Publication number: 20160074232Abstract: A cover layer for a vacuum wound therapy dressing includes a backing layer formed from a flexible polymeric membrane and an adhesive layer for affixing the backing layer over a wound bed to provide a substantially fluid-tight seal around a perimeter of the wound bed. The cover layer is reinforced with a reinforcement layer extending to a peripheral region of the backing layer to distribute forces associated with evacuating a reservoir, as defined by or within the cover, to stimulate healing of the wound bed.Type: ApplicationFiled: November 20, 2015Publication date: March 17, 2016Inventors: Ronald F. Vitaris, Bethany A. Vitaris

Publication number: 20160045374Abstract: A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peal-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.Type: ApplicationFiled: October 29, 2015Publication date: February 18, 2016Inventor: Ronald F. Vitaris

Publication number: 20150335799Abstract: A composite wound dressing and delivery apparatus includes a substantially transparent dressing layer having a lower surface that is coated with a pressure sensitive for applying the dressing layer over a wound to define a reservoir in which a negative pressure may be maintained. A substantially transparent backing layer adhered to the lower surface of the dressing layer in a releasable manner, and a vacuum port is centrally located on the dressing layer. The vacuum port is adapted to provide fluid communication between a vacuum source and the reservoir through the dressing layer. A targeting grid associated with either the dressing layer or the backing layer includes regularly spaced reference marks along at least two axes extending from the vacuum port.Type: ApplicationFiled: April 24, 2015Publication date: November 26, 2015Inventors: Ronald F.

Publication number: 20130172833Abstract: A wound therapy apparatus for enhancing healing of a wound includes a wound dressing configured for placement over the wound to define a reservoir over the wound in which a wound contact fluid may be maintained by forming a substantially fluid-tight seal around the wound. An elastic bladder member defined by or within the wound dressing is expandable to exert a pressure on the wound contact fluid within the reservoir. A fluid system is in fluid communication with the reservoir for selectively delivering the wound contact fluid to the reservoir, and a pressure system is in fluid communication with the bladder member for delivering a compressed liquid or gas to the bladder member to effect expansion in the bladder member.Type: ApplicationFiled: July 18, 2012Publication date: July 4, 2013Applicant: TYCO HEALTHCARE GROUP LPInventor: Ronald F.

Publication number: 20120083723Abstract: A wound dressing for managing wound fluids includes a porous contact layer for positioning adjacent a wound. An internal open window extends through the contact layer exposing a distal side of an absorbent member. The absorbent member is disposed in a superimposed relation to the window of the contact layer and is dimensioned to extend laterally beyond the window such that a portion of the absorbent member overlaps and is secured to the contact layer. A drape layer is disposed on a proximal side of the absorbent member, and is adhesively coated to fasten the drape layer to the absorbent member. A cover layer disposed over the drape layer defines an internal open window such that the open window is adjacent the absorbent member. A distal side of the cover layer is adhesively coated to secure the cover layer to the contact layer.Type: ApplicationFiled: September 30, 2010Publication date: April 5, 2012Applicant: TYCO HEALTHCARE GROUP LPInventors: Ronald F.
