(30 days)
The REMEDY Acetabular Cup 46mm ID/54mm OD consists of an acetabular cup that is indicated for temporary use (maximum 180 days) as an adjunct to total hip replacement (THR) in skeletally mature patients undergoing a two-stage procedure due to a septic process.
The REMEDY Acetabular Cup 46mm ID/54mm OD is positioned into the acetabular cavity following removal of the existing acetabular and femoral components and radical debridement. The device must be combined with the REMEDY Hip Spacer using the REMEDY 46mm Modular Head when gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s), or the REMEDY SPECTRUM GV Hip Spacer using the REMEDY SPECTRUM GV 46mm Modular Head when gentamicin and vancomycin are the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s). The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection).
The REMEDY Acetabular Cup 46mm ID/54mm OD is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g., resection arthroplasty, etc.).
The REMEDY Acetabular Cup is a temporary spacer device available in a single size, intended to be combined with either the REMEDY Hip Spacer with 46mm Modular Head or the REMEDY SPECTRUM GV Hip Spacer using its 46 mm Modular Head.
The REMEDY Acetabular Cup is a sterile, single-use device intended for temporary use (maximum 180 days) as joint replacement. The device is made of fully formed polymethylmethacrylate (PMMA), which is radio-opaque and contains gentamicin.
The REMEDY Acetabular Cup and REMEDY or REMEDY SPECTRUM GV Hip Spacers provide a functional-mechanical mode of action; the system provides patients a temporary implant allowing for a natural range of motion and partial weight-bearing during treatment. The system is designed to preserve soft tissue to prevent further complications, such as muscular contraction, and to facilitate the subsequent joint replacement procedure. The REMEDY Acetabular Cup is protected from bacterial adhesion due to the presence of gentamicin.
This is a 510(k) premarket notification for a medical device called the "REMEDY Acetabular Cup." This document does not describe a study that validates an AI/ML powered medical device. It instead details the equivalency of the REMEDY Acetabular Cup to predicate devices through physical performance testing and engineering analysis, not through a clinical or algorithmic performance study involving a test set, ground truth, or expert readers.
Therefore, I cannot provide the information requested in the format of acceptance criteria and study proving device meets the criteria, as this document does not contain that type of information for a device that relies on algorithmic performance.
The document discusses:
- Device Name: REMEDY Acetabular Cup
- Regulation: 21 CFR 888.3360 (Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis)
- Product Codes: KWL, KWY
- Indications for Use: Temporary use (maximum 180 days) as an adjunct to total hip replacement (THR) in skeletally mature patients undergoing a two-stage procedure due to a septic process. It requires combination with specific Hip Spacers (REMEDY Hip Spacer or REMEDY SPECTRUM GV Hip Spacer) depending on the appropriate antibiotic (gentamicin or gentamicin and vancomycin).
- Device Description: Sterile, single-use, made of polymethylmethacrylate (PMMA), radio-opaque, contains gentamicin. Provides functional-mechanical mode of action, allows natural range of motion and partial weight-bearing.
- Predicate Devices: REMEDY Acetabular Cup (K173967) and REMEDY SPECTRUM GV Hip Spacer (K172906).
- Substantial Equivalence: Demonstrated through performance testing (static and fatigue strength of resin, range of motion, surface roughness, antibiotic release kinetics) and engineering analysis of wear. Endotoxin testing also performed.
The relevant section regarding acceptance criteria and performance would be "Performance testing... to support its substantial equivalence" on page 5. However, this refers to mechanical and material performance, not the performance of an AI/ML algorithm.
§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
