An article is described including an article surface and a coating set comprising an optional tie coating or layer, a barrier coating or layer, and a pH protective layer. The respective coatings or layers can be applied by chemical vapor deposition of a polysiloxane or polysilazane precursor in the presence of oxygen. Examples of such an article are a thermoplastic syringe, vial, or blood collection tube with a coated interior portion containing a pharmaceutical preparation or other fluid with a pH of 4 to 8, alternatively 5 to 9. The barrier coating or layer prevents oxygen from penetrating into the thermoplastic syringe, vial, or blood collection tube. The tie coating or layer, if present, and the pH protective coating or layer protect the barrier layer from the contents of the syringe, vial, or blood collection tube.

A pneumatic cross-connect proportional valve provides the capability to calibrate pressure and vacuum sensors in a surgical cassette associated with a surgical console. Calibration of non-invasive pressure and vacuum sensors in a cassette by utilizing a proportional cross-connect to pressurize the lines with set pressure or vacuum the lines with set vacuum and measure the response of respective sensors in the cassette. The use of proportional pressure may be used along with other clearing methods to clear material clogging the aspiration channel pathways and tubing of the surgical system. Utilize the cross-connect functionality to more rapidly pressurize the aspiration line upon detection or prediction of a post occlusion surge, thereby reducing the pressure difference between the surgical field, the eye chamber, and aspiration line which may prevent, for example, a surge of fluid out of the anterior chamber of the eye.

Systems and methods for cleaning body cavities are presented. Some embodiments reduce size of fecal matter pieces within an evacuation conduit. Some comprise devices and methods for purging an evacuation conduit. Some comprise reduced cross-sectional profiles of a cleaning device. Some protect intestinal tissue by preventing exposure to excessively high and low pressures.

A fluid management system includes a pump configured to pump fluid through the system at a fluid flow rate. The system includes a processor including a user interface, the user interface allowing a user to input a set of system operating parameters, the processor being configured to control the pump to maintain a target fluid flow rate based on the set of system operating parameters. The system further includes a scope device coupled to the pump to deliver fluid to a target surgical site, the scope device including an elongated shaft extending from a distal end thereof, the elongated shaft including at least one sensor, the sensor transmitting sensor data relating to target surgical site to the processor. The processor automatically signals to the pump to adjust the fluid flow rate based on the sensor data.

An irrigation system having attachable anti-sliding features that prevent movement of the system along a surface. The irrigation system includes a console having a front panel with an inflow pump and an outflow pump. The front panel extends to a front edge of the console and the front edge is connected to a bottom side of the console. The attachable anti-sliding features include one or more feet attached to the bottom side of the console. Each foot has an L-shaped body having a first end and a second end with a first surface and an opposing second surface both extending between the first end and the second end. A protrusion extends from the second end of the body, forming the L-shape. The one or more feet are attached to the bottom side of the console such that the protrusion extends away from the console.

A method for coordinating the operation of a surgical instrument and a surgical pump to control fluid pressure in an internal anatomy of a patient during a surgical procedure includes: receiving video data captured by an imaging device configured to image the internal anatomy of the patient; automatically determining a presence of a surgical instrument in the internal anatomy of the patient based on the received video data; and in response to determining that the surgical instrument is present in the internal anatomy of the patient, initiating a suction associated with the surgical instrument prior to activation of the surgical instrument.

Systems and methods for cleaning a colon or other portion of an intestine include optional use of sensors to detect conditions of blockage of flow of materials within an evacuation channel used to remove fecal material from the body; and devices and methods for purging such blockages from the evacuation channel.

A pump device for use with an operating table in an operating room. The pump device including: a pump for pumping a rinsing liquid through a pump tube, and a controller configured to determine a height adjustment of the operating table in the operating room and control the pump pressure of the pump based on the detected height adjustment.

In accordance with some configurations, systems and methods for guided removal from an in vivo subject are provided. In some configurations, a method for removing an object is provided. The method comprising, guiding a flexible tube through a passageway of an in vivo subject, wherein the flexible tube comprises at least a first passageway and a second passageway. Positioning a distal end of the first passageway in proximity to the object. Infusing liquid through the second passageway substantially continuously. Removing the object through the first passageway with at least a portion of the liquid while suction is not being provided.

An oral irrigator has a separate high pressure water system and low pressure mouth rinse system to deliver two different fluids to a pick or other accessories. The water system and mouth rinse system are combined in a handle. The pick is connected to the handle. The water system has a blocking valve located in the handle and the mouth rinse system has a hand pump located in the handle. The hand pump sits next to a valve button for closing the blocking valve. When the hand pump is pressed, it presses against the valve button of the blocking valve to shut off the source of high pressure water to the pick. The pressure in the pick drops so that the hand pump can then introduce mouth rinse into the pick. When the hand pump is released, the blocking valve opens up and high pressure water returns to the pick.
