Enabling devices outperform substituting devices commercially
Devices that automate a task a surgeon already performs competently face the surgeon as a benchmark, and at roughly 45 times the cost of a conventional suture the comparison rarely favours them. Devices that made procedures possible face no benchmark at all. Endoscopic sleeve gastroplasty exists because a suturing system can place full-thickness sutures through a flexible scope, and suture-mediated large-bore closure exists because transcatheter access must be closed percutaneously. Both compound well above the market rate while laparoscopic substitution devices grow at 6.8%. The distinction predicts commercial outcomes here better than any technical property does.
