Publication number: 20220040465Abstract: A uniformity control membrane can be securely engaged against an upstream side of a microneedle array and configured so that resistance to flow through the uniformity control membrane is substantially greater than the resistance to flow through the microneedle array. These differences in flow resistance can facilitate uniform administration of a liquid formulation into the patient's skin across a broad area and at a relatively low pressure, such as by way of capillary action. The administration of the liquid formulation into the patient's skin across the broad area can result from the liquid formulation being administered by way of at least a majority of the microneedles of the microneedle array.Type: ApplicationFiled: October 25, 2021Publication date: February 10, 2022Inventors: Andrew T. Baker, Russell F. Ross, Elizabeth Deibler Gadsby, Luke Hagan

Patent number: 11235101Abstract: A gas extraction device for a fluid delivery apparatus includes a first layer and a vent membrane coupled to the first layer. The vent membrane enables a gas to pass through the vent membrane and prevents a fluid from passing through the vent membrane. The gas extraction device also includes a second layer coupled to the vent membrane opposite the first layer. The second layer has a first channel formed therethrough. In addition, the gas extraction device includes an impermeable membrane coupled to the second layer opposite the vent membrane. The first channel is configured to receive a fluid having a gas dispersed therein. The fluid is pressurized to move the fluid through the first channel against the vent membrane and to move the gas through the vent membrane.Type: GrantFiled: December 22, 2020Date of Patent: February 1, 2022Assignee: Sorento Therapeutics, Inc.Inventors: Russell F.
