A system for removing fluid from a urinary tract includes: at least one sensor configured to detect signal(s) representative of bioelectrical impedance and communicate signal(s) representative of the impedance; and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the impedance is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the signal(s) representative of the impedance received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter when the impedance is below the predetermined value and to cease applying negative pressure when the impedance is at or above the predetermined value.

The present invention relates to a filtering device for removing particles from a bodily fluid of a patient, the filtering device being implantable in the patient's body. The device has a tube forming a main fluid passageway for bodily fluid, through which the bodily fluid of the patient passes when the tube is implanted in the patient, a filter connected to the tube and a filter cleaning device for cleaning the filter by moving particles collected by the filter out of the fluid passageway, wherein the filter cleaning device is adapted to replace the first filter in the fluid passageway with a second filter, thereby moving the particles collected by the first filter out of the fluid passageway.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes causing provision of negative pressure, via a flow path, to a wound dressing configured to be positioned over a wound, the flow path configured to fluidically connect the pump system to the wound dressing, measuring a first pressure value in the flow path at a first time, measuring a second pressure value in the flow path at a second time, calculating a first rate of pressure change using the first and second pressure values, and in response to determining that the calculated first rate of pressure change satisfies a threshold rate of change, providing an indication that the wound dressing is full, wherein the method is performed under control of a controller of the pump system.

A disposable thrombectomy maceration and aspiration system for macerating and aspirating thrombus or other obstructive material in a lumen of a vascular graft or vessel. The system includes three major components: a disposable integrated aspiration pump and fluid collection device for generating aspiration vacuum pressure and collecting macerated particulate, a disposable integrated thrombectomy and aspiration apparatus removably coupled to the device configured to macerate the thrombus with a motor powered maceration wire while including an aspiration pathway for aspirating the macerated particulate into the device, and a catheter removably coupled to the apparatus and covering a portion of the maceration wire for insertion into the patient to the thrombus site. The catheter is of sufficient size to allow the macerated particulate to be aspirated from a distal opening through the catheter and apparatus before being deposited into the fluid collection compartment of the device.

A body cavity fluid removal device includes a shaft having a first end, a second end opposite the first end, and an opening at the first end. A handle has a compressible body defining an interior volume. The handle is removably coupleable to the second end of the shaft. The handle is configured for inducing a suction force at the opening of the shaft.

An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

According to some embodiments, a drain line milking apparatus is disclosed. The drain line milking apparatus includes an apparatus body comprising a plurality of side opening for receiving a currently connected drain line to milk fluids away from a user, a removable cover disposed over the apparatus body, a circular disk comprising one or more cam openings, a motor to turn the circular disk and one or more circular cams disposed in the one or more cam openings. The circular disk is disposed within the apparatus body.

A hydraulic pumping system in accordance with embodiments comprises a breast interface operably coupled to an actuatable assembly by means of an actuatable assembly interface. The breast interface comprises a distal membrane coupled to a housing to form a fluid reservoir therebetween. The actuatable assembly interface comprises a proximal membrane. The distal and proximal membranes are fluidly coupled via a tube carrying a driving fluid. The actuatable assembly interface is configured to removably couple to the actuatable assembly, in order to operably couple the actuatable assembly to the breast interface. The actuatable assembly interface comprises a fluid shut off mechanism to reversibly shut off fluid communication between the breast interface and the actuatable assembly interface when the actuatable assembly interface is decoupled from the actuatable assembly.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes applying a drive signal to a pump assembly of the pump system, the drive signal alternating between a positive amplitude and a negative amplitude and the drive signal having an offset, and sampling a pressure within a fluid flow path configured to connect the pump system to a wound dressing configured to be placed over a wound during one or more time intervals. Each of the one or more time intervals can occur when the drive signal is approximately at an amplitude equal to one or more sampling amplitudes.

A method for administering chemotherapy medicament, which comprises providing a closed-system drug administration kit, performing sterile catheterization on a patient by placing at least the distal tip of the catheter into the patient's bladder to drain the bladder, inserting a syringe containing the medicament into a safety adapter at a proximal end of the catheter to prevent leakage during attachment, injecting the medicament into the bladder with the injector through the adapter and the drain lumen without leakage of the medicament from the patient into an environment while assessing a pain level of the patient, removing the syringe and closing the catheter to hold the medicament in the bladder for a given treatment time, and, after the given treatment time, draining the medicament out of the bladder with a medicament pressure reservoir through the catheter and into the medicament pressure reservoir for disposal of the kit.
