Patent number: 8790387Abstract: Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some embodiments include an elastic outer cover positioned outside the outer layer. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.Type: GrantFiled: December 6, 2011Date of Patent: July 29, 2014Assignee: Edwards Lifesciences CorporationInventors: Duy Nguyen, Kim Nguyen, Thanh V.

Patent number: 8790427Abstract: Trace levels of mercury in a natural gas are removed in a gas processing plant in an amine unit and/or a dehydrator. The mercury removal occurs concurrently with the removal of acid gases in an amine unit, e.g., an absorber or scrubber, with an amine solution containing a complexing agent. The mercury removal can also be carried out concurrently with the removal of water in a glycol dehydrator with the addition of a complexing agent to the glycol solution. Volatile mercury in the natural gas is removed by the complexing agent, forming non-volatile mercury species in the rich amine/glycol solution.Type: GrantFiled: September 6, 2013Date of Patent: July 29, 2014Assignee: Chevron U.S.A. Inc.Inventors: Dennis John O'Rear, Russell Evan Cooper, Feng-Ran Sheu, Jordan Taylor Belue
