  • Publication number: 20260137136
    Abstract: A sock with decorative strap as ankle and calf wrap is provided. The sock comprises a low-cut satin sock with edges below malleolus levels of a user and two vertical straps, one each attached at lower ends to sock edges at one of inside and outside areas of user ankle at attachment points forward of each malleolus. The sock also comprises binding fold-over elastic (FOE) covering the edges. The straps extend upward and wrap about a lower leg and tie in a bow at upper ends. The straps wrap in a crisscross and spiraling manner up the lower leg. Lower strap ends tuck inside the edges and inside the binding FOE. Lower ends tucking inside the binding FOE promote the lower ends not making contact with the user's skin. The system further comprises gel anti-slip features on a sole area. The straps are of length of about 26 inches each.

  • Patent number: 12611522
    Abstract: A catheter includes a handle with torqueing and steering mechanisms. The torqueing mechanism includes a rotatable nosecone and a bearing coupled to the nosecone to be rotatable therewith. The bearing is concentrically disposed over a shaft of the catheter. The steering mechanism includes a rack coupled to the bearing to be slideable therewith and a pull wire having a proximal end attached to the bearing and a distal end attached to a distal portion of the shaft. Rotation of the nosecone causes an entire length of the shaft to rotate and axial movement of the rack tensions the pull wire to bend the distal portion of the shaft. A valve relief component is slidingly disposed over the shaft and is configured to dock onto the handle when not in use.

  • Patent number: 12427231
    Abstract: Biodegradable magnesium alloy implantable medical devices are protected to delay onset of corrosion, and thus biodegradability, or to corrode more uniformly. The protection allows for extended effective use of the devices while maintaining biodegradability. Examples of protective coatings include conversion coatings that at least partially remove exposed second phases from a surface of the magnesium alloy and coatings that provide a barrier between water and the surface of the magnesium alloy.

  • Patent number: 12229073
    Abstract: In one embodiment, an apparatus includes: a plurality of cores to execute instructions; a firmware agent to execute a first firmware; a Peripheral Component Interconnect Express (PCIe) interface to communicate with a device via a PCIe link; and a boot agent coupled to the PCIe interface to download the PCIe firmware from a non-volatile memory and provide the PCIe firmware to the PCIe interface. The PCIe interface may receive a PCIe firmware for the PCIe interface before the firmware agent is to receive the first firmware. Other embodiments are described and claimed.

  • Publication number: 20250009536
    Abstract: A crimper for altering an implantable medical device from an uncompressed state to a compressed state. The crimper includes a plurality of crimper elements that define a crimper channel, each of the crimper elements including a non-planar surface that forms a portion of the crimper channel. Each non-planar surface is configured to apply non-uniform radial compression along a length of the implantable medical device during operation of the crimper when altering the implantable medical device from the uncompressed state to the compressed state. The crimper also includes handle configured to operate the crimper. Actuation of the handle decreases a volume of the crimper chamber to transition the implantable medical device from the uncompressed state to the compressed state.

  • Patent number: 11974919
    Abstract: Delivery devices for delivery of a stented prosthetic heart valve. Various delivery devices include an outer sheath assembly including an outer sheath connected to a capsule that is advanced proximally to retain the prosthetic valve, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper to provide a smooth transition of the capsule over the prosthetic valve during loading and recapture procedures. The bumper is expandable from a first position to a second position in which a distal end of the bumper is expanded to increase its diameter. The bumper can be biased in the second, expanded position so that the bumper automatically transitions to the expanded position upon retraction of the outer sheath.

  • Publication number: 20230329730
    Abstract: The present invention is directed to a manually actuated aspiration device, aspiration system and a method of use to enable and facilitate en bloc removal of undesirable intravascular material, including, but not limited to, thrombus, embolus, or vegetation through a working lumen of a suction cannula during minimally invasive percutaneous procedures. The aspiration device includes valves oriented in opposite direction to control the fluid flow through the aspiration system and into a waste collection component. Alternatively, the aspiration system further comprises a filter that removes undesirable intravascular material prior to reinfusing blood into a patient's vasculature.
