Patent number: 11883078Abstract: An implant for fusing a joint between first and second bone portions. The implant includes a screw member, and a washer polyaxially rotatable relative to the screw member. The screw member includes a head, a lag zone, and a threaded engagement zone. The implant includes a fusion zone for joint compression, extending from the washer to the proximal end of the engagement zone. Fenestrations may be present in the fusion zone. The length of the fusion zone ranges from about 10 mm to about 37 mm. Different surface finishes including roughened and non-roughened may be applied selectively to selected portions of the implant. In an embodiment, the joint is a sacro-iliac joint, and upon implantation the implant extends from the exterior of the ilium, across the joint and into the sacral vertebral body. Instrumentation and methods for preparing the joint and implanting the implant are disclosed.Type: GrantFiled: September 13, 2021Date of Patent: January 30, 2024Assignees: IMDS LLC, Mayo Foundation for Medical Education and ResearchInventors: Brian Scott Schumacher, Nicholas Slater, William W.

Patent number: 11357557Abstract: A sacroiliac joint fusion screw and associated delivery tools and method. Embodiments of the sacroiliac joint fusion screw comprise a shaft having proximal and distal end portions and a head on the proximal end of the shaft. A threaded portion on a distal portion of the shaft is configured to engage a sacrum. A glide zone portion on the shaft between the threaded portion and the proximal end portion is configured to extend through an ilium. The screw can provide stability and compression to the joint.Type: GrantFiled: July 9, 2018Date of Patent: June 14, 2022Assignee: Mayo Foundation for Medical Education and ResearchInventor: William W.

Patent number: 10751071Abstract: Systems and methods for joint preparation and fusion are disclosed. The system includes a cutting device having a handle, and rigid blade member. The blade member may include cutting edges on first and second sides, and may be curved in one or more planes. The blade member may be deployed to project outside of an outer tube, and the cutting device may be rotated to create a circular cavity. In a method of use, a cannula provides access to a procedure site such as a joint. A pathway to the joint is created, and the cutting device is inserted and deployed to undercut a cavity in the joint. A fusion device may be implanted across the joint to provide compression and fuse the joint. The system may also include instrumentation for creating access to a joint, bone graft insertion and implant insertion.Type: GrantFiled: April 25, 2016Date of Patent: August 25, 2020Assignee: IMDS LLCInventors: Björn N.
