A urinary catheter assembly includes a first outer package having a first material, a second inner package contained inside of the first outer package, and an intermediate cavity defined as an area inside the first outer package and outside the second inner package. The first material has a first water vapour transmission rate (WVTR) measured according to ASTM F1249 at 90% relative humidity (RH) and 38° C. between 1 g/(m2.Math.24 h) and 6 g/(m2.Math.24 h). The second inner package has a second material having a second WVTR measured according to test method A at 65% RH and 30° C. below 3 g/(m2.Math.24 h). The second inner package contains a swelling medium and an intermittent urinary catheter with a hydrophilic coating.

The present technology is generally directed to interatrial shunting systems and associated devices and methods. For example, a system configured in accordance with embodiments of the present technology can include a shunting element implantable into a patient at or adjacent a septal wall. The shunting element can have a lumen that fluidly connects a left atrium and a right atrium of the patient to facilitate blood flow therebetween when the shunting element is implanted. In some embodiments, the system further includes a flow control element to selectively control blood flow between the left atrium and the right atrium.

Embodiments disclosed herein are directed to systems and methods of drainage tubes displaying differing mechanical properties along an axial length. These drainage tubes can be provided as integrally formed tubes or as modular systems and can be provided as part of a kit. The differing mechanical properties allows a user to position the tube and to prevent the formation of dependent loops, which allow fluid to pool therein. Proximal portions of the tube can display rigid or malleable properties to maintain a negative incline, or be positioned and remain in position until repositioned. Modular tube kits allow a user to select different mechanical properties along an axial length and modify an overall length of the tube to suit the user's needs.

A modular tunneled catheter is provided that allows lumen length and cuff positioning to be adjusted based on the size of a patient. This catheter should be useful for any patient who would benefit from customized fitting of a catheter to their measurements. Methods of using the modular catheter for hemodialysis, peritoneal dialysis, and fluid drainage, including drainage of plural effusions from the lungs or malignant ascites from the abdomen are also described.

The present invention relates to novel surgical drains and associated methods and systems. Specifically, the present invention includes a surgical drain with at least two ports. A first port drains lymphatic fluid from a subject for collection and analysis. The second port functions to introduce a therapeutic into the subject.

To reduce the suffering of the patient and enable easier removal of excess fluid such as pleural effusion fluid from the chest space, the disclosure provides a catheter for chest drainage intended for removal of excess fluid from a chest space of a living body and to be placed in the living body in such a manner as to extend from an inside of the chest space to an outside of the living body. The catheter includes a passage member formed of a flexible sheet and having a passage through which the excess fluid is to be drained, and an indwelling member formed of an elastic body and provided at a proximal end of the passage member. The indwelling member has an inlet that allows the excess fluid to flow through. The indwelling member includes a retaining portion spreading in a flange shape and being retainable at a chest wall.

Devices and methods are disclosed for managing and/or treating body tissues obstructing a hollow body lumen, including the prostatic lobe tissues obstructing the urethra, for example conditions including benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), benign prostatic obstruction (BPO) and associated lower urinary tract symptoms (LUTS). A prostatic implant deployment and delivery system may have a controlled release mechanism, a handle mechanism and an irrigation system. The controlled release mechanism includes a disengageable connection between a pusher member and the prostatic implant with a control member. The handle mechanism includes a plunger for advancing the pusher member and an actuator for withdrawing the control member. The irrigation system may define two fluid paths.

The devices and methods described herein include an implantable body lumen fluid flow modulator including an upstream flow accelerator separated by a gap from a downstream flow decelerator. The gap is a pathway to entrain additional fluid from a branch lumen(s) into the fluid stream flowing from the upstream flow accelerator to the downstream flow decelerator.

A catheter device and manufacturing process for manufacturing the catheter device, wherein the catheter device has a halo-shaped coiled portion extending away from a perpendicular stem portion through a swan neck portion. Eyelets on the halo coil portion and swan neck portion facilitate flow out of the bladder through the catheter device vertical to the catheter, rather than perpendicularly as is the case with existing catheters. The catheter device is formed by using a straight catheter tube, heating and cooling it within a formed mold to have the halo coil and swan neck, such that it can be straightened using a pusher and stylet, inserted into the body while straightened, and thereafter return to its coiled shape when the stylet is removed.
