An implantable fluid management device, designed to drain excess fluid from a variety of locations in a living host into a second location within the host, such as the bladder of that host. The device may be used to treat ascites, chronic pericardial effusions, normopressure hydrocephalus, hydrocephalus, pulmonary edema, or any fluid collection within the body of a human, or a non-human mammal.

A fluid management system for the treatment of ascites, pleural effusion or pericardial effusion is provided including an implantable device including a pump, control circuitry, battery and transceiver; a charging and communication system configured to periodically charge the battery and communicate with the implantable device to retrieve performance data; and monitoring and control software, suitable for use with conventional personal computers, for configuring and controlling operation of the implantable device and charging and communication system. The implantable device includes a number of features that provide automated movement of fluid to the bladder with reduced risk of clogging, with no patient involvement other than occasional recharging of the battery of the implantable device. The monitoring and control software is available only to the treating physician, such that the physician interacts with the implantable device via the charging and communication system.

A system for noninvasively monitoring cancerous cells within bodily fluid accumulated due to ascites, pleural effusion or pericardial effusion is provided including an implantable pump having control circuitry; a charging and communication system configured to periodically charge and communicate with the implantable pump to retrieve performance data; and monitoring and control software, suitable for use with conventional personal computers, for configuring and controlling operation of the implantable pump and charging and communication system. The implantable pump is configured to move fluid containing cancerous cells from a body cavity to the bladder such that the fluid may be excreted during urination, collected and analyzed with an analysis station to assess progress of the cancer or efficacy of a cancer treatment program.

The invention relates to a plugging stent for a left auricle. The plugging stent comprises a reticular body and a tail connected with the reticular body, wherein the tail is overturned inwards to forma blunt shape, so that the contact area between the tail and the left auricle is enlarged, the situation that left auricle walls and internal tissue are damaged by the tail end of the stent in the transplanting process and after transplanting is avoided, the damage of the surgery to the patient is reduced, simultaneously, risks of hydropericardium, perforation and the like can also be avoided, and the safety of the surgery operation is higher; and in addition, the maneuverability of the plugging machine is better, and under the situation that the transplanting position is not ideal, the transplanting position can be adjusted only through propelling the plugging machine, so that the operation difficulty is reduced, and the medical care effect is improved.

A fluid management system for moving bodily fluid accumulated due to ascites, pleural effusion or pericardial effusion is provided including an implantable pump coupled to an inflow catheter, an outflow catheter, and optionally an anti-clog catheter. The fluid management system facilitates removal of fluid from a body region, such as the peritoneum, pleural cavity or pericardial sac, where drainage is desired to another body region, such as the urinary bladder or the peritoneal cavity. The system includes clog resistant mechanisms such as clog resistant catheters and / or programmed routines for cycling fluid through inlet catheters in predetermined time intervals and / or responsive to sensed conditions to minimize the risk that inlet catheters become clogged due to, for example, tissue ingrowth and / or solid objects within accumulated fluid.

A method of using fluid aspirates as vehicles for drug delivery by collecting a fluid aspirate such as synovial joint effusion, pleural effusion, pericardial effusion, or ascites from a patient and centrifuging the fluid aspirate to provide a supernatant and a sedimented material. The sedimented material can optionally be further purified. One or more factors such as cytokines, bone morphogenetic proteins (BMPs), pharmaceutical drugs and gene vectors are added to the sedimented material or supernatant, optionally also including a biologically compatible medium such as a bioabsorbable sponge, so as to provide a vehicle for the one or more factors for reintroducion into the patient.

The invention provides a pericardial effusion positioning and exporting mechanism, which includes a fixed seat, an inner column is fixedly connected to the inside of the outer cylinder, a base is fixedly connected to the left end of the inner column, and a slider 1 and a slider 2 are movably sleeved on the outer side of the inner column. , the inside of the outer cylinder is movably connected with evenly distributed positioning blocks, the left side of the positioning block is movably plugged with a telescopic seat, the left side of the telescopic seat is fixedly connected with a suction cup, and the inside of the telescopic seat is movably plugged with a platen. The pull plate drives the slider 2 and the slider 1 to move to the leftmost one after another. The slider 2 drives the block 2 to extend outward through the connecting rod, drives the tooth plate to move outward through the gear 2 and the rack section on the base, and drives the gear plate to move outward through the adjustment plate. Squeeze the telescopic seat and move it to the left, so that the suction cup is adsorbed on the patient's skin. Similarly, the suction cup on block 1 is tightly adsorbed on the patient's skin. Therefore, the base is fixed on the patient's body through the suction cup, thereby strengthening the patient's body. Positioning stability of the puncture needle.
