Patent number: 8162055Abstract: The present disclosure is directed to a system and method for managing cement in a subterranean zone. In some implementations, a method of cementing in a subterranean formation includes positioning a cement slurry including a plurality of activation devices in a wellbore. The activation devices configured to release an activator that increases a setting rate of the cement slurry. A signal is transmitted to at least a portion of the cement slurry to activate the activation devices. The activation device releases the activator in response to at least the signal.Type: GrantFiled: August 25, 2009Date of Patent: April 24, 2012Assignee: Halliburton Energy Services Inc.Inventors: Sam Lewis, Priscilla Reyes, Craig Roddy, Lynn Davis, Mark Roberson, Anthony Badalamenti

Patent number: 8147540Abstract: This disclosure relates to implantable medical devices coated with a taxane therapeutic agent, such as paclitaxel, in one or more solid form(s) having varying dissolution rates. Particularly preferred coatings comprise amorphous and/or solvated solid forms of taxane therapeutic agents that provide durable coatings that release the taxane over a desired period of time, which can be varied in the absence of a polymer by selecting the type and amount of solid forms of the taxane therapeutic agent in the coating. Other preferred embodiments relate to methods of coating medical devices and methods of treatment. The coatings can provide a sustained release of the taxane therapeutic agent within a body vessel without containing a polymer to achieve the desired rate of paclitaxel elution.Type: GrantFiled: January 5, 2011Date of Patent: April 3, 2012Assignee: Cook Medical Technologies LLCInventors: Priscilla Reyes, William F. Moore, Patrick H. Ruane, Darin G. Schaeffer, Melinda S. Morrell

Patent number: 8047282Abstract: The present disclosure is directed to a system and method for sonically activating cement slurries. In some implementations, a method of treating a subterranean formation includes positioning a settable composition including a capsule in a wellbore. The capsule is used to increase a setting rate in response to at least sonic signals. A sonic signal is transmitted to at least a portion of the settable composition to release an activator from the capsule.Type: GrantFiled: August 25, 2009Date of Patent: November 1, 2011Assignee: Halliburton Energy Services Inc.Inventors: Sam Lewis, Priscilla Reyes, Vijay Gupta, Brian R. Stoner, Anthony Badalamenti

Publication number: 20080286325Abstract: The present disclosure provides methods of measuring the release of a taxane therapeutic agent from a medical device as a function time in contact with a suitable elution medium. The method preferably comprises the step of contacting a coated medical device comprising a taxane therapeutic agent with an elution medium comprising a cyclodextrin to provide an elution profile indicative of the composition or configuration of a medical device coating comprising a taxane therapeutic agent. The elution profile can provide information about the medical device coating that is useful in lot release testing.Type: ApplicationFiled: July 6, 2007Publication date: November 20, 2008Applicant: MED Institute, Inc.Inventors: Priscilla Reyes, Patrick H.
