Patent number: 8416293Abstract: A plasma monitoring device includes a plasma supplier including a power supply, a reaction gas supply line, and an emission nozzle for emitting plasma, which is generated therein, toward an object; a camera unit for obtaining an image of the plasma emission state; and a controller for obtaining a measurement value by converting pixel information of the image into a numerical value and comparing it with a reference value, which is a measurement value in a normal emission state, to check the plasma emission state. The camera unit obtains an image of the plasma emission state, and the controller analyzes the image to obtain a measurement value, which is used to monitor the state of plasma in real time and control the amount of reaction gas supplied to the plasma supplier and the plasma discharge condition, so that plasma is evenly emitted from the plasma supplier.Type: GrantFiled: April 10, 2008Date of Patent: April 9, 2013Assignee: SNU Precision Co.

Patent number: 8414558Abstract: A system is provided for performing injections in the ventricle of a patient. The system includes an injection catheter with a proximal and distal end. Importantly, a flexible array is mounted at the distal end of the injection catheter and is moveable between a protective configuration and a flared configuration. Also, a needle of variable length is mounted on the distal end of the injection catheter and is covered by the flexible array when the array is in its protective configuration. In order to manipulate the flexible array, a locking mechanism is mounted on the proximal end of the injection catheter for engagement with the flexible array. When selectively operated, the locking mechanism moves the array from its protective configuration to the flared configuration, holds the array in its flared configuration for an injection, and subsequently moves the array back to its protective configuration.Type: GrantFiled: November 5, 2010Date of Patent: April 9, 2013Inventor: Richard A.

Patent number: 8361054Abstract: The present embodiments provide apparatus and methods suitable for containing and delivering a therapeutic agent to a target site. The apparatus generally comprises at least one container for holding a therapeutic agent, and a pressure source for facilitating delivery of the therapeutic agent. In one embodiment, the pressure source may be placed in selective fluid communication with a proximal region of the container and fluid from the pressure source may flow through at least a portion of the container to urge the therapeutic agent through the container towards the target site. In an alternative embodiment, the pressure source may be selectively in fluid communication with either a first hollow tube and the container so that therapeutic agent is urged into a catheter, or with a second hollow tube and a catheter so that a fluid from the pressure source bypasses the container and enters the catheter.Type: GrantFiled: December 8, 2009Date of Patent: January 29, 2013Assignee: Cook Medical Technologies LLCInventors: Richard W.

Patent number: 8348923Abstract: An infusion system, which may be a closed loop, or “semi-closed-loop”, infusion system, uses state variable feedback to control the rate at which fluid is infused into a user's body. The closed loop system includes a sensor system, a controller, and a delivery system. The “semi-closed-loop” system further includes prompts that provide indications to the user prior to fluid delivery. The sensor system includes a sensor for monitoring a condition of the user and produces a sensor signal which is representative of the user's condition. The delivery system infuses a fluid into the user at a rate dictated by the commands from the controller. The system may use three state variables, e.g., subcutaneous insulin concentration, plasma insulin concentration, and insulin effect, and corresponding gains, to calculate an additional amount of fluid to be infused with a bolus and to be removed from the basal delivery of the fluid.Type: GrantFiled: August 12, 2010Date of Patent: January 8, 2013Assignee: Medtronic Minimed, Inc.Inventors: Sami S.
