Application No. 19114921 was filed September 28, 2023.
What changed
USPTO published patent application US20260090890A1 for a device designed to anchor a shoulder prosthesis in a reverse configuration. The invention comprises a baseplate with a first convex bottom surface and second concave top surface, peripherally bounded by a truncated-cone or cylindrical surface. A central pin protrudes from the baseplate's bottom surface and defines an axially pass-through inner duct with a main diameter and a secondary smaller diameter, containing a helical cavity in the inner wall.
Patent applications do not create immediate compliance obligations for manufacturers. However, medical device companies developing shoulder prostheses should review this application to assess potential competitive implications for their own products. The application's publication does not grant patent rights; the applicant would need to prosecute the application through USPTO examination to obtain granted claims.

Abstract
A device for anchoring a shoulder prosthesis in a reverse configuration includes a baseplate delimited at the bottom by a first at least partially convex surface, and at the top by a second concave surface, opposite the first surface, and peripherally by a third truncated-cone or cylindrical surface; and a central pin, protruding from the first surface at a first end thereof, and defining an axially pass-through inner duct having at least one main diameter. The central pin has a second free end, opposite the first end. The duct has a helical cavity made in the inner wall delimiting the duct, open towards the inside of the duct and extending along the length of the duct. The inner duct has a secondary diameter smaller than the main diameter, and the helical cavity has a diameter larger than the main diameter of the inner duct.
