As it develops a new metastasis-on-a-chip device based on microfluidic chip technology that provides a platform to capture and study highly metastatic cancer cells, Mettactics Ltd. is in the process of raising financing to develop its product to empower precision medicine. Founded in 2019, Hong Kong-based Mettactics developed a microfluidic device that can capture metastatic cells and carry out clinical tests to predict the drug response of patients based on the cells’ genetic signature.

In its second approval this month from the U.S. FDA, Avita Medical Inc.’s Recell system received premarket approval for the repigmentation of stable depigmented vitiligo lesions. The approval marks the first therapeutic device offering a one-time treatment for vitiligo at the point of care. Using the device, a clinician prepares and delivers autologous skin cells from pigmented skin to stable depigmented areas.

The Vanta device by Medtronic plc, provides relief from pain for thousands of patients, but the Vanta might also feel the pain when the patient is undergoing cardioversion. According to a field safety notice from Dublin-based Medtronic, two patients in Europe have undergone explant procedures for the device due to damage sustained during cardioversion, but the company urges physicians to pay heed to the labeled indication, which recommends that the device be temporarily reprogrammed to reduce the risk of damage to the device, an action that Medtronic indicated should ward off any such issues.

The U.S FDA 510(k) clearance for Corneat Vision Ltd.’s Everpatch is a “safety stamp” for the product, and the “first step’ in the deployment of Corneat’s synthetic tissue substitute technology, which could displace the use of donor and processed tissue, Almog Aley-Raz, CEO of Corneat, told BioWorld. The Corneat Everpatch, for use in ophthalmic surgeries, is the first non-degradable material that seamlessly embeds itself with surrounding tissue avoiding foreign body response often triggered by implanted devices, Aley-Raz claimed.

Whoever said beauty is only skin deep hasn’t looked below to see what Sientra Inc. has made available there recently. The medical aesthetics company now boasts the only tissue expander cleared in the U.S. for exposure to magnetic resonance imaging, an important screening tool for breast reconstruction patients. Sientra’s CTO Denise Dajles told BioWorld the newly cleared Allox2 Pro Tissue Expander builds on the original expander also cleared by the FDA. “No other expander in the market has an MRI compatibility indication because they are based on a metal, i.e., metallic ports and big magnets in them,” Dajles explained.

General Stim Inc.’s implanted sacral nerve stimulation (SNS) system was approved in China to treat individuals with certain bladder and bowel conditions. Hangzhou-based General Stim’s SNS system consists of a sacral nerve stimulator, an extension lead and an electrode.

The U.S. FDA’s citizen’s petition process doesn’t always yield the desired outcome, but the agency must nonetheless respond to these petitions. Sonex Health Inc., has petitioned the FDA to rethink a proposal to reclassify the company’s SX-One device for treatment of carpal tunnel syndrome, an unusual instance in which a medical device maker has resisted a proposal to make a device exempt from regulatory requirements.

Avenda Health Inc. reported new study results showing its Unfold AI platform, which uses artificial intelligence (AI) to map a tumor’s location within the prostate, encapsulates all of the clinically significant cancer present in the gland more effectively than standard care.
