Publication number: 20190290287Abstract: A compressive brace for intraarticular needle procedures that provides constant radial compression. One embodiment comprises a non-pneumatic releasable compressive planar device or tubular sleeve, a method to apply tension to the device or sleeve comprising a non-stretchable material or stretchable elastomeric material with fasteners or external compression straps or both resulting in fluid displacement and increased intraarticular fluid pressure, a design that displaces fluid within the joint to low pressure areas to be readily accessible by needle or catheter via specific anatomic portals so that the joint can be completely aspirated, tension and pressure can be released so that fluid can be easily removed or injected into the joint, and integration of the device into arthrocentesis, surgical, diagnostic, and joint therapy kits. Some embodiments define a window or aperture to allow pooling of fluid and to introduce needles and catheters.Type: ApplicationFiled: July 3, 2017Publication date: September 26, 2019Inventors: Wilmer L Sibbitt, Jr., Philip Arthur Band, Randy Robert Sibbitt

Publication number: 20190247567Abstract: Percutaneous musculoskeletal lavage devices, and procedures for simultaneous therapeutic and diagnostic purposes, performed with a needle or catheter and various combinations of a syringe, reciprocating syringe, stop-cock, check valves, depth indicator, compressive sleeve or brace, and specialty catheters, provided individually or in a kit. The lavage fluid can be analyzed for factors of medical interest and used to determine personalized treatment, and has intrinsic medical benefit by virtue of clearing the tissues of noxious substances in an enhanced fashion.Type: ApplicationFiled: February 12, 2019Publication date: August 15, 2019Inventors: Wilmer L Sibbitt, Jr., Philip Arthur Band, Randy Robert Sibbitt

Patent number: 8920442Abstract: Tissue eversion apparatuses and methods suitable for use, as examples, with vascular closure devices. The tissue eversion apparatuses comprise a tissue engaging element, disposed within a delivery sheath. The delivery sheath protects the tissue engaging element and the surrounding tissue during use. The tissue engaging element can extend from the sheath and engage the tissue near an aperture in a tissue wall. Motion of the tissue engaging element away from the tissue can urge the tissue wall near the aperture to evert from the tissue wall, allowing, as examples, aperture closure apparatuses and methods to be conveniently employed.Type: GrantFiled: August 23, 2006Date of Patent: December 30, 2014Assignee: Abbott Vascular Inc.Inventors: Wilmer L. Sibbitt, Jr., Randy R. Sibbitt

Patent number: 8758397Abstract: A vascular closure device comprising a retrievable sheath-delivered contractible, clip device with structural radial or terminal members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure clips, this device is delivered on the outside rather than the inside of sheath. Closure of the tissue opening can be effected by the feet of the clip engaging the puncture, aperture, or wound edges and memory characteristics of the device cause a contraction of the members, bringing the members into apposition and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.Type: GrantFiled: August 23, 2006Date of Patent: June 24, 2014Assignee: Abbott Vascular Inc.Inventors: Wilmer L. Sibbitt, Jr., Randy R. Sibbitt

Patent number: 8048108Abstract: A vascular closure device comprised of a sheath-delivered expandable, umbrella-like device with structural radial members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure umbrella-type devices that effect closure by opening of the umbrella to cover an opening, the present invention effects closure of the aperture with closure of the umbrella. The closure can be maintained by a retainer lock that slides down the members, causing contraction, bringing the members into a compressed configuration (e.g., a parallel orientation of linear members) and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.Type: GrantFiled: February 4, 2009Date of Patent: November 1, 2011Assignee: Abbott Vascular Inc.Inventors: Wilmer L. Sibbitt, Jr., Randy R. Sibbitt

Patent number: 7967793Abstract: A reciprocating syringe that can be used in connection with existing syringe barrels and fittings. Some embodiments comprise a frame, adapted to retain two existing syringe barrels. The frame can accommodate fittings on one or both barrels. The invention also provides a plunger complex, comprising two plungers, each adapted for use with one of the syringe barrels. The two plungers are coupled such that pushing of each plunger into its barrel causes the other plunger to pull outwards relative to its barrel. The two plungers can be coupled by a flexible line attached to one plunger, routed from the plunger out of the corresponding barrel into the other barrel, and attached to the other plunger. The invention contemplates various frame configurations to accommodate desired line and pulley performance characteristics. Other embodiments comprise a frame adapted to retain an existing syringe barrel, and an auxiliary actuator mounted with the frame.Type: GrantFiled: January 20, 2006Date of Patent: June 28, 2011Assignee: Avance Medical Devices, Inc.Inventors: Wilmer L. Sibbitt, Jr., Randy R. Sibbitt

Publication number: 20110087173Abstract: The present invention provides automatic syringes that can be held with one hand in a pencil-grip in which the fingers (thumb or index finger) operate a forwardly based valve that along with selection of needle diameter and length, control the ingress or egress of fluid from the automatic syringe. These finger-controlled one-handed automatic syringes can be used in image-directed procedures such as ultrasound (sonography)-directed procedures in which the ultrasound probe is controlled with one hand and the automatic syringe with the other, although many other applications are readily apparent to those skilled in the art including biopsy, epidural injections, administration of anesthesia, and detection of blood vessels and body cavities as well as other applications.Type: ApplicationFiled: October 7, 2010Publication date: April 14, 2011Inventors: Wilmer L Sibbitt, JR., Randy R.

Patent number: 4090012Abstract: Electrochemical heat engines produce electrochemical work, and mechanical motion is limited to valve and switching actions as the heat-to-work cycles are performed. The electrochemical cells of said heat engines use molten or solid electrolytes at high temperatures. One or more reactions in the cycle will generate a gas at high temperature which can be condensed at a lower temperature with later return of the condensate to electrochemical cells. Sodium, potassium, and cesium are used as the working gases for high temperature cells (above 600 K) with halogen gases or volatile halides being used at lower temperature. Carbonates and halides are used as molten electrolytes and the solid electrolyte in these melts can also be used as a cell separator.Type: GrantFiled: May 5, 1977Date of Patent: May 16, 1978Assignee: The United States of America as represented by the United States Department of EnergyInventors: Guy R.
