The invention provides an interface assembly for delivering an ionized analyte from an ionization apparatus into an ion mobility spectrometer. This allows analysis of biological and non-biological samples, even non-volatile solids, via differential mobility spectrometry, without fragmentation of molecules. The invention also provides portable sample analysis systems that operate at ambient pressure. Systems of the invention may be used for high molecular weight species detection, for example, drinking water contaminants, pathogenic biological agents, bio-organic substances, non-biological material, peptides, proteins, oligonucleotides, polymers, bacteria, and hydrocarbons.

US Classification:
604514, 604264, 604246, 604151, 604247
Abstract:
An implantable drug delivery apparatus for delivering a drug into a bodily fluid in a bodily cavity of a patient over a period of time includes a drug supply reservoir to supply drug into a delivery channel and an actuator for delivering the drug to a predetermined location in the bodily cavity of the patient, such as, for example, a cochlea of a human ear. The drug is loaded into the delivery channel while producing substantially negligible flow at an outlet of the delivery channel.

International Classification:
A61M 1/16
US Classification:
604522, 422 48, 435 2
Abstract:
A device and method for oxygenating blood is disclosed herein. The device includes a plurality of passive mixing elements that causes a fluid to mix as it flows through the device. The passive mixing elements continually expose new red blood cells to the portion of the flow channel where oxygenation can occur. Accordingly, in some implementations, the device and method uses less blood to prime the device and allows for the oxygenation of blood with a substantial shorter flow channel when compared to conventional oxygenation methods and devices.
Compact Hydraulic Manifold Structure For Shear Sensitive Fluids

International Classification:
A61M 1/34 F17D 1/00
US Classification:
21032172, 137544
Abstract:
An compact hydraulic manifold for transporting shear sensitive fluids is provided. A channel network can include a trunk and branch architecture coupled to a bifurcation architecture. Features such as tapered channel walls, curvatures and angles of channels, and zones of low fluid pressure can be used to reduce the size while maintaining wall shear rates within a narrow range. A hydraulic manifold can be coupled to a series of microfluidic layers to construct a compact microfluidic device.
Hand Tool With Integrated Micropump And Drug Reservoir For Intracochlear Drug Delivery

International Classification:
A61M 1/00 A61M 39/24
Abstract:
The present disclosure provides a handpiece for trans-canal delivery of a therapeutic substance to the inner ear. The handpiece can be inserted into the middle ear via a surgical tympanotomy approach. The handpiece can be integrated with a micropump and a fluid reservoir. The handpiece can enable a controlled injection of a therapeutic substance directly through the round window membrane and into the inner ear. The direct delivery of the therapeutic substance to the inner ear can enable the delivery of a precise amount of therapeutic substance into the inner ear. The micropump can include a self-contained fluid reservoir that can provide predetermined volumes of fluid to precise areas of the patient.
