A multi-lumen catheter, for insertion into and draining a body cavity, that mitigates the risk of obstruction of the drainage ports and drainage lumen of the catheter, reduces the detrimental effects caused by the suction forces of the drainage ports on the body cavity being drained, and reduces the risk of infection of the body cavity being drained by decreasing the residual volume of fluid retained in the body cavity being drained. These advantages are achieved by the novel approach of disposing a perforated filter membrane or a membrane having a relatively large entry port(s) between membrane struts over a segmented retention element and also over the drainage port(s) of the drainage lumen of the catheter thereby creating internal interstitial drainage channels and internal interstitial drainage cavities.

Systems, devices and methods for draining and analyzing bodily fluids are disclosed in which a drainage assembly is configured to prevent negative pressure build-up. The drainage assembly generally includes a catheter which may include a drainage lumen, a reservoir, a venting mechanism in fluid communication with the drainage lumen and a positive pressure lumen, and a controller. The venting mechanism may further include a valve which is configured to maintain a closed position, as well as a vent in fluid communication with the valve, where the venting mechanism is configured to inhibit wetting of the vent from fluid within the drainage lumen

A novel nasogastric tube, that when properly inserted within a person, blocks the esophagus of the person to prevent gastric contents from being aspirated. The tube can be left in place during direct langroscopy and the device can include a preferably inflatable balloon for obstructing the person’s esophagus. This balloon can be preferably provided on a slidable tube that allows for head movement/flexion without movement of the balloon placement. The tube can be a dual or single lumen device. With a duel lumen device, a first lumen can be connected to a suction tubing to suction gastric contents from the distal end of the tube, while the other lumen can open up above the cuff to allow for easier ventilation with a bag valve mask/BVM. A novel endotracheal tube and novel indwelling catheter also incorporating a balloon component are also disclosed.

Example systems, catheters, and methods are disclosed for actively sampling a fluid. An example system includes a pump configured to pump fluid to direct the fluid a dissolved oxygen sensor and the dissolved oxygen sensor configured to output a signal indicative of an amount of dissolved oxygen in the fluid.

A foley catheter stabilizing apparatus includes an attachment strap, a mounting plate, and a catheter stabilizing retainer. The catheter stabilizing retainer that secures the port divider of the catheter includes a channeled holder, an elastic cover, and a male fastening feature. The attachment strap slidably traverses through the mounting plate. A base of the channeled holder is rotatably mounted to the mounting plate as the attachment strap secures the mounting plate and the catheter stabilizing retainer to patient's leg. A proximal end of the elastic cover is terminally connected to a first lateral wall of the channeled holder. The male fastening feature is angularly connected to a second lateral wall of the channeled holder. The elastic cover is stretched across the first lateral wall and the second lateral wall of the channeled holder and removably mounted to the male fastening feature to secure the port divider in place.

Devices used to collect bodily fluids are disclosed. The devices may include a fluid bag and a transformable hanger for mounting the fluid bag to a support structure such as a hospital bed rail. The fluid bag can include a first fluid compartment and a second fluid compartment. The devices may further include a displaceable front cover and a back cover to obscure the bodily fluids from observation.

A cable for use with a pressure monitoring catheter, the catheter including an inflatable balloon forming a fluid chamber for pressure measurement. The cable has a first end operably connectable to the catheter, a second end operably connectable to a monitor providing pressure displays, and a printed circuit. The cable includes one or both of the filter system to enable collection and analysis of data and an adjustment feature to adjust pressure values in response to patient movement.

A catheter comprising an elongated member having a distal end and a proximal end. The proximal end defines a drainage inlet extending from an external wall of the elongated member into the elongated member. The elongated member defines a first lumen that connects the drainage inlet with a drainage outlet defined by the distal end. The catheter also includes an inflatable retention balloon defined by the external wall of the elongated member and located between the drainage inlet and the drainage outlet. The catheter further includes a fluid inlet valve that protrudes from the elongated member and defines a second lumen that extends from the fluid inlet valve through the elongated member and to the inflatable retention balloon. The catheter additionally includes a secondary balloon that protrudes from the elongated member, the elongated member defining a third lumen that extends from the inflatable retention balloon to the secondary balloon.

Disclosed herein are systems, devices, and methods for the removal of objects from the body. The device may be a urethral catheter configured to aspirate kidney stones from the urinary tract through one or more aspiration ports at the distal face or along a lateral side of the catheter. The catheter may include one or more irrigation ports at the distal face or along the lateral side of the catheter for dislodging kidney stones. The device may be steerable. The spatial arrangement of the one or more irrigation ports with respect to the one or more aspiration ports may vary. The device may include an irrigation tube and/or a shield member configured to spatially confine the kidney stones adjacent the catheter. Various temporal patterns of aspiration and irrigation are disclosed for optimizing removal of kidney stones.

An applicator syringe (1) is disclosed containing a sterile solution having a medical active substance, in particular for introducing the solution containing the active substance via a urinary tract and/or bladder catheter into the bladder of a patient. The applicator syringe (1) includes a cylindrical jacket (2), which is closed by a syringe cover (3), which is integrally formed with the jacket (2) and includes an outlet opening (5) and is formed from a cycloolefin copolymer (COC). The applicator syringe (1) furthermore comprises a plunger tip made of an isobutene-isoprene rubber, which is halogenated in particular. The sterile solution containing the medical active substance is arranged in a cavity (6) delimited by the cylindrical jacket (2) having syringe cover (3) and the plunger tip.
