Patent number: 10238548Abstract: A water-resistant orthopedic undercast sleeve that includes a tubular sheet material formed of extruded filaments having water-resistant properties and a thickness sufficient to provide both cushioning and moisture transport in a single layer between a cast and a limb onto which the sleeve is applied. The water resistant properties are achieved by at least one process, including a water-resistant filler, finish or coating applied to the filaments during extrusion, applying a water resistant finish to the finish during extrusion, applying a water resistant finish to the filaments during a subsequent spinning process, or coating the filaments with a water-resistant finish in a separate process. Moisture egress channels are formed in the sheet material for transporting moisture away from the limb, longitudinally along the length of the sleeve, and out of the space between the sleeve and cast.Type: GrantFiled: July 14, 2006Date of Patent: March 26, 2019Assignee: BSN MEDICAL, INC.Inventors: John C. Evans, Shitij Chabba, Martin O'Hara

Patent number: 8708938Abstract: A low density fabric substrate for a medical bandaging product. The substrate has a plurality of longitudinally-extending voids formed in the fabric for permitting water penetration through the fabric thickness from one of the major faces to the other major faces. A reactive system is impregnated into or coated onto the substrate and remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to sufficient moisture to form a rigid, self supporting structure. A soft, flexible protective material covers at least one of the major faces of the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the material is in use.Type: GrantFiled: February 3, 2006Date of Patent: April 29, 2014Assignee: BSN Medical, Inc.Inventors: John C. Evans, Shitij Chabba, Martin O'Hara

Patent number: 8343082Abstract: A medical bandaging product, including a non-woven, fibrous, flexible medical material adapted for being applied and conformed to a body part to be supported, and a reactive system impregnated into or coated onto the medical material. The system remains stable when maintained in a non-activated condition in the absence of an activating agent, such as water, and hardens upon activation by exposure to the activating agent to form a rigid, self supporting structure. An enclosure is provided within which the medical material is maintained against exposure to the activating agent until use. The product may be in pre-cut shapes or in roll-form for cutting off a desired length for a given use.Type: GrantFiled: June 2, 2006Date of Patent: January 1, 2013Assignee: BSN Medical, Inc.Inventors: John C. Evans, Shitij Chabba, Martin O'Hara

Patent number: 8025631Abstract: An undercast liner for being applied to an anatomical shape of a patient and overlaid with a cast material. An elongate fabric has two opposing faces and an intermediate spacer area that both separates and interconnects the opposed faces. The liner is constructed at least in part of hydrophobic, water resistant monofilament yarn for providing enhanced water resistance, light weight, breathability and resistance to collapse and degradation due to moisture and bacteria during extended use to the liner. The liner has sufficient stretch in both a length-wise and width-wise direction to facilitate conforming the undercast liner around the anatomical shape without wrinkling during application.Type: GrantFiled: October 25, 2006Date of Patent: September 27, 2011Assignee: BSN Medical, Inc.Inventors: John C. Evans, Shitij Chabba

Patent number: 7972288Abstract: A medical bandaging product, including a sleeve formed of moisture-impervious material and sealable to prevent entry of moisture, and a medical material positioned in the sleeve and sealed therein against entry of moisture until use. The medical material is a substrate having two marginal areas of relatively lower modulus yarns and/or a more open knitted structure to provide reduced abrasion against the skin. A reactive system on the substrate remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to sufficient moisture to form a rigid, self supporting structure. A soft, flexible protective material covers at least one of the major faces of the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the material is in use.Type: GrantFiled: August 13, 2009Date of Patent: July 5, 2011Assignee: BSN Medical, Inc.Inventors: Shitij Chabba, Martin O'Hara, John C. Evans
