Ureteral and Bladder Catheters and Methods of Inducing Negative Pressure to Increase Renal Perfusion
Ureteral catheters and assemblies are provided including: a drainage lumen including 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 ureter and/or kidney, the distal portion including a coiled retention portion including at least a first coil having a first diameter and a second coil having a second diameter, the first diameter being less than the second diameter; or wherein the retention portion extends radially outwardly from a portion of the distal end of the drainage lumen portion, the retention portion including a proximal end having a first diameter, a distal end having a second diameter, and a wall and/or surface extending therebetween, the retention portion having a second diameter is greater than the first diameter when deployed; or wherein the retention portion includes a plurality of drainage tubes.
SYSTEMS AND METHODS FOR NASAL IRRIGATION
Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The saline solution source bottle is disposed relative to the device to provide gravitational inducement of saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from an effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of a user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.
Nasal suction instrument with interchangeable tip insert
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.

ASSEMBLIES AND ASSOCIATED METHODS FOR RE-CIRCULATION OF BODY FLUIDS INCLUDING THERAPEUTIC FILTRATION OR CONDITIONING
Body fluid management systems and associated methods for withdrawal and subsequent re-infusion of body fluids, such as cerebrospinal fluid, can be used for therapeutic and/or diagnostic purposes.
System and device for irrigating and cleaning nasal cavities
A system for irrigating and cleaning nasal cavities is provided. In some embodiments, the system includes a stand configured to hold an aqueous solution container. A primary incoming tube leading to a face mask device configured to be worn by a user. In one embodiment, the solution is gravity fed directed through the primary incoming tube into at least one port of the face mask device. A drain line leads from the face mask device to a collection container.
AUTOMATED CATHETER AND CHEST TUBE DEVICES AND RELATED SYSTEMS
A smart fluid discharge monitoring device can have a housing; a frame within the housing; a cartridge positioned within an upper shell of the housing, the cartridge having a window, through which a discharge fluid can flow; a door removably attached to the housing, the door delimiting an interior region of the housing below the upper shell; a tube connected to the cartridge; a plurality of tanks removably secured within the interior region, the tanks receiving the discharge fluid from the cartridge. The smart fluid discharge monitoring device can detect one or more optical characteristics of the discharge fluid through the window as the discharge fluid flows through the cartridge. The smart fluid discharge monitoring device can be a smart catheter or a smart chest tube.
Pump, system and methods of inducing negative pressure to increase renal perfusion
A pump for inducing negative pressure in the ureter and/or kidney is provided. The pump is configured to be in communication with at least one lumen of at least one ureteral catheter and to draw fluid from the ureter and/or kidney into the at least one lumen of the at least one ureteral catheter for removal of the fluid from the ureter and/or kidney. The pump is configured to induce negative pressure ranging from about 0.1 mmHg to about 50 mmHg gauge pressure proximate to the pump inlet, and the pump is configured to have an accuracy of about 10 mmHg or less proximate to the pump inlet.
HEART SUPPORT AND MASSAGE MACHINE
A heart support apparatus includes a heart wrap having a shape configured to conform with a heart of a patient. The heart wrap includes four inflatable compartments, each inflatable compartment is configured to cover one of a pair of atriums and a pair of ventricles. The apparatus includes a negative charge pad configured to deliver an electrical stimulus to the heart and a positive charge pad configured to receive the electrical stimulus. The negative and the positive charge pads are connected to a power source through negative and positive lead cables, respectively. An external device with four piston pumps is used to circulate fluids to the inflatable compartments. A first suction tube and a second suction tube remove a first fluid and a second fluid, respectively, from the heart wrap. A controller with program instructions controls the piston pumps.
CHEST DRAIN CONNECTOR
A breakaway chest drain connector, which includes a first part having an inlet for connecting to an upstream portion of a chest drain tube, a one-way valve and a first flange surrounding the one-way valve; and a second part having an outlet for connecting to a downstream portion of the chest tube, a second flange and a hollow protrusion, the second flange surrounding the hollow protrusion. The second part is connectable to the first part by securing the first flange to the second flange such that the hollow protrusion passes through the one-way valve to form an uninterrupted fluid flow passage from the inlet through the hollow protrusion and the outlet along a longitudinal axis of the connector. The first and second flanges are separable by applying a longitudinal separation force above a defined threshold separation force.
