Patent number: 7039470Abstract: A lead employing a connection between a conductor and an electric element is provided. The connection includes a conductive pad electrically connected to at least one conductor and the electric element electrically connected to the conductive pad. The conductive pad can further include an elongated element to connect the pad to the electric element. The method for connecting a conductor to an electric element is also provided. The method includes forming a groove in the insulator of a lead body to expose the conductor. Placing a conductive pad within the groove and electrically connecting a conductive pad to the conductor. An electric element is then placed over the conductive pad and the electric element is electrically connected to the conductive pad.Type: GrantFiled: September 26, 2000Date of Patent: May 2, 2006Assignee: MicroNet Medical, Inc.Inventor: Bradley J.

Publication number: 20050027339Abstract: An implantable lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body is disclosed. In one advantageous embodiment, a lead body assembly is formed by placing an inner layer of extrusion material on a mandrel, wrapping a plurality of conductors coated with extrusion material around the inner layer, and placing an outer layer of extrusion material over the plurality of conductors. Heat shrink tubing is placed over the lead body assembly and the lead body assembly is heated to melt the extrusion material. The melted extrusion material is compressed around the plurality of conductors. The assembly is then cooled and the heat shrink tubing is removed. The solidified extrusion material forms a protective wall that encapsulates the plurality of conductors in the lead body.Type: ApplicationFiled: July 29, 2003Publication date: February 3, 2005Applicant: MICRONET MEDICAL, INC.Inventors: Michael Schrom, Charles Lehman, Mark Schrom

Publication number: 20050027340Abstract: An implantable medical lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body is disclosed. In one advantageous embodiment, a lead body assembly is formed by preparing a first layer unitary body comprising a first plurality of conductors. An inner layer of extrusion material is placed on the first layer unitary body. A second plurality of conductors coated with extrusion material is placed on the inner layer. An outer layer of extrusion material is placed over the second plurality of conductors. Heat shrink tubing is placed over the assembly and the assembly is heated to melt the extrusion material. The extrusion material is compressed around the conductors. The assembly is cooled and the heat shrink tubing is removed. The solidified extrusion material forms a protective wall that encapsulates the first and second plurality of conductors in the lead body.Type: ApplicationFiled: July 29, 2003Publication date: February 3, 2005Applicant: MICRONET MEDICAL, INC.Inventors: Michael Schrom, Charles Lehman, Mark Schrom

Publication number: 20050027341Abstract: An implantable medical lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body are disclosed. A lead body assembly is formed by preparing a first layer unitary body comprising a first plurality of conductors wound in a first direction. An inner layer of extrusion material is placed on the first layer unitary body. A second plurality of conductors coated with extrusion material is placed on the inner layer. The second plurality of conductors is wound in a second opposite direction. An outer layer of extrusion material is placed over the second plurality of conductors. Heat shrink tubing is placed over the assembly. The extrusion material is heated and melted and compressed around the conductors. When the heat shrink tubing is removed, the solidified extrusion material forms a protective wall that encapsulates the conductors in the lead body.Type: ApplicationFiled: July 29, 2003Publication date: February 3, 2005Applicant: MICRONET MEDICAL, INC.Inventors: Michael Schrom, Charles Lehman, Mark Schrom

Patent number: 6721604Abstract: The present invention provides an implantable electrical lead having a reduced diameter and a relatively low resistance. The lead includes a lead body having at least one conductor manufactured from drawn-filled-tubing and having an elongated cross-sectional shape to confer a high cross-sectional area relative to the conductors thickness. The lead body insulates the conductor from contact with the patient and in the case of a plurality of conductors isolates the conductors from one another. The lead body may also include a lumen extending from the lead body's proximal to distal ends.Type: GrantFiled: July 27, 2000Date of Patent: April 13, 2004Assignee: MicroNet Medical, Inc.Inventors: Paul J. Robinson, Bradley J. Wessman, Mark Gerald Schrom
