Publication number: 20090318799Abstract: This patent document discusses assemblies and methods for remotely detecting a position of a surgical instrument in the presence of a magnetic field. In varying examples, a position detection system includes an encoder coupled to move in concert with the instrument. The encoder includes an a translucent substrate and light blocking indicia disposed thereon. A light source and a light detector array are effectively disposed outside of the magnetic field. Light from the light source is carried to an encoder first side using an input optical fiber, while the light passing through the encoder is received at an encoder second side by an output optical fiber. The light received by the output optical fiber is transmitted to the light detector array, which converts the received light to position representative electrical signals. Such signals are subsequently transmitted to a control module adapted to formulate and convey a position of the instrument.Type: ApplicationFiled: August 31, 2009Publication date: December 24, 2009Applicant: MEDTRONIC, INC.Inventors: DAVID WURMFELD, MATTHEW S.

Publication number: 20090287141Abstract: A device, system and method deliver an agent to a soft mass, such as an area of the body, and more specifically the brain. One aspect includes creation of one or more channels, tunnels or grooves in tissue using a relatively small diameter, minimally-invasive stylet and then removing the stylet prior to infusion. The stylet-created channels become paths of increased hydraulic conductivity, through which the infusate will tend to flow and produce a predictable infusion pattern. Infusate will be carried into these channels with relatively low resistance, and then infuse outward from these channels into the surrounding tissue. By carefully positioning these channels, one can control and modify the preferred paths and duration of distribution.Type: ApplicationFiled: May 13, 2008Publication date: November 19, 2009Inventors: Matthew S.
