Abstract:
The present invention discloses a vaginal microbiota collection device and modular preservation unit comprising a means to collect and preserve the vaginal microbiota from an individual, a means to distribute the harvested microbiota, or both. The means to distribute the harvested microbiota comprises a collection apparatus with one or more modular components. The vaginal microbiota is distributed based on need or validation. The collection and preservation of the vaginal microbiota is accomplished by a piston mechanism. The present invention also discloses a method of harvesting vaginal microbiota using the device disclosed herein.
Abstract:
A channel device is disclosed for transporting gas and/or liquid between a control unit and a scope accessory, the channel device comprising a wash line, the wash line comprising: a wash line gas channel; a wash container; a piston; and a wash line wash channel, the wash line gas channel being configured to receive a gas from a wash line gas output of the control unit, the piston being configured to be actuated due to an increase in pressure in the wash line gas channel caused by the received gas to cause a liquid to be expelled from the wash container, the wash line wash channel being configured to transport the expelled liquid to the scope accessory.
Abstract:
A system for performing irrigation of a body cavity includes a reservoir containing an irrigation liquid, a catheter and a controller. The catheter is configured to be at least partially inserted into the body cavity and has a flushing passage, a drain passage and a retention balloon. A waste drain valve is in fluid communication with the drain passage of the catheter and is movable between a closed configuration, where waste is retained within the drain passage, and an open configuration where waste flows through the drain passage. The controller is in fluid communication with the reservoir and the catheter, and has a pump and a valve assembly. The valve assembly is changeable between configurations where, when the pump is actuated, irrigation liquid is pumped from the reservoir to the retention balloon, from the reservoir to the flushing passage of the catheter and from the retention balloon to the reservoir.
Abstract:
Methods and apparatuses for utilizing an integrated, automated aerating device for echogenicity are described. The aeration device can have a pressurized vessel to provide echogenic air bubbles independently of fluid delivered for sonohsyterosalpingography. The aeration device can selectively supply a gas in liquid during ultrasound and radiographic procedures for enhanced visualization of the uterine cavity and fallopian tubes.
Abstract:
An apparatus and method of detecting an interchangeable tip of a handpiece of an ocular surgical system is disclosed. The interchangeable tip of the system includes an irrigation port that receives fluid flowing from an irrigation source and an aspiration port that removes or aspirates fluid and/or materials from the surgical field, in particular a patient's eye, through use of an aspiration source or pump. The method comprises attaching the interchangeable tip to the handpiece, introducing fluid flow into the system and determining the fluid flow rate of fluid flow in the system, determining the pressure of fluid flowing into the interchangeable tip, determining the pressure of fluid flowing out of the interchangeable tip and comparing the flow rate and pressure information to known flow rate and pressure readings of known types of interchangeable tips to determine the type of interchangeable tip being used.
Abstract:
Methods and devices are disclosed herein that allow for infusion and aspiration through a single device. The device can be used to treat a stroke by delivering the device to the site of a blood clot and simultaneously or sequentially infusing a thrombolytic or other drug into the clot and aspirating the dissolving clot from the patient. The methods and devices can advantageously permit more efficient thrombolytic infusion and clot aspiration. Modular systems are also disclosed, as are methods of treating subdural hematoma or other conditions.
Abstract:
Fluid management in surgical procedures. At least some of the illustrative embodiments are methods including: supplying fluid to a surgical site inside a patients body; drawing fluid from the surgical site through a first instrument by a first pump at a first flow rate, the first flow rate during the drawing responsive to expected or actual visibility within the surgical site; and then performing a surgical resection within the surgical site using the first instrument, the performing the surgical resection changes the first flow rate; and adjusting, by a fluid management system after the surgical resection, the first flow rate responsive to the expected or actual visibility within the surgical site.
