摘要: The present invention is directed to pumps, device, and methods for handling liquids on a microscale. Specifically, a microfluidic pump is described in which liquid in a fluid microchannel may be moved in either direction due to the diffusion of a gas through a diffusion membrane in response to a pressure differential applied through a control microchannel. This pump can provide non-contact, and optionally, bi-directional movement of liquid in microfluidics platforms, as well as bubble-free filling of dead-end microchannels and reservoirs.

摘要: Methods, devices, apparatus, assemblies, and kits for performing a vascular anastomosis are disclosed. A device for a vascular anastomosis includes tissue engaging portions that can move between at least two configurations. In some embodiments, the tissue engaging portions move without the aid of moving parts, while in other embodiments the tissue engaging portions extend from one or more movable wings. The tissue engaging portions may be separated by a first distance when in a pre-deployment configuration and by a second distance when in a deployed configuration. A method includes engaging a plurality of tissue engaging members of a coupling device against first end tissue. After selectively engaging the tissue engaging members and first end tissue, the first end tissue is stretched by at least moving the tissue engaging members. The stretched first end tissue is coupled to the second end tissue by mating the coupling device to a mating anastomosis device.

摘要: A magnetic field generation system includes first (28a) and second (28b) magnetic flux concentrators spaced apart to form a sample volume (30). A first set of auxiliary permanent magnets (10a, 10b) can be symmetrically oriented about and in contact with a portion of the first magnetic flux concentrator (28a). Similarly, a second set of auxiliary permanent magnets (10c, 10d) can be symmetrically oriented about and in contact with a portion of the second magnetic flux concentrator (28b). The first(10a, 10b) and second (10c, 10d) sets of auxiliary magnets can be magnetically associated via the first (28a) and second (28b) magnetic flux concentrators. Magnetically soft shunts (38) can be movably oriented to allow variation of the magnetic field strength across the sample volume by disrupting the field flux across the magnetic flux concentrators.

摘要: The present disclosure provides apparatuses, systems, and methods involving a spotter for depositing a substance on a submerged surface. The spotter comprises an outlet cavity defined at least in part by a spotting orifice, a first opening, and a second opening. The spotter also comprises a first conduit fluidly coupled to the first opening and a second conduit fluidly coupled to the second opening. The spotter is adapted so that fluid flowing through the first conduit and the second conduit is communicated among the first opening, the second opening, and a submerged deposition surface when the sealing orifice is sealed against the submerged deposition surface to form a deposition spot on the submerged deposition surface. The submerged deposition surface is within a liquid such that the liquid covers the deposition spot upon removal of the orifice from the deposition surface.
