateness of the procedure.
Benefits of MRI SureScan Technology
The introduction of MRI SureScan technology has provided several benefits for patients with Medtronic InterStim Bladder Stimulator:
- Accurate Diagnosis: MRI scans are valuable diagnostic tools that can provide detailed images of the body’s internal structures. With MRI SureScan technology, patients can benefit from this diagnostic modality without compromising the functionality of their InterStim devices.
- Enhanced Treatment Planning: For patients who require an MRI for treatment planning, such as those with suspected tumors or other conditions, MRI SureScan technology allows healthcare providers to accurately assess the condition and plan the appropriate treatment strategies.
- Improved Patient Management: MRI scans can be crucial for monitoring the progress of certain medical conditions. With MRI SureScan technology, patients with InterStim devices can undergo these follow-up scans safely and without concerns about device interference.
Conclusion
Medtronic InterStim Bladder Stimulator is a valuable treatment option for patients with bladder control problems. With the introduction of MRI SureScan technology, patients can now safely undergo MRI scans without compromising the functionality of their InterStim devices. It is essential for patients to consult with their healthcare providers to determine the appropriateness of MRI scans and ensure the safety and effectiveness of their treatment.
