摘要： A vasoocclusive coil is reinforced with a stretch resistant member to improve safety during retraction of the coil. The stretch resistant member is fixedly attached at one end to the vasoocclusive coil, and the other end of the stretch resistant member is detachably mounted to an elongated pusher member to allow for placement and release of the vasoocclusive coil within the patient's vasculature.

摘要： A roller cone drill bit is disclosed which includes a bit body adapted to be coupled to a drill string. A bearing journal depends from the bit body. A single roller cone is rotatably attached to the bearing journal. The roller cone has a plurality of inserts disposed at selected positions about the cone. The journal defines a rotation angle with respect to an axis of rotation of the bit such that the roller cone includes a wall contact zone and a bottom contact zone. At least one of the inserts disposed in the wall contact zone has an extension portion terminating in a substantially planar upper surface.

摘要： A data processing apparatus and method are provided for managing access to content within the data processing apparatus. The data processing apparatus has a secure domain and a non-secure domain and comprises at least one device which is operable when seeking to access content stored in memory to issue a memory access request pertaining to either the secure domain or the non-secure domain. Further, writeable memory is provided which can store content required by the at least one device, with the writeable memory having at least one read only region whose content is stored therein under control of a secure task, the secure task being a task executed by one of the devices in the secure domain. Protection logic is then used in association with the writeable memory, which on receipt of a memory access request seeking to access content in the at least one read only region, prevents access to that read only region if that memory access request pertains to the non-secure domain and is seeking to write content to the read only region. This enables the speed, power and flexibility benefits of placing content in writeable memory to be achieved without prejudicing the security of that content, by ensuring that that content cannot be modified from the non-secure domain.

摘要： Methods and systems for lung volume reduction of a patient are described. The methods include implanting a flow control device in a bronchial passageway of the lung. The flow control device regulates fluid flow through the bronchial passageway and includes a valve protector that at least partially surrounds a valve member. The valve protector has sufficient rigidity to maintain the shape of the valve member against compression.

摘要： An intravascular flow modifier and vascular reinforcement for treatment of aneurysms is formed of one or more loops of wire of resilient material formed into a series of transverse loops and longitudinal connecting sections to configure an essentially cylindrical reinforcement device that still allows, if desired, access to the neck of an aneurysm for insertion of embolic coils and the like. The proximal and distal regions of the sinusoidal loops may be more tightly coiled than the intermediate regions of the loops, or may have a larger diameter than the intermediate regions. The intravascular flow modifier and vascular reinforcement device can be provided with an outer covering that can be formed as a fiber, and can be woven, or can be formed as a ribbon wound about the intravascular flow modifier and vascular reinforcement device. The wire of resilient material can also be coated with a hydrophilic material. One or more round or oval intermediate loops extending radially outward may also be provided. An apparatus for removing clots may also be formed from one or more loops of wire of resilient material in a hollow conical shape non-detachably joined to a deployment device, to trap and hold clots within a vessel.

摘要： The shape memory segmented detachable coil assembly includes a plurality of hollow, tubular coil segments, and a plurality of connector members, with adjacent coil segments connected together by the connector members. The connector members are currently preferably hollow, tubular connector members that are advantageously detachable from selected portions of the coil segments by application of energy to one or more selected connector members. A heat activation member is used for heating one or more selected connector members to disconnect selected portions of the coil assembly. The heat activation member typically can be advanced axially through or over the coil assembly, and currently preferably comprises a fiber optic, although the heat activation member can also comprise a heat pipe, or a device for generating heat by RF energy or electrical resistance.

摘要： The three dimensional, low friction vasoocclusive coil has a distal portion that is three dimensionally shaped, and a proximal portion that is linear or helically shaped. The distal three dimensional portion will form a basket for filling the anatomical cavity at the site in the vasculature to be treated, while the proximal portion will fill and reinforce the basket. The vasoocclusive device is formed from at least one strand of a flexible material formed to have an a first inoperable, substantially linear configuration for insertion into and through a catheter or cannula to a desired portion of the vasculature to be treated, and a second operable, three dimensional configuration for occluding the desired portion of the vasculature to be treated. The vasoocclusive device has a distal portion having a second operable, three dimensional shape for filing the anatomical cavity at the site in the vasculature to be treated, and a proximal portion having a second operable, substantially linear shape for filling and reinforcing the distal, three dimensional shaped portion when it is implanted at the site in the vasculature to be treated. Mandrels are provided for use in the method of making the vasoocclusive device.
