No
The device description and intended use clearly describe a mechanical bone plug made of acrylic, with no mention of software, algorithms, or any AI/ML related terms.
No.
A therapeutic device is typically characterized by its direct treatment or therapy of a disease or condition. This device's primary function is to restrict bone cement migration during surgical procedures, which is a supportive role in a surgical process rather than a direct therapeutic intervention.
No
The device is described as an "Intramedullary Bone Plug" intended to restrict bone cement migration and permit cement pressurization during hip arthroplasty, which is a therapeutic rather than diagnostic function.
No
The device description explicitly states it is a "molded acrylic device" and describes its physical characteristics and function as a physical implant.
No, the Exeter II Intramedullary Bone Plug is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. This includes things like blood, urine, tissue, etc., to provide information about a physiological state, health, disease, or congenital abnormality.
- The Exeter II Intramedullary Bone Plug is a surgical implant. Its intended use is to be physically placed within the femoral canal during a surgical procedure (total hip arthroplasty) to restrict bone cement migration. It does not analyze or test any biological specimens.
The description clearly indicates it's a molded acrylic device designed for physical placement within the body, not for in vitro testing.

Device Description
The Exeter Intramedullary Bone Plug is a molded acrylic device that is designed to be placed in the femoral canal prior to the insertion of a femoral stem. The bone plug restricts the migration of bone cement down the femoral canal and permits cement pressurization within the canal. The Exeter Bone Plug described in this submission is the same design as the currently marketed device. The Bone Plug is a cone shaped device available in a range of diameters to accomodate various anatomical requirements. The distal portion of the plug is designed with circumferential ridges that create an interference fit between the plug and the femoral canal. Slots are cut into the ridge portion of the bone plug to allow the plug to compress slightly during insertion down the canal. The body of the plug contains a threaded portion for use with an insertion instrument.

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
