Abstract: Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.

Abstract: A method and an apparatus or machining a workpiece include the use of a cryogenically cooled oxide containing ceramic cutting tool. The method involves cryogenic cooling of the cutting tool during a cutting operation, which cooling results in enhanced wear resistance and fracture resistance of the cutting tool. A preferred embodiment involves jetting a cryogenic fluid directly at the cutting tool.

Abstract: A method is provided for associating content objects with a database wherein the content objects are accessible over a network communication medium by a user. The method includes: receiving a suggestion for a new content object for addition to the database; approving the suggested content object; generating a list of information users desiring the approved content object; compelling an information provider to provide the desired content object based at least in part on demand identified by the generated list; and making the generated content object available to the database.

Abstract: A surgical method and apparatus for positioning a diagnostic or therapeutic element within the body. The apparatus may be catheter-based or a probe including a relatively short shaft.

Abstract: An apparatus is provided for distributing content objects to a personalized access point of a user over a network-based environment. The apparatus includes a server, a selection client, and a retrieval client. The server includes a database operative to store indicia associated with at least one content object and further operative to store user identifiers as well as information about which content objects have been selected by a particular user. The selection client communicates with the server via a communication link. The selection client is configured to allow a user to select content objects to add to a personalized access point by submitting an indicia and a user identifier to the server. The retrieval client communicates with the server over a communication link allowing a user to retrieve information from a personalized access point.

Abstract: A method for enabling an entity of a group of entities in a region to comply with a regulation regarding a pollutant to be discharged in the region from a point source operated by an entity includes: establishing an administrator in communication with the entities; establishing an amount of discharge of the pollutant from a point source operated by a first entity within the region during a period; comparing the amount of discharge of the pollutant from the point source and an amount of allowance allocated to the first entity during the period to assess compliance of the first entity with the regulation; establishing a value for the amount of allowance to be allocated by the first entity to discharge the pollutant from the point source; communicating that value to the administrator or a second entity; and defining a solution enabling the first entity to comply with the regulation.

Abstract: An inbred sweet corn line, designated X532Y, is disclosed. The invention relates to the seeds of inbred corn line X532Y, to the plants of inbred corn line X532Y and to methods for producing a corn plant produced by crossing the inbred line X532Y with itself or another corn line. The invention further relates to hybrid corn seeds and plants produced by crossing the inbred line X532Y with another corn line.

Abstract: This is a composite guidewire for use in a catheter and is used for accessing a targeted site in a lumen system of a patient's body. The guidewire core or guidewire section may be of a stainless steel or a high elasticity metal alloy, preferably a Ni--Ti alloy, also preferably having specified physical parameters. The composite guidewire assembly is especially useful for accessing peripheral or soft tissue targets. Variations include multi-section guidewire assemblies having (at least) super-elastic distal portions and super-elastic braided reinforcements along the mid or distal sections. A variation of the inventive guidewire includes the coating of the wire with a tie layer and then with a one or more lubricious polymers to enhance its suitability for use within catheters and with the interior of vascular lumen.

Abstract: This invention is an apparatus for endovascular occlusion through the formation of thrombi in arteries, veins, aneurysms, vascular malformations, and arteriovenous fistulas. In particular, it deals with an improved sacrificial link between an endovascular device which is introduced to and is intended to remain at the desired thrombus formation site and the device used to introduce the device. The invention further includes a method for introduction of the device and its electrolytic separation.

Abstract: This invention is a surgical device. In particular, it is a catheter suitable for treating a tissue target within the body, which target is accessible through the vascular system. Central to the invention is the use of a multi-component distal section having an interior stiffener and an exterior tubing member.

Abstract: An electromagnetically actuated friction welder produces orbital motion at interfaces between parts (usually of thermoplastic material) to bond the parts by fusion generated by friction. This welder can also be operated alternatively to produce reciprocating vibratory forces thereby providing flexibility as to the selection of an orbital or reciprocating mode, depending upon the joint to be welded. The velocity of motion is controllable preferably around the resonant frequency of the driven structure by adjusting the frequency of the AC power which operates the electromagnetic drive motor of the welder. A plate which carries one of the parts to be welded and which is driven is flexurally mounted for movement in an orbital plane or planes containing the interfaces without substantial tilting by an array of stiff members, such as rods, located around the drive motor, attached to the plate at one end and to a tubular structure at the opposite ends thereof.
