Abstract: An implantable lead body for a medical device with improved conductor lumens separates and insulates conductors while permitting access to the conductors through the implantable lead outer surface. The implantable lead comprises a lead body, a stylet lumen, at least one conductor lumen, and at least one axial slit in the lead body. The lead body has a proximal end, a distal end, an internal portion, and an external portion. The stylet lumen is formed in the internal portion. The conductor lumen is formed in the internal portion and positioned near an outer surface of the internal portion such that there is only a web between the conductor lumen and the outer surface of the internal portion. The axial slit is formed in the lead body distal end between the conductor lumen and the outer surface of the internal portion.

Abstract: A one-piece, single-use disposable device for transurethral needle ablation (TUNA) of prostate tissue to alleviate BPH is disclosed. The device may include a flexible catheter tip including a rigid core and a flexible tip. The device may also include a single use lockout to help ensure that the device is used to perform only one ablation procedure on a single patient. The device may further include a simplified needle deployment mechanism and/or an automatic needle retraction mechanism.

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: An implantable neurological stimulation lead with improved stylet handle comprises a lead body, at least one conductor, at least one electrical contact, at least one electrode, a stylet wire, and a stylet handle. The lead body has a body proximal end, a body distal end, and a stylet lumen. The conductor is contained in the lead and extends from the body proximal end to the body distal end, and the conductor is electrically insulated. The electrical connector is carried on the body proximal end and electrically connected to the conductor. The electrode is carried on the body distal end and electrically connected to the conductor. The stylet wire is configured for insertion into the stylet lumen to stiffen the lead body. The stylet handle is selectively coupled to the stylet wire. The stylet handle has a lead carrier and at least one gripper carried in the lead carrier configured to grip the lead body at a selected point along the lead body or lead proximal end.

Abstract: Implantable leads, lead assemblies, and methods for implanting the leads into the human body. The lead can include numerous distal electrical contacts for sensing and/or stimulation as well as numerous proximal contacts for connecting to a lead extension and/or an implantable pulse generator. The lead includes a stylet lumen extending between a side-wall stylet entrance port and the lead distal region. Some leads further include a stylet guide disposed near the stylet opening for fluoroscopic visualization and/or insuring proper insertion and distal advancement of the stylet within the lead. In use, the stylet can be inserted through the lead stylet port to stiffen only the distal portion of the lead, and the distal portion of the lead inserted through an introducer needle into the human body. The stiffened distal portion of the lead can be short and easily controllable.

Abstract: Low resistivity, implantable electrical connectors and biomedical leads having the connectors mechanically coupled to low resistivity wires in a non-welded attachment to extend implanted device battery life. One implantable electrical connector has an inner longitudinal aperture and two opposed flanges angled away from the longitudinal axis and coupled through a radially flexible inner circumferential wall to form a single piece, low resistance path. An elastic member can urge the flexible inner circumferential wall portion inward. In one connector, the electrically conductive, flexible inner wall portion can resiliently contact an inserted electrode. The connector body can include at least one hole adjacent a mechanically deformable sidewall 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.
