  • Patent number: 8926635
    Abstract: A novel occluder application and clip device for treatment of embolic stroke caused by atrial fibrillation uses multiple sutures in a non directional handle to affix the occlusion device to the applicator and manipulate the occluder from an open and receiving position to a closed and occluding position. The occluder is retained in place by a clamping means related to locks retainers, resilient material or otherwise. An actuator mechanism is used to manipulate the occluder to a locked or occluding position. The applicator with the occluder attached has a low profile and remote manipulations to allow the occluder to be delivered to the clamping location within a patient through a small incision or delivery port such as a trocar cannula or the like.

  • Patent number: 8623010
    Abstract: 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.

  • Patent number: 8439858
    Abstract: An arterial line blood filter for use in extracorporeal blood circuits during heart bypass surgery has, among other components, a housing with a cap portion, a base portion, and a generally cylindrical wall portion. The blood filter has a filter element disposed within the housing. An inlet is positioned at an upward angle with respect to the housing and includes an opening in the generally cylindrical wall portion in fluid communication with the inlet chamber. In some embodiments the position of the inlet limits the pressure drop and prime volume of the filter. According to one embodiment, the cap portion has an upwardly sloping inner surface and there is a vent in the cap portion. The inner surface of the cap portion can have a projection proximate the vent configured to limit immobilization of gaseous microemboli within the inlet chamber.

  • Patent number: 7909794
    Abstract: 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.

  • Patent number: 7871409
    Abstract: 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.
