    摘要: A multiple lumen access device for use in providing a single entry port into the human body for selectively introducing medical implements therethrough and for providing simultaneous auxiliary access into the body. The multiple lumen access device includes a multi-lumen sheath which may have an outer tube and structure defining a device lumen located therein. The inner structure may be an inner wall or inner tube. The outer tube and inner structure are located so as to define at least one auxiliary lumen. Some embodiments include flexible inner walls which can be flexed between relaxed and expanded/contracted positions wherein the relative cross-sectional areas of the device lumen and auxiliary lumens are varied. The access device further includes a valve which provides sealing of the device lumen. The valve may be provided in a lumen junction housing or separate from the housing either permanently or removably connected with the device lumen. Alternatively, a multi-lumen sheath may be passed through a valve leading to a conventional introducer. The valve may also be molded separately as a rigid insert and retained in a cavity formed in a flexible junction housing. In other embodiments, the multiple lumen access device is formed by introduction of the elongated implement coaxially within a tubular single lumen sheath.

    摘要: 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.

    摘要: A perfusion cannula system for directing blood through the vasculature of a patient comprises a cannula body having a proximal end, a distal end, and at least one lumen extending therebetween. The perfusion cannula system enhances blood flow past the cannula when the cannula body resides within the patient. A first balloon can be located on an exterior surface of the cannula body and the balloon can be deployed within the vasculature whereby space may be provided between a vessel wall and the cannula body. A cannula body can have an aperture formed therein in fluid communication with a lumen. A sleeve can be carried by the cannula and can be configured to be moveable relative to the aperture to selectively cover and uncover the aperture as desired.

    摘要: An over-the-wire heat exchange catheter includes a heat transfer extension having at least one supply lumen and at least one return lumen for circulating heat exchange fluid within the catheter. The catheter has a distal tip and valve attached to the distal tip. The valve automatically seals the distal tip around a guidewire or a mandrel to seal the heat transfer extension and inhibit escape of the heat transfer fluid from the heat transfer extension.
