The COR® Precision Targeting System is a single patient use pre-sterile Osteochondral Autograft Transfer System featuring “No Impact Transfer” and “Low Impact Delivery” for protection of chondrocyte viability. It also features a first-of-kind perpendicularity device enabling perpendicular selection of the recipient and donor sites to maximize graft congruency. The disposable instrument kit allows the option of an Arthroscopic or Mini-Open technique.
The COR® Precision Targeting System is designed to surgically treat full thickness femoral articular cartilage lesions via autograft or allograft transplantation.
|Accuracy of Recipient and Donor Site Selection||The first-of-kind perpendicularity device enables reproducible and focused graft harvesting and drilling.|
|Drill bit with Spade Cutting Tip||Spade tip minimizes tip wandering. Fluted channels remove bone chips and reduce friction and heat that could cause cell damage.|
|Harvester Cutting Tooth||The cutting tooth underscores graft to allow for a complete and uniform plug harvest.|
|Protects Chondrocyte Viability 1,2. Gentle graft handling with “no-impact transfer” and “low-impact delivery”.||The unique Guide/Cutter allows harvesting and transfer. After harvesting the Guide/Cutter is inserted into the loader allowing transfer to the delivery tube by pushing on the cancellous surface. During delivery the plunger gently presses on the chondrocyte surface to deliver the graft to the recipient site.|
|8 and 12mm Dual sided Tamp||Allows fine tune graft placement after delivery of the graft to the recipient site.|
|Ease of Use||Intuitive handling and efficiency combined in a completely disposable system.|
|Pre-sterile Disposable Instrument system||Available in 6, 8, and 10mm diameters with perpendicularity rod.
Available in 4, 6, 8 and 10mm diameters without perpendicularity rod.
|Reusable COR™ System sizing Instruments||Allows evaluation of defect size prior to selecting a pre-sterile kit.|
