摘要： An expandable venous valve having a support structure that is configured to enlarge the area adjacent to the valve structure such that the flow patterns of retrograde flow are modified in a way that facilitates the flushing of the pockets at the base of the valve area to prevent stagnation of bodily fluid, which in the venous system, can lead to thrombus formation. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame sections or the support frame can comprise an expanded-diameter intermediate or proximal section that forms an artificial sinus adjacent the valve structure.

摘要： Systems and methods are provided for automatically adjusting the operational parameters of a blood separation procedure. A blood separation device has an inlet for passing fluid thereinto and an outlet for removing fluid therefrom. A pump system is provided for moving fluid into and out of the device. In use, blood is conveyed into the device, where platelets are separated from at least a portion of the blood. A controller determines the amount of platelets in the device. Based at least in part on the amount of platelets in the device, corrective action is taken to avoid platelet aggregation in the device. The corrective action may be conveying an elevated amount of anticoagulant into the blood and/or the device and may be initiated when the determined amount of platelets approaches, meets, or exceeds a threshold predicted likelihood of platelet aggregation.

摘要： Systems and methods are provided for performing a medical procedure with respect to a subject. A data storage location of the system is pre-programmed with a plurality of subject data entries, each having subject-specific information associated with it. A user interface receives an identity input from a subject, which corresponds to the identity of the subject. A controller is associated with the database and the user interface, and is programmed to compare the identity input to the subject data entries. If the identity input corresponds to the subject-specific information of a subject data entry, the controller commands a treatment device to perform a medical procedure with respect to the subject. Otherwise, if the identity input does not correspond to the subject-specific information of any of the subject data entries, the controller generates an error signal which prevents the performance of the medical procedure with respect to the subject.

摘要： Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. A medical device includes a support frame having struts and a weakened frame portion, and a remodelable material tensionably attached to the support frame. The weakened frame portion has a first configuration in which the support frame has a first outward radial force and a second configuration in which the support frame has a second, lesser outward radial force. The remodelable material restricts expansion of the frame from a radially compressed configuration to a radially expanded configuration when the weakened frame portion is in the first configuration. The remodelable material can form one or more valve leaflets adapted to regulate fluid flow in a body vessel, such as a vein.

摘要： Certain examples provide systems, methods, and apparatus to provide information regarding blood donation. Certain examples include a method for providing blood collection information to a donor. The method includes displaying a graphical representation of a donor's donation progress toward a goal for blood component collection to a donor via an executable application icon on a mobile device. The graphical representation is to provide a visual indication of the donor's donation progress toward a goal. The donor's donation progress toward the goal is based on data from a donation facility provided to the mobile device and is displayed via the graphical representation without the donor executing the application. The method includes facilitating access to additional blood donation information for the donor by executing the application via the graphical representation on the mobile device. The method includes facilitating donor action with respect to the blood donation information via the mobile device.

摘要： Medical device delivery systems and associated methods are provided. Delivery systems according to the invention include an elongated tubular member and a body member, such as a dilator, disposed therein. An intraluminal medical device is disposed on the dilator and within the tubular member prior to deployment. The delivery system includes a means for separating two or more portions of the distal end of the tubular member that aids in deploying the intraluminal medical device from the delivery system by separating two or more portions of the tubular member from each other to facilitate release of the intraluminal medical device from the body member. Various structures can be used for means for separating, including a cutting ring, activateable material on the tubular member, or other suitable structure. The provided devices and methods reduce friction occuring from relative movement between the sheath and dilator during deployment.

摘要： Medical devices for implantation within a body vessel can include a remodelable material, such as an extracellular matrix material, positioned within a lumen defined by an outer covering material. The covering material is preferably substantially non-remodelable, and can be supported by a radially expandable frame. The medical device can also include a valve means positioned within the covering material. The valve means can include one or more valve leaflets formed from the remodelable material, and a separate valve support frame. One or more therapeutic agents can be associated with the remodelable material or the covering material.

摘要： A medical device comprises a support structure and one or more graft members comprising a valve portion and a constraining portion. The support structure has a first, unexpanded configuration and a second, expanded configuration. The constraining portion is adapted to substantially prevent the support structure from achieving the second, expanded configuration. The valve portion is adapted to permit fluid flow through a body vessel in a first direction and substantially prevent fluid flow through the vessel in a second, opposite direction.
