摘要:
A medical device package includes an elongate tubular holder having a first and a second detachable tip, and a medical device positioned within a cavity and contained within the holder via the first and second detachable tips. The medical device has a self-shaping bias and is loaded in opposition to the bias via contact with an inner surface of the holder defining the cavity. The first and second detachable tips may include snap-off tips, such that upon detachment the cavity is opened for removing the medical device. Related methodology is disclosed.

An aneurysm closure clip along with a system and method for use by a physician in delivering the closure clip into the vasculature of a patient is disclosed. The closure clip delivery system comprises a delivery tube in the form of a catheter, a guide wire, and a detachable closure clip. The closure clip includes a proximal side and a distal side. The distal side comprises at least two winged elements that interact with the wall of the body vessel to hold the clip in place after delivery. The proximal side includes a seal element and a guide bar. The guide bar is in communication with the guide wire during delivery. The seal element forms a barrier between the aneurysm and the rest of the body vessel, thereby, reducing any pressure exerted on the aneurysm. The seal element and optionally the winged elements include a material layer comprised of bioremodelable material, such as an extracellular matrix material (ECM).

Systems and methods for simultaneous optical testing of a plurality of devices under test. These systems and methods may include the use of an optical probe assembly that includes a power supply structure that is configured to provide an electric current to a plurality of devices under test (DUTs) and an optical collection structure that is configured to simultaneously collect electromagnetic radiation that may be produced by the plurality of DUTs and to provide the collected electromagnetic radiation to one or more optical detection devices. The systems and methods also may include the use of the optical probe assembly in an optical probe system to evaluate one or more performance parameters of each of the plurality of DUTs.
摘要:
A method of communicating between a central location and multiple well locations is disclosed that includes the steps of stimulating a first well from the central location using a first stimulation fluid through a first fluid line; and simultaneously stimulating a second well from the central location using a second stimulation fluid through a second fluid line. An apparatus for centralized well operations is disclosed that includes a well treatment operations factory which manufactures and pumps a well stimulation fluid; a first connection between a first well location and the well operations factory; a second connection between a second well location and the well operations factory; and means for simultaneously flowing a first stimulation fluid to the first well location and a second stimulation fluid to a second well location. Manifolds for centralized well stimulation are disclosed.

摘要:
A solution to an interference effect problem associated with laser processing of target structures entails adjusting laser pulse energy or other laser beam parameter, such as laser pulse temporal shape, based on light reflection information of the target structure and passivation layers stacked across a wafer surface or among multiple wafers in a group of wafers. Laser beam reflection measurements on a target link measurement structure and in a neighboring passivation layer area unoccupied by a link enable calculation of the laser pulse energy adjustment for a more consistent processing result without causing damage to the wafer. For thin film trimming on a wafer, similar reflection measurement information of the laser beam incident on the thin film structure and the passivation layer structure with no thin film present can also deliver the needed information for laser parameter selection to ensure better processing quality.
