Patent number: 8500678Abstract: A method and an apparatus for applying an anesthetic include an elongated tubular housing having an upper end, a substantially hollow interior, and a lower end having an injection needle extending therefrom. A first chamber is formed within the housing interior for holding an anesthetic cartridge therein. A second chamber receives a cannister containing an endothermic gas that rapidly absorbs heat when released to the atmosphere. The cartridge is penetrated by a plunger that forces the anesthetic through the injection needle. A depressible trigger propels the gas through an outlet nozzle that is oriented to project a stream of gas along a delivery axis that intersects a delivery axis of the needle; therefore, the gas and anesthetic can be successively delivered to an injection site with minimal repositioning of the housing. Accordingly, a dental practitioner can initially disperse the endothermic gas onto the injection site to minimize any pain and discomfort associated with an injection.Type: GrantFiled: September 11, 2009Date of Patent: August 6, 2013Inventor: Jacob Leibovici

Patent number: 8475340Abstract: Patients having exercise limiting conditions and those at risk of developing such conditions are exposed to a regimen of hypoxic conditions that simulate various altitude conditions. The exposure is of a temporary nature, being from a few hours to most of a day or night in any one day and repeated on a personally worked out regimen of from a series of consecutive days to a regular number of “on” and “off” days, to a random number of days. An alternate regimen is such exposure for a few minutes at a time followed by normoxic rest period of a few minutes, with the cycle repeated multiple times over the course of a treatment session. The conditioning treatment strengthens the cardiac tissue and skeletal muscle and the results extend beyond the treatment periods whereby the patient's condition is substantially improved.Type: GrantFiled: January 29, 2010Date of Patent: July 2, 2013Assignee: Montefiore Medical CenterInventor: Simon Maybaum

Patent number: 8469919Abstract: Apparatus and methods for uniformly distributing coolant within a cryo-ablation device. A nozzle apparatus includes a tubular member having a plurality of angled apertures that induce swirling of coolant streams dispersed through the angled apertures.
