摘要: A valve loading system that uses a valve loader to transfer a valve or other medical device from a storage cartridge into a deployment catheter. The valve or other medical device can be implanted or positioned within a patient using the catheter after the valve or other medical device has been compressed and loaded into the catheter using the valve loader. The process then can be repeated by using the valve loading system to load or introduce another valve or other medical device into the catheter. The valve loading system includes a loading pin sized to limit contact with the medical device during a loading procedure.

摘要: A one-way valve opening device, comprising a gasket (4) and a plurality of elastic fine fibers (3), wherein one end of each of the plurality of fine fibers (3) is fixed to the gasket (4), and the other end thereof is free; when the pressure on free ends (6) is not lower than that on fixed ends (5), the free ends (6) of the plurality of fine fibers (3) stay in a gathered state, the plurality of fine fibers (3) are in the form of a cone as a whole; and when the pressure on the free ends (6) is lower than that on the fixed ends (5), the free ends (6) of the plurality of fine fibers (3) are dispersed and are in an open state. The one-way valve opening device is placed into an indwelling needle, a thrombus (11) caused during the usage of the indwelling needle can be prevented in a needle hub (9), such that the thrombus (11) is prevented from entering a human body, and serious consequences caused by the entry of the thrombus (11) into the human body are thus reduced. The one-way valve opening device is placed in a bronchus (16) of a lesion area in a human body, such that the movement direction of sputum (19) can be limited, so that the sputum (19) is discharged out of the body, and the intake and output of gas and liquid is not limited, but same can directly reduce the air intake volume in the lung in the lesion area, indirectly improving the ventilation/perfusion blood flow ratio of a normal lung, and also does not affect subsequent treatments such as alveolar lavage.

摘要: A self-expandable stent includes a folded cylindrical sheet wall, which is folded along axes parallel to the longitudinal axis of the sheet of the cylindrical wall creating three or more drop shaped loops having an inner diameter and an end portion where the sheet of the cylindrical wall contacts each other along an contact surface parallel to the longitudinal axis, wherein each of the at least three bending loops are rotated towards the end portion of an adjacent loop, wherein the end portion has a curvature describing a bending diameter. The improvement includes providing a stent within a fold and deploy structure being able to exert sufficient compression ratios as well as sufficient radial outward forces on the vessel wall, once deployed.

摘要: Closure devices that selectively control blood flow between the right atrium and the left atrium of a heart of a patient. The control of blood flow can be based on detected values from a pressure sensor. The closure devices can include a body configured to engage native tissue when the device is deployed across the septal wall. In a first state at least a portion of (an inner surface of) a lumen is closed, preventing blood flow through the closure device. Ina second state, the lumen is open to enable blood flow from the left atrium to the right atrium. A closure element can be selectively adjusted to control the flow of blood through the lumen. A volume of an expandable chamber can be increased or decreased to place the closure device into the first state or the second state.

摘要: According to certain aspects, an implant device comprises an outer member configured to position the implant device within one or more pulmonary vessels. The implant device also comprises an inner member comprising one or more blades configured to modify one or more of forward waves or backward waves within the one or more pulmonary vessels to reduce interference between the forward waves and the backward waves during systole, the one or more blades having a shape or surface that directs a portion of the forward waves to a region of the one or more pulmonary vessels.

摘要: A prosthesis includes a tubular graft, a prosthetic valve component, an inflow stent, an outflow stent, and a plurality of body stents disposed between the inflow and outflow stents. Each stent is a sinusoidal patterned radially-expandable ring having a first set of crowns and a second set of crowns, with the first set of crowns disposed closer to an inflow end of the tubular graft than the second set of crowns. The prosthesis is configured to be resistant to backfolding and/or buckling during deployment thereof.

摘要: A system includes a stent positionable within a coronary vein. The stent includes a valve and a stent body coupled to the valve and arranged to transition between a collapsed state and an expanded state. The system includes an intravascular reperfusion therapy device with a sensor and a catheter with a lumen shaped to receive the stent. The intravascular reperfusion therapy device delivers reperfusion therapy to a myocardium of a heart. The system includes a processor circuit that receives physiological data from the sensor, determines a progression of the reperfusion therapy, controls a configuration of the valve and/or the expansion state of the stent such that back pressure is controlled. With the stent in the expanded state, the stent body contacts a wall of the coronary vein and the valve obstructs blood flow in a first direction to generate the back pressure in an opposite, second direction.

摘要: The present invention provides a modular prosthetic valve device having two or more device modules for percutaneous delivery unassembled at or near the valve implantation site and assembly at least in part using a self-assembly member, and a system and method of folding, delivering and assembling the device. The device modules may include a support structure and a valve module. The valve module has an unassembled, folded delivery configuration, and an unfolded, assembled (via the self-assembly member) working configuration. The valve module may be a single-piece leaflets substructure or a plurality of valve sections. The self-assembly member has a delivery configuration and may be reverted to a preset configuration for valve module assembly. The unassembled valve module may be rolled along its circumferential axis towards its height to a folded diameter equivalent to one rolled leaflet, providing a percutaneous valve device having a smaller delivery diameter than pre-assembled valve devices.
