Patent number: 8574191Abstract: Medical devices including a substrate that are expandable from a compressed state to an expanded state; a coating on the substrate, the coating having a drug agent incorporated therein; and a sheath over the coating. The sheath is expandable from a compressed state to an expanded state and has at least one perforation therein. The medical devices are configured such that when the substrate is in a compressed state, the sheath is also in a compressed state and the perforation is substantially closed. When the substrate is in an expanded state, the sheath is also in an expanded state and the perforation is substantially open. The invention also includes a method of using the medical devices for the controlled, localized delivery of a drug agent to a target location within a mammalian body.Type: GrantFiled: August 14, 2012Date of Patent: November 5, 2013Assignee: Boston Scientific Scimed, Inc.Inventor: Charles D. Lennox

Patent number: 8529613Abstract: A thermal cap that can fit a variety of head sizes is disclosed. The cap can include a shell having a fluid inlet and outlet, a sealing mechanism and removable sizing layers disposed within the shell. Depending upon the size of a patient's head, sizing layers can either be added to or removed from the outer shell to maintain a fluid circulation space between the head and the rigid shell and allow substantially even distribution of a thermal fluid about the scalp of the patient during operation. The shell is preferably rigid and an elastomeric member can seal the periphery of the cap to the patient's head to prevent leakage. Other types and aspects of thermal cap systems are also disclosed.Type: GrantFiled: October 11, 2007Date of Patent: September 10, 2013Assignee: MedCool, Inc.Inventors: Jeffrey Radziunas, Charles D.

Patent number: 8454671Abstract: A cooling system includes a console and a tissue cooling device such as a head-cooling device. An operator applies the head-cooling device to the head of a patient at risk for ischemic injury. The console provides a cooling fluid to a fluid circulation space located between the cooling device and the patient's head under a positive gage pressure. Direct contact between the cooling fluid and the patient's head provides a relatively rapid induction of systemic hypothermia in the patient, thereby minimizing or preventing ischemic injury in the patient. The console also removes air from a channel disposed about an inner rim of the cooling device, using a negative gage pressure. Such removal of the air from the channel seals the rim of the cooling device to the head of the patient, including portions of the channel in contact with hair of the patient's head, and minimizes leaking of the cooling fluid beyond the rim of the cooling device.Type: GrantFiled: November 23, 2009Date of Patent: June 4, 2013Assignee: MedCool, Inc.Inventors: Charles D. Lennox, Steven M. Johnson, Susan Beinor, Maria Benson, Don Paul Nogueira, John W. Carroll, Helen Maslocka

Patent number: 7507250Abstract: Disclosed is a system and method for inducing therapeutic levels of hypothermia in a patient in the emergent care setting. The system consists of a small battery operated console and one or more garments. The garments are connected to the console by one or more umbilicals. The console provides cold fluid to the garments under pressure and the garment cools the surface of the body. Fluid returns from the garment back to the console in a closed loop fashion. The console contains an electrical battery and a thermal battery that provides operation of the system for more than one hour. The cooling capacity of the system is sufficient to induce therapeutic levels of hypothermia in approximately 30 to 90 minutes in most patients. Use of the system does not preclude any therapeutic or diagnostic interventions that are commonly performed in the emergent care setting.Type: GrantFiled: October 11, 2005Date of Patent: March 24, 2009Assignee: MedCool, Inc.Inventor: Charles D.

Patent number: 7241307Abstract: A fluid transfer assembly includes a fluid carrier and a heat exchange assembly coupled to the fluid carrier. The heat exchange assembly includes a heat exchange conduit, a heat exchanger in thermal communication with the heat exchange conduit, and a pump. The pump defines a stroke volume that is greater than a fluid carrier volume defined by the fluid carrier. The configuration of the stroke volume of the pump and the fluid carrier volume of the fluid carrier limits the length of the fluid carrier. In such a configuration, the heat exchange assembly orients in proximity to the body during operation to create a relatively short ex vivo flow path between a body and the heat exchange assembly. During operation, as the fluid flows along the ex vivo flow path, the relatively short ex vivo flow path minimizes thermal change in the fluid caused by a heat exchange between the walls of the fluid carrier and the atmosphere.Type: GrantFiled: January 15, 2004Date of Patent: July 10, 2007Assignee: MedCool, Inc.Inventor: Charles D.

Patent number: 7156867Abstract: Disclosed is an apparatus and method for uniform selective cerebral hypothermia. The apparatus includes a brain-cooling probe, a head-cooling cap, a body-heating device and a control console. The brain-cooling probe cools the cerebrospinal fluid within one or more brain ventricles. The brain-cooling probe withdraws a small amount of cerebrospinal fluid from a ventricle into a cooling chamber located ex-vivo in close proximity to the head. After the cerebrospinal fluid is cooled it is then reintroduced back into the ventricle. This process is repeated in a cyclical or continuous manner. The head-cooling cap cools the cranium and therefore cools surface of the brain. The combination of ventricle cooling and cranium cooling provides for whole brain cooling while minimizing temperature gradients within the brain.Type: GrantFiled: December 27, 2002Date of Patent: January 2, 2007Assignee: MedCool, Inc.Inventor: Charles D.

Patent number: 7144418Abstract: Disclosed is a method and system for inducing selective cerebral hypothermia. The system includes a brain cooling device, a body warming device, and a control console. Brain cooling is accomplished with a ventricle catheter where cold fluid is circulated within one or both lateral ventricles. Body heating is accomplished with a central venous catheter. By combining effective brain cooling with controlled body warming, hypothermia therapy can be applied selectively to the brain thereby avoiding the serious complications associated with whole body hypothermia therapy.Type: GrantFiled: October 31, 2002Date of Patent: December 5, 2006Assignee: MedCool, Inc.Inventor: Charles D.
