The document describes a physical medical device (modular spacers for hip and knee) made of PMMA with gentamicin. There is no mention of software, algorithms, or data processing that would indicate the use of AI or ML. The performance studies focus on material properties, mechanical testing, and antibiotic elution, not algorithmic performance.
Yes.
The device descriptions explicitly state its intended use as an "adjunct" to total hip/knee replacement in patients with septic processes, to "preserve soft tissue to prevent further complications," and to "facilitate the subsequent joint replacement procedure," all of which indicate a therapeutic purpose.
No
Explanation: The device is described as a temporary joint replacement spacer intended for therapeutic use in patients undergoing a two-stage procedure due to a septic process, not for diagnosing a condition.
No
The device description clearly states it is a physical implant made of polymethylmethacrylate (PMMA) and contains gentamicin. It describes physical components (head, stem, femoral, tibial components) and their mechanical function. There is no mention of software as a component of the device itself.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The provided text clearly describes the Hip and Knee Modular Spacers as implantable medical devices used in surgical procedures (total hip/knee replacement) to temporarily replace joint components. Their function is mechanical and pharmacological (releasing gentamicin).
- Lack of Diagnostic Activity: The device does not analyze biological samples or provide diagnostic information about a patient's condition. Its purpose is therapeutic and supportive during a two-stage surgical procedure for infection.
Therefore, the Hip and Knee Modular Spacers fall under the category of implantable medical devices, not in vitro diagnostics.

Intended Use / Indications for Use
Hip Modular Spacer: The Hip Modular Spacer, which consists of a modular head and stem, 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 and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organisms.
The head and stem components are inserted into the acetabular cavity and femoral medullary canal, respectively, following removal of the existing acetabular and femoral components and radical debridement. The device is intended for use in conjunction with systemic antibiotic therapy (standard treatment approach to an infection).
The Hip Modular Spacer 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, fusion etc.).
Knee Modular Spacer: The Knee Modular Spacer, which consists of a modular femoral, tibial insert component, is indicated for temporary use (maximum 180 days) as an adjunct to total knee replacement (TKR) in patients undergoing a two-stage procedure due to a septic process and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s).
The device is applied on the femoral condyles (femoral component) and on the tibial plate (tibial component) following removal of the existing implant and radical debridement. The use of the tibial insert component is optional, when a large tibial defect is present. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection).
The Knee Modular Spacer 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, fusion etc.). Because of the inherent mechanical limitations of the device materials (gentamicin/polymethylmethacrylate), the device is only indicated for patients who will consistently use traditional mobility assist devices (e.g., crutches, walkers, canes) throughout the implantation period.

Device Description
The Modular Spacers are sterile, single-use devices intended for temporary use (maximum 180 days) as joint replacements. The Hip Modular Spacer is composed of two components (a head and a stem) that are intended to be used together to form a temporary hip spacer; the components are available in a range of sizes. The Knee Modular Spacer is composed of three independent components (a femoral component, a tibial component and a tibial insert component) that are intended to be used together to form a temporary knee spacer; the components are available in a range of sizes.
The devices are made of fully formed polymethylmethacrylate (PMMA), which is radioopaque, and contains gentamicin and color additives to give a green color.
The Modular Spacers provide a functional-mechanical mode of action; they provide patients a temporary implant allowing for a natural range of motion and partial weight-bearing during treatment. They are designed to preserve soft tissue to prevent further complications, such as muscular contraction, and to facilitate the subsequent joint replacement procedure.

The devices are made of fully formed polymethylmethacrylate (PMMA), which is radioopaque, and contains gentamicin and color additives to give a green color.
The Modular Spacers provide a functional-mechanical mode of action; they provide patients a temporary implant allowing for a natural range of motion and partial weight-bearing during treatment. They are designed to preserve soft tissue to prevent further complications, such as muscular contraction, and to facilitate the subsequent joint replacement procedure.
INDICATIONS FOR USE AND INTENDED USE ട്
The Modular Spacers have the following indications for use statements.
Hip Modular Spacer
The Hip Modular Spacer, which consists of a modular head and stem, 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 and where gentamicin is the most uppropriate antibiotic based on the susceptibility pattern of the infecting micro-organisms.
The head and stem components are inserted into the acetubular cavity and femoral medullary canal, respectively, following removal of the existing acetabular and femoral components and radical debridement.
2
The device is intended for use in conjunction with systemic antibiotic therapy (standard treatment approach to an infection).
The Hip Modular Spacer is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implunted or another appropriate treatment performed (e.g. resection arthroplasty, fusion etc.).
Knee Modular Spacer
The Knee Modular Spacer, which consists of a modular femoral, tibial insert component, is indicated for temporary use (maximum 180 days) as an adjunct to total knee replacement (TKR) in patients undergoing a two-stage procedure due to a septic process and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s).
The device is applied on the femoral component) and on the tibial plate (tibial component) following removal of the existing implant and radical debridement. The use of the tibial insert component is optional. when a large tibial defect is present. The device is intended for use in conjunction with systemic antimicrobial untibiotic therapy (standard treatment approach 10 an infection).
The Knee Modular Spacer 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, fusion etc.). Because, of the inherent mechanical limitations of the device materials (gentamicin(polymethylmethacrylate), the device is only indicated for patients who will consistently use traditional mobility assist devices (e.g., crutches, walkers, canes) throughout the implantation period.
This is the same intended use as the predicate devices. The Garventis Modular Spacers and the Tecres Interspace Hip and Knee devices are intended to be used in the same surgical procedure (two-stage revision procedure) in the same target patient population, and provide the same primary function of providing patients a temporary implant to allow for a natural range of motion and partial weight bearing.
TECHNOLOGICAL CHARACTERISTICS AND PERFORMANCE DATA 6
The Garventis Modular Spacer devices share many similar technological characteristics compared to the predicate Tecres Interspace Hip and Knee devices. The Garventis Modular Spacers and the predicate Tecres Interspace Hip and Knee share a similar size, shape and geometry, and are made from the same materials (PMMA). Each hip device also contains an inner stainless steel core for support. The Garventis Modular Spacers and the predicate Tecres Interspace Hip and Knee both incorporate gentamicin. Both devices share the same tissue contact and duration of contact. Both are provided preformed to the user, sterile, for single-use.
The design of the Hip Modular Spacer differs from the predicate device by its modular nature; it is provided as separate head and stem components, which have to be combined to achieve the final configuration of the implant. The design of the Knee Modular Spacer differs from the predicate device by its modular nature; it is provided as separate femoral and tibial components that must be coupled to achieve the final configuration of the implant. A tibial Insert is also available to be combined optionally with the Tibial component for increasing the final thickness.
3
