Edwin L. Adair has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: An apparatus and method is provided for initially anesthesizing the vas deferens of a male patient and then cauterizing the vas deferens to thereby permanently sterilize the male. In one embodiment, the apparatus includes a container to house an anesthetic fluid and which is removably attached to a first electrode. The first electrode includes a hollow needle having a tip formed at one end. The apparatus further includes a second electrode having a conducting probe with a distal end and which is slidably insertable through the hollow needle.In operation, the needle is inserted through the scrotum wall and the tip positioned within the vas deferens. The anesthetic is forceably moved from the container through the hollow needle to desensitize the vas deferens. The container is removed from the first electrode and the second electrode is inserted into the first electrode. The distal end extends beyond the tip of the hollow needle and is positioned within the vas deferens.
Abstract: A drainage device for attachment to a portion of the skin of an individual is provided. The device comprises a flange which sealingly engages the skin and has an opening therein to overlie a wound in the skin tissue. A ring member having a channel formed therein is mounted on a side of the flange opposite that side of the flange engaging the skin. A locking clip is connected to the ring member and extends laterally between portions thereof. A drainage strip is releasably held in the locking clip and inserted into the wound so that drainage of the wound occurs. A removable cover member grippingly engages the outer wall of the ring member to prevent the drainage from escaping the confines of the device.
Abstract: Ostomy bag securing apparatus, and method of applying same, characterized by implanting a plurality of small powerful permanent bar magnets through skin punctures to positions beneath the skin and surrounding a stoma, without surgical cutting of the skin, and applying a magnetically permeable collar, having a bag removeably affixed thereto, on the outer surface of the skin, concentric with the magnets. Alternatively, the implanted bars may be magnetically permeable, but not permanently magnetized, and permanently magnetized bars disposed on the collar which latter may be formed of non-magnetic material.
Abstract: Birth control apparatus and method characterized by a ring, adapted to be inserted through the male urethra, and placed in the bladder neck sphincter to maintain same open. During ejaculation, seminal fluid is discharged into the bladder and voided therefrom at a later time. In a preferred form, the ring is contracted to sufficiently small size to permit it to be inserted through the urethra and, after being placed in the sphincter, expanded to larger size, locking same against unauthorized movement therefrom.
Abstract: A method for sealing together the ends of concentrically arranged tubes of plastic material to make a double-walled tube which comprises inserting the assembled ends into a mold means conforming substantially in size to the outer periphery of the finished tube and applying heat to seal the tube ends together. Preferably, the tubes during heating are arranged concentrically with the end of one tube extending beyond the end of the other tube and if the materials of the two tubes have different melting points, the tube having the lower melting point extends slightly beyond the other tube. Preferably, a rod of material having good heat conductivity and a melting point higher than that of the plastic tubes is positioned inside the inner tube with its end slightly below the sealing area. The tube edges can be sealed together leaving an opening in the finished end or the finished end sealed completely over.
Abstract: Tube adapted to be disposed within a ureter for drainage from a kidney to the bladder, characterized by a cord or suture member secured to its lower end and lying along same to a point of securement, preventing movement of the tube into the bladder.
Abstract: Catheter of the telescope tube, expandable wing type, characterized by the provision of alternative forms of means for preventing outward leakage from between the tubes, the leakage preventing means also serving the additional purpose of retaining the wings in expanded position. Alternative forms of tube distal ends are disclosed including one form for removing clots from blood vessels. Also, a stiff trochar rod may be employed with various forms of seals and the tube distal ends.
