A bladder catheter is provided. The bladder catheter includes: a proximal portion configured to be positioned in at least a portion of a patient's urethra; and a distal portion configured to be positioned in a patient's bladder, the distal portion including a retention portion, wherein the retention portion includes an inwardly facing side including one or more perforations and an outwardly facing side, and wherein, when negative pressure is applied through the bladder catheter, fluid is drawn into the bladder catheter through the one or more perforations while bladder walls are prevented from appreciably occluding the one or more perforations by contact with the outwardly facing side of the retention portion.

Ureteral catheters are provided including a drainage lumen including a distal portion configured to be positioned in a patient's kidney, renal pelvis and/or in the ureter adjacent to the renal pelvis for receiving fluid from a patient's kidney and a proximal portion for draining the fluid from the distal portion, the distal portion including a coiled retention portion including: at least a first coil having a first diameter; at least a second coil having a second diameter, the first diameter being less than the second diameter, the second coil being closer to an end of the distal portion of the drainage lumen than the first coil; and one or more perforations on a sidewall of the coiled retention portion of the distal portion of the drainage lumen for permitting fluid flow into the drainage lumen, wherein the proximal portion of the drainage lumen is essentially free of or free of perforations.

A suction instrument includes a proximal end, a distal end configured to be positioned within or adjacent to an anatomical passageway of a patient, and a suction lumen extending between the proximal and distal ends. The suction lumen is configured to provide suction at the distal end. A navigation sensor is disposed along a portion of the suction lumen and is operable to generate an electrical signal corresponding to a location of the portion within the patient. A coupling feature is disposed at the proximal end and is configured to releasably couple the proximal end with a body.

An integrated chest evacuation tube that is specifically configured to function as a closed tube when inserted and retained inside of a chest cavity to provide enhanced benefits over the state of the art. The integrated chest evacuation tube generally includes a fluid impermeable membrane fixedly attached to a single flexible hollow tube. The fluid impermeable membrane is interposed between an inlet port and an outlet port or optionally at said outlet port of a chest tube. The membrane is configured to seal the tube's passageway from any transfer of the fluid. The impermeable membrane is adapted to be ruptured by a force other than pressure from said fluid.

An integrated chest evacuation tube that is specifically configured for being a closed system when inserted and retained inside of a chest cavity provides enhanced benefits over the state of the art. The integrated chest evacuation tube generally includes a valve that is made up of a hollow elastomeric housing having a collar at an output end of the housing which provides an aperture into the housing, a valve input end at an input end of the housing, and an elongated slit at the valve input end. The slit is configured to close together in a spring-like manner when in a closed position. The valve is integrated and at least partially inside of a chest evacuation tube that has a tube inlet port and a tube outlet port. The tube inlet port is adapted to drain fluid and/or air from a human chest cavity. With the collar fixedly attached to the chest evacuation tube at essentially the tube outlet port, the elongated slit is adapted to be opened by a hollow tube when the hollow tube is forcibly pushed through the slit from a direction of the collar.

The invention relates to a vacuum container for drainage of fluids or wound secretion, wherein the vacuum container is pre-evacuated, with an inlet opening for connection to a drainage line, wherein at the inlet opening a vacuum indicator is located and that the inlet opening is sealable. The invention further relates to a drainage line for drainage of fluids or wound secretion, wherein the drainage line has a vacuum indicator, wherein the vacuum indicator is designed to indicate a vacuum inside a connected vacuum container. Further the invention relates to a system for drainage of fluids or wound secretion, comprising a vacuum container according to the invention and a drainage line.

Irrigation and/or aspiration devices and methods may be configured to aspirate and irrigate alone, sequentially, or concurrently. The devices and methods may provide a base with a removable head, and adapted for partial or complete separation of the irrigation and aspiration functions. The devices and methods can be configured to aspirate and/or irrigate the nasal and sinus cavities. The devices and methods may be manually and/or automatically controlled. The devices and methods may include removable, and/or replaceable, and/or refillable, and easily cleanable reservoirs for aspirant and irrigant. The device head and/or aspirant reservoir may comprise a diagnostic device, i.e., test device and/or container after use of the devices and methods.

A toilet modified for disposal of dialysis waste includes a base, a bowl, a water supply port, and a dialysis drain port. In the dialysis drain port is a two piece air gap device that establishes a gap between ends of first and second drain tubes of a dialysis machine and a fluid level in the air gap. RO water and effluent from the dialysis machine enter the chamber of the air gap and mix, before being passed along a path from the dialysis drain port to the bowl of the toilet, where it can be dispelled in a sanitary manner in compliant with all pertinent codes and regulations.

Urinary catheter-insertion kits can include a working tray, a storage tray, a protective paperboard, and a urinary catheter assembly, including a urinary catheter and a drainage system. The working tray can be nested on top of the storage tray. The working tray includes preformed sections configured to accommodate components of the urinary catheter-insertion kit. Methods of urinary catheterization include use of the urinary catheter-insertion kits.
