  • Patent number: 10058330
    Abstract: One embodiment according to the present invention includes an occlusion device in which the support structure or frame expands circumferentially within the lumen to secure an expansile plug or embolic material. Once in place, the expansile plug or embolic material expands, thereby occluding the target lumen. Another embodiment according to the present invention includes a radially expandable support structure having a closed portion for capturing subsequently delivered embolic material, such as embolic coils. For example, the structure may have a closed portion at its distal end or at its middle (forming an hourglass shape). Additionally, the closed portion may be formed from the support structure itself or from a discrete, second layer that is attached within the support structure.

  • Patent number: 7591778
    Abstract: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and methods of using same. One embodiment provides a vascular graft that has a first end that is sized and configured to couple to a non-primary blood vessel and a second end that is fluidly coupled to a pump to conduct blood between the pump and the non-primary blood vessel. An outflow conduit is also provided that has a first end sized and configured to be positioned within the same or different blood vessel, whether primary or non-primary, through the vascular graft. The outflow conduit is fluidly coupled to the pump to conduct blood between the pump and the patient. The vascular graft may be connected to the blood vessel subcutaneously to permit application of the extracardiac pumping system in a minimally-invasive procedure.

  • Patent number: 7491163
    Abstract: A multilumen catheter that maximizes the blood flow into and out of the patient's vasculature while also providing for passive and/or active perfusion of tissue downstream of where the catheter resides in the vasculature. The inventive catheter comprises a proximal end, a first distal and a second distal end with first and second lumens extending from the proximal end to each of these distal ends to provide for blood circulation within one blood vessel or between two different blood vessels. The second lumen, and any additional lumens so desired, may be positioned coaxially with or radially around the first lumen. Redirecting means is provided at a distal end of at least one of said lumens for directing blood in a direction generally opposite of the direction of flow through said lumen.

  • Publication number: 20080275290
    Abstract: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and methods of using same. One embodiment of the intravascular extracardiac system comprises a pump with inflow and outflow conduits that are sized and configured to be implantable intravascularly through a non-primary vessel, whereby it may positioned where desired within the patient's vasculature. The system comprises a subcardiac pump that may be driven directly or electromagnetically from within or without the patient. The pump is configured to be operated continuously or in a pulsatile fashion, synchronous with the patient's heart, thereby potentially reducing the afterload of the heart.

  • Publication number: 20070270708
    Abstract: The invention provides methods, devices and systems for collecting breast ductal fluid comprising cellular material and other useful markers for analysis. The methods typically comprise access of at least one breast duct and collecting materials from that duct separate from all other ducts in the breast. The devices comprise ductal access devices that provide the opportunity to collect fluid from a single duct separate from all the other ducts in the breast. The systems employ the methods and devices that used together provide systems for analysis of a breast condition in a patient specific to accessed breast ducts. The methods, devices and systems are particularly useful for indentification of breast precancer or cancer in patient.

  • Publication number: 20070213690
    Abstract: A conduit for use with a blood pump can have a flared inner surface at an end of the conduit. In some embodiments, the conduit can include a strain relief member such as overmolded silicone. The strain relief member can maintain the profile of the flared inner surface. A conduit with a flared inner surface can be configured for connection to a blood pump via a connector. For example, the conduit can include an anchor member such as flange configured to engage with various components of a connector to connect the conduit to a fitting on a pump or another structure. In some embodiments, the conduit can be configured to connect to a blood conduit connector including a member such as a compression collet and a fitting such as a coupler. The connector can include a bayonet connection to facilitate rapid connection and disconnection of the conduit from a fitting.

  • Publication number: 20060281962
    Abstract: An extracardiac pumping system and method for using it supplement the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart. A battery powered pump may be implanted subcutaneously and attached to an inflow conduit fluidly coupled to a patient's femoral artery via a subcutaneous anastomosis connection. The pump draws blood from the inflow conduit and discharges it through an outflow conduit fluidly coupled to a second peripheral artery via another subcutaneous anastomosis connection. The battery may be charged extracorporeally and the pump may be operated in either a continuous or pulsatile fashion in synchronization with the patient's heart. The conduits can be housed in a multi-lumen catheter and a reservoir may be provided which fluidly communicates with the inflow conduits. An additional feature may keep blood traveling extracorporeally within the system at or near body temperature.

  • Publication number: 20060276682
    Abstract: A percutaneous cannula is provided that directs blood into a vessel of a patient. The cannula includes a main cannula portion and a tip portion. The tip portion directs blood-flow in a direction generally counter to the direction of flow through the lumen. The cannula is configured to prevent blood-flow exiting the distal end from immediately discharging against a wall of the vessel.

The inventive catheter comprises a proximal end, a first distal and a second distal end. Lumens extending from the proximal end to each of these distal ends provide for blood circulation within one or between two blood vessels. At least one aperture in one of the lumens positioned near the proximal end provides for active perfusion of blood to the patient's vasculature downstream of where the aperture resides in the vasculature when the catheter is inserted into the patient for treatment. The inventive catheter may comprise a third lumen positioned entirely within the patient's vasculature, providing passive perfusion of blood to the patient's vasculature downstream of where the third lumen resides in the vasculature when the catheter is inserted into the patient for treatment.
