    摘要： A therapy delivery element adapted to be implanted into a living body. The therapy delivery element includes an electrode portion with a plurality of electrodes. At least one elongated lead body is attached to the electrode portion. The elongated lead body includes a stylet coil having a stylet coil lumen. The stylet coil extends within the elongated lead body and along at least a portion of the electrode portion. A conductor assembly with a plurality of insulated electrical conductors is braided to extending around the stylet coil and to electrically couple to one or more of the electrodes. The conductor assembly includes an inner lumen with a diameter greater than an outside diameter of the stylet coil. Axial elongation of the elongated lead body reduces the inner diameter of the conductor assembly. A low durometer insulator extends around the conductor assembly. A stylet sized to slide freely within the stylet coil lumen is provided for use during implantation of the therapy delivery element into the living body.

    摘要： Methods and apparatus for ablating a target tissue are discussed. Such methods and apparatus include those that simplify tissue ablation. For example, a tissue ablation device having an actuator, such as a trigger mechanism, coupled to a power source and an electrode is discussed. A single step of engaging the actuator causes the electrode to be introduced into the target tissue and causes energy to be delivered from the power supply to the tissue via the electrode. By way of additional example, a tissue ablation device having an actuator coupled to a fluid source and an electrode is discussed. A single step of engaging the actuator causes conductive fluid to flow from the fluid source to the target tissue location and causes the electrode to be introduced to the target tissue location. The fluid source may be a conductive fluid, such as saline, which may increase the efficiency of ablation. Various other configurations and methods that simplify tissue ablation are also discussed.

    摘要： The disclosure describes a system that may be used to deliver ablation therapy to a target tissue within a patient. The system uses a flexible catheter to navigate through a passage and reach a target tissue. Once at the desired location, a side of the flexible catheter is forced against a wall of the passage to allow a needle to be extended from the side of the flexible catheter and into the target tissue. A pull-wire or inflatable balloon may be used as the control mechanism that forces the flexible catheter against the passage wall. In the case of the pull-wire, the flexible catheter may also be steered through the passage. As an example, the flexible catheter may be inserted into the urethra and the needle may be deployed into the prostate to treat benign prostatic hypertrophy (BPH).

    摘要： The disclosure describes an axial lead connector assembly for an implantable medical device (IMD). The lead connector assembly facilitates electrical connection between an implantable medical lead and circuitry contained within the housing of an IMD. A connector header defines an axial stack bore to receive an axial stack of in-line connector components. The connector components define a common lead bore to receive a proximal end of an implantable lead. The in-line stack of connector components may include seals, electrical connector elements, a strain relief, and a locking device, each of which defines a passage that forms part of the lead bore.

    摘要： Delivery elements, including needle electrodes and sheaths of tissue ablation devices, containing a conductivity-enhancing agent are discussed. The delivery elements contain a body member and optionally one or more coating layers. The conductivity-enhancing agent is disposed on or in the body member and/or at least one of the one or more coating layers. The conductivity-enhancing agent is capable of eluting from the delivery element when the delivery element is contacted with bodily tissue or fluid and increases conductivity of the tissue, making tissue ablation more efficient.

    摘要： An implantable medical electrical lead particularly for stimulation of the sacral nerves comprises a lead body extending between a distal end and a proximal end, and the distal end having at least one electrode of an electrode array extending longitudinally from the distal end toward the proximal end. The lead body at its proximal end may be coupled to a pulse generator, additional intermediate wiring, or other stimulation device. A fixation mechanism is formed on or integrally with the lead body proximal to the electrode array that is adapted to be implanted in and engage subcutaneous tissue, particularly muscle tissue, to inhibit axial movement of the lead body and dislodgement of the stimulation electrodes. The fixation mechanism comprises a M tine elements arrayed in a tine element array along a segment of the lead proximal to the stimulation electrode array. Each tine element comprises at least N flexible, pliant, tines, each tine having a tine width and thickness and extending through a tine length from an attached tine end to a free tine end. The attached tine end is attached to the lead body from a tine attachment site and supports the tine extending outwardly of the lead body and proximally toward the lead proximal end. The M×N tines are adapted to be folded inward against the lead body when fitted into and constrained by the lumen of an introducer such that the tine free ends of more distal tines of more distal tine elements are urged toward or alongside the attached tine ends of the adjacent more proximal tines of more proximal tine elements, and the folded tines do not overlap one another.
