  • Publication number: 20200261713
    Abstract: A medical lead may be fabricated using an electrode fixture configured to facilitate circumferential and axial alignment between electrodes of the lead. In one example, a method may include positioning an electrode fixture around at least one conductor of a plurality of conductors for a medical lead, wherein the electrode fixture at least partially retains an electrode assembly. The method may also include electrically coupling a portion of the at least one conductor with at least a portion of the electrode assembly at an attachment area defined by the electrode assembly when the electrode assembly is at least partially retained by the electrode fixture.

  • Publication number: 20190321630
    Abstract: An implantable segmented electrode structure may be configured to conduct electrical signals between elongated conductors of an implantable medical lead and respective portions of tissue of a patient. The implantable medical lead may extend from an implantable medical device that is implanted within the patient. The segmented electrode structure includes a plurality of separate electrode surfaces. The electrode surfaces are at a plurality of different axial positions and angular positions within the implantable segmented electrode structure. The segmented electrode structure additionally includes a plurality of prongs. The prongs extend axially from a proximal end of the segmented electrode structure through the segmented electrode structure. Each prong may electrically connect to one of the electrode surfaces. The prongs may terminate distally at respective electrode surfaces. Each prong may be configured to electrically connect to one of the elongated conductors.

  • Publication number: 20190117982
    Abstract: A method of forming a medical device lead connection element is described. The method includes positioning an end portion of a lead filar to overlap a lead end connection element such that the positioning creates mutual interference between the lead filar and the lead end connection element, and forming an interference configuration. Then melting the end portion of the lead filar to form a weld joint and allowint the end portion of the lead filar to move towards the end connection element.

  • Patent number: 9083053
    Abstract: An electric storage battery including a jelly roll type electrode assembly having a mandrel. The mandrel includes a positive portion, a negative portion and a removable portion. The mandrel can be planar, having two faces with grooves on the positive and negative portions. The grooves are dimensioned to accommodate positive and negative feedthrough pins. The mandrel is welded to the feedthrough pins by using a laser beam incident on the opposite face of the mandrel from the face on which the grooves and pins are located. The laser beam melts the mandrel such that molten mandrel material fills the grooves welding the feedthrough pins in place. Electrodes are wrapped around the mandrel using the removable portion to wind the mandrel. The removable portion can be detached. The mandrel allows tighter wrapping of the jelly roll assembly and increasing battery miniaturization.

  • Patent number: 9005802
    Abstract: An electric storage battery including a jelly roll type electrode assembly having a mandrel. The mandrel includes a positive portion, negative portion and removable portion. The mandrel has two faces with grooves dimensioned to accommodate positive and negative feedthrough pins. Electrodes are welded to the mandrel using an ultrasonic weld to the face on which the electrodes are attached. An additional weld is made to at least one ultrasonic weld using a through-mandrel laser weld, incident on the opposite face from which the ultrasonic weld. The laser melts the mandrel such that molten mandrel material fills the area under the foil at the area of the ultrasonic weld, the surface area of the foil being significantly increased by knurls formed by ultrasonic welding. Electrodes are wrapped around the mandrel using the removable portion to wind the mandrel. The mandrel allows tighter wrapping of the jelly roll assembly increasing battery miniaturization.
