AI Technical Summary

Benefits of technology

The device enables safe, cost-effective, and efficient bone graft harvesting with reduced morbidity, enhancing fusion rates and reducing the reliance on expensive bone substitutes like BMPs and allografts, thereby maintaining high standards of care while lowering healthcare costs.

Problems solved by technology

In the current U.S. healthcare market, cost constraints are becoming a central and ever-growing issue.
A failed fusion can mean an additional surgical procedure, with potentially life threatening risks to the patient, as well as huge additional costs to the healthcare system.
Nevertheless, there are still risks and substantial costs associated with harvesting bone grafts using currently available techniques and methods.

Abstract

A minimally-invasive bone graft harvesting device, kit, and method are provided. The device includes a hollow cutting element and an extraction element. The hollow cutting element may define a longitudinal axis and includes a distal end, a proximal end adapted to be coupled to a powered or manual-operated rotary tool, and an inner lumen extending longitudinally between the distal and proximal ends. The hollow cutting element may also include one or more blades protruding from an outer surface of the cutting element. Each blade may be arranged adjacent to an opening extending between the outer surface and the inner lumen to allow cancellous bone material cut by each blade during use to pass through the opening into the inner lumen. The extraction element may be removably received within the inner lumen of the hollow cutting element to allow withdrawal of the bone material in the inner lumen.

Description

CROSS-REFERENCE OF RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Application No. 61 / 441,955 filed Feb. 11, 2011. This application claims priority to U.S. Provisional Application No. 61 / 471,273, filed Apr. 4, 2011. The entire contents of each of the foregoing applications are hereby incorporated by reference.BACKGROUND[0002]1. Field of Invention[0003]The field of the currently claimed embodiments of this invention generally relates to devices and methods for harvesting bone grafts.[0004]2. Discussion of Related Art[0005]In the current U.S. healthcare market, cost constraints are becoming a central and ever-growing issue. In this landscape, hospitals and surgeons are being pressured to cut the costs of various procedures while still maintaining good clinical outcomes. One area which has potential to concurrently reduce costs and increase care is in the area of bone graft harvesting for use in complex surgical procedures such as, for example, spinal fusi...
