An intraluminal system for aspirating biological material from a lumen of a patient includes a disposable intraluminal device having a proximal portion and a distal portion. The system includes a disposable pump configured to aspirate the biological material from the lumen of the patient. The disposable pump is coupled to the proximal portion of the intraluminal device. The disposable pump comprises a pump chassis that houses: an inlet port configured to sealably attach to the proximal portion of the intraluminal device; an outlet port configured to expel the aspirated biological from the pump; and a flow controller configured to adjust a fluid flow through the pump, wherein the pump chassis is sized and shaped to be manually supported by a user.

Drug delivery devices and systems, are provided for delivery of a drug into the upper urinary tract of patients in need thereof. The drug delivery devices (100) may be deployed directly into the renal pelvis via a patient's ureter, bladder, and urethra, and the drug delivery devices can be wholly retained therein for local continuous, controlled release of a drug over an extended period.

Disclosed herein is a method for increasing urine output and/or sodium output from a patient having venous congestion. The method includes (a) administering at least one medicament to a patient, wherein the medicament increases urine output and/or sodium output from the patient; and (b) applying negative pressure to a drainage lumen of a urinary catheter such that flow of urine from a ureter and/or kidney of the patient is transported within the drainage lumen to extract urine from the patient; wherein administering the at least one medicament occurs before, during and/or after applying negative pressure.

A system for retrieving material from a cavity in a patient may include a tube having a proximal end and a distal end, the scope configured to be inserted into the cavity, and a filter assembly disposed between the tube and a vacuum source configured to apply negative pressure through the tube to cause the material to flow through the tube from the distal end to the proximal end, the filter assembly including a filter configured to trap the material in the filter assembly, and allow liquid and gases to pass through the filter assembly.

A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.

A medical device for capturing renal calculi includes an inflatable balloon, an elongated shaft extending through an orifiace defined by the balloon and attached thereto, a basket apparatus deployable via a distal end of the shaft, and a sheath. The basket includes two or more wire loops that capture calculi and have a collapsed configuration when the basket is positioned within the distal end of the shaft. The medical device can be used by dilating a percutaneous tract by inflating the balloon. A sheath can be advanced over the balloon to create an access route. The basket can be utilized without the removal of the balloon. The balloon can be deflated to allow the shaft and basket to be manipulated in the access route. The shaft and basket can be retracted from the access route to retrieve renal calculi.

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.

The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a delivery device including a tube, and an elongate member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the elongate member is configured to move axially relative to the tube and apply suction through the distal end.

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 pyelo-ureteral stent is provided that combines the benefits of a stent having a lumen with the benefits of a lumen-less stent. In one example, the stent may be implanted in a patient for use during and after a pyeloplasty procedure. The provided stent includes a flexible tube having two separate lumens. Each lumen terminates prior to the stent's closed distal end, which enables a lumen-less ureteric limb at the stent's closed distal end. The lumen-less ureteric limb may have a smaller diameter than the rest of the stent, and may be positioned in a patient's ureter to bridge the pyeloplasty repair, thereby providing the benefits of a lumen-less stent. The flexible tube may be formed with at least one perforated coil for the drainage of urine and/or blood. The stent may be removed from the patient without the use of a cystoscopic procedure.
