Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured to displace fluid in order to inflate or deflate a medical device, such as a balloon. The devices may further include a crank member for providing a mechanical advantage when pressurizing or otherwise displacing fluid.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

The present invention provides a medical pressurization control device, comprising an outer tube and a threaded push rod inside the outer tube. A movable caliper comprising two arms, a caliper control member connected to the movable caliper, and an operating member connected to the caliper control member are provided in the outer tube; when the operating member moves from a second position to a first position, the operating member drives the caliper control member to move to a locking position, so as to push the two arms of the movable caliper to hold the threaded push rod for locking the threaded push rod; when the operating member moves from the first position to the second position, the operating member drives the caliper control member to move to a release position, so as to push the two arms of the movable caliper to release the threaded push rod for unlocking the threaded push rod.

An occlusion catheter system includes a proximal hub having an inflation connection port and an inflation pathway. An inflation catheter member is connected to the proximal hub and has an inflation lumen. A stiffener member defines a longitudinal axis. The proximal end of the stiffener member is connected to the proximal hub. The stiffener member extends through a portion of the inflation lumen. An occlusion balloon has a proximal balloon end and a distal balloon end. A distal catheter member is positioned substantially on the longitudinal axis and is connected to the distal end of the stiffener member. An atraumatic tip is positioned on a distal end of the distal catheter member. The atraumatic tip has a substantially circular profile in a relaxed configuration. A pressure sensor is connected to the occlusion catheter system distally relative to the occlusion balloon and is connected to a processor by electrical wiring.

Some embodiments provide a soft tissue device, such as a transverse carpal ligament cutting device having one or more balloons that are deflated when the device is in an inactive position and are inflated when the device is in an active position. Other embodiments provide a soft tissue cutting method, such as a method of cutting a transverse carpal ligament that uses a soft tissue cutting device.

An implantable device includes a conduit, an adjustable membrane element coupled to the conduit near the front end of the conduit for controllable coaptation of a body lumen, such as coaptation of a urethra as treatment for urinary incontinence, and a fixation mechanism at or near the front end of the conduit. In various embodiments, the fixation mechanism can anchor the implantable device to the tissue using a movement of a push wire. Optionally, the fixation mechanism can also allow the implantable device to be released from the tissue using another movement of the push wire, to allow for re-positioning or removal of the implantable device.

Catheter devices/systems and methods therefrom are described herein for treating acute kidney injury, especially in the reduction of contrast-induced acute kidney injury. The catheter devices, systems and associated methods may prevent contrast dyes from entering into the kidney and/or facilitate blood flow beyond the kidney by utilization of the catheter devices, systems and associated methods.

A waste management appliance includes a tubular body having a proximal end and a distal end, a cowl fastened to the tubular body at a first circumferential location in a vicinity of the proximal end, a balloon provided within the cowl, and an inflation lumen opening to an interior of the balloon and extending toward the distal end of the tubular body. The cowl extends outside of the tubular body to a second circumferential location spaced from the first circumferential location and is fastened to the tubular body at the second circumferential location. The balloon is inflatable to a desired extent within the cowl by injecting a predetermined amount of fluid into the balloon via the inflation lumen; the cowl restrains inflation of the balloon beyond the desired extent in the event of an injection of more than the predetermined amount of fluid into the balloon.

A liquid injectable pharmaceutical drug product consisting of no less that 99 percent ethanol comprised of no less than 99 percent ethanol active pharmaceutical ingredient with a volume of at least 0.05 mL to be injected into a patient as a method of ablating/lysing cells.

Urinary catheter-insertion kits can include an upper tray fixed to a lower tray and a separator wall positioned over at least a portion of the urinary catheter assembly. The upper tray can include a preformed catheter section configured to accommodate a urinary catheter of a urinary catheter assembly, and a cutout formed through an end portion of the catheter section. A drainage system of the urinary catheter assembly can be disposed in the lower tray, the drainage system including drainage tubing and a drainage receptacle. The drainage tubing can be connected to the urinary catheter through the cutout in the catheter section of the upper tray. Methods of urinary catheterization include use of the urinary catheter-insertion kits.
