Publication number: 20190054274Abstract: A medical system tracks the position of a medical instrument within a body of a patient. The medical instrument includes an elongated flexible printed circuit and an electromagnet structure having a conductive coil wound around a core. A control circuit applies an excitation signal across the conductive coil. Electrical current running through the conductive coil (wound around the core) generates a magnetic field. A plurality of sensors sense parameters of the magnetic field and output sensor signals. The control circuit calculates the position of the medical instrument based on the sensor signals.Type: ApplicationFiled: March 2, 2018Publication date: February 21, 2019Inventor: Curtis S. King

Publication number: 20180145443Abstract: A multipart connector is employed in a system that tracks a medical device in the human body. The multipart connector includes a first connector portion and a second connector portion wherein the first connector portion pierces a contamination barrier to couple with the second connector portion. The medical device is a trackable structure having an integrated electromagnet circuit. The trackable structure is arranged to controllably produce a magnetic field. An interface is provided in the system to produce a positional representation of the trackable structure when the trackable structure is placed and moved within the human body. A magnetic field sensing device drives the integrated electromagnet circuit of the trackable structure tracks medical device and provides position information to the interface. The multipart connector electrically couples the magnetic field sensing device to the trackable structure.Type: ApplicationFiled: November 21, 2017Publication date: May 24, 2018Inventors: Samuel Peter Andreason, Steve Vincent, Curtis S.

Patent number: 8608891Abstract: A method to manufacture microfluidic sensors 100, 100?, 132, 280, 380, includes stacking a plurality of layers of material to form at least a first cap layer 102, a first channel layer 104, an interrogation layer 106, and a second channel layer 108. During assembly, ribbon sections of substrate layers are sandwiched to cooperatively align elements through-the-thickness of the sandwich. Individual sensors are then removed from the sandwich ribbon 504. A componentizing step includes forming one or more element for successive sensors spaced along the axial length of a ribbon of substrate material. Certain elements include electrically conductive patterned structures 250 printed onto a substrate using conductive ink and a printing process. Sometimes, the printing process places material in operable position to conduct electricity through the thickness of at least one ribbon. Other elements may include channels 112, 116; tunnels 114, and vias 260, 268.Type: GrantFiled: May 17, 2012Date of Patent: December 17, 2013Assignee: EI Spectra, LLCInventors: Harold E.

Patent number: 8072603Abstract: An apparatus for detecting particles of interest that are dispersed in a fluid mix, which typically includes other particles. The apparatus typically is associated with an interrogation platform arranged to operate in harmony with an opaque member having an orifice sized to promote single-file travel of the particles there-through. A currently preferred embodiment includes a light pipe configured to impinge stimulation-radiation substantially transverse to a direction of fluid flow through the opaque member. Particles of interest may be tagged using antibody-binding, fluorescing molecules. Stimulation radiation from the source causes the tagged particles to undergo a Stokes-shift emission of fluorescence. The resulting fluorescence is detected by the radiation detector and indicates passage of the particles of interest. One workable opaque member is advantageously included in a thin film assembly carried on a removable and disposable card that is adapted for reception in the interrogation platform.Type: GrantFiled: February 19, 2009Date of Patent: December 6, 2011Assignee: E I Spectra, LLCInventors: Harold E.
