Patent number: 10702287Abstract: Method for producing a reamer such as a milling cutter intended to mill the acetabular cavity of a patient, the reamer including a rigid base with an interface for coupling to a tool holder, and including a cutter body which has a thin wall and is perforated and toothed. The rigid base is produced separately from the cutter body, by cutting out and drawing a first flat metal blank in a press.Type: GrantFiled: November 6, 2015Date of Patent: July 7, 2020Assignee: DEUXVENTORIO SÀRLInventor: Thomas Gradel

Patent number: 10398570Abstract: A cup and a temporary insert are respectively configured to be tightly press fitted into each other along their periphery. The temporary insert includes a through hole communicating outside with a free space between the outer surface of the temporary insert and the inner surface of the cup. In the through hole can be engaged the threaded end of an impactor, for manipulating the cup when it is being set. A syringe can be engaged, enabling a liquid under pressure to be injected into the free space, thus separating the temporary insert from the cup without any risk of damaging the inner surface of the cup. Thus, the cup can be securely manipulated when it is being set without any risk of damaging the inner surface of the cup.Type: GrantFiled: October 4, 2017Date of Patent: September 3, 2019Inventor: Thomas Gradel

Patent number: 9987139Abstract: A method for manufacturing a prosthetic hip acetabulum includes the following steps. First, one provides an insertion cup (1) having an inner concave receiving surface (3) having an opening surface (5) contained in an opening plane (P), and having an outer annular receiving structure (6). Next, one provides an installation and positioning insert (7) having a peripheral annular attachment structure (10) shaped to engage with the receiving surface (9) of the structure (6), fitting around that structure. Next, one heats the insert (7) in order to increase its size. Next, one fits the attachment structure (10) around the receiving surface (9) of the receiving structure (6). Finally, one cools the insert (7) to room temperature to reduce its size and achieve radial tightening of the attachment structure (10) on the outer annular receiving structure (6).Type: GrantFiled: August 3, 2015Date of Patent: June 5, 2018Assignee: INVENTORIO SAInventor: Thomas Gradel

Patent number: 9168143Abstract: A cotyle including a metallic insertion acetabular shell having an outer, essentially hemispherical, convex anchoring face formed in such a way as to be anchored in a cotyloid cavity of the pelvis of a patient, and a concave receiving face. The cotyle also includes a fixed definitive articular ceramic insert having an outer face engaging in the concave receiving face of the metallic insertion acetabular shell, and an inner receiving face including a concave, essentially hemispherical, articular surface for allowing the engagement and pivoting of a femoral prosthesis head or a mobile articular insert. The cotyle is packed in its assembled sterile state, with the definitive fixed articular ceramic insert engaged in the metallic insertion acetabular shell having a peripheral receiving structure that can receive means for fixing an impacter for positioning a cotyle and is designed in such a way that the impacter can be fixed to the cotyle in the presence of the definitive fixed articular ceramic insert.Type: GrantFiled: August 27, 2014Date of Patent: October 27, 2015Inventor: Thomas Gradel

Patent number: 8882849Abstract: An acetabular cup includes an articular insert (1) having a substantially semi-spherical articular cavity (1c), and a spherical head (2) engaged in the articular cavity (1c). A retaining device (10a) opposes the axial release (4) of the spherical head (2) from the articular cavity (1c) of the articular insert (1). For example, the retaining device can take the form of a back-tapered segment (10a) of the articular insert (1). The spherical head (2) is factory mounted in the articular insert (1), by temporarily heating the articular insert (1) and performing sterilization after assembly. In this way, the spherical head (2) retention capacity in the articular insert (1) is increased substantially in order to reduce the risk of luxation.Type: GrantFiled: October 12, 2010Date of Patent: November 11, 2014Assignee: Inventorio SAInventor: Thomas Gradel
