  • Patent number: 10265100
    Abstract: Transradial access devices, systems, and methods. An exemplary device of the present disclosure for providing access to a vessel or other luminal organ and to prevent overperforation of the same comprises a needle having a needle tip and at least one current element positioned thereon or embedded therein at or near the needle tip, a sheath positioned around at least part of the needle, and a protractor in communication with the needle, whereby engagement of the protractor causes the needle tip to protract from the sheath through the aperture, and whereby release of the protractor causes the needle tip to retract through the aperture into the sheath. Activation of the at least one current element can facilitation vasodilation of the vessel or other luminal organ.

  • Patent number: 10265164
    Abstract: This intraocular lens (IOL) injector cartridge has a proximal opening in a main body for receiving an IOL. The main body has a lumen that extends longitudinally to a distal end having an opening smaller than the IOL. Passage through the lumen compresses or rolls the IOL so that when the distal end is inserted through a small incision in the eye the IOL can be expelled into the capsular bag. The distal end of the cartridge is beveled with a leading tip in front of a trailing heel. The characteristics of the beveled end are such that damage to the IOL is reduced. The bevel may be straight or curved and includes a distal face defined by the thickness of the distal end between the lumen and an exterior surface. The distal face may be flush with the bevel or chamfered. An inner corner angle between the distal face and the lumen is ?60° to reduce the chance of scratching the IOL as it passes out of the distal opening.

  • Patent number: 10258444
    Abstract: An osteotome for sinus lift procedures includes a body interchangeable with various handles. The body includes a shaft that is releasably received into the handle, and a tip portion. The tip portion may be directly utilized for ridge expansion/bone compression, or a succession of tip members may instead be received thereon to provide suitable diameter escalation to create the socket. A conduit in the tip portion interconnects with a conduit in a hydration port and a conduit in a tip member. A hose couples the hydration port to a syringe, to deliver fluid out the tip member to lift the membrane. Graduated syringe markings permit delivery of measured fluid quantities to control the amount of lift. A second hydration port is coupled to a graduated cylinder through a valve, which is opened after lifting is complete, to measure the fluid released. A loss of fluid measured indicates a sinus tear.

  • Patent number: 10238834
    Abstract: Catheters and methods for supporting a guidewire or delivering a radiopaque, diagnostic or therapeutic agent through a vessel stenosis or other tortuous anatomy are disclosed. A catheter can comprise an elongate shaft body and a tip member disposed at a distal end of the shaft body. The shaft body can extend from a proximal end to the distal end and can define an inner lumen. The shaft body can include a liner, a braid member surrounding the liner, a multi-layer coil surrounding the braid member, and a polymer cover surrounding the multi-layer coil. An outer surface portion of the polymer cover can include one or more helical threads, which can be enveloped in an outer wrapper. The tip member can be made from a metal or a polymer. Polymer tip members can include a hard or semi-hard distal tip.

  • Patent number: 10231701
    Abstract: An elongated member such as a catheter that uses ultrasound or optical coherence tomography “OCT”) technology to approximate the dimensions of a structure into which the catheter has been placed. The catheter includes multiple ultrasound transducers arranged in an annular or circumferential configuration on, embedded into or within the body of the elongated member so that distance measurements can be obtained between the elongated member and the wall of the immediately facing structure (e.g., a fluid-filled lumen). Utilizing these measurements, the present invention approximates for the physician the shape and size of the structure into which the elongated member is placed. The invention also includes a method for producing three-dimensional images from two-dimensional images.

  • Patent number: 10226368
    Abstract: A delivery system for delivering a prosthesis includes a sheath, a slide shaft having a threaded outer surface, and a handle. The handle includes an internal spring assembly for selectively engaging and disengaging the handle with the threaded outer surface of the slide shaft. The internal spring assembly includes at least one spring arm, a head coupled to the spring arm and having a circumferentially rounded threaded inner surface, and a ring slidably disposed over the spring arm. When the ring is in a first longitudinal position, the threaded inner surface of the head is spaced apart from the threaded outer surface of the slide shaft. When the ring is in a second longitudinal position, the threaded inner surface of the head is threadedly engaged with the threaded outer surface of the slide shaft. The handle may include a resilient cover to provide the internal spring assembly with a biased or nominal operational position.

  • Patent number: RE47513
    Abstract: A vapor hydrated packaged catheter assembly and method of manufacturing and distributing same includes a gas impermeable package housing a catheter within a catheter-receiving cavity. The catheter assembly has a hydrophilic coating applied to at least a portion of the outer surface of a catheter tube or shaft which may be surrounded by a sleeve to provide a no-touch, sure grip feature. The catheter assembly is disposed within the catheter receiving cavity of the package together with a limited amount of a vapor donating liquid provided as a source of vapor to activate the hydrophilic coating. The amount of vapor donating liquid is less than the amount that would otherwise be sufficient to cause a spill hazard. It may be loose liquid as a desired percentage of the volume of a tube-receiving portion of the catheter receiving cavity of the package, or it may be contained in a liquid sequestering element.
