  • Patent number: 10813663
    Abstract: A device suitable for use in a body lumen and comprises an elongated control member having a distal and a proximal end, and a radially expansible member disposed at or near the distal end and adapted for collection and/or shearing of matter (i.e. thrombus) from a wall of the body lumen (i.e. a vein or an artery). The radially expansible member has a proximal end and a distal end and is adjustable between a contracted orientation and an expanded orientation. The elongated control member comprising a proximal arm connected at or adjacent to the proximal end of the radially expansible member and a distal arm connected at or adjacent to the distal end of the radially expansible member such that movement of one arm relative to the other arm effects adjustment of the diameter or radial strength of the radially expansible member. The device comprises a control mechanism operatively connected to both arms and adapted to provide resistance to the movement of one arm relative to the other.

  • Patent number: 10786269
    Abstract: A snare and retrieval device including a handle section, a cord section attached to the handle section, and a tip section removably attached to the cord section and spaced away from the handle section. Such a tip section is selectively detachable from the cord section while the cord section remains attached to the handle section. The tip section is detachable thereby allowing a surgeon to easily change the snare tip to a bigger or smaller size as necessary during the operation. A user can use one cord section for both removal of a polyp followed by retrieval of the polyp for further examination. This is done by changing the snare member to a retrieval member. The detachability of the tip section allows the device to replace at least two or more separate snare and retrieval devices, thereby reducing cost and time during the operation.

  • Patent number: 10786661
    Abstract: A dilation balloon is wrapped in one or more patterns with a wire or braided material having diamond abrasive or other abrasive material bonded thereto. The wire or braided material is vibrated in one or more ways to enhance the cutting action of the wire abrasive. The wire abrasive may be vibrated using high, low, or even ultrasonic waves transmitted to the wire abrasive via local or remote methods. Alternatively, the dilation balloon may be dilated with a contrast media that exhibits a high absorption to laser light. The contrast material is lazed with a laser fiber or fibers inserted into the balloon interior, creating a substantial shockwave that vibrates the balloon and assists in the cracking or abrading of the surrounding plaque in contact with the dilation balloon. The cutting balloon may employ the abrasive coated wires described above or cutting blades.

  • Patent number: 10786656
    Abstract: Devices and methods for recanalization of occluded body vessels using novel guidewires. A novel double-sided guidewire comprises a cross-section tapering from a more rigid middle section towards more flexible head sections. A first head of the guidewire is inserted into the occluded body vessel in a retrograde direction to traverse an occlusion. The guidewire is further advanced in the retrograde direction such that the first head and a portion of the middle section are retrieved from the body, thereby positioning the remainder of the guidewire traversing the occlusion in an antegrade direction and allowing for over the wire recanalization techniques in the antegrade direction.

  • Patent number: 10779840
    Abstract: A hemostatic device can inflate an inflatable portion without using a separate dedicated instrument, can reduce an unpleasant feeling of a wearer, and can prevent a site where bleeding is to be stopped from being unintentionally and unnecessarily compressed. The hemostatic device has a band for being wrapped around a limb, an inflatable portion that is inflated by injecting gas, an injection part that is configured to inject gas into the inflatable portion, and a flow route that permits communication between the inflatable portion and the injection part. The flow route includes a backflow preventer which prevents gas from flowing out to the injection part from the inflatable portion. The injection part is located on the band, and includes holes which penetrate the injection part in a direction intersecting a perpendicular line to a region of the band where the injection part is located.

  • Patent number: 10772653
    Abstract: Disclosed is an infinitely adjustable depth stop for a laparascopic instrument having a shaft, the depth stop including a first component having a first annular space adapted to allow the shaft to be fitted therethrough. The first annular space has a reducible diameter and an interference surface against which the shaft may be fitted. Upon reduction of the reducible diameter, the interference surface frictionally engages the shaft to arrest relative movement of the depth stop along the shaft. The frictional engagement may be along a curve, a spiral curve, or an area. Means are also provided to reopen the reducible diameter to release the depth stop.
