  • Patent number: 9155495
    Abstract: A syringe-based device includes a housing, a pre-sample reservoir, and an actuator. The housing defines an inner volume between a substantially open proximal end portion and a distal end portion that includes a port couplable to a lumen-defining device. The pre-sample reservoir is fluidically couplable to the port to receive and isolate a first volume of bodily fluid. The actuator is at least partially disposed in the inner volume and has a proximal end portion that includes an engagement portion and a distal end portion that includes a sealing member. The engagement portion is configured to allow a user to selectively move the actuator between a first configuration such that bodily fluid can flow from the port to the pre-sample reservoir, and a second configuration such that bodily fluid can flow from the port to a sample reservoir defined at least in part by the sealing member and the housing.

  • Patent number: 9149576
    Abstract: An apparatus includes a cannula assembly, a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing includes an inlet port removably coupled to the cannula assembly and defines an inner volume. The fluid reservoir is fluidically coupled to the housing and configured to receive and isolate a volume of bodily fluid from a patient. The flow control mechanism is at least partially disposed in the inner volume. The actuator is operably coupled to the flow control mechanism and is configured to move the flow control mechanism between a first configuration, in which bodily fluid can flow, via a fluid flow path defined by the flow control mechanism, from the cannula assembly, through the inlet port and into the fluid reservoir, to a second configuration, in which the fluid reservoir is fluidically isolated from the cannula assembly.

  • Publication number: 20150257691
    Abstract: An apparatus includes a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing defines an inner volume and has an inlet port that can be fluidically coupled to a patient and an outlet port. The fluid reservoir is disposed in the inner volume to receive and isolate a first volume of a bodily-fluid. The flow control mechanism is rotatable in the housing from a first configuration, in which a first lumen places the inlet port is in fluid communication with the fluid reservoir, and a second configuration, in which a second lumen places the inlet port in fluid communication with the outlet port. The actuator is configured to create a negative pressure in the fluid reservoir and is configured to rotate the flow control mechanism from the first configuration to the second configuration after the first volume of bodily-fluid is received in the fluid reservoir.

  • Publication number: 20150250414
    Abstract: A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient.

  • Publication number: 20150246352
    Abstract: An apparatus includes a transfer adapter, a puncture member, a disinfection member, and a fluid reservoir. The transfer adapter has a proximal end portion and a distal end portion, and defines an inner volume configured to receive the puncture member. The transfer adapter is coupled to the disinfection member. The distal end portion of the transfer adapter includes a port fluidically coupled to the puncture member and configured to be placed in fluid communication with a bodily-fluid of a patient. The proximal end portion is configured to receive a portion of the fluid reservoir to allow the fluid reservoir to be moved within the inner volume between a first position, in which a surface of the fluid reservoir is placed in contact with the disinfection member, and a second position, in which the puncture member punctures the surface to place the puncture member in fluid communication with the fluid reservoir.

  • Publication number: 20140233184
    Abstract: A method and system for management of thermal energy produced during transcutaneous energy transmission to provide power to energize implanted medical devices. A phase changing material (PCM) acts as a heat sink to absorb thermal energy generated during the energy transfer process. The PCM can be thermally coupled to tissue proximate to an implanted medical device, enabling heat generated within the implantable device to be absorbed. The generation of heat during the energy transfer process is primarily caused by eddy currents induced in the implantable device by the magnetic flux produced by the energy transfer system. The PCM can also be used to absorb heat generated by the device producing the magnetic flux that is used to transcutaneously transfer electrical power to recharge a rechargeable power source or energize the implanted medical device.
