  • Patent number: 11864794
    Abstract: Percutaneous access systems, including trocars, for accessing desired locations within a subject's body through the subject's skin or other tissues that are configured to minimize incision sizes are disclosed. Such a percutaneous access system includes a cannula and an obturator. The cannula includes a passageway with a tapered section and an expandable section at its distal end. The expandable section may include leaves that are configured to extend radially outward as an elongated instrument that has an outer diameter that exceeds a minimum relaxed inner diameter of the tapered section of the passageway is forced through the tapered section. Methods for using such a percutaneous access system, including medical procedures, are also disclosed.

  • Patent number: 11317901
    Abstract: Among other things, methods and apparatus for inserting devices for closing a tissue opening are disclosed. An anchoring or sealing member has one or more stems and/or filaments that are offset from the center of the member, so that lateral adjustments or movements of the anchoring or sealing member do not uncover the opening, cause the anchoring or sealing member to stick through or pull through the opening. Embodiments including a valve adapted to accommodate a guide wire for addressing emergencies are also disclosed.

  • Patent number: 11040270
    Abstract: A billiard cue storage assembly for storing a chalking a plurality of billiard sticks includes a stand that has an upper disk spaced from a lower disk. Each of the upper disk and the lower disk has a plurality of holes therein for insertably receiving a billiard cue. Additionally, each of the holes in the lower disk insertably receives a cube of billiard chalk. A rotation disk is rotatably coupled to the lower disk and the rotation disk has a slot therein. The slot is alignable with a respective one of the holes in the lower disk to facilitate the cube of billiard chalk to be urged downwardly out of the respective hole in the lower disk. A plurality of feet is each coupled to the lower disk to support the lower disk above a support surface.

  • Patent number: 8932325
    Abstract: Among other things, there are disclosed apparatuses and methods for medically sealing an opening in a vessel or wall. For example, in medical applications, a delivery tube is provided for insertion through a sheath into a vessel (e.g. a blood vessel). A dome-shaped seal fixed to a filament, an absorbent and/or compressible buffer, and a locking member are provided in the delivery tube. The delivery tube is configured so that it can be inserted into the vessel through a sheath. Tension is maintained on the filament to hold the seal against the tube or sheath. The sheath is pulled out, which pulls out the tube at the same time, leaving the seal over the opening in the vessel wall. The locking member compresses the buffer against the outside of the vessel and with the filament holds the seal in place against the inside of a vessel.

  • Patent number: 7913185
    Abstract: A graphical user interface allows a user to create an image having a pop-up menu which is exportable to a target computer without the creating user being required to know how to program in JAVASCRIPTâ„¢. Using menu selection in the application in which the image is running, the creating user may insert a pop-up menu instruction associated with an object and positioned at a desired location within the image. The inserted pop-up menu instruction then causes the creating computer to invoke its own routines that construct an exportable JAVASCRIPTâ„¢ file that allows for a pop-up menu associated with the desired object to be displayed on the screen of a target system.

  • Patent number: 7568534
    Abstract: A polycrystalline diamond cutting element for earth boring drill bits presents regions of different abrasion resistance to the earthen formation when in operation. The cutting element has an end working surface and a region which is substantially free of catalyzing material, forming a layer. In operation, this layer wears at a different rate than the underlying material causing a pair of protruding lips to form. The end working surface may be substantially planar or frusto-conical in form.

  • Publication number: 20080142267
    Abstract: A polycrystalline diamond cutting element for earth boring drill bits presents at least three regions of different abrasion resistance to the earthen formation when in operation. The cutting element has an end working surface and the regions, which are substantially free of catalyzing material, form a series of at least three layers. In operation, these layers wear at different rates causing a series of protruding lips. The end working surface may be substantially planar or frusto-conical in form.

  • 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: 20070153407
    Abstract: A re-positionable mirror in accordance with an exemplary embodiment is provided. The re-positionable mirror includes a control lever and a reflective surface. The control lever is secured to the mirror and manipulates the reflective surface into one of a first position, a second position, and a third position. The reflective surface provides a view along a first line of sight at the first position. The reflective surface provides another view along a second line of sight at the second position, the second line of sight being angularly disposed above the first line of sight. The reflective surface provides another view along a third line of sight at the third position, the third line of sight being angularly disposed below the first line of sight.
