Abstract: A hearing device seal module for use with a hearing device core including a tubular seal carrier defining a lumen configured for passage of the hearing device core and including a resilient seal support region formed from resilient material and configured to receive the hearing device core, a seal carrier support configured to hold at least a portion of the resilient seal support region open during an insertion of the hearing device core, and a first seal secured to a first portion of the seal support region and extending outwardly therefrom.

Abstract: Hearing devices, configured to fit within the ear canal, having a hearing device core defining an exterior surface with a medial end and a medial corner, and including a battery, a microphone and a receiver, at least one seal, defining a seal compliance, carried on the hearing device core, and a medial bumper, defining a medial bumper compliance that is greater than the seal compliance, carried on the hearing device core.

Abstract: This invention relates to a device for insertion of a deep-in-the-canal hearing aid—alternatively designatable as extended wear hearing aid—into an ear canal of an individual user, at a pre-determined insertion depth (d) thereof. The insertion device comprises a customized support comprising an outer profile conforming to the shapes of at least a portion of a conchal cavity and of an ear canal of said individual user; and a guide channel, disposed internal to said outer profile, extending between a lateral entry opening thereof, for loading said hearing aid; and a medial exit opening thereof, for releasing said hearing aid into said ear canal. The present invention also relates to a method of manufacturing an insertion device for inserting a hearing aid deep into an ear canal of an individual hearing aid user, at a pre-determined insertion depth (d) thereof.

Abstract: A hearing device seal module having a tubular seal carrier formed from resilient material, defining a medial-lateral axis and a lumen configured for passage of the hearing device core, and including a seal support region with a first portion defining a first portion perimeter in a plane perpendicular to the medial-lateral axis and a second portion, lateral of the first portion, defining a second portion perimeter in a plane perpendicular to the medial-lateral axis that is less than the first portion perimeter when the seal support region is in an unstressed state, and a first seal secured to the first portion of the seal support region and extending outwardly therefrom.

Abstract: A hearing device sizer apparatus including a medial sizer, with a medial core portion and a medial seal secured to the medial core portion, and a lateral sizer, with a lateral core portion and a lateral seal secured to the lateral core portion, that are configured to be releasably engaged with one another.

Abstract: A saw blade assembly for use with a driver having an oscillatory drive member comprises an elongate sheath and an elongate monolithic blade. The sheath's proximal end is removably mountable on the driver. The sheath has an open interior which receives the blade. The blade's proximal end is pivotably mounted to the sheath's proximal end. The blade's distal cutting end extends out of the sheath's distal end and is transverse to the blade's central longitudinal axis. When cutting bone, the drive member pivots the blade's cutting end back and forth in an arc about a pivot point at the blade's proximal end while the driver holds the sheath stationary to protect surrounding tissues from the motions of the remainder of the blade. The long pivot radius between the proximal pivot point and the distal cutting end contributes to minimizing the angle of engagement of the cutting end to the bone.

Abstract: Methods, systems and devices are provided for facilitating a surgical procedure on a knee, particularly, a revision total knee replacement procedure. Prior femoral and tibial prostheses are removed. A cut end of a distal femur is engaged with a femoral adjustment member, which will typically center itself about an intramedullary rod placed into the femur. The lateral and medial forces exerted by lateral and medial sides of the femoral adjustment member and the cut tibial plateau against each other are measured. The femoral adjustment member is adjusted to apply and/or adjust tension to the lateral collateral ligament and/or the medial collateral ligament based on the measured forces, for example, such that the measured lateral force and the measured medial force are matched. Based on the position of the adjusted femoral member, guided clean-up cuts for placement of a new femoral prostheses are made on the cut end of the distal femur.
