A catheter is disclosed providing a balloon catheter having a distal tip that is flexible while additionally incorporating high column strength. The present invention additionally provides a distal tip region that accommodates for various sized guidewires. In preferred embodiments, the distal tip region is initially configured for accommodating the passage of 0.12-inch guidewires only. Through specific manufacturing processes, however, the distal tip is modified so that it also may be expanded to accommodate the passage of 0.14-inch guidewires. In additional preferred embodiments, an elastomeric sleeve is disposed over the modified distal tip to allow the tip to return to the initial 0.12-inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.

A method and system for indexing and searching a database of iris images having a system to expedite a process of matching a subject to millions (more or less) of templates within a database is disclosed. The system may progressively match an iris image template to an iris template in a database by progressing from a top layer of the database to a lower layer of the database. Such matching or retrieval may use a subject code as a query or probe and then find a similarity measure for the features of codes or templates in the database. A multi-stage hierarchal clustering process may be used to compress codes and/or templates.
摘要:
A medical device having a segmented construction. In at least some embodiments, a medical device including a plurality of conductive elongated members that are of such a length and are connected together in such a manner to impart a degree of MRI compatibility to the device. In some embodiments, the elongated members can include a series of solid elongate members and tubular elongate members, which construction provides one way to control at least some properties of the device, for example, stiffness, torque transmission, flexibility, shape retention, and the like. In yet some additional embodiments, at least one of the elongated members has a recess into which a protrusion of another elongated member may fit.

Electronic devices that include batteries can be adapted to provide one or more indications of a low battery condition. An electronic device such as a controller can include a battery and can be adapted to determine a first low battery condition. A first indication can be provided in response to the first low battery condition. In some cases, a second battery condition can be determined and a second indication can be provided in response to the second battery condition. The indications provided to the user can be made progressively more noticeable over time, until the battery is replaced.

In one embodiment, a spinal stabilization apparatus includes a vertebral anchor having a head portion and a bone attachment portion. An elongate, flexible guide is removably coupled to the head portion of the vertebral anchor and has a channel extending longitudinally thereof and communicating with a slot in the head portion of the anchor. An elongate cord may be received within the channel to facilitate inserting and securing a spacer between pairs of anchors installed into adjacent vertebrae of a person's spine.
摘要:
Methods of providing dehumidification control in unoccupied spaces are disclosed. An illustrative method can include the steps of providing a controller having an away mode of operation adapted to provide dehumidification within the interior space of a building or room, providing one or more system components adapted to control the humidity and/or temperature within the interior space, initiating the away mode of operation within the controller, and operating the one or more system components for at least one cycle to reduce the humidity within the interior space.
摘要:
In a method of treating the spine of a patient, an access device is inserted into the patient with the access device in a first configuration having a first cross-sectional area at a distal portion thereof. The access device is actuated to a second configuration having an enlarged cross-sectional area at the distal portion thereof such that the distal portion extends across at least a portion of each of two adjacent vertebrae. A stabilization of the vertebrae is then achieved using either translaminar facet screw fixation or transfacet pedicle screw fixation.
摘要:
Bone fixation systems for stabilizing bones such as vertebral bodies are disclosed. The fixation systems include fixation connectors that preferably are equipped with bone anchors (e.g., screws, hooks, pins or like structures) for securing the fixation connectors to bones desired to be stabilized. The fixation systems also include linking elements (e.g., rods, plates or other members) for linking the fixation connectors together to form a stabilizing construct capable of maintaining a desired spacial relationship between bones desired to be stabilized.
摘要:
A portable fuel cell charger has a water source and an electrolyzer coupled to the water source and adapted to be coupled to a power source. A fuel cell cartridge coupler is coupled to the electrolyzer and is adapted to be coupled to a fuel cell cartridge for providing pressurized hydrogen from the electrolyzer to the fuel cell cartridge.
摘要:
A system for tracking objects across an area having a network of cameras with overlapping and non-overlapping fields of view. The system may use a combination of color, shape, texture and/or multi-resolution histograms for object representation or target modeling for the tacking of an object from one camera to another. The system may include user and output interfacing.
