Patent number: 9771410Abstract: Foam-formed collagen strands and methods for forming strands involve depositing a dispersed solution of an isolated cleaned, de-fatted, enzymatically-treated (or non-enzyme treated) human-derived collagen product having a preserved amount of its natural constituents into grooves of a grooved plate, and processing the dispersed collagen product to provide a foam-formed collagen strand. Foam-formed collagen strands may be processed into threads having a matrix of reticulated pores to conduct biological materials in and through the strand, the collagen of the collagen strand comprising isolated, enzymatically-treated human derived collagen having a preserved amount of its natural collagen constituents.Type: GrantFiled: July 17, 2014Date of Patent: September 26, 2017Assignee: Warsaw Orthopedic, Inc.Inventors: Nels Lauritzen, Lawrence A. Shimp, Brent S. Mitchell

Publication number: 20150112380Abstract: A device worn by a patient for maintaining pressure at appropriate points on a patient's abdomen for treating gastroesophageal reflux and heartburn. The pressure is applied by the utilization of two protrusions. The position of both of the protrusions can be adjusted laterally relative to one another to ensure that pressure is applied to the correct position on the patient's body. Alternatively, the protrusions can be inflated to a particular level, allowing the protrusions to apply pressure to the body.Type: ApplicationFiled: October 21, 2013Publication date: April 23, 2015Inventors: BRIAN HELLER, NELS LAURITZEN, BARRY CONSTANTINE

Patent number: 8460691Abstract: Fenestrated wound repair scaffolds and methods for forming scaffolds involve dispersing human collagen having a preserved amount of native constituents in solution, depositing the human collagen dispersion in a tray, forming openings in the collagen dispersion and removing the liquid component to form a fenestrated wound repair scaffold. Fenestrated wound repair scaffolds include a network of openings passing linearly through the wound repair scaffold to form channels for cells to pass into so as to form a series of cell formations therein.Type: GrantFiled: April 23, 2010Date of Patent: June 11, 2013Assignee: Warsaw Orthopedic, Inc.Inventors: Nels Lauritzen, Lawrence A.

Publication number: 20060286146Abstract: The present invention provides methods and compositions involving resorbable hemostatic agents that have the essential absence of microfibrillar collagen. Resorbable hemostatic agents of the present invention comprise polyethylene glycol, which controls bleeding in tissue and does not delay or interfere with healing. The resorbable hemostatic agents of the present invention are biodegradable and biocompatible agents that effectively control bleeding in bone and other tissue without interfering with the subsequent healing of the tissue.Type: ApplicationFiled: June 15, 2006Publication date: December 21, 2006Applicant: Bonewax, LLCInventors: Barry Constantine, Nels Lauritzen
