  • Patent number: 10463446
    Abstract: A biopsy marking apparatus for placing a radiopaque marker at the location of a percutaneous biopsy. The biopsy marking apparatus comprises an introducer in combination with a radiopaque marker. The introducer ejects the radiopaque marker at the location of the biopsy. The introducer is configured to completely eject the radiopaque marker and prevent it from being subsequently drawn into the introducer as the introducer is removed from the biopsied tissue mass. The radiopaque marker has enhanced radiopaque characteristics and enhanced non-migration characteristics.

  • Publication number: 20190328483
    Abstract: A method of operating a marking device includes defining an initial condition wherein a cannula is in an extended position and a stylet is in a ready position in the extended cannula, and, starting from the initial condition with the cannula in the extended position, sequentially: effecting movement of the stylet from a ready position to an implant position, ejecting an imaging marker through a distal opening in a cannula distal end of the cannula, and then; effecting a simultaneous unitary retraction of the cannula and stylet after ejection of the imaging marker from the distal opening in the cannula distal end.

  • Patent number: 10435775
    Abstract: Methods of refining the grain size of titanium and titanium alloys include multiple upset and draw forging. Titanium and titanium alloy workpieces are heated to a workpiece forging temperature within a workpiece forging temperature range in the alpha+beta phase field. The workpiece may comprise a starting cross-sectional dimension. The workpiece is upset forged in the workpiece forging temperature range. After upsetting, the workpiece is multiple pass draw forged in the workpiece forging temperature range. Multiple pass draw forging may comprise incrementally rotating the workpiece in a rotational direction followed by draw forging the workpiece after each incremental rotation. Incrementally rotating and draw forging the workpiece is repeated until the workpiece comprises substantially the same starting cross-sectional dimension.

  • Patent number: 10407745
    Abstract: A method of producing an article selected from a titanium article and a titanium alloy article comprises melting feed materials with a source of hydrogen to form a molten heat of titanium or a titanium alloy, and casting at least a portion of the molten heat to form a hydrogenated titanium or titanium alloy ingot. The hydrogenated ingot is deformed at an elevated temperature to form a worked article comprising a cross-sectional area smaller than a cross-sectional area of the hydrogenated ingot. The worked article is dehydrogenated to reduce a hydrogen content of the worked article. In certain non-limiting embodiments of the method, the dehydrogenated article comprises an average ?-phase particle size of less than 10 microns in the longest dimension.

  • Publication number: 20190261914
    Abstract: Reference imagery of dermatological conditions is compiled in a crowd-sourced database (contributed by clinicians and/or the lay public), together with associated diagnosis information. A user later submits a query image to the system (e.g., captured with a smartphone). Image-based derivatives for the query image are determined (e.g., color histograms, FFT-based metrics, etc.), and are compared against similar derivatives computed from the reference imagery. This comparison identifies diseases that are not consistent with the query image, and such information is reported to the user. Depending on the size of the database, and the specificity of the data, 90% or more of candidate conditions may be effectively ruled-out, possibly sparing the user from expensive and painful biopsy procedures, and granting some peace of mind (e.g., knowledge that an emerging pattern of small lesions on a forearm is probably not caused by shingles, bedbugs, malaria or AIDS).

  • Patent number: 10357328
    Abstract: A marking device according to one embodiment of the invention comprises a handle, a cannula having a cannula distal end and slidably mounted to the handle, and a stylet having a stylet distal end and slidably mounted to the handle in the cannula. The stylet distal end is spaced proximally of the cannula distal end to form a marker recess that receives an imaging marker. The marking device further comprises an actuator operably coupled to the cannula to effect retraction of the cannula into the handle following implantation of the imaging marker. The imaging marker can be implanted by advancing the stylet relative to the cannula to eject the imaging marker from the marker recess, or the cannula can be retracted relative to the stylet to expose the imaging marker.

  • Patent number: 10342635
    Abstract: A marking device includes a handle defining a hollow interior, and a delivery assembly slidably mounted to the handle. The delivery assembly includes a cannula, a stylet assembly, an imaging marker, and an actuator. The cannula has a cannula distal end with a marker recess. The imaging marker is disposed within the marker recess. The actuator is operably coupled to the delivery assembly and is operable to transition the delivery assembly through at least three configurations: a first configuration characterized in that the cannula is positioned in an extended position and the stylet assembly is positioned in a ready position; a second configuration characterized in that the cannula is positioned in the extended position and the stylet assembly is positioned in an implant position; and a third configuration characterized in that the cannula is positioned in the retracted cannula position and the stylet is retracted into the handle.

  • Patent number: 8499681
    Abstract: A fluid displacement device, particularly for use of the device to pressurize balloon catheters, or the like. The device includes a plunger which is displaceable through a housing, and an actuating mechanism which engages the plunger. The actuating mechanism includes a nut member that is biased into engagement with a threaded portion of the plunger. The device has a press-to-release feature wherein the plunger is instantly releaseable by simply depressing a control surface to overcome a restorative spring force. Subsequently, the plunger can be translated using macro movements (i.e., by pushing or pulling the plunger).

  • Patent number: 8141699
    Abstract: An improved contact lens case which includes domes that are provided on hinged members. Preferably, the contact lens case is configured to efficiently utilize space and volume such that no more than 10 cc's of contact lens solution are required to disinfect contact lenses in the case. The hinged members are preferably non-planar which allows the domes to be provided on the hinged members, and allows the use of deep larger diameter, back-to-back cages on the stem, without having to resort to using more than 10 cc's of fluid to immerse contact lenses that are disposed on the domes, between each of the domes and a respective cage. Each of the hinged members has a cylindrically-curved shell form in which the axis of its curve is approximately parallel to the central axis of the central planar stem member.
