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.

Abstract: Low resistivity, implantable electrical connectors and biomedical leads having the connectors mechanically coupled in a non-welded attachment to low resistivity wires to extend implanted device battery life. One electrical connector includes an electrically conductive housing having a longitudinal aperture and an inner facing circumferential channel. A spring disposed within the channel can contact an inserted electrode. The housing can include at least one hole adjacent a mechanically deformable side wall for mechanically securing an electrical conductor inserted within the hole. The low resistivity, implantable, biocompatible electrical connectors and leads can be used in neurological and cardiac applications.

Abstract: A selectively aspirating stylet assembly comprises a stylet having proximal and distal ends, the proximal end in fluid communication with a fluid supply and the distal end disposed at or near the end of a catheter, cannula or other generally tubular member that is to be inserted to a specified location within a patient's body, so as to create a fluid flow path from the fluid supply through the generally tubular member to the specified location. A valve assembly located within the fluid flow path is operable to close off a fluid column within the stylet assembly to facilitate placement of the tubular member within the body, and to control the flow of fluids within the assembly.

Abstract: A medical connector and method of using the connector to connect separate sections of medical tubing, especially tubing which is to be implanted in the human body. The connector includes generally cylindrical first and second end portions, the diameter of which are smaller than an enlarged middle portion. The end portions are sized to fit within the lumens of the tubing sections. The connection is made by grasping the enlarged middle portion and slipping each end portion into a respective tubing section until the tubing sections abut tubing stop surfaces located at each end of the enlarged middle portion. The enlarged middle portion makes the connector easy to handle and the tubing stop sections provide for accurate alignment of the connector between the tubing sections.
