  • Publication number: 20160000602
    Abstract: Embodiments of an implantable device for delivering a therapeutic agent to a patient include a reservoir configured to contain a liquid comprising the therapeutic agent, and a cannula in fluid communication with the reservoir. When a predetermined cracking pressure is reached, a valve opens and allows the liquid to flow through the cannula.

  • Patent number: 8518481
    Abstract: Provided is a micro electro mechanical systems (MEMS) device for use with an elongate structure. The MEMS device includes a generally planar substrate, a device wall layer formed upon the substrate, a septum cavity formed in the device wall layer, a channel formed in the device wall layer in fluid communication with the septum cavity, and a septum element disposed in the septum cavity. The septum element is formed of a viscoelastic material. The septum element defines a septum entry surface and a septum exit surface with the septum exit surface being exposed to the channel and disposed between the septum entry surface and the channel. The septum element is without any openings formed through the septum element extending between the septum entry and exit surfaces. Methods of manufacturing and interacting with the MEMS device are also provided.

  • Publication number: 20080039792
    Abstract: An implantable device for delivering a therapeutic agent to a patient is provided. The device includes a reservoir configured to contain a liquid comprising the therapeutic agent. The device further includes a cannula in fluid communication with the reservoir. The cannula has an outlet configured to be in fluid communication with the patient. The device further includes a first electrode and a second electrode, at least one of the first electrode and the second electrode is planar. The device further includes a material in electrical communication with the first and second electrodes. A voltage applied between the first electrode and the second electrode produces gas from the material, the gas forcing the liquid to flow from the reservoir to the outlet.

  • Publication number: 20040044545
    Abstract: Home care monitor systems are used to monitor physiological parameters of a user who is remotely located from a health care provider. The measured physiological parameters can be transmitted via telephone lines or a modem to a server component, which provides a queries database and a measurement database for storing the measured physiological parameters and generating queries to the user based on the measurements. The response to the queries, the measured physiological parameters and other data can be accessed by and transmitted to a remote health care provider to ascertain the health of the user.
