Patent number: 11931087Abstract: 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 piston, 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 piston has an upper surface and a lower surface. The processing piston 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.

Patent number: 9045735Abstract: Methods for enriching, detecting, or using adult stem cells through the use of recognition ligands that specifically bind to ECM components retained to the surfaces of adult stem cells are described. An ECM component such as hyaluronan that is retained to the surfaces of adult stem cells when removed from animal tissues can be used to detect a diverse population of adult stem cells based on the nature of the ECM niche region in which the adult stem cells normally reside. For example, a separation method such as magnetic separation can be used to detect and isolate or enrich adult stem cells based on a recognition ligand that is specific for an ECM component that is retained to the surfaces of adult stem cells to a greater degree than to other cells in the population.Type: GrantFiled: April 3, 2008Date of Patent: June 2, 2015Assignee: THE CLEVELAND CLINIC FOUNDATIONInventors: George Muschler, Tonya Caralla, Vincent Hascall, Ronald Midura

Publication number: 20070055282Abstract: A minimally invasive apparatus and method for harvesting bone marrow cells, blood, and bone fragments includes a rigid cannula having a proximal end and a distal end with an opening. The distal end includes a cutting tip that is movable axially and radially to cut and disrupt bone tissue while preserving necessary viability among harvested marrow cells. The cannula further includes an inner surface defining an internal passage that extends from the opening toward the proximal end. Suction is applied to the passage to draw disrupted bone marrow cells, blood, and bone fragments into the internal passage for collection. The apparatus may include a rotatable shaft disposed co-axially within the internal passage. The shaft has a distal end with a cutting bit for further cutting and disrupting of bone tissue, and a lumen for supplying bone cement to the cutting bit to promote bone growth and healing within the bone.Type: ApplicationFiled: November 9, 2006Publication date: March 8, 2007Inventor: George Muschler
