摘要： An improved retrograde coronary sinus perfusion catheter includes a flexible, tubular catheter body and an inflatable balloon. The catheter body has proximal and distal ends and an interior lumen. The inflatable balloon is located adjacent the distal end of the catheter body and has proximal and distal edges. The improvement includes an echogenicity enhancement embedded within the catheter body. The echogenicity enhancement is adapted to reflect ultrasonic waves at a characteristic different from the catheter body.

摘要： An autoinflating catheter and balloon assembly having an autoregulating structure to prevent overinflation of the balloon as a result of variable fluid flow rates through the catheter lumen. A tight-fitting elastomeric balloon is provided on the distal end of the catheter body, and the assembly is constructed so that at least a portion of the fluid flow through the lumen is directed to the balloon to inflate it. As the balloon is inflated, more and more of the fluid flow through the catheter is discharged from the catheter, thereby preventing overinflation of the balloon.

摘要： There is disclosed an apparatus for the sanitary removal of an indwelling tube from an implantation site in a patient, comprising a tube adapter that is connectable to the indwelling tube. An impervious sleeve is fan-folded into a hub which extends around the tube adapter. In assembly the folded sleeve is retained by a shrink-wrapped plastic film. The sleeve can be extended for receiving the indwelling tube therethrough and to encompass the implantation site. The indwelling tube and the implantation site are isolated from the environment when the distal open end of the sleeve is extended and applied about the implantation site and the indwelling tube is withdrawn into the sleeve. A drawstring is provided for closing the distal end of the sleeve after the tube has been withdrawn. Embodiments are shown for removing a plurality of indwelling tubes in one operation, and for maintaining the lumen of the indwelling tube under suction or in connection with a drain during the removal operation.

摘要： An instrument including an elongated shaft and a non-conductive handle is disclosed. The shaft defines a proximal section and a distal section. The distal section forms an electrically conductive tip. Further, the shaft is adapted to be transitionable from a straight state to a first bent state. The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. The instrument is useful for epicardial pacing and/or mapping of the heart for temporary pacing on a beating heart, for optimizing the placement of ventricular leads for the treatment of patients with congestive heart failure and ventricular dysynchrony and/or for use in surgical ablation procedures.

摘要： Methods and devices for forming a lesion in a target tissue having a cavity within. A first RF electrode and a second RF electrode can be coupled to opposite poles of an RF current source. The second electrode can be inserted into the tissue cavity and expanded to contact the target tissue from within. The first electrode can be externally disposed against the target tissue while applying RF current between the first and second electrodes to ablate the target tissue. Some methods are directed to ablating tribiculated atrial wall tissue to treat atrial fibrillation. The second electrode can contact the tribiculated tissue directly from within to provide a direct path between the two electrodes. In some methods, the second electrode is inserted through an incision made to remove an atrial appendage. The methods can provide deeper, narrower lesions relative to those made using remote, indifferent electrodes. Atrial fibrillation ablation procedures can be performed using the invention, requiring fewer incisions than conventional methods.
