The MBAResorb Implant is indicated as an internal support to primary surgical interventions in the treatment of flat foot, providing structural support at minimum during the first three months of healing.

Device Description

The MBAResorb Implant consists of a soft-threaded implant designed to be inserted between the posterior and middle facets of the subtalar joint and corresponding instrumentation to facilitate insertion. The design differs from the predicate Subtalar MBA device only in that the material is reabsorbed into the body.

AI/ML Overview

This document describes a 510(k) premarket notification for a medical device called the MBAResorb Implant. It is not a study proving the device meets acceptance criteria. The document is an application to the FDA seeking clearance to market the device based on its substantial equivalence to previously cleared devices.

Therefore, the requested information regarding acceptance criteria, study details, sample sizes, ground truth establishment, expert involvement, and comparative effectiveness studies cannot be extracted from the provided text. These elements are typically found in clinical study reports or detailed performance data submissions, which are not present here.

Summary of what can be extracted related to the device and its intended use:

Device Name: MBAResorb Implant
Intended Use: "The MBAResorb Implant is indicated as an internal support to primary surgical interventions in the treatment of flat foot, providing structural support at minimum during the first three months of healing."
Material: Poly L-Lactide (PLLA), described as bioresorbable.
Predicate Device: KMI Subtalar MBA Orthopedic Foot Implant (K960692), cleared Jul 23, 1996.
Regulatory Clearance: The FDA letter (SEP - 6 2005) indicates that the device was deemed substantially equivalent to a legally marketed predicate device, allowing it to proceed to market. This is a regulatory clearance, not a performance study outcome.

4. Description of Device

The MBARsaro Implant consists of a soft-threaded implant designed to be inserted between the posterior and middle facets of the subtalar joint and corresponding instrumentation to facilitate insertion. The design differs from the predicate Subtalar MBA device only in that the material is reabsorbed into the body.

Materials: Poly L-Lactide (PLLA)

Shelf Life: This product will be labeled with a shelf life of 1 (one) year

Function: The system functions as a temporary, supplemental support to primary interventions in the treatment of flat foot.

1. Intended Use The MBAResor Implant is indicated as an internal support to primary surgical interventions in the treatment of flat foot, providing structural support at minimum during the first three months of healing'.
  Use of this implant is contraindicated for use in patients with the following conditions:
Active local infection / any evidence of infection �
Allergic reaction to foreign bodies .
Poor or insufficient bone stock ●
The presence of any clinica! or functional abnormalities that would . preclude the potential of achieving a good result for the patient
Other conditions that may place the patient at risk (physiologically) .

Comparison of technological characteristics of the device to predicate and legally 6. marketed devices:

There are no significant differences between the MBA Resorb Implant and other I horesrobable systems currently being marketed which would adversely affect the use of the product. The MBA Resorb Implant employs the same basic mechanical features as the predicate, legally marketed device specified in section I, but the material is reabsorbed by the body. The poly l-lactic acid material has been in use in a variety of other implant device applications for over 10 years.

Regulation Number and Section

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
