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.

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 drainage tube, which includes a tube body, a side hole, an air bag and an inflatable tube diameter; the tube body includes a head end and a tail end, the head end is in the shape of an elastic curled ring pigtail, and the tail end includes a drainage nozzle and an inflatable tube. The nozzle and the drainage nozzle are connected to the inside of the tube body; the air bag is set on the outer wall of the tube body, the side hole is opened on the tube wall of the tube body and communicated with the inside of the tube body, and the inflatable diameter is set on the tube body On the inner side of the tube wall, the inflation tube diameter communicates with the air bag and the inflation nozzle. The invention is specially aimed at the drainage problem of pericardial effusion, and the head end is in the shape of an elastic curled circular pigtail, which is beneficial to the fixation of the pericardial drainage tube in the patient's body and the drainage of the effusion. With a balloon structure, the space around the pericardial drainage tube can be extended to a certain extent to solve the problem of blockage of the drainage tube. At the same time, it can also play a fixed role. The point-like contact between the catheter balloon and the heart can reduce the stimulation of the catheter itself to the patient's heart. The onset of arrhythmia and the occurrence of pain.
