Publication number: 20240071593Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.Type: ApplicationFiled: October 24, 2023Publication date: February 29, 2024Inventors: Anna Leigh DAVIS, Scott M.

Patent number: 9814583Abstract: The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.Type: GrantFiled: May 8, 2007Date of Patent: November 14, 2017Assignee: Zimmer, Inc.Inventors: Dennis R. Aquilo, John E.

Publication number: 20150190234Abstract: A Midlay component includes a plastic bearing part and a metal tray part. The upper surface of the bearing part is dished in frontal and sagittal planes, to provide a bearing surface, such that in function, the femoral contact point will remain in the central region of the bearing surface. Hence the load-bearing on the plastic bearing part will be above the thickest portion in the central region. The metal tray part features a tray-bottom that enables retention of strong cortical and cancellous portion of a tibia in the treatment of osteoarthritis of a knee joint, and supports the plastic bearing part, with the rim of the metal tray part maintaining the position of the plastic bearing part and minimizing micromotions.Type: ApplicationFiled: January 2, 2015Publication date: July 9, 2015Inventors: Chih-Shing Wei, Peter S. Walker

Patent number: 8888857Abstract: A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.Type: GrantFiled: September 5, 2012Date of Patent: November 18, 2014Assignee: Zimmer, Inc.Inventors: John E. Meyers, George D. Letson, Russell Windsor, Vincent A. Webster, Bill N. Sisk, Bill H. Haywood, Adam M. Griner, Michael Cook, Rodney L. Bays, Jerry L. Aikins, Marvin Figueroa, Peter S. Walker

Publication number: 20120172995Abstract: A replacement knee implant has a femoral implant and a tibial implant, each of which are inset in a bone surface. The tibial implant is generally elongated with one end rounded and an opposite end conforming to the shape of the tibia, and is made of a metal alloy or a ceramic. The upper surface is dished while the lower surface is planar and can be parallel or sloped relative to the upper surface. The femoral implant for implementation in a femoral condyle is rounded such that, when implemented, the femoral implant is flush at the anterior and posterior sides and protruding away from the femur between the anterior and posterior ends. The femoral implant can have an elongated keel for extending into the femur, and can be made from a highly cross-linked polyethylene.Type: ApplicationFiled: March 13, 2012Publication date: July 5, 2012Applicant: NEW YORK UNIVERSITYInventors: Peter S.
