Abstract: In one embodiment, a syringe system includes a dual barrel syringe, a dual chamber mixing cartridge, and a plurality of mixing masses. The dual barrel syringe includes a first diluent chamber, a second diluent chamber, a first port fluidically coupled to the first diluent chamber, and a second port fluidically coupled to the second diluent chamber. The dual chamber mixing cartridge is configured to mount to the dual barrel syringe and includes a first powder chamber, a second powder chamber, a first cartridge port fluidically coupled to the first powder chamber, and a second cartridge port fluidically coupled to the second powder chamber. The plurality of mixing masses are positioned within the first powder chamber and the second powder chamber.

Abstract: An atherectomy catheter for performing an atherectomy procedure, the atherectomy catheter includes a catheter body defining one or more lumens, a core wire extending through a core wire lumen of the one or more lumens of the catheter body, and an abrasive bead slidably mounted to the core wire. The core wire is configured to be coupled to an excitation device and operation of the excitation device causes the abrasive bead to rotate about and slide longitudinally along the core wire.

Abstract: In one embodiment, a mixing syringe assembly for mixing two constituent materials includes a barrel body, a plunger, a sealing device, and one or more mixing masses. The plunger is slidably positioned within the barrel body. The sealing device divides the barrel body into a first constituent material section and a second constituent material section. The one or more mixing masses are positioned within one of the first constituent material section and the second constituent material section. The sealing device is operable to adjust from a sealing configuration to a non-sealing configuration to allow for a first constituent material from the first constituent material section to move into the second constituent material section upon movement of the plunger along the barrel body and be mixed therein with the one or more mixing masses.

Abstract: The present disclosure relates to ultrasonic catheters including vibration wires that are positionable in a retracted position and an extended position, and their methods of use. In operation, catheters according to the present disclosure are operable in an occlusion crossing mode, in which the catheter emits ultrasonic energy with the vibration wires in the retracted position and in an atherectomy mode, in which the catheter emits ultrasonic energy with the vibration wires in the extended position, causing the vibration wires to oscillate. The vibration wires may directly or indirectly engage plaque within an artery, causing the plaque to break free from the artery wall. The oscillation of the vibration wires may be less abrasive than conventional cutting elements used in atherectomy procedures, such that catheters according to the present disclosure may cause less trauma to artery walls as compared to conventional atherectomy devices.

Abstract: Systems and methods for tumor ablation with controlled precision of a temperature profile utilizing a tumor ablation probe device may include disposing a distal end of the tumor ablation probe device in a tissue, the distal end including a plurality of electrothermal modules (ETMs) on probe arm(s), each ETM including a first surface component electrically connected to a second surface component; supplying a first voltage of a first polarity or a second voltage of a second polarity to at least one ETM, and repeatedly alternating between the first polarity and the second polarity based on a time sequence cycle. When the first polarity is supplied, the ETM heats the first surface component and cools the second surface component, and when the second polarity is supplied, the ETM cools the first surface component and heats the second surface component. Each ETM and/or probe arm is configured for independent control.

Abstract: A securement device configured to secure an external portion of a medical device to the skin surface of a patient after an internal portion of the device has been placed in the patient is disclosed. The securement device includes a retainer that is employed to securely retain the external portion of the medical device in place. The retainer is attached to a base, such as an adhesive pad that adhesively attaches to the skin surface. In one embodiment, therefore, a retainer comprises a body defining a channel configured to receive therein a portion of the medical device, and at least one foot extending from the body that is configured to stabilize the retainer with respect to a skin surface. The retainer body further includes a nose that is configured to deflect a portion of the external portion of the medical device toward the skin insertion site.

Abstract: In one embodiment, the present invention is directed to a logic analyzer such as may be implemented on a system-on-chip or another semiconductor device. The analyzer can include multiple lanes each having a filter to receive and filter debug data, a compressor to compress the debug data passed by the filter, a buffer, and a controller to store the compressed debug data into the buffer, where the compressed debug data can be stored without timing information. Other embodiments are described and claimed.
