9 results about "Indwelling catheter" patented technology

A dialysis system having motor driven pressure estimation of fluid within a patient line is disclosed. A peritoneal dialysis (“PD”) system includes a fluid pump and a patient line that fluidly couples the fluid pump to an indwelling catheter leading into a patient's peritoneal cavity. The PD system also includes a motor driver that controls a motor of the fluid pump and transmits an output signal that is indicative of a load on the motor. The PD system further includes a machine learning algorithm that associates data related to output signals from motor drivers with known fluid pressures within patient lines. A processor of the PD system transmits an input signal to activate the motor driver, receives the output signal from the motor driver, and estimates a fluid pressure within the patient line by applying the data from the received output signal to the machine learning algorithm.

An open balloon indwelling catheter for drainage from, irrigation to, and retention within a patient's body cavity. The indwelling catheter has a hollow tube catheter member. A double walled balloon having an inner wall and an outer wall is attached to a sidewall of the hollow tube catheter member. The hollow tube catheter member has catheter orifices formed through the sidewall in an area covered by the double walled balloon. Balloon orifices are formed through the double walled balloon for passage of fluid from the body cavity. An inflation passageway is created between the inner and outer walls of the ballon for inflating the double walled balloon. When the double walled balloon is inflated the bodily fluid is transmitted from the body cavity through the balloon orifices and the catheter orifices to a catheter lumen for disposal.

Long-term catheter assemblies (100) are described, each comprising a housing (102) having an interior (104) containing a catheter assembly (108), which may include a catheter tube (110) and a needle (112). The catheter tube (110) of the catheter assembly (108) can be placed in a patient's vein, with or without a guidewire, and the long-term catheter assembly (100) can then be activated to separate into two or more housing components (193, 194) or by opening a gate (340, 606a, 606b) to allow separation of the catheter assembly (108) from the housing (102). A needle shield (140) may be included to cover the needle tip (114) of the needle (112) from needlestick injuries.

A balloon retention catheter or tube is provided that includes a flexible multi-lumen tubular body having a distal tip coaxially mounted to the distal end of the tubular body with an expandable retention balloon secured to the distal tip and distal end. The distal tip and distal end are configured to move axially away from one another when the balloon is in its expanded configuration and held in place in the body and the tubular body is pulled backward away from the distal tip. Such axial movement reconfigures the distal tip and the distal end into a configuration that provides fluid communication between interior space of the balloon and a first lumen to automatically deflate the balloon. The balloon retention catheter or tube can be adapted for use in a urinary bladder to drain fluid from the bladder, or for use in a stomach to supply nutrients to the stomach.

A locking stabilizer for inhibiting movement of an indwelling catheter includes an actuator having an actuator opening for receiving the catheter into the stabilizer, a base having a base opening through which the catheter exits the locking stabilizer, and a torque-actuated gripper between the cover and the base. The torque-actuated gripper exerts exert a variable gripping force on a section of the catheter, the section extending between the base and the cover. The actuator is operable to cause the grip to transition between exerting the gripping force and releasing the gripping force.
