  • Patent number: 10905850
    Abstract: A catheter for insertion into a body of a patient, and methods of making and using. The catheter can include a distal portion that remains stable during fluid infusion into the patient, thus reducing or eliminating whipping of the catheter distal tip. The catheter includes at least one lumen and can be configured such that the arithmetic product of an elastic modulus and an area moment of inertia for the distal portion of the catheter is greater than the arithmetic product of an elastic modulus and an area moment of inertia for a proximal portion. The catheter can be attached to an implantable access port that may include features for use as a power injectable access port.

  • Patent number: 10508528
    Abstract: A method for in situ solution mining of a mineral from an underground evaporite stratum using a set of wells in fluid communication with at least one mineral cavity with some wells operated in solvent injection mode and other wells operated in brine production mode and optionally with some inactive wells, comprising switching the operation mode of one or more wells. The evaporite mineral preferably comprises trona. The at least one cavity may be formed by directionally drilled uncased boreholes or by lithological displacement of the evaporite stratum at a weak interface with an underlying insoluble stratum by application of a lifting hydraulic pressure to create an interfacial gap. The extracted brine can be processed to make valuable products such as soda ash and/or any derivatives thereof.

  • Patent number: 9884165
    Abstract: A multi-lumen catheter including an elliptical cross-sectional profile configuration that enhances fluid flow rate while minimizing the average diameter of the catheter body is disclosed. In one embodiment the catheter comprises an elongate catheter tube defining a plurality of lumens. At least a portion of the longitudinal length of the catheter tube defines an elliptical cross section, in turn defined by a major axis and a minor axis. A ratio of the major axis to the minor axis of the elliptical catheter tube cross section is between about 1.3 and about 1.4 in one embodiment. The catheter body can define two, three, or more lumens, in one embodiment.
