    摘要： Devices and methods are disclosed for achieving hemostasis at a wound site following an endovascular procedure. Such wound sealing is necessary generally following a percutaneous procedure where a percutaneous cannula is withdrawn from the vasculature leaving an entry site to the vessel that could bleed if steps are not taken to stop said bleeding. The devices and methods disclosed herein are especially useful in the catheterization laboratory following interventional cardiology or interventional neuroradiology procedures. The devices utilize the introduction sheath that was originally used for the procedure as a guide for the closure. The closure device is inserted through the introduction sheath once any therapeutic or diagnostic devices have been removed. The closure device comprises a two-part sealing material housed in a reservoir system, a mixing chamber, a delivery cannula, exit ports, and a vessel location device. The sealing material generally comprises materials such as albumin and polyethylene glycol, or the like. The sealing device works in conjunction with the already placed sheath to eliminate the step of replacing said sheath, an action that increases procedural time and may contribute to further wound damage and reduced sealing effectiveness.

    摘要： A system is disclosed for cannulating the vena cava of a patient during cardiopulmonary bypass procedures. Such cannulation is necessary for drainage of venous blood from the patient so that it may be oxygenated and pumped back to the patient to perfuse tissues during cardiac surgery and, more specifically, during periods of ischemic cardiac arrest or dysfunction. The device of the present invention not only provides venous drainage for cardiopulmonary bypass, but also performs the function of routing cardioplegic solution through the heart in the retrograde direction. Such cardioplegia provides protection to the heart during periods of ischemic cardiac arrest. This invention replaces a plurality of cannulae currently used for open-heart surgery, thus simplifying the surgical field and improving visibility of the heart. The device allows for the delivery of retrograde cardioplegia to the coronary circulation of both the right and the left side of the heart. The device further includes protection mechanisms to prevent overinflation or excessive pressurization of the right atrium during retrograde delivery of cardioplegia solution.

    摘要： A device for managing urinary incontinence comprises a resilient body that engages the external genitalia and sealingly occludes the urethral meatus. In female embodiments, the body fits between the labia minora and the floor of the vulval vestibule, occluding the meatus. An adhesive on the body provides a sealing engagement with the meatus. In a first female embodiment, the body has a base with an adhesive layer that seats against the vestibule floor. A pair of flexible, lateral flaps engage the labia minora. A layer of super-absorbent material may be situated between the base and the adhesive layer, and/or a layer of scrim material may be so situated. The body may have a longitudinal ridge with a posterior edge having a finger hole to facilitate installation and removal of the device. In a second female embodiment, the body is substantially tubular, with the adhesive on the exterior surface of the body. In a third female embodiment, the body is an elastomeric bladder, filled with a liquid or gel, that conformingly fits between the labia minora and the vestibule floor so as to occlude the meatus. The exterior surface of the bladder is coated with an adhesive to sealingly occlude the meatus. In male embodiments, the device includes a resilient pad with adhesive on one surface. The pad conforms to and adhesively attaches to the penile glans, with the adhesive sealingly occluding the meatus. Securing tabs may be provided to adhere to the glans or the penile shaft.

    摘要： Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, small cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the ventricular myocardium, more specifically at the left ventricular apex, into the aortic root. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. In an exemplary application, the sheath includes a supported proximal end, a supported distal end, and a collapsible center section. Certain configurations of the sheath are capable of being inserted in a first, small cross-sectional configuration, being expanded diametrically to a second, larger cross-sectional configuration, and then being reduced to a diametrically small size for removal.

    摘要： Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, collapsed cross-sectional configuration, subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration, and subsequent removal in a third, collapsed cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the femoral arteries and the iliac arteries into the aorta. The distal end of the sheath is maintained in the first, collapsed cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is then expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. The distal end of the sheath is subsequently reduced to a diametrically small size for removal.
