  • Patent number: 11504528
    Abstract: A transport system for delivery or retrieval of a biostimulator, such as a leadless cardiac pacemaker, is described. The biostimulator transport system includes a docking cap supported by a bearing within a bearing housing. The bearing allows relative rotation between a torque shaft connected to the docking cap and an outer catheter connected to the bearing housing. The bearing housing and the docking cap include respective bearing retainers that constrain the bearing within the bearing housing without a weld attachment. The weldless retainers of the biostimulator transport system provide a robust mechanical securement of the bearing that is not vulnerable to corrosion. Other embodiments are also described and claimed.

  • Patent number: 11510014
    Abstract: Presented herein are techniques that use acoustic scene (environmental) analysis to determine the sound class of sound signals received at a hearing prosthesis and, accordingly, assess the estimated listening difficulty that the acoustic environment presents to a recipient of the hearing prosthesis. This difficulty of the recipient's listening situation can be used to adjust, adapt, or otherwise set the resolution of the electrical stimulation signals delivered to the recipient to evoke perception of the sound signals. In other words, the resolution of the electrical stimulation signals is dynamically adapted based on the present acoustic environment of the hearing prosthesis.

  • Patent number: 11433246
    Abstract: An exemplary stiffening member facilitates insertion of an electrode lead into a cochlea of a patient. The stiffening member includes an elongate body configured to integrate with the electrode lead so as to maintain the electrode lead in a substantially linear configuration in an absence of a flexure force on the body. The stiffening member further includes compression slots distributed along a first side of the body closer to the electrodes than a second side while the body is integrated with the electrode lead. The compression slots are configured to compress, in a presence of the flexure force, so as to bias the body to flex in an inward direction. Additionally, the stiffening member includes strain relief slots distributed along the second side of the body and configured to expand so as to complement the compression slots in biasing the body to flex in the inward direction.
