  • Patent number: 10335312
    Abstract: Devices and methods for removing an intravaginal drug delivery ring are shown and described. In one embodiment, the device is an integral one-piece moisture impermeable structure that includes a closed end finger cot and a substantially rigid hook. Typically, the closed end finger cot includes a finger opening, a compression band, and an expandable sleeve. In some examples, the distal end of the hook is aligned substantially parallel to an axis of the finger cot to properly position the user's finger with the intravaginal drug delivery ring in the vaginal canal. The result is devices and methods to improve removal of intravaginal drug delivery rings and similar contraception prevention units.

    Abstract: A detachable vertical cutter for insertion into a cylinder or tube is formed as a single unitary structure. The single blade has a pair of tool attachment end portions and a cutting blade extending in a loop between the attachment ends. The cutting blade is inclined vertically relative to a longitudinal axis of a cylinder or tube into which the attachment ends can slide into. The cutting blade has a cutting edge, a portion of which when extended free of the cylinder or tube will extend a distance greater than the tube outside diameter. The cutting edge when pushed inwardly and pulled outwardly between adjacent vertebrae scrapes and cuts disc material. When retracted the cutting blade deflects into the cylinder or tube for insertion or extraction into or from the disc space.

  • Patent number: 9649128
    Abstract: An adjustable, disposable dermal curette is structured to allow a user-practitioner to ergonomically grip a handle and manipulate an adjustable slider with a digit of their hand in order to change the diameter size of the flexible blade formed in an adjustable loop to the useful range of diameter sizes required. The user-practitioner can lock and unlock the slider in place quickly without the need to interrupt their procedure. The adjustable curette solves the problem of requiring multiple curette loop sizes for a procedure and results in improved quality of care and a savings of time and healthcare dollars.

  • Patent number: 6949108
    Abstract: The invention is a curette that includes a tip and shaft that detachably join together to form a working tool member. The shaft has a threaded receiving end that is sized to receive a mating end of the tip. The mating, or proximal, end of the tip includes a corresponding threaded section and a smaller-diameter outwardly extending elongated section that is flattened on one or more sides. To attach the tip to the shaft, a user partially fills the receiving end of the shaft with epoxy. The user then inserts the mating end of the tip into the receiving end of the shaft, such that the epoxy surrounds the elongated section of the mating end and fills or partially fills the threads. The user then screws the tip and shaft together, to interlock, or self-lock, the threads. When the epoxy thereafter hardens, the tip is firmly held against rotation relative to the shaft both by the epoxied and interlocked threads and the flattened-sided section that, because of its shape, resists rotation within the hardened epoxy.

The slot contains a blade for cutting the side branches and electrocauterizing plates for sealing the cut ends of the side branches. An opening may be provided for application of a ligation device to the side branch. The apparatus may be inserted into an incision in a patient's body and advanced along the length of a vessel to endoscopically dissect, ligate and transect the side branches to harvest the main trunk of the vessel to support subsequent surgical procedures.

  • Patent number: 6074405
    Abstract: The improved medical instrument is adapted to remove obstructions from ear canals, nostrils and endotracheal tube airways. It includes an elongated handle with an elongated hollow tube connected to the front end thereof and an elongated flexible wire extending from the front end of the tube. The front end of the wire is curved to form a scoop for removing obstructions from a lumen. In one embodiment the wire and tube are removable as a replaceable unit from the front end of the handle. In another embodiment the handle has a central cavity therein communicating with the cavity in the tube and through both of which the wire extends. The wire is connected to a spring which extends out of the handle. The spring biases the wire into the tube. When the wire is manually depressed the front end of the wire extends out of tube and curves into the desired scoop configuration. The instrument can include a light which is switched on when the wire extends out of the tube and which is used to light the lumen.

  • Patent number: 5968062
    Abstract: A cutting device for the cutting and reduction of matter from a surgical site having a cutting head having an entry tip and a cutting blade positioned on opposed leading edges of a window formed through the interior of the cutting head. The window includes angled walls extending from each cutting blade along the circumference of the window. The cutting head is attached to a shaft for mounting the cutting device to a rotary surgical drill. The matter is removed and further reduced as the cutting head is rotated at the surgical site. The main shaft also includes depth markings for identifying the depth of the device in the surgical site. The geometry of the cutting head and entry tip can be varied for particular surgical procedures.

  • Patent number: 5836958
    Abstract: A curette having a variably angled handle includes a curette member which has a disc shaped end. The disc shaped end has a hole through its center and a series of discrete angular graduations on its edge. The disc shaped end is retained via a pin in a recess in the proximal end of a handle. The handle includes an axial bore through which a shaft extends into selective contact with the graduations on the disc shaped end of the curette member. The curette may be angularly positioned relative to the handle if the shaft is selectively disengaged from its contact with the graduations of the disc shaped end of the curette member, but not once the shaft has engaged the graduations. The shaft may be selectively engaged by a variety of different ways, including spring biasing, threading and having a selectively extendable handle.

  • Patent number: 5752967
    Abstract: A corneal surface marker is used to improve centration of surgical laser instrumention and repositioning of a corneal cap or flap in corneal surgery, particularly lamellar corneal surgery. The marker has inner and outer concentric rings with marking radials extending off the rings to provide adequate reference points for marking indicia to be placed on the corneal surface. The method involves positioning a patient's head with direct light thereby fixating and centering the laser instrumentation over the visual axis of the eye, preoperatively marking the corneal surface with a plurality of radial lines spaced about the visual axis, and aligning a reticule of a surgical laser instrument over the radial lines thereby permitting anatomic centration of the instrument over the visual axis for subsequent accurate surgical reshaping of the cornea.

  • Patent number: 5649942
    Abstract: A disposable comedone extractor for use in dermatologic surgery fabricated of a synthetic resin reinforced with natural or synthetic fibers. It has been found that the use of a reinforced synthetic resin ensures that the extractor of the present invention is fully disposable, and thus far less expensive to manufacture and use, as compared to conventional extractors fabricated from metals. In addition, the use of a synthetic resin allows greater control of the flexibility of the extractor as compared to rigid metal extractors.
