Patent number: 9895159Abstract: A multiwire unit having a plurality of wire sections which are formed in one piece from a tubular piece whose tubular jacket is subdivided in at least an axial subsection by a plurality of axial slots. The wire pieces remain interlinked at a front end section at a distance to a front tube face, and assume a bent functional state downstream of the wire linking area in a defined functional state of the multiwire unit. The front wire linking area, in the functional state of the multiwire unit, is shaped to an essentially tipless front end closure. For this purpose, the axial slots end at an appropriate small axial distance to the front tube face. The multiwire unit may be formed as, for example, a wire basket unit or a wire filter unit for medical instruments.Type: GrantFiled: November 5, 2005Date of Patent: February 20, 2018Assignee: EPflex Feinwerktechnik GmbHInventor: Bernhard Uihlein

Patent number: 9778562Abstract: An imprint lithography template or imprinting stack includes a porous material defining a multiplicity of pores with an average pore size of at least about 0.4 nm. A porosity of the porous material is at least about 10%. The porous template, the porous imprinting stack, or both may be used in an imprint lithography process to facilitate diffusion of gas trapped between the template and the imprinting stack into the template, the imprinting stack or both, such that polymerizable material between the imprinting stack and the template rapidly forms a substantially continuous layer between the imprinting stack and the template.Type: GrantFiled: November 21, 2008Date of Patent: October 3, 2017Assignee: Canon Nanotechnologies, Inc.Inventors: Frank Y.

Patent number: 9358370Abstract: Embodiments hereof relate to a guidewire formed from an elongated shaft, at least a portion of the shaft having an outer layer, a plurality of channels formed through the outer layer, and an inner core. The outer layer is formed from a material non susceptible to erosion by an erosion agent and the inner core is formed from a radiopaque material susceptible to erosion by the erosion agent. When exposed to the erosion agent, core material adjacent to the channels is removed to form a pattern of integral radiopaque segments or markers with a plurality of voids therebetween. By controlling the location of channels and the rate of erosion of the core material, the pattern of integral radiopaque segments and voids allow for in situ measurement when viewed under fluoroscopy.Type: GrantFiled: March 12, 2012Date of Patent: June 7, 2016Assignee: Medtronic Vascular, Inc.Inventors: Mark L.
