    摘要： A system for preparing an ablation procedure is disclosed. The system comprises a generator for generating electrical pulses, a plurality of probes for delivering the electrical pulses to a target tissue, one or more sensors for indicating a position of the probes, a display device, and a processor. The processor is configured to receive an image of the target tissue, obtain a planned probe arrangement for the plurality of probes, identify a projected position for an origin probe based on the image and the planned probe arrangement, and determine a real-time position of the origin probe based on signals from the sensors. The processor is further configured to display the projected position and the real-time position for the origin probe superimposed over the image on a display device, and determine a placed position of the origin probe based on the real-time position.

    摘要： A valve for controlling material flow through a catheter, comprises a first flexible member including a first moveable element, wherein, when the first moveable element is in the open position, material may flow past the first flexible member through a first lumen of the catheter and, when the first moveable element is in the closed position, flow through the first lumen is prevented and a first biasing member coupled to the first flexible member for biasing the first moveable member toward the closed position.

    摘要： A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.

    摘要： A medical device for removing a material from a hollow anatomical structure is provided. The device may include a shaft member. The device may include an expandable centering element near the distal end of the device. The device may include a macerator element either attached to the shaft or independent and freely moveable from the shaft. The device may include an aspiration lumen in for removal of material. The device may include a drive shaft attached to a motor and used to rotate the macerator element.

    摘要： A system for synchronizing application of treatment signals with a cardiac rhythm is provided. The system includes a memory that receives and stores a synchronization signal indicating that a predetermined phase such as R-wave of a cardiac rhythm of a patient has started. A synchronization module analyzes whether the stored synchronization signal is erroneous and if so, prevents a medical treatment device from applying a treatment energy signal such as an IRE pulse to a patient to take into account an irregular heart beat and noise in the synchronization signal in order to maximize safety of the patient.
