A portable applicator for uniformly applying insect repellent or sunscreen upon human skin. A jar-like container normally holds the liquid contents. The container is sealed by a circular lid. The lid supports a downwardly-projecting sponge wiper that is saturated with liquid for subsequent topical application. The underside of the lid has a glue area surrounded by a peripheral ring for securing the wiper, and channels for directing fluid. A wringer-saturator, in the form of a foraminous partition, is disposed between the applicator contents and the wiper. When the applicator is closed, the wiper is compressed slightly by contact with the wringer-saturator. As the lid is removed from the container, the wiper will expand slightly, absorbing and holding liquid. When the lid is reattached, the wiper is compressed slightly against the wringer-saturator and liquid is partially expelled. The wiper has a fiberglass fabric covering for preventing dripping and easing topical application.

Disclosed herein are systems and methods relating to an implant device, such as a heart pump. The implant device may comprise an implant, a fastening device, a release device, and a transfer device. The implant may be shaped for implantation in a vascular canal. The fastening device may have a coupling section that is coupled to the implant and is movable between a fastening position, in which the fastening device is configured to fasten the implant in the vascular canal, and a release device, which may be configured to transfer the fastening device to a release position and releases the implant. The transfer device may be coupled to the fastening device and is adapted to cause transfer of the fastening device between the fastening position and the release position in response to an actuation.

The present disclosure relates to an oral retention device and an osmotic pump tablet, preparation method therefor and application thereof. The medicinal tablet is inserted into the oral retention device to form a pharmaceutical device composition. The pharmaceutical device composition is fixed on the matching teeth in the oral cavity to achieve sustained release of the drug within a certain period of time. A high-dose osmotic pump tablet of the present disclosure with the absorption window of active pharmaceutical ingredients limited to the upper gastrointestinal tract has a high drug loading capacity and can achieve a good therapeutic effect.

A tubular support structure for use in an elongate intravascular medical device comprises an elongate tubular body, a patterned frame structure formed within the elongate tubular body, an inner lumen axially disposed within the elongate tubular body, and a first set of floating tabs axially spaced apart along the patterned frame structure. Each of the first set of floating tabs has a cantilevered end affixed to the patterned frame structure and a free end configured for translating relative to the patterned frame structure and then engaging the patterned frame structure as the tubular support structure is laterally deflected in a first bending direction.

An elongate body extending from a proximal end to a distal end includes a core comprising an amorphous metal alloy and includes a sheath that comprises a crystalline metallic material. The sheath surrounds the core.

A nasal flushing catheter, made of silicone latex, thermoplastic elastomer or other soft and elastic material, can be operated by the patients. The catheter has a closed end and an open end on the opposite side. There are multiple side-holes near the closed end. This catheter, when adapted to a connector and further connected to a syringe, can eject multiple strong thin spouts within the nasal cavity and nasopharynx for cleansing mucus and crust. The catheter may contain at least one stylet to improve its controllability. By a given injection rate of 10 cc/sec using a syringe, the average vertical height of spouts can be predicted by the total area of side-holes, the catheter is therefore classified as following: 1. a low pressure catheter, having 3.367 mm.sup.2?4.123 mm.sup.2 of total areas of side-holes to eject 30 to 45 cm spouts; 2. a medium pressure catheter, having 2.381 mm.sup.2?3.367 mm.sup.2 of total area of side-holes to eject 45 to 90 cm spouts and 3. a high pressure catheter, having less than 2.381 mm.sup.2 of total area of side-holes to eject longer than 90 cm spouts.

A method for treating a tip cover for an injection device to reduce the pull out force of the tip cover. The method includes applying a quantity of a first silicone oil and a quantity of a second silicone oil to an inner surface of a tip cover, the inner surface configured to engage an outer surface of a tip of an injection device and treating the silicone oils to form a cross-linked silicone coating on the inner surface of the tip cover.

This invention pertains to the field of medical devices and specifically relates to an atrial shunt device and its manufacturing method, as well as the application of this device in an atrial shunt system. The atrial shunt comprises a middle channel structure with left atrial wall fixing structures and right atrial wall fixing structures on both sides. The left atrial wall fixing structure is a woven network structure formed by weaving threads through a weaving process, and it includes at least two layers of woven layers. By employing a multi-layer woven structure, this invention enhances the waist support compared to traditional single-layer woven structures, reduces the risk of opening blockage caused by excessive intimalization, lowers atrial pressure, improves patient cardiac function, and prolongs patient life.

A system for supplying power transcutaneously to an implantable device implanted within a subject is provided. The system includes an external connector including one of a microneedle array and a microwire holder. The system further includes a power cable electrically coupled to the external connector and configured to supply power to the one of the microneedle array and the microwire holder, and an internal connector configured to be implanted within the subject and electrically coupled to the implantable device, the internal connector including the other of the microneedle array and the microwire holder. The microneedle array includes a plurality of electrically conductive microneedles, the microwire holder includes a plurality of electrical contacts, and the microwire holder is configured to engage the microneedle array such that the plurality of electrically conductive microneedles extend through the skin of the subject and electrically couple to the plurality of electrical contacts.

A contrast delivery system for determining tissue capture of a shunt device includes a catheter including a lumen having a distal end, an exit hole connecting the lumen to an exterior surface of the catheter, and a side opening adjacent to the distal end of the lumen. The contrast delivery system further includes a tube slidably receivable in the lumen and configured to deliver a contrast agent, the tube including a closed distal terminal end, a first distal hole, and a proximal hole. The first distal hole and proximal hole are spaced along a length of the tube, wherein the first distal hole is disposed between the proximal hole and the closed distal terminal end. The tube is configured to slide in the lumen between a plurality of positions.
