Provided is a ureteral stent comprising certain amount of ethylene-vinyl acetate polymer and a certain amount of an additive selected from barium sulfate, bismuth subcarbonate, bismuth oxychloride, a polyolefin elastomer, a thermoplastics elastomer, and a mixture thereof. The provided stent may have multiple layers such as inner layer and outer layer with each layer having different elastic modulus. Also provided is a method of making the aforementioned ureteral stent and a method of using the ureteral stent in treating kidney or bladder related diseases.

A suture anchor for tissue repair that has a proximal section and a main section where the proximal and main sections are formed of different materials. The proximal section is formed of a material that promotes in-growth from the surrounding tissue.

Disclosed is a high anticoagulation ECMO and extracorporeal circulation consumable, which include the following preparation methods: S1, aminating the surface of ECMO blood circulation device and extracorporeal circulation consumables; S2, activating heparin groups; S3, heparinizing the ECMO blood circulation device and extracorporeal circulation consumables; S4, modification of enhancer. The application can produce a novel high anticoagulation extracorporeal circulation tube with low price and high biocompatibility, which expands the application in clinic.

A chamber providing controlled amounts of IR and visible light within an internal space sized to seat at least one human being. The chamber includes at least one heater configured to emit FIR energy, at least one heater configured to emit NIR energy, and at least one heater configured to emit at least MIR energy. The chamber includes at least one light emitting source configured to emit a selected wavelength of visible light, and a control panel configured to control the amount and duration of FIR, MIR, NIR and visible light within the chamber.

A staple cartridge comprising staples that are lubricated before they are loaded into the staple cartridge and after they have been loaded into the staple cartridge is disclosed.

An air-permeable guard adapted to attach to a covering, the air permeable guard comprising a plurality of layers attached together to create one or more compartments. The guard further comprises at least one agent stored in the one or more compartments wherein the at least one agent may be a counteracting agent, a masking agent or a disinfectant agent. The masking agent may be coffee, oil and self encapsulated oil beadlet. The counteracting agent may be activated charcoal, sodium bicarbonate, zeolite, diatomaceous earth, silica gel and bentonite clay. The disinfectant agent may be a water based coating containing a cationic siloxane. In another embodiment of the invention the compartments may store the agents in a portion of the guard that is adapted to come in contact with the wearer's nostrils.

A non-pyrogenic preparation containing nanoparticles synthesized by magnetotactic bacteria for medical or cosmetic applications. The nanoparticles are constituted by a crystallized mineral central part including predominantly an iron oxide, as well as a surrounding coating without material from the magnetotactic bacteria.

A quartz glass container is shown and described herein. The quartz glass container exhibits a low concentration of surface defects on an inner surface of the container. In aspects hereof, the container may have a surface defect density of 50 or fewer surface defects per square centimeter within a 1 cm band centered 1 cm from the base of the container.

A syringe is to be obtained by using PTFE for a gasket main body that makes a direct contact with an injection solution and using a slidable silicone rubber at a portion that does not make contact with the injection solution. A syringe A includes a syringe barrel 1, a gasket 10 press-fitted within the syringe barrel 1, and a plunger rod 5 mounted in the gasket 10. In the gasket 10, a concaved groove 18 is formed over the whole circumference of a slide-contact surface 11 of a main body portion 26 that is formed of a rigid plastic having a drug solution-resistant property against a drug solution 30 to be loaded in the syringe barrel 1 and that is configured to slidingly contact an inner circumferential surface 2 of the syringe barrel 1. In a slide-contact ring 19 that is to be fitted in the concaved groove 18 and that is configured to slidingly contact the syringe barrel inner circumference surface 2, a silicone oil and a spherical ultrahigh molecular weight fine powder are added to a silicone rubber base material 19c.

A dissolvable composition is disclosed. The composition includes a first material (e.g., an anode), a second material (e.g., a cathode), and a third material (electrolytic material). The third material is reactive with water to form an electrolyte. The first material and the second material are electrochemically different such that the first material and the second material are capable of galvanic reaction in the presence of water and electrolytes. Also disclosed are tools or other apparatus made from the composition, as well as processes, systems, and apparatus for making and using such compositions, tools, and other apparatus.
