A filtering device for removing particles from a bodily fluid of a patient is disclosed. The device is implantable in the patient's body and comprises a tube forming a main fluid passageway for bodily fluid, through which the bodily fluid passes when the tube is implanted, wherein the tube is sized and adapted to be fluidly connected to the bodily fluid. The device further comprises a filter connected to the tube, and a filter cleaning device for cleaning the filter.

The invention relates to an intravascular blood pump. The blood pump comprises a pump section having a proximal portion with a blood flow inlet and a distal portion with a blood flow outlet and an impeller for causing blood to flow into the blood flow inlet and towards the blood flow outlet. The blood pump further comprises at least one filter connected to the proximal portion of the pump section and arranged with respect to the blood flow inlet so as to filter the blood before it enters the blood flow inlet. The filter may comprise an expandable mesh structure made of a shape-memory material.

A method and apparatus for injecting saline into an open cavity of a patient's body, and, alternatively, vacuuming fluids from said cavity during laparoscopic surgery that provides constant feed and amplified pressure to provide a steady fluid output, in a disposable, single use handheld surgical device.

The device presented is designed to cause, in a mode of operation referred to as “normal” mode, a fluid to flow along this fluid path successively through the first cavity, the filter, the second cavity then the flow restrictor. The device is also designed to cause, in a mode of operation referred to as “purge” mode, a fluid to flow along this same fluid path through the filter but in the opposite direction to the normal flow of the fluid (in the normal mode of operation). Thanks to the “purge” mode, the fluid will detach impurities that have become trapped on the filter in order to clean same.

A medical device includes a first valve and a second valve. The first valve includes a manifold having a first opening, a second opening, and a third opening, and an element movable within the manifold and spring-biased to close the first opening. When biased to close the first opening, air flows from the second opening to the third opening. The second valve is configured to provide a flow of pressurized gas to the first valve to move the element to close the third opening. The first valve and the second valve are configured, upon moving the element to close the third opening, to interrupt the flow of air from the second opening to the third opening and to allow the flow of the pressurized gas to exit the second opening.

The present invention relates to a method of implanting a blood clot removal device in a patient's body, by cutting the skin of the patient's body, dissecting an area of the patient's vascular system, placing the blot clot removal device at the dissected area, and connecting a blood flow passageway of the blood clot removal device to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway.

A method and apparatus for injecting a saline solution into an open cavity of a patient's body, and, alternatively, vacuuming fluids from the open cavity during laparoscopic surgery that provides constant feed and amplified pressure to provide a steady fluid output, in a disposable, single use handheld surgical device.

The invention relates to a system, and the associated method for using said system, for treating haemorrhagic fluid previously taken from a patient for the purpose of autotransfusion, comprising a unit for treating (100) haemorrhagic fluid, said treatment unit (100) comprising: a filtration device (110) for tangential filtration comprising a filtration membrane (113) arranged in a housing (114) so as to separate an intake chamber (111) from a discharge chamber (112), the intake chamber (111) and the discharge chamber (112) each having an inlet (111a; 112a) and an outlet (111b; 112b) for fluids; a treatment pouch (140) having an inlet (140a) and an outlet (140b) fluidically connected by a recirculation line (150) to the outlet (111b) and to the inlet (111a) of the intake chamber (111) of the filtration device (110), respectively, allowing haemorrhagic fluid to circulate in the recirculation line (150) in a direction going from the outlet (140b) of the treatment pouch (140) to the inlet (140a) of the treatment pouch (140) through the intake chamber (111) of the filtration device (110); a cleaning line (180) fluidically connected to the inlet (112a) of the discharge chamber (112) of the filtration device (110) to convey cleaning fluid into said discharge chamber (112); and a first flow regulation member (181) arranged to regulate the flow in the cleaning line (180) and a second flow regulation member (131) arranged to regulate the flow in a discharge line (130) fluidically connected to the outlet (112b) of the discharge chamber (112) of the filtration device (110), so as to be able to control the pressure of cleaning fluid in the discharge chamber (112).
