Variables of a surgical system are detected or received via one or more sensors to predict an intraocular pressure (IOP) and/or determine an IOP in real time during a surgical procedure. A notification to a surgeon or a target IOP is set and maintained as determined by Static IOP, dynamic IOP, and/or a total IOP combining both static and dynamic IOP of the anterior chamber of a patient's eye. Information collected about various components of the system are displayed on a user interface. The system uses the collected information to calculate the static IOP and/or dynamic IOP of the system, and the total IOP may be function of the static IOP and/or dynamic IOP measurements.

The present invention discloses a device for removing sputum scabs of a respiratory tract, comprising an outer housing. A fluid hole is designed on a removing part at the front end of the outer housing, and the fluid hole is respectively communicated with a liquid pump and an air pump, so that the device can be extended into the lower respiratory tract of the patient during use. Then, the sputum scabs attached to the inner wall of the respiratory tract can be softened and removed by alternately spraying liquid and gas from the fluid hole, and the removed sputum scabs can be sucked out through negative pressure holes, so as to prevent the scabs of the secretions of the lower respiratory tract from blocking the tracheae.

A suction/irrigation medical device comprises a valve body having one or more conduits fluidically coupled thereto and a first channel extending through the valve body. The medical device also comprises a first valve plunger disposed along the first channel and configured to move along an axis to open and close the first channel. The first valve plunger has a first opening to permit a fluid to flow through the first channel. The medical device also comprises a second valve plunger disposed along the first channel and along a second channel to couple the second channel into the first channel when the second valve plunger is in a first position. The second valve plunger has a second opening that has at least one dimension that is greater than a corresponding dimension of the first opening of the first valve plunger.

In some aspects, provided herein are antimicrobial compositions comprising partially esterified polygalacturonic acid and certain fatty acids (e.g., caprylic acid). In some embodiments, the antimicrobial composition may be administered (e.g., topically or orally) to a subject, such as a human patient to treat an infection (e.g., an infection comprising a biofilm). In some aspects, improved catheters are provided.

Disclosed herein are systems, devices, and methods for the removal of objects from the body. The device may be a urethral catheter configured to aspirate kidney stones from the urinary tract through one or more aspiration ports at the distal face or along a lateral side of the catheter. The catheter may include one or more irrigation ports at the distal face or along the lateral side of the catheter for dislodging kidney stones. The device may be steerable. The spatial arrangement of the one or more irrigation ports with respect to the one or more aspiration ports may vary. The device may include an irrigation tube and/or a shield member configured to spatially confine the kidney stones adjacent the catheter. Various temporal patterns of aspiration and irrigation are disclosed for optimizing removal of kidney stones.

A rectal irrigation apparatus for irrigating a patient's rectum with irrigation fluid (also called lavage) and evacuating feces therefrom. The apparatus comprises several components that work together for integrated operation. The spray nozzle is designed to swirl the spray irrigation fluid in a vortex motion to break-up or loosen feces in the rectum. For example, the spray nozzle may contain a spinning auger to create the vortex motion. The fecal waste is suctioned out into a waste container. The apparatus further comprises a control module that integrates the operation of the various components, such as the vortex generator, the water pump, suction pump, or toilet mechanism. This apparatus could be particularly useful in the treatment of fecal impaction.

In one embodiment, a phacoemulsification system includes a phacoemulsification probe configured to be inserted into an eye, an ophthalmic curette, including a handle, a tube having a proximal end connected to a distal end of the handle, and having a distal tip configured to be inserted into the eye, an irrigation channel extending from the proximal end to the distal tip of the tube, and a pressure sensor disposed at the distal tip of the tube, and configured to be inserted into the eye and provide a signal responsively to intraocular pressure inside the eye, and comprising a sensing surface, and an irrigation-aspiration sub-system coupled with the irrigation channel and configured to convey irrigation fluid along the irrigation channel, and wherein the irrigation channel is shaped, and positioned with respect to the pressure sensor, to direct a flow of the irrigation fluid over the sensing surface of the pressure sensor.

A system for adapting a tubular surgical device for grasping by a surgical instrument is provided that has a distal portion, an adaptor positioned proximally and configured to be disposed about or within a lumen of the tubular surgical device, which has an effective durometer to resist crushing by the surgical instrument. In some embodiments, the adaptor is configured with an external diameter greater than the internal diameter of the lumen of the tubular surgical device. In some embodiments, the adaptor is configured with an external diameter less than or equal to the internal diameter of the tubular surgical device.

This application presents methods and devices for continuously cleaning a colon by at least partially filling a segment of the colon with liquid and agitating the fluid to dislodge matter adhering to the colon walls. Methods for automatic maintenance of liquid levels in the colon during continuous cleaning are taught.
