Patent number: 9597444Abstract: Systems and methods for performing a red blood cell exchange procedure are disclosed. In one aspect, the flow rates of a replacement fluid (e.g., red blood cells from a healthy donor) and plasma being flowed to a blood source are calculated based on certain parameters of the procedure that are known, including the flow rate of blood being drawn from the source and the volume of replacement fluid to be used during the procedure. The replacement fluid flow rate and the plasma flow rate are calculated in a way that allows for simultaneous depletion of the supply of replacement fluid and achievement of another prescribed process parameter. The other prescribed process parameter depends on the nature of the procedure, namely whether the fluid volume and hematocrit of the source are to change by the end of the procedure or remain the same.Type: GrantFiled: May 12, 2014Date of Patent: March 21, 2017Assignee: Fenwal, Inc.Inventors: Zahra R.

Patent number: 9597449Abstract: Embodiments of the invention provide infusion systems for the intravenous or other delivery of drugs and other therapeutic agents to a patient including a human or mammal. The therapeutic agents may be dissolved in solution or comprise the solution itself. Embodiments of the systems can utilize a chemical reaction to predictably drive a flow of drug(s) through a catheter or other flow path and into the patient. More specifically, the reaction may include an acid-base reaction or any other reaction that produces a gaseous substance. The gas is produced and contained in an expandable drive balloon when the acid-base reactants are combined with a liquid. As the gas is produced, the drive balloon expands to exert pressure on a separately-contained drug reservoir which, in turn, pushes drug(s) from the reservoir into the flow path where the drug is ultimately delivered to the patient in a controlled and predetermined manner.Type: GrantFiled: March 13, 2014Date of Patent: March 21, 2017Assignee: InCube Labs, LLCInventor: Mir Imran

Patent number: 9597483Abstract: Tear-away and non-tear-away sheath introducers for catheters, methods for making such introducers, and methods for using such introducers are described. The sheath introducers contain movable valves that are encapsulated in a movable housing unlike conventional valves that are stationary. The movable housing allows the valve to move along the axis of the introducer. As the movable valve and housing travel along the axis, a portion of the hub protrudes past the valve and is exposed. The protruding portion of the hub contains a friction-free pathway for the catheter into the sheath introducer. The introducers can therefore be used with any catheter, regardless of the size or material, because of the reduced or eliminated frictional force between the catheter and introducer.Type: GrantFiled: November 29, 2005Date of Patent: March 21, 2017Assignee: C. R. Bard, Inc.Inventors: Eric M. King, Ronald Wortley

Patent number: 9597487Abstract: The present invention discloses multiple approaches to preventing the capsule walls and other material from interfering with the performance of an electronic device once the device is activated by surrounding fluid. In accordance with the teachings of the present invention, a miniature ingestible device (MID) may be created using excipients and films. The MID, in accordance with various aspects of the present invention, will have a coating or laminating surrounding an electronic device and separating and isolating the device from the pharmaceutical product or drug within the capsule once the capsule is ingested as well as from the capsule itself as the capsule walls begin to collapse during the disintegration process.Type: GrantFiled: April 7, 2011Date of Patent: March 21, 2017Assignee: Proteus Digital Health, Inc.Inventors: Timothy Robertson, Hooman Hafezi, Raymond Schmidt

Patent number: 9597488Abstract: Apparatus for applying rub-on and roll-on topical products such as medications, pain relievers, deodorants, cosmetics, and any other product having a built in applicator to the user's skin surface in hard-to-reach locations without undo strain or injury. The apparatus comprises a chamber assembly and an elongated handle. The chamber assembly comprises a rounded hollow T-shaped body having a protrusion on one side with a threaded inner surface to receive the elongated handle. The elongated handle has a threaded end that is deeper than the protrusion of the chamber assembly. When a container is placed into the chamber assembly from the top section and the elongated handle is hand-tightened, the threaded end comes in contact with the container and holds it securely in place, allowing the user to apply rub-on and roll-on medications and other products to hard-to-reach places of the body without undo strain or injury.Type: GrantFiled: February 10, 2016Date of Patent: March 21, 2017Inventor: Paul Jones

Patent number: 9597489Abstract: A wound dressing has a micro-architecture to produce appropriate strains in cells to promote the healing a wound. The apparatus includes a wound cover for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound, a vacuum source in fluid communication with the reservoir and suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound, and a porous structure positioned in contact with the wound for delivering micro-mechanical forces to localized areas of the wound. The porous structure comprises a three-dimensional film material having directional apertures formed therein.Type: GrantFiled: March 31, 2016Date of Patent: March 21, 2017Assignee: Smith & Nephew, Inc.Inventor: David G. Heagle

Patent number: 9597490Abstract: The present invention provides a microneedle, comprising a shaft of a monocrystalline material having at least three walls which are formed by a crystal plane of the monocrystalline material; and a tip connected to an end of the shaft comprising at least three walls which are formed by a crystal plane of the material. The material is preferably silicon. Two of the walls of the tip are formed by the same crystal planes as two walls of the shaft. These two walls are formed by a <111> crystal plane. Preferably, three walls of the tip are formed by a <111> crystal plane.Type: GrantFiled: June 24, 2009Date of Patent: March 21, 2017Assignee: U-NEEDLE HOLDING B.V.Inventors: Johan Willem Berenschot, Jeroen Mathijn Wissink, Niels Roelof Tas, Meint Jelle DeBoer

Patent number: 9597491Abstract: A device for the sealing connection of a pressure hose with a grip element of a surgical instrument. The device comprising at least one sealing element that, in an assembled state, is interposed between the grip element and the pressure hose in a connecting region to create a seal. A support element is provided and arranged in the connecting region in the interior of the pressure hose such that the sealing element is clamped, or can be clamped, between the support element and the pressure hose on one side and the grip element on the other side. In addition, a handle for a surgical device, in particular a cryogenic surgical instrument, comprising a grip element for holding the surgical instrument and comprising at least one pressure hose that is connected, or can be connected, with the grip element via the device for the sealing connection.Type: GrantFiled: August 17, 2011Date of Patent: March 21, 2017Assignee: Erbe Elektromedizin GmbHInventors: Hansjoerg Besch, Markus Amann, Christian Sick

Patent number: 9597492Abstract: A therapy delivery element configured for at least partial insertion in a living body. A braided structure surrounds the conductor assembly. A distal end of the braided structure is attached to an electrode assembly and a free floating proximal end is located near a connector assembly. An outer tubing surrounds the braided structure. The outer tubing includes a proximal end attached to the connector assembly and a distal end attached to the braided structure near the electrode assembly. A proximal tension force applied to the connector assembly acts substantially on the outer tubing and the conductor assembly and a proximal tension force applied to the free floating proximal end acts substantially on the braided structure.Type: GrantFiled: November 12, 2013Date of Patent: March 21, 2017Assignee: Nuvectra CorporationInventors: James Finley, John M. Swoyer
