  • Publication number: 20230296625
    Abstract: A method of determining a likelihood of liver transplant can be performed on a subject that has consumed acetaminophen at an initial time point and has been diagnosed with hepatotoxicity. The amount of CXCL14 in the blood samples to the series of time points can be measured to determine a trend in the amount of the CXCL14 in the blood samples over a time period beginning at the initial time point and continuing through the series of time points. The trend can be: (a) the amount of CXCL14 increases over the time period - the treatment is determined to be a liver transplant; (b) the amount of CXCL14 increases and then becomes substantially constant the treatment is determined to be a liver transplant; or (c) the amount of CXCL14 has a maximum (> 3000) and then decreases - the treatment is determined to exclude a liver transplant.

  • Patent number: 9522268
    Abstract: An implantable electrode arrangement for a cochlear implant system is described. The arrangement includes a flexible intracochlear electrode array having an outer surface with electrode contacts for applying cochlear stimulation signals to target neural tissue within the implanted cochlea. A flexible extracochlear electrode lead is coupled at a lead proximal end to an implanted signal processor that provides the cochlear stimulation signals, and connected at a lead distal end to a proximal end of the electrode array. A lead holder is connected to the lead distal end and has an initial shape. The lead holder is malleable and adapted to be intra-surgically deformed into and retain a new desired shape so as to secure the lead distal end at the electrode opening into the implanted cochlea and decouple post-surgical mechanical strain at the lead distal end from the electrode array.

  • Patent number: 8948884
    Abstract: A novel electrode array is described for ear implant systems such as cochlear implants (CI) and vestibular implants (VI). The electrode array includes an electrode array core made of a flexible polymer material including an elongated helical portion having multiple helical turns. Electrode wires are embedded within the array core for carrying electrical stimulation signals. At a terminal end of each electrode wire, an electrode stimulation contact is exposed through the array core for applying the electrical stimulation signals to adjacent neural tissue. An electrode carrier of resilient material encases the electrode array and has an outer surface with contact openings exposing the stimulation contacts.

  • Patent number: 8831750

The electrode array includes electrode wires for carrying electrical stimulation signals. At a terminal end of each electrode wire is an electrode stimulation contact for applying the electrical stimulation signals to adjacent neural tissue. An electrode carrier of resilient material encases the electrode wires and has an outer surface with a plurality of contact openings exposing the stimulation contacts. Multiple bend control elements are distributed along the length of the electrode array to control bending flexibility of the electrode array as a function of a bend radius threshold to be greater for bending less than the bend radius threshold and lesser for bending greater than the bend radius threshold.
