BioSphere MIS Putty is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. BioSphere MIS Putty is indicated to be gently packed into bony voids or gaps of the skeletal system as a bone void filler in the extremities and pelvis, and as a bone graft extender in the posterolateral spine and intervertebral disc space. When used in intervertebral disc space, BioSphere MIS Putty is to be used as an autograft extender with an intervertebral body fusion device cleared by FDA for use with a bone void filler. These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.

BioSphere MIS Putty device is composed primarily of medical-grade 45S5 bioactive glass particles. The composition and formula of this material are unchanged and identical to that used in the BioSphere Reference Device (K173301). This submission expands the device's indication to include use in the intervertebral spine and incorporates minor changes to the applicator, delivery gun, and packaging.

BioSphere Flex is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. BioSphere Flex is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e., the extremities and pelvis). These defects may be surgically created osseous defects created from traumatic injury to the bone. BioSphere Flex must be hydrated with autogenous bone marrow prior to implantation. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.

BioSphere Flex is a sterile, single-use resorbable bone void filler that is composed of porous bioactive glass granules suspended in a carrier. BioSphere Flex utilizes 45S5 bioactive glass, which has been shown to be osteoconductive and bioactive. The carrier is composed of a porous scaffold of collagen and sodium hyaluronate. BioSphere Flex has the ability to absorb fluid such as bone marrow aspirate and becomes flexible following hydration. Following implantation into the target site, BioSphere Flex supports bone formation through the porosity of the implant and on the surface of the bioactive glass granules. As the materials resorb, the device is eventually replaced by host bone. BioSphere Flex is provided in a variety of forms.

BioSphere MIS Putty is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. BioSphere MIS Putty is indicated to be gently packed into bony voids or gaps of the skeletal system as a bone void filler in the extremities and pelvis, and as a bone graft extender in the posterolateral spine. These defects may be surgically created osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.

BioSphere MIS Putty ("BioSphere MIS") is an osteoconductive, bioactive bone void filler that, like its predicate device, is composed primarily of medical-grade 4555 bioactive glass particles. The composition and formula of this material is unchanged and is identical to that used in the BioSphere Putty predicate. The bioactive glass is mixed with an inert, moldable carrier using the exact same composition and formula as used in the predicate device. The only difference between the two devices is that BioSphere MIS Putty is supplied in a prefilled cannula with a delivery gun to aid with placement into certain types of bony voids that are otherwise difficult to reach. The manner in which the device is delivered to the target site does not play any role in the putty achieving its intended clinical purpose (i.e., supporting bone regeneration). Upon implantation of BioSphere MIS Putty into the target site, the carrier is absorbed by the site and the remaining bioactive glass particles provide an osteoconductive surface for bone formation. The bioactive glass particles are supplied in a spherical form, and the natural packing of the spheres creates 3-dimensional, interconnected porosity that allows for bone regeneration throughout the defect site. This is the same mechanism of action as with the predicate. In the posterolateral spine, BioSphere MIS Putty can be combined with autograff as a bone graft extender in the same manner as the predicate BioSphere Putty.

BioSphere Putty Bioactive Bone Graft (BioSphere Putty) is an osteoconductive, bioactive bone void filler that, like its predicate device, is composed of 45S5 bioactive glass particles. In BioSphere Putty, the bioactive glass is mixed with an inert, moldable carrier that aids in placement of the product into bony voids. Upon implantation, the carrier is absorbed by the site and the remaining bioactive glass particles provide an osteoconductive surface for bone formation. The bioactive glass particles are provided in a spherical form, and the natural packing of the spheres creates 3-dimensional, interconnected porosity that allows for bone regeneration throughout the defect site.
