Publication number: 20240115273Abstract: Methods and devices for harvesting cancellous bone are disclosed. The bone-harvesting device may include a cannula and a bone receptacle in communication with the cannula, wherein the cannula including a cutting surface positioned at or adjacent the distal end, the cutting surface being oriented at an angle, the angle being greater than 90 degrees relative to the longitudinal axis of the cannula, and the harvested bone is adapted to move from a position adjacent to the cutting surface through the cannula into the bone receptacle. The cutting surface of the cannula may be positioned at or adjacent the distal end, and positioned at least in part radially outward of the outer face of the cannula. The cannula may include a cutting surface positioned at or adjacent the distal end and an occluding geometry that partially occludes the distal end of the cannula adjacent the cutting surface. In addition, a suction port may be provided in communication with the bone receptacle.Type: ApplicationFiled: December 14, 2023Publication date: April 11, 2024Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: Maxim Budyansky, Neil Shah, Akhil Jay Khanna, Khaled M. Kebaish, Lee H. Riley, III

Patent number: 9277927Abstract: 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.Type: GrantFiled: February 10, 2012Date of Patent: March 8, 2016Assignee: The Johns Hopkins UniversityInventors: Akhil Jay Khanna, Peter Hwa-Ming Truskey, Maxim Budyansky, Shoval Dekel, Haim Gottfried, Neil Shah, Khaled M.

Patent number: 8343200Abstract: An orthopedic screw system. The screw system comprises an outer member and an inner screw. The outer member has a longitudinal inner channel that defines an interior sidewall and is provided with screw threads on its exterior and interior sidewalls. An inner screw has threads constructed and arranged to engage with those on the interior sidewall, such that the inner screw may be secured within the inner channel. When secured within the inner channel, at least a portion of the length of the inner screw extends beyond the outer member. Methods of installing the orthopedic screw system into osteoporotic or otherwise weakened bone are also disclosed.Type: GrantFiled: March 12, 2007Date of Patent: January 1, 2013Assignee: The Johns Hopkins UniversityInventors: A.
