  • Publication number: 20190209231
    Abstract: A tissue ablation device is provided including an inflatable balloon with a cavity. The tissue ablation device further includes a catheter with a lumen in fluid communication with the cavity of the inflatable balloon. The lumen of the catheter is configured to deliver a fluid to the cavity thereby causing the inflatable balloon to inflate and expand. The device also includes a heating element connected to the balloon, wherein the heating element is further connected to an electrical source. The heating element is configured to receive an electrical current from the electrical source. Further, the heating element is configured to raise the temperature of the inflatable balloon and the fluid when an electrical current is passed through the heating element.

  • Patent number: 9987194
    Abstract: Described in one aspect is a multi-cell or multi-chambered container for sealing various materials such as therapeutic or diagnostic agents, animal or human tissue, tissue samples, specimens, blood, genetic material, or any other material. The container includes seals formed by folding the wall of the elongate body transverse to the interior of the elongate body and maintaining the folded wall portions adjacent one another or joining them together. In another aspect, the container disclosed may be made according to a method involving creating multiple seals at various locations along the elongate body thus creating sealed voids or cells between the seals within the elongate body.

  • Publication number: 20180125573
    Abstract: A bipolar sphincterotome may include an elongate tubular member, a cutting wire, and a return path. The return path may include a conductive ink portion disposed on an outer surface at a distal portion of the tubular member. The return path may also include a return wire disposed within the tubular member that is electrically coupled to the conductive ink portion. In some example embodiments, the return wire may be disposed within a lumen configured to have two or more functions, one of which being to house the return wire. Additionally, in some example embodiments, the conductive ink portion may be circumferentially disposed on the outer surface to provide visual access to a wire guide lumen. Also, for some example embodiments, the bipolar sphincterotome may include two electrically isolated return paths.

  • Publication number: 20170007754
    Abstract: An endovascular assembly for improving vessel compliance by reducing the blood pressure needed to eject a given volume of blood. The assembly comprises a first expandable container, a balloon for example, positioned in the vascular system. The first container has a variable volume in response to blood flow in the vessel, and is fixed to at least one expandable attachment member. When the attachment member is expanded inside of the vasculature, the attachment member is preferably fixed inside the vessel. The assembly further comprises a second container, preferably having a fixed volume that forms a closed fluid system when fluidly connected to the first container. The connection between the first and second container permits a change in volume in the first container to flow fluid into the second container. The second container can be placed in a different location inside of the patient, preferably outside of the vessel.

  • Patent number: 9364277
    Abstract: A control unit controls delivery of RF energy generated by an RF generator to a medical device configured to perform a medical procedure. The control unit may be separate from the RF generator, and may have an input that may be attached to an output of the RF generator. The control unit includes switching circuitry that is closed while an amount of RF energy is transmitted through the control unit to the medical device. The switching circuitry opens when the amount of RF energy reaches a threshold level.

  • Publication number: 20140121750
    Abstract: A stent graft device that requires an anchor setting procedure to prevent migration of the stent, such as an endovascular anchor stent device used for treatment of an abdominal aortic aneurism, can be anchored to a blood vessel by electrosurgically disrupting portions of the blood vessel in situ to affix struts of the stent graft device to the vessel wall, replacing barbs which have been used in such devices. The stent graft device can have a wire frame and struts or a cannula stent frame body with struts cut from the cannula. The struts can be provided with openings which are filled with extracellular matrix material, which encourages and speeds ingrowth of the struts in the vessel wall.

  • Patent number: 8414633
    Abstract: A delivery system is provided with a balloon catheter having a stent mounted thereon. A retention wire is provided to restrain the stent on the balloon of the balloon catheter. The retention wire is coupled to the catheter adjacent the distal end of the stent and adjacent the proximal end of the stent. The retention wire extends along the length of the stent adjacent the outer surface thereof. Thus, the retention wire may restrain the stent from moving longitudinally during inflation of the balloon.
