The present disclosure describes a cost-effective earplug device that delivers minimally distorted sound, offers sound protection, can fit most users, and can protect human hearing from dangerously-high acoustic levels without the cost or inconvenience of a custom earplug.

Implementations of a breast implant may include a shell including a posterior cephalic portion, a posterior caudal portion, an anterior cephalic portion, and an anterior caudal portion. Implementations of the breast implant may also include an anchor coupled within the shell and coupled directly and fixedly to the posterior caudal portion and the anterior caudal portion. The anchor may prevent rotation of the breast implant. The outer surface of the shell may be non-textured.

Provided is an in-vivo indwelling tube having a high flap strength and passing smoothly through a conduit of an endoscope. A tubular member having a proximal side and a distal side; a proximal flap, including a base end on a proximal side and a free end on a distal side, on the proximal side of the tubular member; and a distal flap, including a base end on a distal side and a free end on a proximal side, on the distal side of the tubular member are arranged; where the tubular member includes a distal side first supporting member provided on a distal side of a midpoint between the base end and the free end of the distal flap or a proximal side first supporting member provided on a proximal side of a midpoint between the base end and the free end of the proximal flap.

A breast implant insertion device and method includes a shell having an open and a chamber with an implant arranged in the chamber and a flexible sheath removably connected with the shell. A lubricant is inserted into the shell to coat the implant which is then transferred to the sheath. The sheath is separated from the shell. An opening is formed in a distal end of the sheath and the sheath is squeezed to eject the implant from the sheath for insertion into a patient without any contact of the implant.

According to an aspect, an inflatable implant includes a fluid reservoir configured to hold fluid; an inflatable member; and a pump assembly configured to transfer fluid from the fluid reservoir to the inflatable member, the inflatable member including a body member and a core member, the body member defining a first cavity and a second cavity, the core member being disposed within the first cavity, the second cavity being configured to receive the fluid.

A composition and medical implant made therefrom, the composition including a thick diffusion hardened zone, and preferably further including a ceramic layer. Also provided are orthopedic implants made from the composition, methods of making the composition, and methods of making orthopedic implants from the composition.

An intraocular lens (IOL) having an optical axis extending in an anterior-posterior direction and an equator extending in a plane substantially perpendicular to the optical axis is described. The IOL includes: an elastic anterior face located anterior to the equator; a posterior face located posterior to the equator, wherein the anterior face, the posterior face, or both comprises a poly(dimethylsiloxane) elastomer having a durometer between about 20 Shore A to about 50 Shore A; and a chamber located between the anterior face and the posterior face comprising a silicone oil comprising polysiloxanes comprising diphenyl siloxane and dimethyl siloxane units, the silicone oil having a maximum viscosity of about 800 cSt at 25° C.

A band-shaped medical device (10) for narrowing a body channel (30) of a patient, the device (10) being placeable around the body tissue surrounding the body channel (30), and the device including: a first section (1) composed of a first silicone composition (1a), and a second section (2) composed of a second silicone composition (2a) having a lower Shore A hardness compared to the first silicone composition (1a), and a connecting section (4) which integrally bonds the first section to the second section. The first section and the second section having a first locking part (11) and a second locking part (12), respectively, by which the device (10) is closable to form a ring which encircles a passage opening (16) for the body tissue surrounding the body channel (30), the connecting section (4) consisting of a mixture of the first silicone composition (1a) and the second silicone composition (2a).

A surgical implant (20) comprises a flexible, areal basic structure (22) having a first face and a second face and being provided with pores (26) extending from the first face to the second face. A barrier layer (24) having a first face and a second face is placed, with its second face, at the first face of the basic structure (2) and attached to the basic structure (22). The barrier layer (24) is deformed into at least part of the pores (26) where it forms, in a respective pore (10), a barrier region (28).

A sound attenuation system can include a first end that can include a shaft and a flange, the flange can be coupled to the shaft, and a second end that can include a filter stem and a cap. The filter stem can have a hole. The cap can have a first position in which the cap occludes the hole and can have a second position in which the cap is clear of the hole.
