Rapid Compression Device to Prevent Deep Vein Thrombosis

Researchers at Penn Medicine have developed a wearable sleeve that provides rapid pulsatile compression, and aims to mimic the compression our calf muscles experience during walking. The technology, being commercialized by Osciflex, a spin out from Penn Medicine, is intended to prevent deep vein thrombosis in patients who are bed-bound for long per (Read more...)

Tendon-Inspired Sutures Protect Fragile Tissues

Researchers at McGill University in Canada have developed bioinspired sutures that mimic the structure of human tendons. The gel-covered sutures are slippery and tough, reducing the damage caused by conventional sutures when used on soft tissues. Interestingly, the gel surface of the sutures may allow for advanced applications such as drug delivery (Read more...)

Micro-Aneurysm-On-A-Chip to Model Vascular Disease

An international research collaboration, including teams from Nanyang Technological University, Singapore (NTU Singapore), Brown University, and MIT, has developed an AI platform that can assess blood flow characteristics through microvasculature. The system relies on a microfluidic chip that mimics vascular disease, in this case a micro-aneurysm i (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...)

Placental Allografts for Diabetic Foot Ulcers: Interview with Tim Wright, CEO of MiMedx

MiMedx, a medtech company based in Georgia, has developed EpiFix, an off-the-shelf allograft system for the treatment of diabetic foot ulcers. The grafts are made using donated human placental tissues that are obtained from consenting mothers during caesarean section procedures. The tissues then undergo a proprietary processing procedure to clean t (Read more...)

Cios Flow Mobile C-Arm from Siemens FDA Cleared

Siemens Healthineers just announced FDA clearance to introduce its Cios Flow mobile C-arm in the United States. Developed for use in orthopedics, vascular surgery, trauma, spinal surgery, and other fields, it’s intended to be a general purpose C-arm that can be easily used in a variety of cases. The Cios Flow is a relatively compact [… (Read more...)

Nanodroplets and Ultrasound to Drill Through Blood Clots

Penetrating compacted and extensive blood clots has been one of the main challenges of vascular surgery. Various catheter-based devices have been invented and are in use today, but many patients present with plaques that are just too difficult even for the finest existing devices. Now, researchers at North Carolina State University and University o (Read more...)

CoolSeal for Quick and Safe Vessel Sealing Unveiled

Bolder Surgical, a Louisville, Colorado firm previously called JustRight Surgical, is starting the new year by releasing the CoolSeal vessel sealing platform. The initial product offerings are the CoolSeal Trinity device, a 5mm laparoscopic sealer, and the 3mm CoolSeal Mini, both of which work with the CoolSeal generator. The CoolSeal Trinity (pict (Read more...)

PREVENA RESTOR AXIO•FORM Negative Pressure Wound Therapy: Interview with Dr. Ronald Silverman, 3M’s Chief Medical Officer

3M recently announced a new negative pressure wound therapy system called PREVENA RESTOR AXIO•FORM Incision Management System, which has been available since August. The new system expands the amount of time that negative pressure can be applied to a total of 14 days, with a dressing change at 7 days. The included disposable dressings are [&he (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...)
