摘要： An implantable electrical stimulation lead includes an integrated fixation mechanism that expands upon implantation of the lead to fix the lead relative to a target tissue site, such as tissue within the epidural region proximate the spine or the sacral foramen. The fixation mechanism may include one or more expandable wire-like elements, which may be configured in a substantial helical shape. The wire-like elements may be formed from an elastic or super-elastic material, and expand radially outward when a restraint mechanism is removed following implantation of the lead.

摘要： Suture anchors for securing therapy delivery elements, such as stimulation leads or catheters, within a living body. The suture anchor includes an inner sleeve constructed with an inner layer of a softer, more pliable material that easily conforms to the therapy delivery element to reduce slippage and an outer layer constructed from a harder, stiffer durometer material that protects the therapy delivery elements from damage due to over-tightening the tie down sutures. A suture material located in the suture groove is tensioned to apply a radial compressive force. The reinforcing structure spreads the radial compressive force along a greater surface area of the therapy delivery element.

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： A therapy delivery element configured for at least partial insertion in a living body. A braided structure surrounds the conductor assembly. A distal end of the braided structure is attached to an electrode assembly and a free floating proximal end is located near a connector assembly. An outer tubing surrounds the braided structure. The outer tubing includes a proximal end attached to the connector assembly and a distal end attached to the braided structure near the electrode assembly. A proximal tension force applied to the connector assembly acts substantially on the outer tubing and the conductor assembly and a proximal tension force applied to the free floating proximal end acts substantially on the braided structure.

摘要： Devices and methods for placing medical leads using minimally invasive techniques. One lead includes a lead body connected to a lead head having an aperture for providing fiber optic access to the interior of a helical electrode. The fiber optic shaft may be disposed within or along-side a drive shaft releasably coupled to the head to rotate the head. The drive shaft and lead body may be delivered using a delivery catheter. The delivery catheter can be advanced though a small incision to the target tissue site, and the site remotely visualized through the fiber optic scope extending through the lead head aperture. Some catheters include a distal mapping electrode readable from the catheter proximal portion or handle. The lead head can be rotated, rotating the helical electrode into the tissue, and the catheter, drive shaft, and fiber optic probe removed. In one use, epicardial pacing leads are placed on the posterior surface of the heart, aided by visualization and mapping to obtain optimal electrode placement and patient outcome.
