The system includes a laser configured for lithotripsy procedure, a lithotripsy irrigation system, and a temperature sensor configured to provide input to enable control of a flow of the lithotripsy irrigation system in response to a change in temperature from the operation of the laser.

An stent delivery system may include a delivery device and a tubular body having a lumen sized to slidably fit about an outer diameter of the delivery device and a drainage stent having an anchoring mechanism, wherein the delivery device includes a constraining member configured to engage an external portion of the tubular body at the proximal end of the delivery device. A method of delivering a stent may include inserting a tubular body into the port of an endoscope, inserting a stent delivery device and a stent having an anchoring mechanism into the tubular body, wherein the delivery device includes a constraining member configured to engage and retain the tubular body at the proximal end of the delivery device, advancing the drainage stent distally through the tubular body, sliding the tubular body proximally, and engaging an external portion of the tubular body with the constraining member.

Methods, systems, and apparatuses for integrating medical device data are disclosed. In an example embodiment, a processor receives infusion therapy progress data, receives renal failure therapy progress data, and displays derivative data types. Each of the derivative data types includes at least one infusion parameter, at least renal failure therapy parameter, and at least one of the mathematical operation. The example data processor receives a selection of one of the derivative data types, and calculates derivative data by applying the at least one mathematical operation, as specified by the derivative data type, to infusion therapy progress data that relates to the at least one infusion parameter, as specified by the derivative data type, and renal failure therapy progress data that relates to the at least one renal failure therapy parameter, as specified by the derivative data type. The processor also displays the derivative data.

The subject matter described herein includes a kidney stone suction tube device and related methods of use. According to one example, the disclosed subject matter includes a suction tube device comprising a flexible tubing element comprising a modified suction tube portion characterized as having U-shaped hollow lumen channel and an intra-renal portion characterized as having circular shaped lumen channel. The intra-renal portion of the suction tube device further includes a collection cylinder section configured for storing kidney stone fragments. In addition, the connection of the modified suction tube portion and the collection cylinder section includes a mesh filter element configured to prevent admittance of kidney stones into the modified suction tube portion of the flexible tubing element.

A disposable device for treating a condition of a ureter or kidney having a cylindrical body about 1-2 mm in diameter by about 5 to 10 mm in length and having a top and bottom end. The body is made of absorbent material that expands upon contact with pharmaceutical agent and bodily fluids and includes a string connected to the bottom end of the body for removing the device. The device can be used to treat a condition of the ureter or kidney by inserting into the ureter or kidney, delivering a pharmaceutical agent, and removing the device after it has been impregnated with fluid. The device can be included in a kit with an insertion device and/or appropriate pharmaceutical agents.

Methods, systems, and apparatuses for integrating medical device data are disclosed. In an example embodiment, a processor receives infusion therapy progress data that is generated by an infusion pump and renal failure therapy progress data that is generated by a renal failure therapy machine. The processor also receives physiological data that generated by at least one physiological sensor. The processor determines fluid balance data based on a difference between the infusion therapy progress data and the renal failure therapy progress data. The processor displays the fluid balance data in conjunction with hemodynamic information from the physiological data.

Systems and methods for controlling an irrigation flow rate during a lithotripsy procedure are provided. The system includes a laser configured for lithotripsy procedure, a lithotripsy irrigation system, and a temperature sensor configured to provide input to enable control of a flow of the lithotripsy irrigation system in response to a change in temperature from the operation of the laser.

Described herein is a shock wave device for the treatment of vascular occlusions. The shock wave device includes an outer covering and an inner member inner connected at a distal end of the device. First and second conductive wires extend along the length of the device within the volume between the outer covering and the inner member. A conductive emitter band circumscribes the ends of the first and second wires to form a first spark gap between the end of the first wire and the emitter band and a second spark gap between the end of the second wire and the emitter band. When the volume is filled with conductive fluid and a high voltage pulse is applied across the first and second wires, first and second shock waves can be initiated from the first and second spark gaps.

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