There is disclosed a medical device adapted to be implanted in the heart of a patient and operable therein i) as a heart valve; or ii) to assist in the functioning of one of the patient's heart valves; or iii) to monitor the functioning of one of the patient's heart valves. The device includes one or more sensors for sensing a physiologically or clinically relevant parameter of a patient. A telemetric communication device telemetrically transmits data related to a parameter sensed by the sensor to a remote device.

A paste including metal or metal alloy particles (which are preferably silver or silver alloy), a dispersant material, and a binder is used to form an electrical, mechanical or thermal interconnect between a device and a substrate. By using nanoscale particles (i.e., those which are less than 500 nm in size and most preferably less than 100 nm in size), the metal or metal alloy particles can be sintered at a low temperature to form a metal or metal alloy layer which is desired to allow good electrical, thermal and mechanical bonding, yet the metal or metal alloy layer can enable usage at a high temperature such as would be desired for SiC, GaN, or diamond (e.g., wide bandgap devices). Furthermore, significant application of pressure to form the densified layers is not required, as would be the case with micrometer sized particles. In addition, the binder can be varied so as to insulate the metal particles until a desired sintering temperature is reached; thereby permitting fast and complete sintering to be achieved.

According to one embodiment, an apparatus for removing enamel from a person's tooth includes a blade portion and a handle portion. The blade portion includes an abrasive surface adapted to remove enamel from the tooth in response to reciprocating movement of the abrasive surface against the enamel of the tooth. The handle portion is coupled to the blade portion, has a substantially solid cross-section, and is adapted to be inserted into a corresponding opening in a driver mechanism that is adapted to drive reciprocating movement of the blade portion to provide the reciprocating movement of the abrasive surface.

Disclosed is an insert apparatus for a mold for manufacturing structural units. The insert apparatus includes a carrier for operatively engaging a portion of the mold, and is in communication with a face or an object having an engagement design portion thereon. The face is in operative communication with the carrier, and the engagement design portion extends into or out of the cavity of the mold. Methods of manufacturing such a structural unit, methods of retrofitting an existing mold for manufacturing such a unit and novel and improved structural units are also disclosed.

A method for forming a device (10) that fits into a person's ear canal, that carries sound from a pipe (B) of a speaker assembly (A) into the person's ear canal, and that blocks environmental noise. A first elastomeric material (14) is molded around an elongated core (16) to form a device body (12) with an outer surface that can seal to a person's ear canal. In one method, the first elastomeric material of the body is a soft foamable material and the core is a previously-formed tube (16) of a stiffer second elastomeric material, with the body bonded to the tube by being molded around it, either in a mold cavity or by extrusion through an extrusion head. In another method, the elastomeric material of the body is a non-foam, and the core (96) is a rigid pin that is removed from the earplug body after the earplug body has at least partially solidified.
