  • Publication number: 20220177824
    Abstract: Material processing apparatus, systems, methods, and products are described. An example of a material processing apparatus includes a holding member, a base, a tensioning member, an actuator, and a first inner member. The holding member defines a holding member passageway. The base is attached to the holding member. The tensioning member is partially disposed within the holding member passageway. The tensioning member defines a tensioning member passageway. The tensioning member is moveable relative to the holding member between a first position and a second position. The actuator is attached to the tensioning member and is moveable in a first direction and a second direction. Movement of the actuator results in movement of the tensioning member between its first position and second position. The first inner member is adapted to be disposed within the tensioning member passageway.

  • Publication number: 20070203520
    Abstract: Endovascular filter (10) including a plurality of struts (14) with distal ends (18) adapted to anchor the filter to the vessel wall after deployment, such as by having barbs (20), the filter being adapted to be retrieved if desired. Strut distal ends (18) are coated with an antiproliferative agent (40) that inhibits the ingrowth of tissue around the filter, thereby permitting the filter to be retrieved and removed atraumatically after a prolonged period of time, thus extending the useful life of the retrievable filter. Optionally, the proximal end (22) of the filter may also be so coated, or the entire filter.

  • Publication number: 20060161243
    Abstract: A variable curvature stent limb is disclosed herein. A stent derived from a plurality of these variable curvature stent limbs may be highly compressible, such that it is compatible with a low-profile delivery device. This stent may be useful over a wider range of body vessel diameters and may possess a greater fatigue life, since this stent may provide a more controlled constant radial force.

  • Publication number: 20050278021
    Abstract: A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith.

  • Patent number: 4473080
    Abstract: An instrument for measuring blood pressure by sensing the Korotkoff sounds which prevail only between the systolic and diastolic point. The instrument used is essentially a hand-held device. The instrument has a pressure-sensitive element made up of a flexible material containing fluid and crystal transducer supported on the flexible material which responds to the Korotkoff sounds. The sensor is made in a unique geometrical structure shaped to fit between bones and tendons over an artery. The crystal operates through an amplifier, a high pass filter and low pass filter through a comparator to a one shot enabling means connected to a panel meter. The pressure on the fluid in the sensed by a pressure sensor that is in contact with the fluid in the sensor which is connected to the panel digital meter. The digital display shows the pressure exerted on the artery at each Korotkoff sound. A LED shows that pulses are present.
