Patent number: 10119526Abstract: A variety of embodiments of an at least partially flexible actuator are provided. The actuator includes a phase change material contained within an at least partially flexible enclosure of the actuator. Application of heat, using a heater of the actuator, to the phase change material causes the phase change material to boil, increasing the volume of the actuator and/or increasing a pressure within the actuator. As a result, the actuator can be used to apply a force to objects in an environment of interest. The actuator could be incorporated into a wearable blood pressure cuff and used to apply pressure to a body part of a wearer in order to detect a blood pressure of the wearer. In other examples, the actuator could be incorporated into a wearable device and used to secure a sensor or other elements of the device against skin of a wearer.Type: GrantFiled: December 10, 2015Date of Patent: November 6, 2018Assignee: Verily Life Sciences LLCInventors: Eric Peeters, Peter Howard Smith, Bejamin David Krasnow

Publication number: 20180078711Abstract: An apparatus and methods for tracking administering of medication by syringes is provided. The apparatus may include a plunger head for a syringe. The plunger head may include a transducer that sends and receives ultrasonic signals. The plunger may also include an antenna and a microcontroller that interfaces with the transducer and the antenna. The plunger may also include a power source that powers the microcontroller and the transducer. The transducer, the antenna, the microcontroller, and the power source may be at least partially encapsulated in an elastomer housing that fits within a barrel of the syringe. The microcontroller may be programmed with instructions to calculate data representative of the quantity of medication dispensed from the barrel and transmit the data to a remote device via the antenna.Type: ApplicationFiled: November 30, 2017Publication date: March 22, 2018Inventors: Benjamin David Krasnow, Peter Howard Smith, Travis Deyle, Russell Mirov

Publication number: 20170319119Abstract: Devices are provided to automatically access blood from beneath or within skin. These devices include an injector configured to drive a needle into the skin and subsequently to retract the needle from the skin. These devices additionally include a seal to which suction is applied. To drive the needle into the skin, the needle is first driven through the seal, creating at least one hole in the seal. The suction applied to the seal acts to draw blood from the puncture formed in the skin by the needle, through the at least one hole in the seal, and to a sensor, blood storage element, or other payload. These devices can be wearable and configured to automatically access blood from skin, for example, to access blood from the skin at one or more points in time while a wearer of a device is sleeping.Type: ApplicationFiled: July 26, 2017Publication date: November 9, 2017Inventors: Benjamin David Krasnow, Eric Peeters, Peter Howard Smith

Publication number: 20170312445Abstract: Various apparatuses and methods for tracking the administration of medication by medication injection devices are provided. A plunger head for a medication injection device may include a first component that houses electronic components and a second component that couples to the first component to form the plunger head. When the plunger head is installed within a barrel of the medication injection device the second component may separate the first component from medication contained within the barrel.Type: ApplicationFiled: October 25, 2016Publication date: November 2, 2017Inventors: Russell Mirov, Benjamin David Krasnow, Peter Howard Smith, Travis Deyle, Brett Schleicher

Publication number: 20170312455Abstract: A medication injection device includes a barrel and a plunger disposed to dispense a fluid from the barrel. A dosage tracking system is coupled to output data indicative of the fluid dispensed. A controller is disposed within the medication injection device and coupled to receive the data from the dosage tracking system. The controller includes logic that when executed by the controller causes the controller to perform operations including determining, based on the data, whether an air shot event occurred while dispensing the fluid.Type: ApplicationFiled: April 27, 2017Publication date: November 2, 2017Inventors: Russell Mirov, Benjamin David Krasnow, Peter Howard Smith, Travis Deyle

Publication number: 20160338582Abstract: A drive assembly for driving an imaging catheter has a rotatable fiber and a rotatable drive shaft. The drive assembly includes a fiber optic rotating junction and a motor configured to rotate the rotatable portion of the fiber optic rotating junction. In some embodiments, the drive assembly includes a sensor configured to detect a rotational position of the fiber optic rotating junction and a processor configured to obtain the detected rotational position and stop the motor only when the fiber optic rotating junction is in a predetermined rotational position. In some embodiments, the motor includes a hollow shaft through which at least a portion of the fiber optic rotating junction extends.Type: ApplicationFiled: May 23, 2016Publication date: November 24, 2016Inventors: Brian Y.

Publication number: 20160256106Abstract: Devices are provided to automatically inject drugs or other payloads into or beneath skin. These devices include an injector configured to drive a hollow needle into the skin and subsequently to deliver the payload through the hollow needle. Applied suction acts to draw blood from the puncture formed in the skin through the hollow needle, into the device, and to a sensor, blood storage element, or other payload. In some examples, the blood is drawn through the hollow needle when the hollow needle is penetrating the skin. In some examples, these devices are additionally configured to retract the hollow needle from the skin and/or to perform some other functions. These devices can be wearable and configured to automatically access blood or deliver a payload into skin, for example, to operate at one or more points in time while a wearer of a device is sleeping.Type: ApplicationFiled: March 2, 2015Publication date: September 8, 2016Inventors: Benjamin David Krasnow, Eric Peeters, Peter Howard Smith
