PURactiveOrb™
Bioactive glass, finally in a form that behaves in the hand. PURactiveOrb packs 45S5 bioactive glass into engineered spheres of two sizes, about 80% glass by weight, in a moldable, non-hardening phospholipid putty. Shape it, place it, and let the carrier get out of the way.
Two sphere sizes90–180 µm and 355–500 µm, blended in a fixed ratio for dense packing
~80% glass by weightAbout 1.5 g of 45S5 bioactive glass in every cc
Carrier that steps asideNatural phospholipid, resorbed by local tissue, leaving glass against host bone

PURbonedough™
The allograft surgeons reach for by feel. PURbonedough is 100% demineralized cortical bone in a dough that holds together, holds its shape and packs exactly where you put it, with every lot verified for osteoinductive potential before it ships.
100% corticalDemineralized cortical bone matrix, no filler
Dough handlingPacks, holds its shape and stays put
Verified every lotOsteoinductive potential confirmed lot by lot, not sampled
Sterile, still biologicProcessed to deliver sterility without degrading activity
The PUR standard
Discipline you can feel in the graft.
Accreditation and sterility assurance are the entry ticket in this market. What separates a graft is the judgment behind it.
13years in orthobiologics
20+years of surgical experience per founder
1000sof surgeries supported
- Donor selection, earned over twenty years
Donor source quality and selection judgment built case by case, not read from a spec sheet.
- Osteoinductivity verified on every lot
Allograft DBM lots are tested for osteoinductive potential before release, not sampled.
- Sterility that preserves biology
Processing designed to deliver a sterile graft without degrading the activity surgeons are relying on.
- Redundant donor sourcing
Multiple qualified tissue sources so supply does not dictate the surgeon's choice of graft.

PURactiveOrb · MIS delivery
Your graft. Your approach.
PURactiveOrb is available with a minimally invasive delivery option: a trigger-fed instrument and cannula that place putty through a small access corridor.
Company
Focused on biologics. Built around surgeons.
PUR Biologics is a commercial-stage orthobiologics company based in Irvine, California. For thirteen years we have brought allograft, synthetic graft and marrow-collection products to spine and orthopedic surgeons through a focused portfolio and direct relationships with the people who use it.
We work with surgeons, hospitals and surgery centers, and distribution partners across the United States.

Synthetic bone graft
PURactiveOrb™
The bioactive glass putty surgeons can shape. 45S5 glass in engineered spheres, about 80% glass by weight, in a resorbable phospholipid carrier: moldable, non-hardening, resists irrigation, and ready through a 9 mm cannula.

Material & handling
Engineered down to the sphere.
A material with history. A form without compromise.
45S5 bioactive glass is among the most studied synthetic graft materials in orthopedics. Conventional putties use it as crushed, irregular particles. PURactiveOrb uses spheres: two engineered diameters, 90–180 µm and 355–500 µm, blended in a fixed ratio so the particles pack densely and present a consistent surface to surrounding bone.
The result is a putty that is about 80% bioactive glass by weight, roughly 1.5 grams of glass in every cc, bound by a natural phospholipid carrier that gives it its feel. After placement the carrier is resorbed and the glass remains in direct contact with host bone.
In a preclinical rabbit defect model, new bone formed directly on the sphere surfaces and in the spaces between them, with bone present throughout the implant area at six weeks.1
Supplied in an open-bore syringe sealed within two foil pouches, in 2.5, 5 and 10 cc volumes. No hydration step.
- MoldableShape it in your fingers, contour it to the defect, place it.
- Non-hardeningStays workable and does not set in situ. Not intended to provide structural support.

Product information
Indications & safety.
Intended use
PURactiveOrb Putty is indicated for bony voids or gaps that are not intrinsic to the stability of the bony structure. It is indicated as a bone void filler in the extremities and pelvis, and as a bone graft extender in the posterolateral spine.
For posterolateral fusion, PURactiveOrb Putty must be mixed with autograft in a 1:1 ratio.
This summary does not replace the complete instructions for use, including contraindications, warnings, precautions and directions.
Handling
Do not add fluid directly to the putty, including blood or saline. This may negatively affect handling and cohesiveness. Refer to the current IFU for preparation and use.
Structural support and single use
The product does not possess sufficient mechanical strength to solely support defect reduction. Appropriate stabilization is required. The product is for single-patient, single use only.

Development platform
A different architecture for graft extension.
A synthetic graft platform of porous HA/TCP spheres contained in a mesh format, developed for posterolateral spine graft extension. The platform is 510(k)-cleared; manufacturing transfer and shelf-life work are the next milestones on the path to commercial release.
This platform is distinct from PURactiveOrb Putty, our bioactive glass product.

Intellectual property
Multiple international patents and applications.
PUR's intellectual-property portfolio spans extracellular matrix manufacturing and regenerative cell-activation technologies, with patent work extending into bone and cartilage programs. These technologies form the foundation for a research pipeline that reaches beyond today's commercial catalog.
Research directions
Three paths. A regenerative focus.
