The present invention relates to method for implanting a medical device for controlling a flow of fluid in a lumen formed by a tissue wall of a patient's urethra. The method is performed by: cutting the skin of the patient, inserting a dissecting tool and dissecting an area of at least one portion of the tissue wall of the urethra, placing an adjustable constriction device in the dissected area in operative engagement with the urethra, placing an operation device configured to operate the adjustable constriction device to control the flow of urine in the urethra in the patient's body, placing a sensor configured to sense a temperature of the medical device in the patient's body, and placing a control unit in the patient's body configured to control the operation device based on information from the sensor.

Disclosed is an artificial heart and lung apparatus (100) that can be connected to a patient (P), and transfers removed blood to a human body via a roller pump (120), the system including: the roller pump (120); a blood removal line (101) which transfers removed blood to the roller pump (120); a first blood transfer line (104) that transfers blood, which is transferred from the roller pump (120), to the human body; a blood removal rate sensor (111) that is provided in the blood removal line (101); and a control unit (140), in which the control unit (140) performs control such that a blood transfer rate of the roller pump (120) is in a specific range with respect to a blood removal rate measured by a blood removal rate sensor (111).

An intra-ventricular pulsatile assist system is provided including an intra-ventricular blood pump including a chamber having a distal portion and a proximal portion opposite the distal portion, the proximal portion and the distal portion defining an axis extending therebetween and the distal portion defining an outlet; a valve at the distal portion of the chamber, the valve including a closed position in which the outlet is sealed and an open position in which the outlet is unsealed; and a control circuit including a processor in communication with the blood pump, the processor having processing circuitry configured to determine a pressure value in the chamber and transition the valve between the closed position and the open position when the pressure value in the chamber deviates from a predetermined threshold value.

A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

A radially compressible cardiac gripper for at least mechanical stimulation of a heart. The cardiac gripper has two gripper arms, wherein at least one of the gripper arms comprises a flexible section configured for movement of the arm having the flexible section.

A cassette integrated system. The cassette integrated system includes a mixing cassette, a balancing cassette, a middle cassette fluidly connected to the mixing cassette and the balancing cassette and at least one pod. The mixing cassette is fluidly connected to the middle cassette by at least one fluid line and the middle cassette is fluidly connected to the balancing cassette by at least one fluid line. The at least one pod is connected to at least two of the cassettes wherein the pod is located in an area between the cassettes.

A method and device are provided for non-blood contact mechanically assisting an injured (e.g., infarcted) ventricle by coupling an inflatable bladder or other volume adjustable device to the injured ventricle and selectively inflating the bladder or increasing the size of the volume in systole to apply force against the injured ventricle and deflating the bladder or reducing the size of the volume in diastole to remove force against the injured ventricle. When no mechanical assistance is being provided to the injured ventricle, the inflatable bladder or volume adjustable device is preferably maintained at a predetermined pressure so as to selectively stiffen the injured tissue and alter ventricular geometry a desired amount. The method is implemented by a mechanical assist device including the volume adjustable device, a coupling means that couples the volume adjustable device to the injured ventricle, a pulsatile device that selectively increases and decreases the volume of the volume adjustable device, and a controller responsive to the pace of the heart and adapted to selectively change the size of the volume adjusting device in different modes of operation.

A device for treating a vascular aneurysm of a human or mammal patient, comprising an implantable member adapted to hold fluid, the implantable member being adapted to be placed against an outside of a blood vessel having the aneurysm, exercise a pressure on the aneurysm to prevent or reduce an expansion of the aneurysm, follow an outer contour of the aneurysm, and provide a pressure that is equal or less than the diastolic blood pressure of the human or mammal patient.

The invention relates to a blade-type check valve for gaseous and liquid media, to be used in medical technologies as well as in waste water technology with at least three triangular blades, grouped in round configuration at the edges of a polygonal bore of a valve ring or housing, with the number of blades corresponding to the number of faces of the bore. At least at one of the three sides, the valve blades feature an integrated joint, which may also consist of fabric, whereas the two other sides of the valve blades form an articulated lock. The valve can be installed in any position and closes automatically, actuated by the backflow respectively return flow of the medium, without external energy.
