  • Publication number: 20200222195
    Abstract: Methods and apparatuses for performing an orthopedic procedure in the sacroiliac region are disclosed. In one form, an aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is inserted into the aperture. The undercutting system may include an insertion apparatus, a probe assembly, and a cutting assembly. The probe assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The probe assembly is manipulated within a joint between the ilium and the sacrum while the probe assembly is in the extended position. The cutting assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The cutting assembly is manipulated within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region.

  • Publication number: 20190262050
    Abstract: A tissue collection and processing system for collecting bone fragments and tissue aspirated from a bone. The tissue collection and processing system includes a collection vessel, a collection vessel cap, a processing cover, a first tubing and a fluid withdrawal mechanism. The collection vessel has an opening formed therein to receive bone fragments and tissue aspirated from the bone. The collection vessel cap is capable of engaging the collection vessel to substantially seal the opening. The collection vessel cap or the collection vessel has a first port. The processing cover has an upper surface and a lower surface. The processing cover has a connection port and a bore. The connection port is proximate the upper surface. The bore is fluidly connected to the connection port and extends toward the lower surface. The processing cover has a density that is less than a density of fluid in the aspirated bone fragments and tissue.

  • Publication number: 20180353206
    Abstract: A method of treating soft tissue conditions. A harvesting device is provided. The harvesting device is operably connected to a tissue processing device using tubing. An aperture is formed in a bone. The bone has an interior. The harvesting device is inserted through the aperture in the bone and into the interior of the bone. The harvesting device is manipulated to dissociate connective tissue progenitor cells in the interior of the bone. Tissue is aspirated from the interior of the bone. The connective tissue progenitor cells are separated from the aspirated tissue. The separated connective tissue progenitor cells are injected in a region of a body that is experiencing a soft tissue condition to treat the soft tissue condition.

  • Patent number: 9861375
    Abstract: An undercutting system for preparing a region between an ilium and a sacrum for sacroiliac fusion. The undercutting system includes an insertion apparatus and a cutting assembly. The cutting assembly is operably mounted with respect to the insertion apparatus. The cutting assembly has a distal end and a proximal end. The cutting assembly includes a plurality of cutting elements and a cutting element attachment mechanism. The cutting element attachment mechanism engages the cutting elements to operably mount the cutting elements with respect to the insertion apparatus. The cutting element attachment mechanism permits the cutting elements to pivot with respect to each other.
