    摘要: Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together. If the device is left within the PFO track, the device is flattened from an expanded configuration to a flattened configuration, and the walls of the PFO track, adhering to the outer surface of the device, are pulled toward each other as the device flattens. The device may also include interior structure to hold the device in a flattened configuration.

    摘要: A three piece suspension with the first piece including a base region and a gimbal region for receiving a head slider mounted thereon. A base plate reinforces the base region to facilitate mounting the suspension to an actuator arm. A stiffener which has an engaging extension projecting from it strengthens the suspension without the need for strengthening flanges and applies the preload force to the slider.

    摘要: Some embodiments of a medical device anchor system include an anchor sleeve that receives a catheter (or other medical instrument) though a working channel of the anchor sleeve. The anchor sleeve may include a first actuator that controls the extension of one or more subcutaneous tines into the subcutaneous region under the skin. The anchor sleeve can also include a second actuator that can cause the anchor sleeve to lock onto an outer portion of the catheter (or other medical instrument) arrange in the working channel.
