  • Patent number: 8244379
    Abstract: Certain aspects of the disclosure pertain to methods and apparatus for providing positive fixation of medical components to a portion of incised pericardial tissue. Accordingly, a resilient member protrudes through an incision in the pericardium and produces a positive biasing force to adjacent pericardial tissue against a side surface of an attached body structure. The resilient member can optionally be compressed during implantation and then relaxed to thereafter provide the positive biasing force. Diverse medical components can thus be safely and reliably chronically deployed into the pericardial space, including without limitation, cardiac sensing/pacing, defibrillation and/or cardioversion electrodes, mechanical and/or metabolic sensors and the like. More than one body structure can be linked to a single medical electrical lead and the medical components can couple within and/or upon a portion of the body structure, the resilient member, and the lead in myriad configurations.

  • Patent number: 7212867
    Abstract: A directional brain stimulation lead assembly provides a lead body and an insulating member defining one or more windows that selectively expose portions of electrodes carried by the lead body to produce a directional stimulation current field. The lead assembly can achieve more effective localization of electrical stimulation to very small brain targets, and thereby reduce the incidence of material side effects caused by collateral stimulation of brain tissue adjoining a desired brain target. In addition, the directional lead can sense brain activity on a more localized basis.

  • Publication number: 20060184222
    Abstract: A medical electrical lead, a system for providing electrical stimulation or sensing using such a lead, and methods of implanting, making and using same are described. The lead includes a rapidly connectable and/or interchangeable distal line that may be attached to a connector located distally from a distal end of a stimulating electrode. The rapidly connectable or interchangeable line may be sutured to a patient's muscle or other tissue. A physician may select a distal suture line of the present invention on the basis of the desired characteristics of the line, and then connect, secure or attach same to the lead body just prior to the surgical operation in which the stimulating or sensing medical electrical lead of the present invention is to be employed. The desired characteristics of the suture line may relate to thickness or diameter, length, the material from which the line is made, biodegradability, and the like.

  • Patent number: 6980863
    Abstract: The invention is directed to neurological lead extensions without set screws, set screw blocks, or set screw inserts. Such elimination of set screws, blocks and inserts can reduce the amount of metal and ferromagnetic material in the extension. The neurological lead extension may include a proximal end configured to couple to a neurological device and a distal end configured to couple to an implanted neurological lead. A set of electrical contacts are disposed in proximity to the distal end to provide electrical contact to an inserted end of the implanted neurological lead. Various elements and structures are described which can mechanically secure the inserted end of the implanted neurological lead to the distal end of the extension.

  • Publication number: 20050165324
    Abstract: A sensor is provided on a lead and senses various physical parameters that are indicative of a desired anatomical target, such as the coronary sinus. The data from the sensor is used to navigate to the anatomical target and/or confirm that the anatomical target has been reached. In one embodiment, the sensor is a temperature sensor and increased temperature values in and around the coronary sinus are used for navigational purposes.

  • Patent number: 6434431
    Abstract: The present invention relates to an intramuscular medical electrical lead, a system for providing electrical stimulation or sensing using such a lead, and methods of implanting, making and using same. The lead includes at least a first fixation member disposed distally or proximally from a sensing or stimulating electrode, and may further include a second fixation member disposed at the opposite end of the electrode form the first fixation member. The fixation members permit the electrode to be reliably and fixedly secured within a patient's muscle tissue at a desired site, and to remain so secured for a predetermined suitable period of time.

  • Publication number: 20020019629
    Abstract: A medical system and corresponding method for forming intramyocardial channels in cardiac tissue of a patient's heart are disclosed. The channel forming system may be configured in two basic embodiments: (a) a first embodiment where a transluminal steering and delivery system comprises a guide catheter or sheath which functions largely apart from and independent from other components of channel forming system (with the notable exception of a means for extending and retracting a piercing means from a distal end of the guide catheter or sheath, and (b) a second embodiment where a transluminal steering and delivery system is integrated into and combined with other components of the channel forming system, such as a piercing means, means for delivering radio-frequency energy to the piercing means, and temperature sensing means.
