    摘要： A cardiac lead adapted for fixation at least partially within a cardiac vessel. The lead includes, in one embodiment, an elongate lead body defining a proximal region and a distal region including a distal end region having at least one electrode and a distal tip. The distal end region is configured such that the electrode and the distal tip can be implanted in the cardiac vessel. Stiffening structures in the distal region of the lead are adapted to stiffen selected portions of the lead for fixation of the electrode within the cardiac vessel. In some embodiments, the stiffening structures include an implantable member adapted to be implanted in a lumen of the lead. In other embodiments, the stiffening structures include a sheath adapted to be deployed over the lead body. In still other embodiments, the stiffening structures are integral to the lead and/or the lead body.

    摘要： A medical electrical lead adapted to be at least partially implanted in a cardiac vessel includes a fixation feature operable to change from an undeployed configuration to a deployed configuration in which the fixation feature is adapted to engage an inner surface of the cardiac vessel. A tendon is disposed within a lumen of the lead and is operatively connected to the fixation feature and adapted to cause the fixation feature to change from the undeployed configuration to the deployed configuration for acute and/or chronic fixation of the lead. In one embodiment, the fixation feature includes a deflectable region of the lead which in the deployed configuration causes a surface of the lead body to engage the inner surface of the cardiac vessel. In another embodiment, the fixation feature includes a radially expandable structure for engaging the inner surface of the vessel in the deployed configuration.

    摘要： Some embodiments relate to a catheter system having a changeable or adjustable working length. The catheter system can comprise a proximal end, a distal end, and a first axial lumen configured to receive a guidewire formed through at least a portion of the catheter body. A first opening can be formed through a portion of the catheter body and be in communication with the first lumen. The sheath can be rotatable, axially movable, or otherwise changeable from at least a first position to a second position, wherein the sheath can substantially cover the first opening in the catheter body in the first position, and can substantially expose the first opening in the catheter body in the second position.

    摘要： A deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patient's anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter. The proximal ends of the inner catheter and recovery sheath include handle portions having snap mechanisms which hold the components together as the recovery system is being advanced into the patient's vasculature.
