摘要： A method for modifying a pump of a ventricular assist device includes the step of modifying pressure-flow characteristics of a pump of a ventricular assist device to simulate different pressure-flow characteristics or to make the flow rate of the pump more responsive to changes in the pressure differential of the pump. The step of modifying the pressure-flow characteristics of the pump may includes one or both of the steps of (1) estimating a flow rate of the pump from the speed of an electric motor of the ventricular assist device and from the current or power consumption of the electric motor, wherein the electric motor drives the pump, and (2) adjusting the speed of the electric motor as a function of the estimated flow rate of the pump and a set speed of the electric motor to simulate the different pressure-flow characteristics or to make the flow rate of the pump more responsive to changes in the pressure differential of the pump.

摘要： An apparatus and method to segregate particles suspended in a fluid with an obstacle field in the flow path of the fluid. The particles may be dispersed after an interaction with obstacles in the obstacle field. The obstacle-particle interactions may result in an asymmetrical particle shift or bump in which the particles are differentially dispersed relative to the obstacle and the fluid flow. Individual obstacles having properties that are asymmetrical are arranged creating asymmetrical gaps between adjacent pairs of obstacles to separate particles flowing through the device.

摘要： A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

摘要： A coupling system includes an applicator tool, an anastomotic prosthesis mounted on the applicator tool, and an engagement device. The applicator tool deploys a securement through the prosthesis and tissue which leaves the prosthesis attached to the tissue. The engagement device selectively engages the applicator tool onto the tissue, with the use of suction, in order to facilitate accurate placement of the prosthesis on the tissue and facilitate deployment of the securement into the tissue. The applicator tool and the tissue are able to move together while the engagement device prevents or inhibits relative movement between the applicator tool and the tissue. A method for securing an anastomotic prosthesis to tissue includes applying of suction to engage an applicator tool to the tissue while a securement is deployed out of the applicator tool and into the prosthesis and the tissue.
