A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.

A transfer set with integrated disinfectant includes a main body, a cap, and a disinfectant chamber. The main body has a hollow tube shape, a catheter end, and a connecting end that includes mating components. The cap is configured to engage with the mating components. The disinfectant chamber is integrated around an outer circumference of the main body. The catheter end selectively couples to tubing. The disinfectant chamber is located between the catheter end and the mating components. The disinfectant chamber includes a closed end adjacent the catheter end and an open end adjacent the mating components. The disinfectant chamber contains a disinfectant.

The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices and delivery systems for positioning and delivering medical devices with an unsupported structure, for example, within a distant and/or tortuous portion of body lumen. For example, a delivery system may position a supported structure of a medical device within a proximal portion of a body lumen and an unsupported structure of the medical device within a distal portion of the body lumen. Examples include delivery systems within an unsupported structure of a medical device to be delivered, wherein a number of balloons are arranged un-inflated within an unsupported structure, with a distal balloon removably attached to a distal portion of the unsupported structure, and the balloons are inflatable in series to deploy the unsupported structure linearly from a distal end of the delivery system.

Disclosed systems relate to medical devices for delivering fluid. In an example, a device includes a catheter having a distal end and a gasket movably positioned within a lumen of the catheter. The gasket includes a distal end having a first diameter, a proximal end having a second diameter that is greater than the first diameter, and a body connecting the distal end and the proximal end. The device also includes a nozzle positioned on the distal end of the catheter.

A retrograde blood flow occlusion flushing device includes a first catheter, and a second catheter. The second catheter is axially movable with respect to the first catheter. The second catheter has an inflatable balloon connected to an outer circumferential surface of the second catheter at the distal end of the second catheter. The balloon is movable between a collapsed state and an inflated state. The second catheter has a port in the sidewall between the proximal end of the balloon and the distal end of the balloon. The balloon has at least one port proximate the proximal end of the balloon. In the inflated state, fluid is deliverable through the lumen of the second catheter, through the port in the sidewall of the second catheter to inflate the balloon and at least some of the fluid exits the inflated balloon in the proximal direction through the port in the balloon.

A urinary catheter cap includes a main body that includes a urine introduction passage including a connection hole configured to be connected to a urinary catheter and a drain hole for draining urine, a lid portion that has a tubularly formed portion having a first end portion at the drain hole side and a second end portion at an opposite side and opens and closes the drain hole, a partition portion that divides the tubular portion of the lid portion into a plurality of spaces, and a hydrophobic film that is formed such that the hydrophobic film blocks at least two or more of the spaces at the second end portion of the lid portion. The partition portion may include a partitioning plate that is installed between a plurality of locations of an inner circumferential portion of the tubular portion of the lid portion.

A stylet may be used to perform measurements via an indwelling catheter. The stylet can be configured in various ways to selectively occlude the indwelling catheter. Because of this selective occlusion, the indwelling catheter can be used for blood draws, infusions, and other functions even while the stylet remains extended through the indwelling catheter.

A balloon catheter is described having a reinforced, co-axial, duel lumen design. In some embodiments, the balloon catheter includes a purging mechanism designed to purge air from the balloon.
