The present invention generally relates to heart treatment systems. In some aspects, methods and systems are provided for facilitating communication between implanted devices. For example, an implantable cardiac rhythm management device may be configured to communicate with an implantable blood pump. The implantable cardiac rhythm management device may deliver heart stimulation rate information in addition to information associated with any detected abnormalities in heart function. In response, the pump may be configured to adjust pumping by the pump to better accommodate a patient's particular needs.

Communication methods and architecture for heart treatment systems

Adjusting pump protocol based on irregular heart rhythm

In one general aspect, a cuff for attachment to a heart includes an attachment component configured to engage a blood pump to attach the cuff to the blood pump and a sewing ring for attachment to the heart. The sewing ring is coupled to the attachment component, and the attachment component and the sewing ring each define a central opening configured to admit an inflow cannula of a blood pump. The sewing ring comprises a member that provides rigidity to flatten a portion of a myocardium of the heart when the cuff is attached to the heart.

Ventricular cuff

A multi electrode catheter for non contact mapping of the heart having independent articulation and deployment features.

Cardiac mapping catheter

A fluid treatment system for a percutaneous cable and methods of assembly and use are described herein. In one aspect, the fluid treatment system includes a delivery tube comprising a distal end and a proximal end. The distal end is configured to surround at least a portion of the percutaneous cable. The percutaneous cable extends from within a patient to outside the patient through tissue at an exit site. The proximal end is connectable to a fluid source. Fluid from the fluid source is configured to be delivered to the exit site through the delivery tube. The fluid treatment system includes an anchor coupleable to the percutaneous cable to secure the percutaneous cable to the tissue at the exit site.

Fluid treatment system for a driveline cable and methods of assembly and use

A mapping catheter including an elongate catheter body extending from a proximal end to a distal end, a handle connected to the proximal end of the catheter body, an electrode array connected to the distal end, a deployment shaft, and an irrigation system. The catheter body includes at least one lumen. The irrigation system includes a manifold and a thin, polymeric irrigation tube. The manifold is disposed within the handle and is connectable to a source of irrigation fluid. The irrigation tube is connected to the manifold and extends around the deployment shaft from the manifold to the distal end of the catheter through the catheter body lumen. The irrigation tube forms an annular lumen between an inner surface of the irrigation tube and an outer surface of the deployment shaft. The annular lumen is configured to carry irrigation fluid from the manifold to the array.

Catheter with annular lumen to provide distal flushing

A steering control apparatus includes a first wire and a second wire extending from a distal end of a catheter to a steering assembly. The steering assembly includes a steering knob disposed at an exterior of the handle, a cylindrical steering shaft projecting from the steering knob and into the interior of the handle, a first cylindrical drum disposed within the handle and connected to the first wire, and a second cylindrical drum within the handle and connected to the second wire. The first drum is configured to engage the steering shaft to produce tension on the first wire. The first drum is coaxial with the steering shaft. The second drum is configured to engage the steering shaft to produce tension on the second wire. The second drum is coaxial with the steering shaft and axially adjacent to the first drum.

Bidirectional steering control apparatus for a catheter

A modular driveline includes a modular portion including a cable and a connector, the cable having terminations, and a percutaneous portion including a cable and a connector, the cable having terminations. The percutaneous portion connector couples to the modular portion connector, and cable terminations at the connectors are captured in the connectors by potting. The cable can include an inner member, conductors disposed about the inner member, a covering about the conductors, a layer extruded onto the covering, an armor braid over the extruded layer, and an outer jacket extruded over the armor braid.
