Appl. No.:

15/745157

Inventors:

- Warsaw IN, US
Richard Wood Storrs - Berkeley CA, US
Michael D. Leach - Warsaw IN, US

Joel Carne - Holly MI, US

International Classification:

A61M 1/36
A61M 1/02
B01L 3/00

Abstract:

Disclosed is a device for separating a cellular component from a multicomponent fluid. The device can comprise a body, a first acoustic wave generator, and a second acoustic wave propagating component. The body can define a channel having a first surface and a second surface opposite the first surface. The channel can extend along a longitudinal axis from a first end to a second end. The first acoustic wave generator can be coupled to the first surface. The first acoustic wave generator can be configured to generate an acoustic wave having a wavelength. The second acoustic wave propagating component can be coupled to the second surface. The second surface can be spaced an integer fractional multiple of the wavelength from the first surface and each integer factional multiple equals a number of pressure nodes within the channel.

Abstract:

Oxygen diffusive wound dressings and methods of manufacturing and use are described herein. The wound dressing may generally provide a ready supply of oxygen to a wound being treated via one or more oxygen conduits which are designed to pass oxygen from ambient air or other oxygen reservoirs into proximity to the wound, and may also provide for exudate removal through transecting channels in fluid communication with both the wound surface and a hydrophilic absorbent material.

A61K 38/48

US Classification:

424 9464, 435214

Abstract:

Methods of generating thrombin and methods of applying a clotting tissue sealant to a site on a subject are provided. A blood component comprising platelets can be obtained from the subject. A hypotonic composition is contacted with a solid matrix to form a thrombin-containing liquid, where the hypotonic composition includes water, calcium, a blood component comprising platelets, and optionally a chelator. Calcium is present in the hypotonic composition in an amount greater than the amount of calcium that can be complexed by the chelator. Thrombin-containing liquid is then separated from the hypotonic composition and can be applied to the site on the subject to form a clot, for example, by combination with fibrinogen.
