Patent number: 10603665Abstract: A system and associated method for concentrating and separating components of different densities from fluid containing cells using a centrifuge includes a container defining a cavity for receiving the fluid. The container has a top, a sidewall extending from the top, and a bottom disposed opposite the top and in sealing engagement with the sidewall. An insert is slidably disposed in the cavity of the container and defines a lumen through the insert. The lumen, which includes a hole and a funnel-shaped upper portion in fluid communication with the hole, forms an open fluid path between opposite ends of the insert. The insert has a density such that upon centrifugation a selected component of the fluid resides within the lumen. A container port is disposed in the top of the container to transfer the fluid into the container and to withdraw a fluid component other than the selected component from the container.Type: GrantFiled: January 29, 2014Date of Patent: March 31, 2020Assignee: EndoCellutions, Inc.Inventors: Andy H. Levine, John C. Meade, Neil Tischler, Jeffrey R. Chabot, Andrew McGillicuddy, Neil F. Duffy, Jr.

Patent number: 10568661Abstract: A bone marrow access device includes a cannula and a sharp stylet removably positioned in the cannula. The cannula defines a distal opening at a distal tip and a side aperture in a side of the cannula, proximally from the distal opening. The stylet has a sharp distal tip and extends beyond the distal opening. A plug is receivable in the cannula distal to the side aperture to seal the distal opening when the stylet is removed. A method of accessing bone includes inserting the cannula and sharp stylet positioned in the cannula into bone; removing the sharp stylet from the cannula; pushing a plug through the cannula and distal to the side aperture to seal the distal opening of the cannula; and accessing the bone through the side aperture. Accessing the bone can include aspirating bone marrow, injecting a substance, or inserting an instrument into the bone.Type: GrantFiled: September 29, 2017Date of Patent: February 25, 2020Assignee: EndoCellutions, Inc.Inventor: Andrew McGillicuddy

Patent number: 10556046Abstract: A bone marrow aspiration device and associated method includes an introducer needle assembly and an aspiration needle assembly. The introducer needle assembly includes an introducer cannula having proximal and distal ends, each end including an opening, and a screw assembly coupled to the introducer handle. The screw assembly includes a threaded tube and a lead screw receivable in the threaded tube. An outer cover is disposed around and in sealing engagement with the threaded tube and the lead screw. The aspiration needle assembly is receivable in the introducer cannula and includes an aspiration cannula forming a channel for aspirating bone marrow and including a flexible portion that extends from a distal end along a length of the aspiration cannula. A length of the aspiration cannula that extends beyond the distal end of the introducer cannula is adjustable by advancing the lead screw into or reversing the lead screw out of the threaded tube.Type: GrantFiled: January 15, 2015Date of Patent: February 11, 2020Assignee: EndoCellutions, Inc.Inventors: Andrew McGillicuddy, Andy H.

Patent number: 10231716Abstract: A bone marrow aspiration device and associated method includes an introducer needle and an aspiration needle. The introducer needle includes an introducer cannula and a removable introducer stylet that includes a sharp tip to penetrate bone. The aspiration needle includes an optionally flexible aspiration cannula and a blunt stylet. The aspiration needle is receivable in the introducer cannula when the introducer stylet is removed from the introducer needle. The aspiration cannula forms a channel for aspirating bone marrow when the stylet is removed. The aspiration device also includes a locking mechanism to lock the aspiration cannula to the introducer cannula when the aspiration cannula is received in the introducer cannula, whereby the aspiration cannula can be advanced distally relative to the introducer cannula in a controlled manner, and whereby pulling the aspiration cannula proximally causes the introducer cannula to move proximally with the aspiration cannula.Type: GrantFiled: October 29, 2013Date of Patent: March 19, 2019Assignee: EndoCellutions, Inc.Inventors: Andrew McGillicuddy, Andy H. Levine, Neil F. Duffy, Jr.

Patent number: 10005081Abstract: A system for separating components defining a cavity for receiving the fluid. The system further includes a rigid insert slidably disposed in the cavity, the insert including a funnel-shaped upper portion and a hole therethrough. The insert has a density such that upon centrifugation a selected component of the fluid resides within the upper portion of the insert. A bone marrow aspiration device includes an introducer needle assembly and an aspiration needle assembly. The introducer needle assembly includes an introducer cannula and a removable trocar. The aspiration needle assembly includes a flexible aspiration cannula and a flexible stylet. The length of the aspiration cannula is substantially greater than the length of the introducer cannula. The aspiration needle assembly is receivable in the introducer cannula when the trocar is removed from the introducer needle assembly. The aspiration cannula forms a channel for aspirating bone marrow when the stylet is removed.Type: GrantFiled: February 11, 2016Date of Patent: June 26, 2018Assignee: EndoCellutions, Inc.Inventors: Neil Francis Duffy, Jeffrey R.

Patent number: 9763877Abstract: The anatomic and functional arrangement of the gastrointestinal tract suggests an important function of this organ is its ability to regulate the trafficking of metabolites as well as control the equilibrium between tolerance and immunity through gut-associated lymphoid tissue, the neuroendocrine network, and the intestinal epithelial barrier. Combining nucleated cells from various tissues and introducing them directly into the small intestine will have a positive effect on diabetes.Type: GrantFiled: August 10, 2015Date of Patent: September 19, 2017Assignee: EndoCellutions, Inc.Inventors: Neil F. Duffy, Jr., Andrew McGillicuddy

Patent number: 8241592Abstract: Disclosed herein are apparatus and methods for isolating a fraction of interest from a physiological fluid sample. A sample holder for isolating a fraction of interest from a physiological fluid sample includes a flexible compartment and a rigid exoskeleton that supports the flexible compartment. The flexible compartment may have at least one reservoir with a height to volume ratio of about 0.1 cm/mL to about 5 cm/mL. An automated device for extracting a fraction of interest from the sample includes a sample holder with a flexible compartment supported by a rigid exoskeleton, a support for the sample holder connected to one or more fluid extraction devices, and a motor for moving the extraction device relative to the sample holder. The automated device may include an optical sensor and may include a clamp for clamping the flexible compartment.Type: GrantFiled: September 29, 2011Date of Patent: August 14, 2012Assignee: Endocellutions, Inc.Inventors: Neil F.
