Implantable Pump Delivers Chemotherapy to Brain Tumors

Researchers at Linköping University, Sweden, and the Medical University of Graz, Austria have developed an electrical pump that can precisely deliver chemotherapeutic drugs into the brain. The technology is conceived as being implantable into brain tumor resection sites to deliver localized chemotherapy over extended periods. It is hoped that (Read more...)

3D Printed Microfluidic Bioreactor for Brain Organoid Culture

Researchers at MIT and the Indian Institute of Technology Madras have developed a 3D-printed microfluidic bioreactor that can be used to culture and study brain organoids. The tiny self-organizing nodules of brain tissue are very useful in studying neurological disease and the effects of drugs. However, the bioreactors used to grow brain organoids (Read more...)

Medical Robotics and The Future of Surgery: Interview with Tracy Accardi, VP of R&D at Medtronic

Medtronic has been a key player in the minimally invasive surgery space for the last few decades, and has made great strides more recently in robotic surgery with last year’s acquisition of Digital Surgery. As a quick reference point: despite the many benefits of robotic-assisted surgery (RAS), only 3% of surgeries around the world are [&hell (Read more...)

Clear Cranial Implant Allows Ultrasound Imaging of Brain: Interview with CEO of Longeviti Neuro Solutions

Longeviti Neuro Solutions, a medtech company based in Maryland, has announced that its ClearFit cranial implant has been cleared by the FDA for post-surgery ultrasound imaging. The clear implants are used for cranial reconstruction after brain surgery, and are custom-made for each patient. The company uses patient CT scans and 3D printing to produc (Read more...)

Spinal Cord Stimulators Manage Pain without Tingling

Boston Scientific is releasing in the United States its Wavewriter Alpha line of spinal cord stimulators. The four Wavewriter Alpha pain management devices provide Bluetooth connectivity, allow patients to still be scanned under MRI, given certain precautions, and offer so-called Fast Acting Sub-perception Therapy (FAST). FAST is exciting because i (Read more...)

3D Imaging Illuminates Internal Structure of Brain Spheroids

Researchers at the Wyss Center in Geneva and collaborators have developed novel imaging and labeling techniques to view the internal structure of brain spheroids, and observe the morphology of single neurons in 3D. Brain spheroids, which the researchers term “mini brains,” are a cluster of different types of brain cells, and are culture (Read more...)

Radiotherapy to Prevent Recurrence Post Brain Tumor Excision: Interview with Matthew Likens, President and CEO of GT Medical

GT Medical Technologies, a company based in Arizona, has developed the FDA-approved GammaTile system, which can provide localized radiation therapy for brain tumor excision sites. Its goal is to reduce tumor recurrence and enhance patient survival. The treatment consists of radiation seeds encased in a collagen substrate. These are easy to place at (Read more...)

Symani Microsurgical System Cleared in Europe

Medical Microinstruments (MMI), a company based outside of Pisa, Italy, won the European CE Mark of approval for its Symani robotic surgical system. The product provides 7-20X scaling of hand movements, automatically removing tremors to allow for safe microsurgical and supermicrosurgical procedures. It is hoped that this impressive new device can h (Read more...)

Portable Surgical Robot for Minimally Invasive Procedures: Interview with John Murphy, CEO of Virtual Incision

Virtual Incision, a company based in Lincoln, Nebraska, has developed the miniaturized in vivo robotic assistant (MIRA) platform to perform minimally invasive abdominal surgeries, such as colon resections. Conceived as a small and accessible surgical robotic support device, the miniaturized system is considerably less expensive than current robotic (Read more...)

High Resolution Ultrasound for Precise Tumor Ablation

Researchers at the Max Planck Institute and the University of Stuttgart in Germany have developed a method to create high-resolution ultrasound fields, a capability which may improve the effectiveness of ultrasound therapies and tailor them for individual patients. The technique involves passing ultrasonic waves through water, where hydrogen bubble (Read more...)

Wireless Brain Implant to Give Sight to Blind

Scientists in Australia are gearing up for clinical trials of a brain implant that may restore limited sight in blind people. Developed at Monash University in Melbourne, the Gennaris system involves bypassing the eye completely and targeting the vision center of the brain. A person would wear a pair of glasses outfitted with a camera […]

Origami Surgical Manipulator to Perform Microsurgeries

Robotic surgical assistants, such as the da Vinci systems from Intuitive Surgical, are now routinely used during laparoscopic procedures to improve operative precision, flexibility, and to manipulate multiple tools at once. Such devices can be quite complex inside and so they tend to be quite large, often taking up much of the space of an [… (Read more...)

TIGERTRIEVER XL Cleared in EU to Remove Large Stroke Clots

Israel’s Rapid Medical has won European regulatory clearance to introduce its TIGERTRIEVER XL device for removing large ischemic stroke-causing clots from intracranial vessels. The company calls its line of devices “stentrievers,” as these look and operate similar to stents but can retrieve clots out of the body. The TIGERTRIEVER (Read more...)

Mechanically Stimulating Neurons Using Magnetic Nanodiscs

Electrical stimulation and chemical pharmaceuticals are the two ways that doctors and scientists routinely use to manipulate neural cells. Chemicals have their side effects, are slow to take effect, and are usually systemically delivered, while electrical stimulation usually requires invasive wires, is limited in its resolution, and is nearly impos (Read more...)
