The summary describes a bone graft substitute material and its physical properties and performance in animal studies. There is no mention of software, algorithms, image processing, or any other technology that would typically incorporate AI/ML.
Yes
The device is described as a "bone graft substitute" that is intended for use in "open bone voids/gaps" and "resorbs and is replaced with bone during the healing process," indicating a direct therapeutic action in promoting bone regeneration and healing.
No
This device is described as a bone graft substitute intended to fill bone voids and augment hardware during surgery, which is a therapeutic function, not diagnostic.
No
The device description clearly states it is a physical bone graft substitute consisting of a powder and liquid component that form a paste, indicating it is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a bone graft substitute to be injected or packed into bone voids/gaps within the skeletal system. This is a therapeutic use, not a diagnostic one.
- Device Description: The description details the composition and function of the material as a bone graft substitute that hardens in situ. This aligns with a therapeutic device, not a diagnostic one that analyzes samples from the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.
Therefore, the PRO-DENSE™ device is a therapeutic medical device, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
PRO-DENSE™ resultant paste is intended for use as a bone graft substitute to be injected or digitally packed into open bone voids/gaps that are not intrinsic to the stability of bony structure of the skeletal system (i.e., the extremities, spine, and pelvis) to cure in-situ. These open bone voids may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The paste provides a bone graft substitute that resorbs and is replaced with bone during the healing process.
The PRO-DENSE™ paste cured in situ provides an open void/gap filler that can augment provisional hardware (e.g. K-Wires) to help support bone fragments during the surgical procedure. The cured paste acts only as a temporary support media and is not intended to provide structural support during the healing process.

Device Description
The PRO-DENSE™ Bone Graft Substitute material is indicated as a bone graft substitute to be injected, digitally packed into open bone voids/gaps that are not intrinsic to the stability of bony structure of the skeletal system to cure in-situ.
PRO-DENSE™ consists of a calcium sulfate - calcium phosphate composite bone graft substitute consisting of a powder component and an aqueous mixing solution. When the two components are mixed, according to directions, an injectable paste is formed which subsequently hardens via hydration reactions. The paste can be injected and cured in situ or gently packed into bony defects.

- Claim 3: "The accelerated rate of healing of the PRO-DENSE treated defects compared to those treated with autograft is principally evident by the higher density bone (i.e., 170% average increase in area fraction of new bone compared to autograft at 13 weeks) and superior average mechanical properties at 13 weeks: Faster than autograft." Substantiated by 170% average increase in new bone volume, and 645% increase in ultimate compressive strength and 600% increase in elastic modulus.
- Claim 4: "Newly regenerated bone from the PRO-DENSE™ injectable treated defects remodeled to normal host bone, demonstrated by normal trabecular architecture histologically, and no significant difference in mechanical properties (compressive strength and modulus of elasticity) at the 26 week timepoint: Remodels to normal bone." Substantiated by no statistically significant difference in area fraction of new bone to normal bone at 26 weeks, and no statistically significant difference in ultimate compressive strength and modulus of elasticity to normal bone samples at 26 weeks.
- Claim 5: "The compressive modulus of the newly regenerated bone from the PRO-DENSE™ injectable treated defects at both 13 and 26 weeks falls within the published range for normal human cancellous bone: No modulus mismatch." Substantiated by comparison of measured compressive modulus values to published range for normal human cancellous bone.
All claims are based on a critically sized canine proximal humerus defect model.

NON-CLINICAL PERFORMANCE/MARKETING CLAIMS
- *All claims are based on a critically sized canine proximal humerus defect model. It is unknown how results from the canine model compare with clinical results in humans.
- · Claim 1: The newly regenerated bone in the PRO-DENSE™ injectable treated defects exhibited a 645% average increase in compressive strength at 13 weeks versus defects treated with autograft: Stronger than autograft.*
Substantiation: Ultimate compressive strength in PRO-DENSE™ injectable increased 645% compared to the autograft group.
-
· Claim 2: Histomorphometry reveals that the amount of newly regenerated bone of the PRO-DENSE™ injectable treated defects at 13 weeks demonstrated a statistically significant 170% average increase in new bone formation versus defects treated with autograft. PRO-DENSE™ injectable new bone area fraction is on average 170% denser than autograft at 13 weeks: Denser than autograft. *
Substantiation: Results showed that PRO-DENSE™ injectable demonstrated a 170% average increase in new bone volume over autograft treatment. -
· Claim 3: The accelerated rate of healing of the PRO-DENSE treated defects compared to those treated with autograft is principally evident by the higher density bone (i.e., 170% average increase in area fraction of new bone compared to autograft at 13 weeks) and superior average mechanical properties at 13 weeks: Faster than autograft. *
Substantiation: Results showed that PRO-DENSE™ injectable demonstrated a, statistically significant, 170% average in new bone volume over autograft treatment. Ultimate compressive strength and elastic modulus in PRO-DENSE™ injectable increased 645% and 600% respectively, compared to the autograft group. -
· Claim 4: Newly regenerated bone from the PRO-DENSE™ injectable treated defects remodeled to normal host bone, demonstrated by normal trabecular architecture histologically, and no significant difference in mechanical properties (compressive strength and modulus of elasticity) at the 26 week timepoint: Remodels to normal bone. *
Substantiation: Area fraction of new bone results of PRO-DENSE™ injectable showed no statistically significant difference to normal bone area fraction, indicating that the PRO-DENSE™ injectable has substantially remodeled toward the normal state of trabecular bone by 26 weeks. Additionally, ultimate compressive strength and modulus of elasticity of PRO-DENSE™ injectable at 26 weeks showed no statistically significant difference to normal bone samples. -
· Claim 5: The compressive modulus of the newly regenerated bone from the PRO-DENSE™ injectable treated defects at both 13 and 26 weeks falls within the published range for normal human cancellous bone: No modulus mismatch. *
Substantiation: An examination of published values of compressive modulus for human cancellous bone shows that even the highest value measured for PRO-DENSE™ injectable treated defects is still well within the range of normal cancellous bone.
