Publication number: 20130085381Abstract: An infusion catheter assembly has the ability to infinitely titrate the length of a porous fluid distribution section in situ. The infusion catheter assembly thereby provides a length of infusion that can be infinitely varied over a prescribed range, to control the effective infusion length and the rate of infusion. Using the infusion catheter assembly, a physician has the capability to treat only the length of the vessel desired, thereby preventing excessive drug/patient exposures. The porous fluid distribution section can include an array of spaced apart apertures that vary in size and/or density along the length of the porous fluid distribution section, such that the flow rate remains essentially constant for a given inlet pressure independent of the effective infusion length.Type: ApplicationFiled: August 1, 2012Publication date: April 4, 2013Applicant: Venous Therapy, Inc.Inventors: Anthony J.

Publication number: 20080183151Abstract: An epidural needle has an elongate tube and a hub with a proximal end, a distal end, an open passageway having an inside diameter, and a cavity disposed between the proximal end and distal end. The hub is attached to the elongate tube so that a hollow bore of the elongate tube is in fluid communication and substantial axial alignment with the open passageway. A resilient member defining an opening therethrough is disposed in the cavity and is axially aligned and in fluid communication with the open passageway. The hub has a clamp with a releasable latch disposed about the resilient member. The clamp is selectively movable between an open position wherein the inner diameter of the resilient member is substantially unaffected and a clamp/latch position wherein the clamp causes a strain to the resilient member and thereby reduces the inner diameter of the opening through the resilient member.Type: ApplicationFiled: November 27, 2007Publication date: July 31, 2008Inventors: Ronald W. Marsh, Sean P. Daw

Publication number: 20080119820Abstract: The present invention provides methods for reducing pain in a subject in need of such pain reduction by delivering, e.g., intrathecally or epidurally, a volatile anesthetic such as a halogenated ether compound in an amount effective to reduce pain. Chronic or acute pain may be treated, or the anesthetic may be delivered to the subject to anesthetize the subject prior to a surgery. In certain embodiments, isoflurane, halothane, enflurane, sevoflurane, desflurane, methoxyflurane, xenon, and mixtures thereof may be used. Dosing regimens including a one-time administration, continuous and/or periodic administration are contemplated.Type: ApplicationFiled: September 20, 2007Publication date: May 22, 2008Inventors: Phillip C. Phan, Allen W. Burion

Publication number: 20080108970Abstract: The invention relates to a method and apparatus for controlling drug administration. In order to achieve an easy-to-use and technically reliable control mechanism that can be implemented cost-effectively, input information including patient information and effect level information for at least one type of drug effect to be achieved in a patient is supplied to the control mechanism. Synergetic pharmacodynamic models are utilized to determine, based on the input information, effect-site concentration(s) for at least one drug to be administered. A pharmacokinetic model of each drug may then be utilized to define, based on the effect-site concentration of the drug, a delivery rate for the drug to be administered.Type: ApplicationFiled: November 8, 2006Publication date: May 8, 2008Inventor: Hanna E. Viertio-Oja

Publication number: 20080097387Abstract: A delivery system for dispensing sterile liquids into the oral cavity using a novel pre-angled needle hub assembly attached to a standard anesthetic syringe loaded with a novel cartridge ampule containing a certain liquid solution. This system substantially improves the efficiency of delivering small amounts of sterile fluid into the oral cavity by hypodermic means or by irrigation means using pre-angled needles or cannulas to reach otherwise impossible-to-reach locations within the oral cavity while also providing the ability to dispose of used needles without re-bending and thus complying with federal OSHA, state OSHA, and state regulatory disposal regulations.Type: ApplicationFiled: September 4, 2006Publication date: April 24, 2008Inventor: David M. Spector

Patent number: 7120487Abstract: A catheter system and method is provided for overcoming various problems commonly associated with the application of regional anesthesia. Disclosed herein are several embodiments for providing continuous regional anesthesia. In general, the catheter system includes an epidural catheter, an epidural needle, tubing for optional fluid administration, an attached conductive wire (for connection to a nerve stimulator) and a catheter introducer, which is integrated within the proximal hub of the insulated needle. The embodiments may differ in several ways.Type: GrantFiled: July 18, 2003Date of Patent: October 10, 2006Inventor: David A. Nelson

Patent number: 7014634Abstract: Disclosed is a vapor wand for administering inhalation anesthesia to wild animals. The wand has a fibrous wick that absorbs liquid anesthetic inserted by a syringe through a distal end cap and/or a leur fitting. Holes are spaced around the distal end of the wand so that movement of the air pump handle causes vaporized anesthetic to be dispensed through the holes.Type: GrantFiled: July 26, 2004Date of Patent: March 21, 2006Inventor: David S. Hodgson

Patent number: 6866648Abstract: An objective and reproducible system for, and method of, monitoring and/or controlling the pressure during nerve blockage injection, especially by less experienced personnel, is provided in order to decrease the possibility of intraneuronal injection. More specifically, the present invention employs a pressure sensing and/or limiting device located between an injection device (typically a syringe) and a nerve block needle whereby injection pressure during a nerve block injection can be easily and objectively monitored, thereby allowing the operator to monitor the injection pressure and/or injection speed during a nerve blockage injection procedure and to take appropriate corrective actions if abnormal pressure conditions are observed.Type: GrantFiled: May 28, 2002Date of Patent: March 15, 2005Assignee: Macosta Medical U.S.A., L.L.C.Inventors: Admir Hadzic, Jerry D. Vloka, Sergio Giglioli
