A system and method are disclosed that track a deliverable to a user. The system includes an identifier or tag secured to the deliverable, a computer system for interrogating the identifier, and a personal device in communication with the computer system, wherein the personal device is held by the user at the time the user is administered the deliverable to detect the unique identity associated with the identifier device and confirms delivery of the deliverable to the user. The method includes attaching an identifiable tag that produces a unique signature to the deliverable, interrogating the tag at about the time of delivery to the user, and confirming that the user has been administered the deliverable through detecting the identifiable tag.

Methods for evaluating motion of a cardiac tissue location, e.g., heart wall, are provided. In the subject methods, timing of a signal obtain from a strain gauge stably associated with the tissue location of interest is employed to evaluate movement of the cardiac tissue location. Also provided are systems, devices and related compositions for practicing the subject methods. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy.

The present invention is directed to a delivery catheter for use in deploying a vascular prosthesis having a self-expanding radial distal section joined to a helical section for use in a wide range of interventional applications. The delivery catheter comprises an elongated member having a balloon disposed adjacent to a distal end of the member, means for engaging the distal section of the vascular prosthesis against axial translation, and a sheath that restrains the vascular prosthesis against the elongated member during transluminal delivery. The balloon also may be used to perform angioplasty of a stenosis located within the vessel prior to deployment of the vascular prosthesis. Methods of using the delivery catheter of the present invention also are provided.

One embodiment of the present invention provides a system for automatically optimizing CRT procedures using a multi-electrode pacing lead. During operation, the system performs a first set of iterations to select one or more satellites on one or more pacing leads inserted in a patient. A pacing lead includes a plurality of pacing satellites, and a pacing satellite includes a plurality of electrodes that can be individually addressed and used for transmitting or detecting electric signals. The system then performs a second set of iterations to select one or more electrodes on the selected satellites. The system further performs a third set of iterations to select one or more timing configurations for pacing signals transmitted through one or more of the selected electrodes.

According to the present invention, improved apparatus and methods are provided for applying surgical clips to body tissue in inaccessible places and at various angles with particular usefulness in laparoscopic surgery. In one embodiment, the apparatus comprises a shaft having a distal end and a proximal end; means for advancing clips along the shaft toward the distal end with the legs of the clip oriented in a distal direction; means at the distal end of the shaft for rotating the clips relative to the shaft to orient the legs in a lateral direction and means for closing the legs of the clips after the rotation. The means for advancing usually comprises a movable belt disposed in the shaft having a plurality of retainers for holding clips; means for closing typically includes an anvil mounted at the distal end of the shaft and a hammer movable against the anvil. In another embodiment the apparatus further comprises means disposed at the proximal end of the shaft for actuating the hammer, which usually consists of a trigger pivotally mounted to a handle. In an exemplary embodiment, the trigger is ratcheted in stages, wherein one stage advances a clip, a second stage rotates a clip and a third stages closes a clip.

摘要:
Methods of highly selective cardiac tissue stimulation and devices for practicing the same, e.g., implantable segmented electrode devices, are provided. The methods and devices provide a previously unavailable high phrenic nerve capture voltage paired with a low pacing capture voltage threshold. The subject methods and devices provide a number of benefits. For example, patients who previously would have been required to have their resynchronization device turned off due to phrenic nerve capture will now be able to reap the benefits of resynchronization therapy.
