Abstract: Various embodiments provide systems, methods and assemblies for in situ removal of cerumen from hearing devices positioned in the ear canal. One embodiments provides a fitting for in situ cerumen removal comprising a top portion shaped to be removably coupled to a hearing device component surface and a plurality of leg members extending axially from a perimeter of the top portion. The top portion has a plurality of openings and at least one flexible retaining element configured to releasably engage a retaining feature on the hearing device. The leg members are configured to fit over another surface of the hearing device component. The fitting is configured to remove cerumen obstructing a feature on the device component and can be removed from the device component without removing the hearing device from the ear canal. The fitting can also include a removal loop that has a non-deployed state and a deployed state.

Abstract: A removal tool for atraumatically removing a removable fitting from a hearing device inserted deeply in the ear canal comprises a housing adapted to be grasped in the hand and a plurality of flexible members partially positioned in the housing and extending from the housing. The members have an outwardly flared portion at a distal portion of the member. At least one member includes an engagement element positioned at the flared distal portion of the member for engaging a removal element on the fitting. The tool also comprises a mechanism for engaging the engagement element with the removal element for removal of the fitting independent of a radial orientation of the housing with respect to the hearing device.

Abstract: Described here are flush valves for delivering a selected amount of water from a toilet tank into a toilet bowl, particularly collapsible flush valves having substantial durability and resistance to wear and deleterious chemicals. These flush valves have a collapsible member extending from above the surface of the water in the toilet tank to the tank outlet in the normal (closed flush valve) state. Collapsing the flush valve allows water to flow into the toilet bowl through the flush valve until the toilet tank is drained to the level of the collapsed flush valve and buoyancy is restored. Flush valves may be made of a material that does not substantially deteriorate in the presence of halogen-containing toilet disinfectants, and the outer surface (the water contacting surface) of the flush valves may be a single continuous piece.

Abstract: The application relates to an extrusion apparatus which comprises at least one first reservoir connected at a first end to a first opening of a plurality of regulatory modules. The regulatory modules or spinnerets contain tubular passages through which dope material is extrudable. The extrusion apparatus has at least 1,000 of the tubular passages per square metre cross-section.

Abstract: Angled anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors are adapted to produce an angled end-to-side anastomosis at a graft/host vessel junction. A fitting alone, or a fitting in combination with a collar may be used as a connector. Each fitting may be deployed by deflecting its shape to provide clearance for a rear segment that rotates about adjoining hinge section(s) so to fit the connector within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a trailing or heel segment anchors the fitting in place. The angled fitting may include additional side features for interfacing with the host vessel. The collar may include features complimentary to those of a fitting and provisions for securing the graft to the host vessel.
