Meru New Standards for Mental Health: Exclusive with CEO Kristian Ranta
2020 has been a challenging year in many ways, including for everyone’s mental health. The COVID-19 pandemic has caused a spike in mental health problems with cases tripling in the number of adults experiencing depression. Existing sentiments and situations drag on now into 2021. Today, the mental health care system is not very efficient and in many cases, broken, due to a shortage of access for patients and a lack of lasting results. Following the increasing mental health problem trends, a study published in JAMA Network Open in September 2020 offered one of the first nationally repre...

CorNeat Synthetic Cornea Implanted in First Patient
Eye surgeons at the Rabin Medical Center in Israel have successfully implanted the first artificial cornea into a bilaterally blind human patient. Once the bandages were removed, the 78 year old man was able to read and to recognize family members. This was all possible thanks to a device developed by CorNeat Vision, an Israeli firm, that consists of an optical component attached to a biocompatible material that resembles the human extracellular matrix. This material doesn’t biodegrade, but provides both the physical structure and biochemical signals to allow it to welcome fibroblasts and fuse with nearby native ...

Catheter Stimulates Lymphatic Drainage for Heart Failure Treatment: Interview with Eamon Brady, CEO of WhiteSwell
WhiteSwell, a medtech company based in Galway, Ireland, has developed a catheter system to treat acute decompensated heart failure (ADHF). ADHF is often treated using diuretics to remove excess fluid, but this doesn’t work for every patient and can have side-effects. This latest technology consists of a catheter with an impeller pump that is designed to stimulate lymphatic drainage, and thereby aid with decongestion without the need for diuretics. The catheter creates an area of low pressure where the largest lymph vessel, the thoracic duct, connects with the venous system near the heart. WhiteSwell claims ...

Imagio Opto-Acoustic Imaging for Breast Lesions FDA Approved
Seno Medical, a San Antonio, Texas firm, has won FDA approval to introduce its Imagio device that utilizes opto-acoustic imaging to help physicians identify whether breast lesions are benign or malignant. It is hoped that this non-invasive and radiation-free technology will help to reduce the number of biopsies that have to be performed. Opto-acoustic imaging combines ultrasound with laser optics to provide a combined view of tissue anatomy and the blood flow around it.

Endoscopic Surgery Using Steerable Lasers
Applying an energy source, such as a laser, to cut through or cauterize tissue is already widely used in external surgeries, such as laser eye surgery, but using this technology safely and accurately during minimally invasive internal procedures is difficult. Current endoscopic technology does not permit lasers to be steered and manipulated with sufficient precision. Now researchers at the Harvard Wyss Institute have developed a new technique to accurately steer a laser beam at the end of an endoscope for minimally invasive laser surgery. The approach relies on three small mirrors that move within a tiny cylinder to...

HARPOON System for Mitral Valve Repair: Interview with Daveen Chopra, Edwards Lifesciences
Degenerative mitral regurgitation occurs when the mitral valve prolapses, causing blood to leak back into the atrium every time the heart beats. The condition can be asymptomatic for many people, but for some it can cause a variety of issues, including fainting, pain, and shortness of breath. Currently, open-heart surgery is considered to be the gold-standard treatment for degenerative mitral regurgitation, but the procedure is obviously highly invasive. The HARPOON system developed by Edwards Lifesciences aims to provide mitral valve repair through a small chest incision, with the procedure occuring while the heart is ...

Electrical Stimulation Helps Regain Hand Function Post Spinal Cord Injury
Researchers at the University of Washington have trialed a minimally invasive electrical stimulation technique that has resulted in remarkable improvements in the hand and arm function of spinal cord injury patients. The approach involves sticking band-aid-like patches onto the back of the neck of patients to deliver electrical pulses, helping to stimulate the nerves below. Spinal cord injuries typically have serious consequences for patients in terms of mobility and independence in performing everyday activities.

Unfortunately, due to the COVID-19 pandemic this year the conference could only take place virtually. However, I was very fortunate to have had the opportunity to grab some time with one of the main keynote speakers thanks to the Dassault team who ...

Hydrogel Contact Lens Measures Biomarkers in Tears
Researchers at the Terasaki Institute in Los Angeles have developed a prototype of a contact lens that can assist with tear sampling for diagnostic purposes, and to also improve tear flow to potentially prevent dry eye disease. The hydrogel lens contains microchannels through which tears can travel and testing chambers where electrochemical and colorimetric tests can assess sodium levels and pH, respectively. Tears are a promising source for biomarkers, as they often contain levels of various analytes that are similar to those found in the blood. Examples of clinically relevant indicators found in tears include sodium, ...

Highly Realistic 3D Printed Human Hearts
Physical models of organs and tissues have many uses in clinical medicine, particularly when preparing for challenging surgeries. Naturally, the heart is commonly modeled using 3D printing to most closely mimic the nuances of unique patient anatomies. This is useful when preparing for procedures such as mitral valve repairs, but typically this is accomplished using printers that lay down layers of hard plastic or rubber that mostly only replicate the shape of the heart. The elasticity, on the other hand, is very much unlike that of real human hearts. A team at Carnegie Mellon University has now managed to print a 3D mod...

OtoSet Automatic Ear Cleaning Device FDA Cleared
SafKan Health, a firm based in Tucson, Arizona, won FDA clearance and is about to release its OtoSet automated ear cleaning system. Designed to address impacted earwax, which affects millions of people and often causes hearing loss, the OtoSet is a pair of headphones with irrigation and suction tips on the inside. These spray water onto the walls of the ear canal, rather than directly toward the ear drum, and suck out the residue at the same time. The residue is collected into a built-in container that is disposable and is replaced, along with the spray tips, with a brand new one between each patient. Alcohol wipes are ...

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 help to improve how free-flap reconstructions, replantations, peripheral nerve repairs and lymphatic surgery are performed. Surgeons operate on the Symani via its console that includes a built-in chair, manipulators, and a series of foot switches. The system relies on the...
