摘要： A device for removing fluid from a first bodily cavity and for directing that fluid into a second bodily cavity while avoiding risks of infection and, in one embodiment, excessive dehydration of the first bodily cavity. The device includes an uptake tube having a proximal end in fluid communication with the first bodily cavity and a distal end in fluid communication with a pump, and an outflow tube having a proximal end in fluid communication with the pump and a distal end in fluid communication with the second bodily cavity. The distal end of the uptake tube may be coupled to a reservoir configured to expand upon ingression of fluid into the reservoir and to contract upon removal of fluid due to a negative pressure provided by the pump.

摘要： An ascites shunt is described in the form of an implantable, anti-reflux, fluid displacement, compression pump-catheter system. The system includes a double chambered multi-micro-orifice ascites collection device, an anti-reflux, anti-backdiffusion tubular compression pump, and an anti-reflux, anti-backdiffusion, non-thrombogenic catheter, all connected in series by flexible tubing. The shunt is used to transfer fluid from the peritoneum to a blood vessel to prevent accumulation of fluid within the peritoneal cavity. The pump and intravascular catheter include check valve tips of particular design to prevent both reflux and diffusion of blood components into the system.

摘要： A method for the transfer of body fluid which accumulates in the peritoneal cavity into the vascular system is disclosed. This accumulation occurs most frequently with patients suffering from cirrhosis of the liver and constitutes a lethal complication. An implant device is disclosed which comprises a plastic chamber and connecting tubing, said chamber containing unique valve structure comprising a flexible diaphragm seated on a shoulder and attached to this diaphragm a connector bar which is attached at its other end to the center plate of a structure composed of several lateral silicone rubber struts which radiate out from the center plate to connect to a circular peripheral ring. The circular peripheral ring is anchored fixedly to the lateral wall of the valve housing by compression between two threaded connectors of plastic also. These rubber struts place pressure constantly on the diaphragm pulling it toward the shoulder which closes the valve. The diaphragm member is thus fixed to the side wall of the valve housing by the elastomeric strut members. The seat of the diaphragm valve is adjustable and hence it can control the fluid pressure required to open the valve.

摘要： An implantable, body-driven shunt pump includes a pump body defining a fluid inlet, a fluid outlet and a fluid chamber therebetween; an inlet valve arranged in the fluid inlet, the inlet valve being a one-way valve arranged such that it is operable to allow fluid flow into the fluid chamber and to prevent fluid flow out of the fluid chamber; and an outlet valve arranged in the fluid outlet, the outlet valve being a one-way valve arranged such that it is operable to allow fluid flow out of the fluid chamber and to prevent fluid flow into the fluid chamber. The pump body includes an expandable and contractible component in a portion of the pump body that defines the fluid chamber such that the fluid chamber changes volume in response to a change in pressure of fluid in the fluid chamber.

摘要： The present invention features devices that can be used to extract ascites and other fluids from the body with a minimally invasive procedure and, if desired, can also be used to flush the cavity (e.g., the abdominal cavity) from which the fluids were removed. The devices also permit characterization of the fluids in that a surgeon or other health care provider can conveniently obtain a sample of the fluids to assess their composition. The amount of fluid removed from a cavity can also be determined. While the present devices and procedures are not limited to those that bring about any particular physiological response, we believe they will help maintain blood flow and prevent the accumulation of toxins and inflammatory cytokines in bodily cavities, such as the abdominal cavity. We may refer to the devices of the invention as MIST, as they allow for minimally invasive suction and treatment.
摘要翻译： 本发明的特征在于可以用微创程序从体内提取腹水和其它流体的装置，并且如果需要的话也可以用来冲洗除去流体的空腔（例如，腹腔）。 该装置还允许表征流体，因为外科医生或其他保健提供者可以方便地获得流体样本以评估其组成。 还可以确定从空腔移除的流体的量。 虽然本发明的装置和程序不限于那些产生任何特定生理反应的装置和程序，但是我们相信它们将有助于维持血液流动并防止毒素和炎性细胞因子在诸如腹腔的体腔中积累。 我们可以将本发明的装置称为MIST，因为它们允许微创的吸入和治疗。

摘要： An apparatus for distributing a liquid in a patient's body comprises an implantable pump adapted to pump the liquid and an implantable valve device adapted to direct the liquid pumped by the pump. A first ceramic valve member of the valve device includes a first plane surface and a second ceramic valve member of the valve device includes a second plane surface facing and touching the first plane surface. The second valve member is displaceable relative to the first valve member between different positions, wherein the valve members include different liquid channels. The valve device is operable to displace the second valve member to hydraulically connect the pump to at least one of the liquid channels in at least one of the positions.
