Patent number: 9308674Abstract: Implant body has a groove into which an outer ring is fitted. The body and ring are distinct solid parts both during and after assembly. A “flat” wall may be provided for the groove. The outer ring is annularly continuous and may be under tension, with the body under correspondent compression from the ring. An arthroplasty device can be provided.Type: GrantFiled: April 10, 2006Date of Patent: April 12, 2016Assignees: Signal Medical CorporationInventors: Louis A. Serafin, Jr., Nicholas H. Burlingame, Gerald J. Jerry, Jr.

Patent number: 9259508Abstract: Ceramic bodies can be made by providing an initial green body of ceramic; and machining the initial green body to provide a machined green ceramic body. Embedding the initial green body in an embedding mass can be avoided. The initial green body can be bisqued, infiltrated an adjuvant such as machining wax, removing the infiltrated body, and machining it. Highly detailed ceramic products can be generated. The machined green ceramic body may be fired and/or further processed to provide a more finished ceramic body. Examples include a femoral component for a posterior stabilized knee implant, a component body for an artificial rotation device containing knee implant prosthesis a dental implant or bridge, an ice skating blade, and so forth. Zirconia ceramics are advantageously employed, for an example, Mg-TTZ.Type: GrantFiled: September 7, 2005Date of Patent: February 16, 2016Assignees: Louis A. Serafin, Jr. Trust, Xylon, L.L.C.Inventors: Louis A. Serafin, Jr., Gerald J. Jerry, Jr., Nicholas H. Burlingame

Patent number: 9162008Abstract: Prosthetic implant or component therefor of a magnesium oxide stabilized transformation toughened zirconia (Mg-TTZ) ceramic can be made by providing a bisqued initial green body by compressing powder through a cold isostatic press and heating to a bisque stage. Then, without embedding it in an embedding mass, the bisque is machined to have a shape of the same proportions as the shape of, but larger than, the ceramic portion of a fired prosthetic implant or component product. Firing can provide the fired Mg-TTZ ceramic body product.Type: GrantFiled: June 25, 2012Date of Patent: October 20, 2015Assignees: Xylon, L.L.C.Inventors: Louis A. Serafin, Jr., Gerald J. Jerry, Jr., Nicholas H. Burlingame

Patent number: 9078754Abstract: Hard substance wear couple has materials of differing hardness forming surfaces for articulation in a joint implant prosthesis. For instance, a first articulating body can have a convex articulating surface, and a second articulating body can have a corresponding concave articulating surface that can articulate with the convex articulating surface of the first articulating body, in which the convex articulating surface of the first articulating body is harder than the corresponding concave articulating surface of the second articulating body. Ceramic materials are preferred.Type: GrantFiled: April 10, 2006Date of Patent: July 14, 2015Assignee: Signal Medical CorporationInventors: Louis A. Serafin, Jr., Nicholas H. Burlingame, Gerald J. Jerry, Jr.

Patent number: 8652211Abstract: Modular toe joint implant is a multi-piece device. Various sized piece(s), for example, head(s) and stem(s), can be provided in a kit or separately.Type: GrantFiled: January 24, 2007Date of Patent: February 18, 2014Inventors: Gerald J. Jerry, Jr., Louis A. Serafin, Jr.
