Abstract: Medical leads have one or more openly coiled filars and a distal body coupled to the openly coiled filars. The openly coiled filars provide a lead with compliance and elasticity while the distal body provides the firmness needed for placement and support of the electrodes. The openly coiled filars may transition to a linear distal portion that extends to the distal body, and the distal body may have proximal tines that fold proximally to become adjacent to the linear distal portion of the filars. The openly coiled filars may instead extend to the distal body and the proximal tines may be laterally arced to then fold against the lateral surface of the coiled filars. The tines may fold distally during explantation to allow the distal body to release and exit the body.

Abstract: An implantable medical device (IMD) includes a housing that is configured to enclose internal components including at least a processor and a power source. The housing defines two major surfaces that are generally parallel to each other and one or more channels that are each configured to receive a lead and electrically couple the respective lead to the internal components, where each of the channels extend substantially straight in to the housing along an axis generally parallel to the two major surfaces. The housing may be configured to be mounted to a cranium of a patient such that at least one of the two major surfaces approximates a curvature of the cranium. The IMD may include one or more funneling walls that define a rounded and smooth transition from a sidewall of the housing to a surface that defines one or more mouths to the channels.

Abstract: Assemblies and methods provide for implantation of multiple medical leads to a defined space within the body, such as the epidural space, through a single entry. A catheter having multiple lumens or alternatively a single oblong lumen may be used. A distal end of the catheter enters the defined space through the single entry such that the distal ends of the multiple lumens or the oblong lumen are present in the defined space. Medical leads are introduced through the multiple lumens or the oblong lumen into the defined space. In some cases, the distal end of the catheter may be deflectable to direct the medical leads within the defined space. In other cases, sheaths may be present within each lumen of the catheter where the sheaths may be extended into the defined space and deflect to direct the medical leads that are being passed through a lumen of the sheaths.
