Abstract: A catheter system for positioning of a medical instrument within a body. The catheter system includes a hub defining a main lumen therethrough for passage of the medical instrument. The catheter system also includes an elongate tubular member defining a lumen therethrough. The lumen of the elongate tubular member is in communication with the main lumen of the hub for further passage of the medical instrument. The elongate tubular member defines a first portion and a second portion. The catheter system also includes a reinforcement member that is fixedly coupled to and reinforces the elongate tubular member, the reinforcement member includes a first part, a second part, and a partition defined between the first and second parts. The first and second parts are adapted to selectively move away from each other along the partition to thereby move the first and second portions away from each other and to uncover the medical instrument.

Abstract: An implantable medical device delivers neurostimulation therapy to a patient according to a parameter set. A parameter set may consist of a number of programs that are delivered substantially simultaneously. When programming the implantable medical device for the patient, a clinician programmer may maintain a session log for the patient that includes a listing of programs delivered to the patient and rating information provided by a clinician and the patient for programs of the list. The listing may be ordered according to the rating information in order to facilitate the selection of programs for a parameter set. A program library that may include particularly effective programs organized according to a directory structure may be stored in a memory. One or both of the implantable medical device and a patient programmer may store usage information that provides an objective assessment of therapy use by the patient, and allows a clinician to later improve the therapy based on the usage information.

Abstract: A percutaneous neurological stimulation lead has at least a first lead body and a second lead body that interlock during implantation using interlocking elements. The first lead body has at least one first detail on the first lead body distal end that is configured to engage at least one second detail on the second lead body distal end that is complimentary to the first detail to mechanically couple the first lead body to the second lead body. Many embodiments of the implantable neurological stimulation lead with interlocking elements and its methods of operation are possible.
