The needle-and-thread suturing process surgeons use to create anastomoses has been a staple in the OR, largely unchallenged for nearly a century. New developments in minimally invasive and endoscopic surgery, particularly in coronary bypass procedures, have created the need for a tissue-closure technique that can produce high-quality anastomoses in small spaces with limited visualization. As a result, anastomotic device technology, a long dormant area of product development, has become a hot subject at clinical meetings, and numerous companies, from major device firms to start-ups, are exploring a range of different approaches. Coalescent Surgical, a start-up, is one of the first to market in this area, with an anastomotic device that uses an approach different than its competitors--a proprietary self-closing clip that replaces traditional sutures. Coalescent's challenge: to gain acceptance from surgeons, who are notoriously slow adopters of new technology. The company is betting that the advantages of its device, combined with being first to market, will enable it to survive what appears will be a stampede of competitors, including major players that have superior resources and existing relationships with surgeons.

From the mid-16th century, when the father of modern surgery,
French military barber-surgeon Ambroise Pare, introduced the idea
of stitching wounds shut, the use of a needle and thread-like
material to connect tissue and close wounds has been a critical
part of the surgical armamentarium. Prior to Pare's discovery,
cauterization, either with hot irons or hot oil, was the primary
means to close wounds, a method that as likely took as many lives
as it saved. As with many early medical discoveries, Pare's
innovation was born out of necessity

Big pharma plans to invest billions of dollars in US manufacturing to avoid tariffs proposed by the Trump Administration. However, the implementation of these plans may be delayed due to regulatory complexities and rising costs from tariffs, potentially impacting drug prices for consumers.
Merck’s immuno-oncology blockbuster was the world’s best-selling drugs by revenues for the second year in a row, with an almost $12bn lead over its closest rival, Novo Nordisk’s GLP-1 drug Ozempic.
Good medical device regulation brings balance and builds bridges between healthcare stakeholders. It also accords equal priority to innovation and patient safety. A zero-risk policy cannot achieve these goals, says Christina Ziegenberg, BVMed’s head of regulatory affairs of six years.
