    摘要: A device and method for hermetically sealing a medical device is provided. In one aspect, a silicon device is coupled to a sensor, such as a pressure transducer, which benefits from having direct contact with its environment, which in many cases, is the human body. Thus, a method to hermetically seal the non-sensing portion of a silicon device while allowing the sensing portion (e.g. the pressure transducer) to have direct contact with the body is provided. In one aspect, a silicon chip, a gold preform and a metallic housing are each primed for sealing and are assembled. The assembly is then heated to react the gold preform to the silicon chip and to form a molten gold-silicon alloy in-situ to bind the metallic housing to the non-sensing portion of the silicon chip. In this way, the non-sensing portion of the silicon chip is hermetically sealed and protected from exposure, while still permitting exposure of the sensing portion to the environment.

    摘要: A method for accessing a target site in the body by transferring a guidewire from an initial insertion site on the body to a different insertion site on the body is provided. In one aspect, a method for transferring a medical device or component, such as a sensor lead, from an initial insertion site to another insertion site is also provided. A guidewire of sufficient length, pliancy and deformability to perform a transfer from one insertion site to another insertion site is provided. In one aspect, the guidewire comprises a removable core mandrel to increase rigidity, facilitate insertion and/or improve steerability. A kit or system, comprising introducers, guidewires and catheters for performing a guidewire or device transfer is also provided.

    摘要: Techniques are provided for detecting a clinically-significant pulmonary fluid accumulation within a patient using a pacemaker or other implantable medical device. Briefly, the device detects left atrial pressure (LAP) within the patient and tracks changes in the LAP values over time that are indicative of possible pulmonary fluid accumulation within the patient. The device determines whether the changes in LAP values are sufficiently elevated and prolonged to warrant clinical intervention using, e.g., a predictor model-based technique. If the fluid accumulation is clinically significant, the device then generates warning signals, records diagnostics, controls therapy and/or titrates diuretics. False positive detections of pulmonary edema due to transients in LAP are avoided with this technique. Pulmonary artery pressure (PAP)-based techniques are also described.
