  • Publication number: 20200368398
    Abstract: The devices, systems, and methods disclosed herein may be directed to a delivery system including a therapeutic member configured for endoluminal placement via the delivery system into the esophagus of the patient, wherein the therapeutic member comprises a treatment portion comprising a film for controlled release of a chemotherapeutic agent. The film may comprise a control region, a therapeutic region, and a substantially impermeable base region. The film is configured to release the chemotherapeutic agent in a direction away from the substantially impermeable base region. The delivery system is configured to enable a treatment provider to position the treatment portion of the therapeutic member proximate to a treatment site associated with the esophagus of the patient, and the therapeutic member is configured to administer a therapeutically effective dose to the treatment site for a sustained period following endoluminal placement of the therapeutic member.

  • Publication number: 20200322158
    Abstract: This application discloses a method and an apparatus for determining a trust status of a TPM, and a storage medium, and pertains to the field of data security technologies. The method includes: sending, by a verifier (102), an unsealing request to a host (101), so that the host (101) unseals current PCR values in the TPM based on a seal key handle carried in the unsealing request, and sends verification information to the verifier (102) based on the unseal verification key obtained after the unsealing. Therefore, any verifier (102) that establishes an encrypted channel with the host (101) can determine the trust status of the TPM in the host (101) based on a second verification key transmitted on the encrypted channel, and there is no need to pre-deploy a remote attestation server to determine the trust status of the TPM.
