Publication number: 20210378858Abstract: An adjustably positioned foam chin support maintains the chin in a position precluding or minimizing upper airway obstruction. The chin support is seated within a garment with a portion of the support extending above the garment neck for engaging the user's chin. A garment neckband includes tangentially extending tension cords. Each cord extends through an opening in a front panel of the garment. The ends of the cords are pulled to tension the neckband against the back of the user's neck and apply upward compressive force to position the chin support. A cord lock fixes the tension of the cords. A pair of pouches is affixed to the interior of the garment at the mid-clavicular lines, spaced below the cord openings. The lower corners of the chin support are seated in the pouches.Type: ApplicationFiled: June 7, 2021Publication date: December 9, 2021Inventor: William F. Urmey

Patent number: 9320872Abstract: A catheter positioning system includes a catheter needle assembly comprising a catheter having a permanent hub and a needle carried in the catheter lumen. A releasable clamp is used to compress the catheter against the needle to prevent axial movement of one relative to the other. The clamp is periodically released after being moved a short distance toward the target vessel or nerve and is repositioned a short distance from the skin entry point to further advance the catheter needle assembly. The clamp is configured to be removed from the catheter by movement in a direction other than along the longitudinal axis of the catheter while the catheter hub remains in place. After successful placement of the catheter, the clamp may be snapped apart or opened along a hinge without moving the catheter from its final position.Type: GrantFiled: October 11, 2012Date of Patent: April 26, 2016Inventor: William F.

Patent number: 8571666Abstract: A processor implemented nerve stimulation system for regional anesthesia administration varies pulse width as a programmed function of applied current or varies applied current as a function of adjusted pulse width. The system also provides a waveform of repeating cycles of different pulse width components separated within the waveform frequency and which may be simultaneously attenuated as a function of applied current within an attenuation range. Among possible functional relationships between pulse width and applied current within an attenuation range is the exponential reduction of pulse width as a function of applied current.Type: GrantFiled: July 31, 2006Date of Patent: October 29, 2013Inventor: William F.

Patent number: 7918802Abstract: A target nerve or nerve plexus registration point is located utilizing a nerve stimulator needle positioned in a bore of a carrier. The carrier is configured with an electrically nonconductive smooth curved surface at a distal end of the bore. The needle tip is fixed in an operative cutaneous electrode position and the smooth curved surface of the carrier is forced against and compresses the epidermis, corium and subcutaneous tissue and traverses cutaneous surfaces to locate a target nerve or nerve plexus without physical penetration by the needle tip. The needle is then inserted at the located point, with or without the needle path being guided by the bore. In another embodiment, a subcutaneous portion of carrier is introduced and is pivoted about its introduction point to locate the target nerve.Type: GrantFiled: July 23, 2007Date of Patent: April 5, 2011Inventor: William F. Urmey

Patent number: 7699809Abstract: A system for positioning a catheter includes a nerve stimulator needle carried within the lumen of the catheter. A microelectrode is configured as a needle tip precisely protruding beyond a tapered distal end of the catheter. The catheter and needle are fixed against axial movement relative to one another to maintain the precise configuration of the microelectrode needle tip conductive surface by a releasable clamp which is grasped by the practitioner to compress the catheter lumen against the needle without permanent deformation of the needle shaft while simultaneously advancing the needle and the catheter toward a target nerve.Type: GrantFiled: December 14, 2007Date of Patent: April 20, 2010Inventor: William F.

Patent number: 6533732Abstract: A target nerve or nerve plexus registration point is percutaneously located using a cutaneous nerve stimulator electrode to elicit response. The electrode includes a tip at the end of a coaxial cylindrical body. A central bore extends through the electrode and carries a nerve stimulator needle. The needle is inserted at the located registration point with the needle path being mechanically guided by the bore, thereby avoiding errant needle passes. A peripheral flange of the body serves as a depth guide in assuring appropriate depression of epidural layers for electrical conductivity and for fixation of the nerve. A nerve stimulator current generator supplies both the percutaneous electrode and the nerve stimulator needle and includes multiple outputs as well as base and variable current setting levels as appropriate for each aspect of the technique and for the specific nerve or nerve plexuses being treated.Type: GrantFiled: February 1, 2001Date of Patent: March 18, 2003Inventor: William F.

Patent number: 5846226Abstract: A spinal-epidural administration set includes a spinal needle having a hub and an increased diameter zone extending axially from the hub toward a distal tip. Equidistantly spaced teeth project radially from the zone. The spinal needle is inserted through a hub of an epidural needle whose distal end is positioned within an epidural space. The epidural needle hub includes a throat having a keyway formed of pair of opposed flanges spaced apart a distance sufficient to provide channels for the teeth to pass into a lumen of the epidural needle. When the tip of the spinal needle penetrates the dural membrane, the spinal needle is rotated to engage axially spaced adjacent teeth between the flanges, axially locking the spinal needle. A syringe may then be attached to the spinal needle hub. In order to provide additional extension of the spinal needle through the dural membrane without advancing the epidural needle in the epidural space, the epidural needle hub includes a removable barrel.Type: GrantFiled: May 12, 1997Date of Patent: December 8, 1998Inventor: William F.
