Abstract: The present invention relates to a closed system and method for selectively infusing anesthetics into a peripheral nerve or plexus. A method of providing long term pain management is disclosed herein. In the method, a catheter is surgically implanted to create an infusion site at a peripheral neural structure. An implantable pump and reservoir are surgically implanted in subcutaneous tissue. The pump is then operated to deliver a predetermined dosage of medication through the catheter into the infusion site, whereby pain management is provided.

Abstract: Inhalant anesthetics are developed with a number of properties including rapid onset and recovery, controllability, and, ideally, a broad safety profile. The efficacy of these agents is measured by their ability to create anesthesia within the framework of the other desirable properties. The instant invention focuses on the dosage level where analgesia occurs but amnesia or lack of consciousness does not. In addition to identifying the dosage level where pain is sharply reduced or eliminated but awareness remains, a delivery system for safe and effective delivery of the agent is described.

Abstract: A medication delivery device is disclosed having a hollow drill bit with a lateral opening that is adjacent to a beveled or sharpened tip of a hypodermic needle. The lateral opening, which can be a slot or a notch or hole, is located a distance proximal of the sharpened tip that is not less than the thickness of the tissue to be penetrated. This structure allows the hollow drill to penetrate bone and/or other hard tissues without being completely clogged by drilling debris. After drilling into the bone or hard tissue, medication can be delivered through the bore of the hollow drill. The lateral opening provides a clog-free passage for injection of the medication.

Abstract: Apparatus and methods for the power and computer assisted injection of local anesthesia into a patient in which anesthesia pressure is automatically monitored as an input to the computer, in which the patient is able at any time to order the automatic reduction of anesthetic pressure, in which a single pole switch is the only control input to the computer required of the doctor administering the injection, and/or in which the flow rate of anesthesia from the needle continuously increases with time over a substantial portion of the injection.

Cleansing the knee joint and, preferably, covering it with a surgical drape; 2. Applying the first local anesthesia superficially to the joint to create a wheat; 3. Injecting through the wheal the second local anesthesia into the knee joint; and 4. Performing the lavage on the knee joint without removing the second needle from the knee joint.

Abstract: A method of epidural surgery is provided that improves visibility in the epidural space of a patient for more effectively conducting therapeutic surgery therein. The method includes the steps of distending a portion of the epidural space of a patient by filling the portion of the epidural space with a fluid supplied from a catheter and positioning a portion of an optical scope in the distended portion of the epidural space by inserting the optical scope through the same catheter that supplies the distending fluid to thereby provide a visual image of the epidural space.

Abstract: A drug delivery system provides sustained-release delivery of therapeutic biologically active compounds administered epidurally. In the preferred embodiment the biologically active compound is an opioid, which is encapsulated within the non-concentric internal aqueous chambers or bilayers of multivesicular liposomes. The opioid is released over an extended period of time when the liposomes are introduced epidurally as a single dose for sustained analgesia.

Abstract: A delivery method and implantable apparatus that allows for controlled, enhanced and (pre)-programmable administration of a biologically active agent into the spinal structures and/or the brain via the epidural space of a mammal, particularly of a human being and including a feedback regulated delivery method and apparatus specifically in the treatment of neurological diseases and chronic pain.

Abstract: A microbicidal organic polymer material for use in manufacturing of contact lenses, catheters, condoms, surgical sutures and gloves, medical examination devices and similar uses is provided by polymers to which is tightly adsorbed a disinfectant organic dye. Many polymers such as polyvinyl chloride and acrylic polymers show exceptional avidity for a number of microbicides, of acidic, basic, aromatic and/or hydrophobic character such as methylene blue and gentian violet. Consequently, devices constructed of these polymeric materials release no free dye to an aqueous solution. The material is generally a natural or synthetic polymer that releases no particles or fines into wounds or body orifices. Presence of adsorbed disinfectant organic dye allows the polymer to inhibit microbial growth in a number of different situations. Several common microbes are killed by being incubated in the present of an embodiment of the invention that contains a combination of methylene blue and gentian violet.

Abstract: A method for treating stroke patients includes inducing mild or moderate hypothermia in a patient using one or more closed loop heat exchange catheters positioned either in the patient's central venous system, carotid artery or both when the patient's body temperature and/or brain temperature are above predetermined thresholds. Additional steps for treating and managing a stroke patient can also be undertaken, e.g., infusing paralytics, infusing neuro-protectants, infusing anti-clot and/or clot lysis medications, performing neuro-protection procedures, performing non-catheter-based hypothermia, performing angioplasty, deploying stent, removing clot(s), maintaining a predetermined ICP level such as draining CSF, and/or ventilating the patient.

Abstract: A system for delivering an anaesthetic-containing fluid to a desired site in a patient includes a catheter for channeling the fluid into a unitary portal penetrating a body. A pump capable of delivering fluid at a constant flow rate is dimensioned to retain sufficient fluid for at least a one-day delivery and is adapted to permit being affixed to the body to permit portability. A fluid line, such as tubing, transports fluid from the pump to the catheter. A kit further includes an introducer needle dimensioned to permit the catheter to pass therethrough. A method of relieving pain at a surgical site postoperatively over an extended period of time includes the steps of inserting an anaesthetic-containing fluid into a pump interior having a capacity sufficient for at least a two-day delivery.

Abstract: A hypodermic needle device for administration of anesthesia to a patient's epidural space comprising a hypodermic needle having a barrel portion with opposed distal and proximal ends, a hub assembly located at the proximal end of the barrel portion of the needle, through which instruments such as a rigid stylet, or a flexible catheter having a pre-affixed connector, may be introduced into the needle, and a slot formed axially along the length of the needle from the distal end through the hub at the proximal end of the needle. The slot has a minimum width dimension not greater than the outer diameter of a stylet or epidural catheter such that during location of the epidural space, and placement of a catheter in the epidural space, the stylet and catheter will not come out of the needle, yet the needle may be easily removed from the catheter once the catheter is in place, by pulling the catheter through the slot in the needle.

Abstract: A catheter system having an epidural needle, an electrically conductive stimulation wire attached to the needle, a multi-purpose connector, which is adapted to connect to intravenous tubing for supplying local anesthesia, and an epidural catheter for supplying regional anesthesia. When the connector and needle are connected to each other, an operator can insert the needle into a patient with the needle's distal end within the nerve sheath and proximate to the nerve plexus. A voltage is applied via the wire to determine correct positioning. Then, the operator can slide the catheter through the connector and needle until the catheter's distal end is protruding out of the needle's distal end and into the nerve sheath, proximate to the nerve plexus. Then, the needle (and its associated wire) and the connector (and its associated tubing) are slidably removed from the catheter, and the catheter may be left in place.
