Abstract: A device for detecting moisture for use with a device for monitoring an access to a patient for an extracorporeal blood treatment apparatus is described. The device for detecting moisture is constituted as a two-dimensionally extending fabric to be placed on the patient's skin, having an electrically conductive structure as a moisture sensor and constituted by non-conductive and conductive warp and weft threads configured to produce in the woven fabric a defined electrically conductive structure through spatial separation of the warp and weft threads. By the use of conductive warp and weft threads, an electrically conductive structure can be constituted having sections running in different directions, thereby creating a moisture sensor exhibiting a particularly high degree of sensitivity. The electrically conductive structure is preferably terminated with a terminating resistor, preferably not a component part but rather part of a connection part of the device, so that production is simplified.

Abstract: A package or container for a catheter having a catheter tube with a proximal end provided with a catheter outlet and a distal opening at a distal end thereof. A gel receptacle is provided with a cavity for holding an amount of a lubricating agent, and the catheter tube extends therethrough. The gel receptacle is configured such that as the catheter is withdrawn from a stored position therein, a leading tip of the catheter is immersed in the lubricating agent, thus automatically coating the leading tip. The gel receptacle may be held within a rigid body or may be a standalone item packaged in a sterile bag solely with the catheter. A side wall of the gel receptacle is deformable so that as the catheter is withdrawn proximally the side wall is collapsed inward to displace the lubricating agent gel and coat an exterior surface of the catheter tube.

Abstract: Provided herein are balloon systems and related methods for the treatment of obesity. The system includes a trans-abdominal gastric cannula and size-varying balloons that, with the assistance of the cannula(s) and anchors, are specially positioned and anchored to the gastric wall. The size-varying balloon may have an annulus that in combination with reliable and precise balloon positioning, minimizes the risk of gastric obstruction during use. A malabsorption sleeve may be positioned in the small intestine to further restrict caloric intake through the small intestine. The specially-configured gastric cannula provides a platform for accessing the gastric environment that facilitates precise handling, manipulation, and placement of balloons, including an annular-shaped balloon, in the gastric environment, including by balloon anchors connecting the balloon wall to the lumen-facing stomach wall.

Abstract: A cerebral catheter device for draining fluid from the brain of a patient is described. The device may be used as part of a ventricular shunt system. The device includes an elongate tube for insertion into the brain of a patient to a vicinity of a desired target. A head is attached to the elongate tube that has a passageway in fluid communication with a lumen of the elongate tube. Formations are provided on the external surface of the head for securing the head in a hole formed in the skull of a patient. The head further includes a first fluid connector portion that is attachable to an associated drainage catheter device. This allows fluid communication to be established between the lumen of the elongate tube and a drainage catheter device via the passageway of the head.

Abstract: A catheter assembly includes a hydrophilic catheter; a wetting fluid for wetting of the catheter; and a receptacle enclosing at least the insertable part of the catheter and the wetting fluid. The wetting fluid is a solution incorporating at least one osmolality-increasing compound, and the total concentration of the osmolality-increasing compound(s) preferably exceeds 600 mOsm/dm3. The wetting fluid could either be arranged in contact with the hydrophilic surface layer of the catheter in the receptacle, for preservation of the hydrophilic surface layer in a wetted state during accommodation in said receptacle and provision of a ready-to-use catheter assembly, or be arranged to keep the wetting fluid separated from the hydrophilic surface layer of the catheter during storage, but to be brought into contact with said hydrophilic surface layer upon activation before an intended use of the catheter.

Abstract: A process of manufacturing a wound dressing filler and/or wound dressing.

Abstract: A urinary catheter is configured to avoid sliding contact between the outer surface of a catheter tube and the urethra wall. A flexible tubular membrane extends through the catheter tube and has a proximal end secured to an anchor outside the urethra as the catheter tube moves into the urethra, pulling the membrane through the proximal end of the tube so it inverts and covers the outer surface of the tube. Alternatively, a catheter tube of flexible material has a proximal end secured to the anchor, and the catheter tube turns inside out as it is inserted, forming a double wall reflected tube with a proximal reflection point. The sterile interior surface of the membrane or tube becomes the external surface facing the urethral wall as the catheter is deployed, and this external surface maintains static contact with the urethral wall as the catheter is advanced or retracted.

Abstract: Systems, devices, and methods include a hand-held instrument with an aspiration conduit extending therethrough and with an aspiration needle arranged to aspirate fluid from a surgical site. A vacuum limiter is associated with the aspiration conduit. The vacuum limiter includes an opening formed in a wall of the aspiration conduit, an actuator disposed in the opening, and a biasing element biasing the actuator to a closed position that prevents passage of fluid through the opening. The biasing element is arranged to permit the actuator to displace from the closed position to a relief position so that fluid passes through the opening when a threshold vacuum is reached within the lumen. The actuator can further displace to an override position that prevents passage of fluid through the opening.
