949 results about "Anesthetic" patented technology

An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia ⁠— ⁠in other words, to result in a temporary loss of sensation or awareness. They may be divided into two broad classes: general anesthetics, which result in a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body without necessarily affecting consciousness.

Surgical instrument having fluid actuated opposing jaws

A surgical stapling and severing instrument enables minimally invasive surgical procedures by having upper and lower jaws (i.e., anvil and staple channel) that are positioned with an elongate shaft and handle through surgical openings, and in particular through a cannula of a trocar. A pair of fluid actuator bladders (lift bags) are positioned in the staple channel beneath a proximally projecting lever tray so that transfer of fluid from the handle causes closing and clamping of the anvil. The bi-directional fluid control may be mechanically produced at the handle or by activating an electroactive polymer actuator. Once firing is sensed, an EAP plunger in a medical substance syringe inserted into the elongate shaft is activated to dispense a medical substance (e.g., anesthetics, adhesives, cauterizing substances, antibiotics, etc.) and is guided along a firing bar to a cutting surface of an E-beam placing the substance on tissue as severed.

Apparatus for applying energy to biological tissue including the use of tumescent tissue compression

An electrode catheter is introduced into a hollow anatomical structure, such as a vein, and is positioned at a treatment site within the structure. Tumescent fluid is injected into the tissue surrounding the treatment site to produce tumescence of the surrounding tissue which then compresses the vein. The solution may include an anesthetic, and may further include a vasoconstrictive drug that shrinks blood vessels. The tumescent swelling in the surrounding tissue causes the hollow anatomical structure to become compressed, thereby exsanguinating the treatment site. Energy is applied by an electrode catheter in apposition with the vein wall to create a heating effect. The heating effect causes the hollow anatomical structure to become molded and durably assume the compressed dimensions caused by the tumescent technique. The electrode catheter can be moved within the structure so as to apply energy to a large section of the hollow anatomic structure. In a further aspect, the location of the electrodes is determined by impedance monitoring. Also, temperature sensors at the treatment site are averaged to determine the site temperature.

Controlled-release nano-diffusion delivery systems for cosmetic and pharmaceutical compositions

The present invention discloses the utilization of zeolites for controlled-release of cosmetic and pharmaceutical compositions by nano-diffusion technology. The treatment and protection of skin surface requires that certain compositions be delivered to the skin surface and allowed to remain on the skin surface for as long as possible before such ingredients are absorbed into deeper layers of skin and carried into the bloodstream. Zeolites do not absorb into the skin, which is useful for topical delivery of cosmetic and pharmaceutical compositions, for example antiaging, anti-wrinkle, antioxidants, skin whitening, acne treatment, rosacea treatment, sun screens, UV blocks, anesthetics, skin soothers, anti-irritants, anti-inflammatory agents, vitamins, hormones, and such that are electronically attached to the outer surfaces of such zeolites and are released to the outer surface of skin by a diffusion-controlled thermodynamic process.

Methods and kits for maxillary dental anesthesia by means of a nasal deliverable anesthetic

InactiveUS6413499B1Less fearLess anxietyBiocideCosmetic preparationsNostrilNasal cavity
Methods and systems for anesthetizing a portion or all of a patient's maxillary dental arch using a nasal delivered anesthetizing composition. The process generates anesthesia sufficient for facilitation of operative dentistry, endodontics, periodontics or oral surgery for teeth of the maxillary arch. The dental nasal spray process consists of inserting one or more dispensing devices through the patient's nostril and delivering metered dosages of anesthetic solution or gel into the nasal cavity. The process may utilize a single solution which is a mixture of anesthetic agents, vasoconstricting agents and other physiological inert agents or two separate solutions, wherein one solution contains the vasoconstricting agents and the other solution contains the anesthetic agents. Anesthetic diffusion through the thin walls of the nasal cavity allows for the blocking of nerve impulses originating from the maxillary dentition and surrounding tissues. Anesthesia of specific oral regions such as right versus left sides of the dental arch, anterior versus posterior teeth, and soft tissue anesthesia may be controlled through modification of the dosage volume and the selection of right or left nostril insertion and agent delivery.

Systems for treatment of nasal tissue

Systems for the treatment of nasal tissue, particularly the nasal turbinates, are described. One method for reducing the size of the inferior nasal turbinate is to apply ultrasound energy to the tissue regions beneath the surface of the turbinate tissue. One instrument may be used to deliver ultrasound energy and provide an infusion or injection of a fluid directly into the turbinate being treated, e.g., to bulk up the size of the turbinate to ensure that the ultrasound energy is properly delivered directly into the intended turbinate tissue. Fluids containing anesthetics, fluids infused with analgesics, etc. may be used for pain management while other medications, such as non-steroidal drugs, steroidal drugs, anti-inflammatory drugs, anti-histamines, anti-bacterial drugs, etc., can also be used. Such assemblies can also be utilized with other instruments as a system. For example, such a probe can be used with nasal speculums or imaging instrument in treating tissue.
