Publication number: 20090035357Abstract: A method of drug delivery utilizes a transdermal device that contains a phase change material and a first material such as a drug, a pharmaceutical, or a medicament mixed with or disposed near the phase change material. The phase change material is one that transitions from solid to liquid form when heated. A second material is disposed, suspended, or held in the solid form of the phase change material. The phase change material changes to a liquid state in response to heat and the second material that is disposed, suspended, or held in the phase change material is released and comes into contact with the first material. Advantageously, such second materials may include substances such as pharmaceuticals that boost or supplement the effect produced by a drug delivered transdermally by the device, or drug antagonists, or nicotine.Type: ApplicationFiled: August 8, 2008Publication date: February 5, 2009Applicant: ARIZANT HEALTHCARE INC.Inventor: Albert Philip Van Duren

Patent number: 7338515Abstract: In a convective system that includes a blower to thermally treat and pressurize air, a convective device to receive and convect the thermally-treated pressurized air, and an air hose to conduct a flow of thermally-treated pressurized air from the blower to an inlet port in the convective device, an interface device is provided to control the flow of air at the interface where the inlet port and an end of the air hose operate to conduct the flow of air out of the air hose into the convective device. The interface device is received at the end of the air hose and operates to support the flow of air out of the end when the end and the inlet port are brought together. The interface device operates to stop, inhibit, or restrict the flow of air out of the end when the end and the inlet port are separated.Type: GrantFiled: April 23, 2002Date of Patent: March 4, 2008Assignee: Arizant Healthcare Inc.Inventors: Albert Philip Van Duren, Allen Hamid Ziaimehr, John Paul Rock, Scott Douglas Augustine, Gary Rabindranath Maharaj, Randall Charles Arnold

Patent number: 7220273Abstract: Airflow provided through an air hose to the inlet port of an inflatable thermal device is controlled by a mechanical device disposed at an end of the air hose that is coupled to the inlet port. In response to coupling the end of the air hose to the inlet port, the mechanical device operates to open the end and permit air to flow through the air hose and the inlet port. In response to decoupling the end of the air hose from the inlet port, the mechanical device operates to block air from flowing through the end of the air hose.Type: GrantFiled: December 17, 2001Date of Patent: May 22, 2007Assignee: Arizant Healthcare Inc.,Inventors: Albert Philip Van Duren, Allen Hamid Ziaimehr, John Paul Rock, Scott Douglas Augustine, Gary Rabindranath Maharaj

Publication number: 20040191301Abstract: A transdermal device contains a phase change material and another material. The transdermal device may also contain a drug, a pharmaceutical, or a medicament mixed with or disposed near the phase change material. The phase change material transitions from solid to liquid form when heated. The other material is disposed, suspended, or held in the phase change material when the phase change material is in its solid form. When heat is applied to the transdermal device, the phase change material changes to a liquid state and the material that is held or suspended in the phase change material is released. Advantageously, such materials may include substances such as pharmaceuticals that boost or supplement the effect produced by a drug delivered transdermally by the device, or drug antagonists.Type: ApplicationFiled: March 27, 2003Publication date: September 30, 2004Inventor: Albert Philip Van Duren

Patent number: 6541740Abstract: A substantially constant load impedance electrical heater has been provided. The heater is comprised of two sections, a first heater and a second heater. The first heater is continuously “on” to provide the bulk of the heat. A second heater is selectively engaged to provide slightly more heat to the medium, heating the medium to the desired temperature. The output temperature of the heated medium is maintained by controlling the duty cycle of the second heater. More drastic changes in temperature are accomplished by changing the power continuously dissipated by the first heater. The greatest heating control is obtained by defining the first and second heaters as subsets from a bank of selectable heater elements. A method of minimizing fluctuations in the loading of a high-wattage electrical device is also provided.Type: GrantFiled: October 3, 2001Date of Patent: April 1, 2003Assignee: Augustine Medical, Inc.Inventors: Allen Hamid Ziaimehr, Albert Philip Van Duren, Peter Donald Fraley

Patent number: 6447538Abstract: A condition is detected between an inlet port of an inflatable thermal device, such as an inflatable thermal blanket, and an end of an air hose through which a flow of pressurized, thermally treated air is provided to the device by way of the inlet port. The condition may be disconnection of the end of the air hose from the inlet port or the identification of a particular style of inflatable thermal device. A response to the condition may include provision of a perceptible indication that the condition has occurred. Other responses may include cessation of the flow of air or changing an air flow characteristic.Type: GrantFiled: April 10, 2000Date of Patent: September 10, 2002Assignee: Augustine Medical, Inc.Inventors: Albert Philip Van Duren, Allen Hamid Ziaimehr, John Paul Rock, Scott Douglas Augustine, Gary Rabindranath Maharaj
