A suction stent for introduction into a hollow organ of the human or animal body, preferably into the gastrointestinal tract, in particular the intestine, includes a tubular hollow body which is open in the longitudinal direction and made of biocompatible material. The tubular hollow body has a fixed diameter at least in its central portion; and a porous shapeable material, preferably a sponge material, which is biocompatible and shapeable in the radial direction, the porous shapeable material radially sheathing the tubular hollow body at least in a section of the tubular hollow body. Further, a method is provided for sealing a leakage, especially an anastomosis, of the hollow organ.

Methods and apparatus for guiding medical care based on sensor data from the gastrointestinal tract are described utilizing an apparatus which can be used with enteral feeding. Generally, the apparatus includes an elongated body having a length configured for insertion into a stomach and at least one pair of electrodes located along the length of the elongated body and positionable for placement within the stomach. A controller in electrical communication with the at least one pair of electrodes is included and the control may also be configured to measure a conductivity or impedance between the pair of electrodes and to determine a gastric residual volume of the stomach based on the measured conductivity or impedance.

Devices, systems, and methods herein relate to performing dialysis to manage a chronic condition such as end-stage renal disease. These systems and methods may allow a patient to orally ingest a potable dialysate and excrete the dialysate via the urinary tract. In some variations, a method may include delivering a dialysate via the esophagus of a patient and draining the dialysate into a bladder of the patient. Delivering the dialysate may further comprise delivering the dialysate through the nasopharynx or oropharynx. Delivering the dialysate through the oropharynx may comprise the patient drinking the dialysate.

The embodiments disclosed herein relate to balloon dilation systems. The balloon dilation systems can include a balloon catheter assembly, an elongated member, and a balloon inflation device. The balloon catheter assembly can comprise a balloon that is configured to be expanded to a plurality of discrete diameters at a plurality of discrete pressures.

A multi-purpose balloon catheter includes a catheter having a proximal end portion, a central portion and a non-branching distal end portion, a plurality of lumens associated with the catheter extending from the proximal end portion, and a plurality of inflatable balloons positioned in the central portion and/or the non-branching distal end portion. Each of the plurality of inflatable balloons is communicatively associated with a corresponding one of the plurality of lumens, the plurality of inflatable balloons being selectively inflated or deflated to position and stabilize the catheter in a cavity for delivery of a medical treatment. The catheter can include an extraction point associated with a lumen to remove fluids and materials from the cavity, and a connector associated with a corresponding lumen adapted to selectively receive one or more of a fluid medium or a radioactive isotope provided to a corresponding lumen for delivery of the medical treatment.

Some implementations of the disclosure are directed to a balloon dilator system, including: a hand piece including an attachment mechanism for removably coupling to a proximal end of an endoscope; a hole for inserting a distal end of a balloon catheter including an inflatable balloon; and a hollow tube distally extending from the hand piece, a proximal end of the hollow tube configured to receive the balloon catheter inserted through the hole and advance the balloon catheter such that the distal of the balloon catheter exits a distal end of the hollow tube. The hand piece may include a pump handle that, when actuated, pumps pressurized fluid to inflate the inflatable balloon.

A device for treating esophageal target tissue comprises a catheter, a balloon and a refrigerant delivery device. The catheter has a distal portion and a refrigerant delivery lumen. The balloon is mounted to and the refrigerant delivery device is coupled to the distal portion. The refrigerant delivery device comprises a chamber with the refrigerant delivery lumen opening into the chamber, a refrigerant delivery opening fluidly coupled to the balloon interior, and a distribution passageway fluidly coupling the chamber and the refrigerant delivery opening. A refrigerant is deliverable through the refrigerant delivery lumen, into the chamber, through the distribution passageway, through the refrigerant delivery opening and into the balloon interior so to place the balloon into an expanded, cooled state so that the balloon can press against and cool esophageal target tissue. The medical device may include means for sensing a leak in the balloon.

A novel clinical decision support system (CDS) helps the clinician setup, maintain, and interpret esophageal pressure measurement. The esophageal pressure CDS (Pes CDS) would remind the clinician to do an occlusion test whenever the balloon is first inserted or changes dramatically. It could monitor the occlusion test and provide feedback on the performance and success of the occlusion test. Changes in the patient or monitored data can be tracked by looking for changes in the balloon baseline pressure, changes in the amplitude of the pressure waveform, or changes in the pattern of the Pes waveform. Having information from the ventilator will further increase the ability of the system to determine when Pes is changing unexpectedly.

A catheter (1) resector balloon (8) used in the treatment of any type of endoluminal-endobronchial tumoral or non-tumoral narrowing and occlusions and endovascular obstructions seen in the hollow tubular organs such as the trachea, esophagus, urinary tract, biliary tract, etc. and vessels, characterized in that, it comprises the following; at least one flexible pad section with pressure and proximity sensor and/or pad section without pressure and proximity sensor which provides soft stopping at the final wall section where the catheter (1) resector balloon (8) is applied in a soft, flexible and shock absorber manner at the tip (2) portion, prevents punctures, tears, bursts or vascular damages occurred in the tissues and vessels formed as a region, undesired complications, provides stopping without giving any damage to its location.

A catheter sensor assembly for use in conjunction with electronic catheter guidance systems is provided and includes a catheter and a sensor. The catheter extends in a longitudinal direction and has a proximal end and a distal end that define a lumen therebetween. Further, the catheter is configured for placement within a digestive tract or respiratory tract of a patient. The sensor includes a carbon dioxide sensor, pressure sensor, or both, and can be located in an air sampling chamber connected to the catheter. The sensor can communicate with a processor to deliver carbon dioxide and/or pressure readings to a display device, which can indicate placement of the catheter in the digestive tract or in the respiratory tract. A catheter guidance system and a method for accurately placing a is also provided.
