  • Publication number: 20230088749
    Abstract: A guidewire for use in penetrating through complex and stenosed lesions. The distal tip of the guidewire has a roughened surface to increase frictional engagement with calcified and fibrous tissue to increase the penetration of the distal tip and the guidewire into and through the lesion and reduce the likelihood of deflection of the guidewire tip. The average surface roughness of the distal tip is in the range from 1 micron to 200 microns.

  • Patent number: 11298251
    Abstract: Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium, tungsten, and nickel.

  • Publication number: 20210128883
    Abstract: A guidewire for use in intravascular procedures has an inner coil that is radiopaque and an outer coil that is non-radiopaque at the distal end of the guidewire. The radiopaque inner coil is visible under fluoroscopy so that the physician can monitor the location of the distal end of the guidewire during a procedure. The inner coil and the outer coil can be formed from a single wire or a multi-filar wire. The inner coil and the outer coil can have any of the following cross-sections for enhanced torquability: I-beam; vertical rectangular; vertical ellipse; square; peanut shape; vertical hexagonal; horizontal hexagonal; and horizontal ellipse.

  • Publication number: 20210128875
    Abstract: A shaping tool is used to form a bend in the distal end of a guidewire. The guidewire distal end is inserted through a channel and into a cavity of the shaping tool. Using hand pressure, a first member is moved axially relative to a second member of the shaping tool, thereby moving the cavity relative to the channel and imparting a bend in the distal end of the guidewire.

  • Publication number: 20190347635
    Abstract: Disclosed systems and methods include configuring behavior of a machine in a physical environment based on detected interactions with the physical environment. In some cases, an electronic identification device identifies a presence of an object in the physical environment. An attribute corresponding to the identified object is determined, the attribute identifying a characteristic of a user or group or users of the physical environment. The attribute is matched to a parameter indicating an environment device and a configuration of the environment device. In some cases, the configuration is based on historical information about interactions in the physical environment, and the user characteristic. Behavior of the environment device is modified based on the configuration.

  • Patent number: 10171368
    Abstract: In some embodiments, a non-transitory processor-readable medium stores code representing instructions to be executed by a processor that cause the processor to receive a data unit having a header portion. The code causes the processor to select a route based on the header portion and modify, based on the route being associated with a tunnel, the data unit to define a tunnel data unit including a tunnel header. The code causes the processor to select a loopback link from a set of loopback links of a loopback link aggregation group (LAG). The code further causes the processor to receive via the loopback link, the tunnel data unit and send the tunnel data unit via the tunnel based on the tunnel header.
