Publication number: 20230405212Abstract: Disclosed embodiments may relate to dressings configured to provide negative-pressure wound therapy to a tissue site, while simultaneously shielding a portion of the tissue site from the negative pressure. For example, dressing assembly embodiments may comprise an outer dressing configured for applying negative-pressure wound therapy to a tissue site, and an underlying isolation patch configured for use under the outer dressing. The isolation patch may be configured to seal the portion of the tissue site so that it does not experience the negative pressure. Additionally disclosed are other apparatus, dressings, systems, and methods.Type: ApplicationFiled: September 1, 2023Publication date: December 21, 2023Inventors: Luke PERKINS, Christopher J. CARROLL, Shervin JAHANIAN, Jonathan G. REHBEIN

Publication number: 20230404813Abstract: Disclosed embodiments may relate to dressings, covers, and/or drapes configured to provide negative-pressure therapy to a tissue site, such as an incision. In some embodiments, the drape or cover may have an external support layer configured to render the cover or drape self-supporting. In some embodiments, the support layer may comprise a skeleton support structure having a plurality of coupled supports. In some embodiments, the skeleton support structure may be non-planar, for example having abase portion configured to support the cover and a projection portion configured to extend over the manifold of the dressing at a height above the base portion. In some embodiments, the skeleton support structure may be removably coupled to an outer surface of the cover or drape, allowing removal after the dressing has been applied to the tissue site.Type: ApplicationFiled: October 20, 2021Publication date: December 21, 2023Inventors: Jonathan G. REHBEIN, Luke PERKINS, Shervin JAHANIAN, Enrique L. SANDOVAL

Publication number: 20230000689Abstract: A dressing may include a manifold and a spacer fabric. The manifold may have a first side configured to face the tissue site, a second side opposite the first side, a thickness between the first side and the second side, a first portion, and a second portion. The spacer fabric may extend between the first portion and the second portion and may comprise a first layer coupled to the first portion, a second layer coupled to the second portion, and a spacer layer extending between the first layer and the second layer. The first layer and the second layer may be perpendicular to the first side of the manifold. The dressing may be configured to contract more in a first direction than in a second direction, wherein the first direction is perpendicular to an extension direction of the spacer fabric. Other dressings, apparatus, systems, and methods are disclosed.Type: ApplicationFiled: December 3, 2020Publication date: January 5, 2023Inventor: Shervin JAHANIAN

Publication number: 20220273496Abstract: An apparatus for applying negative pressure to a tissue site of a patient may include a tissue interface, a cover, an aperture in the cover, and a sealing member. The tissue interface may have an anatomical shape configured to cover the tissue site. The cover may be configured to cover the tissue interface. The aperture in the cover may be fluidly coupled to the tissue interface. The sealing member may be configured to seal the cover to the patient, wherein the cover and the sealing member are configured to cooperate to form a sealed chamber containing the tissue interface. The tissue interface may be coupled to a source of negative pressure, which can be delivered to the tissue interface for distribution to the tissue site. The source of negative pressure may be coupled to the cover of the apparatus.Type: ApplicationFiled: May 19, 2022Publication date: September 1, 2022Inventors: Jonathan G. REHBEIN, Richard Marvin KAZALA, JR., Larry Tab RANDOLPH, Tyler H. SIMMONS, Shervin JAHANIAN, Dane ANDERSON, Sara CINNAMON, Stefan FOULSTONE, Charles HARTZELL, Stephanie HENZE, Colton SANFORD

Publication number: 20210128340Abstract: A treatment system includes an dressing having a decompression layer and an occlusive layer that secures the dressing about a treatment site, and defines a treatment chamber within which the decompression layer is positioned. Operation of an air displacement device fluidly coupled to the chamber causes the decompression layer to compress away from the tissue site, resulting in a pulling force being imparted onto the treatment site. This decompression of the tissue site increases the perfusion of blood and other fluids, and advantageously may reduce swelling at the treatment site. To increase the degree of lifting of the treatment site, the decompression layer is advantageously constructed to exhibit a parallel plate effect during use of the treatment system. For example, the decompression layer is constructed having a center of stiffness located closer to an outwardly-facing surface of the decompression layer than a tissue-facing surface of the decompression layer.Type: ApplicationFiled: October 27, 2020Publication date: May 6, 2021Inventors: Shervin Jahanian, Richard Kazala, Larry Tab Randolph, Jonathan G.

Publication number: 20200038283Abstract: An apparatus for promoting circulation through a subcutaneous lymph vascular network may comprise a first manifold layer, a second manifold layer coupled to the first manifold layer, and a cover layer coupled to the second manifold layer. The first manifold may have a first stiffness, and the second manifold may have a second stiffness greater than the first stiffness. In some embodiments, the apparatus may additionally have a fluid interface configured to fluidly couple at least one of the first manifold layer and the second manifold layer to a fluid conductor through the cover layer. The fluid conductor may be coupled to or configured to be coupled to a source of negative pressure.Type: ApplicationFiled: July 30, 2019Publication date: February 6, 2020Inventors: Colin John HALL, Benjamin Andrew PRATT, Richard Marvin KAZALA, JR., Shervin JAHANIAN, Larry Tab RANDOLPH, Jonathan G.
