A terminal guide for a helically wound drive shaft for use in an rotational atherectomy device. The terminal guide is atraumatic to prevent perforation of the arterial wall or the embedding of the device into the arterial wall. The terminal guide may be pre-machined, cast, molded or formed in any manner that maintains the required dimensions and tolerances and may be fabricated from any biocompatible material and coated with radiopaque material to more accurately position the rotational atherectomy device without going past the distal end of the pre-positioned guide wire.

A guide wire for assisting in implantation and balancing of an orbital atherectomy device is disclosed. The guide wire is generally configured to be received within a driveshaft and cutting region of the orbital atherectomy device. The guide wire is sufficiently flexible to minimize trauma to the vessel walls is positioned within a patient. The distal end of the guide wire can include on or more weighted elements movable along the distal region of the guide wire to permit the balancing of an a rotating drive shaft and cutting region of an orbital atherectomy device. The guide wire can also include an atraumatic tip located on the end of the guide wire to reduce trauma to the vessels during implantation. Lubricious coatings are also provided to reduce friction between the driveshaft and cutting region of the atherectomy device and guide wire.

A modular earth retaining wall system comprising a plurality of similarly configured wall blocks that have lock channels and lock flanges that provide a locking mechanism for resisting leaning or toppling of the blocks. A positive retaining mechanism is also provided for attaching reinforcement fabrics to the retaining wall in between mating courses of wall blocks. This mechanism secures the reinforcement fabrics in place and permits the fabrics to extend along the entire contact area between adjacent stacked wall blocks to avoid an aggregate leaning effect. The retaining mechanism includes a retaining bar that is placed on top of the reinforcement fabric within the lock channel. The retaining bar holds the fabric against a wall of the lock channel in response to tensile loads applied to the fabric to prevent it from being pulled out of the retaining wall.

A wall block for use in a segmental retaining wall system. The wall block comprises an interior face for forming an interior surface of a segmental retaining wall, an exterior face for forming an exterior surface of the segmental retaining wall, first and second sides that extend from the exterior face to the interior face, and a top surface and a bottom surface. Further provided in the wall block is a channel defined by a front wall, a rear wall, and an arcuate bottom surface. The channel extends across one of the faces and surfaces.

Medical electrical leads for sensing or electrical stimulation of body organs or tissues, particularly implantable cardiac leads for delivering pacing pulses and cardioversion/defibrillation shocks, and/or sensing the cardiac electrogram (EGM) or other physiologic data and their methods of fabrication are disclosed. A lead body sheath is co-extruded in a co-extrusion process using bio-compatible, electrically insulating, materials of differing durometers in differing axial sections thereof, resulting in a unitary lead body sheath having differing stiffness sections including axial segments or webs or lumen encircling rings or other structures in its cross-section. The lead body sheath is co-extruded to have an outer surface adapted to be exposed to the environment or to be enclosed within an outer sheath and to have a plurality of lead conductor lumens for receiving and enclosing a like plurality of lead conductors of the same or differing types. The lead body sheath can be co-extruded of a plurality of sheath segments containing a lead conductor lumen and formed of a first durometer material or of differing durometer materials. A web of a further durometer material can be co-extruded extending between the adjoining boundaries of the axial sheath segments and bonding the adjacent segments together.

607122

A medical electrical lead having a multiple conductors located within an elongated lead body which is provided with multiple conductor lumens each containing a conductor and with at least one compression lumen which does not contain a conductor. The conductor lumens are spaced from one another by a first, minimum spacing and the compression lumen or lumens are located intermediate the conductor lumens and are spaced from the conductor lumens by a second, minimal spacing of less then said first minimum spacing. The centers of the compression lumens are located along lines which pass through the both the center of a conductor lumen and the center of the lead body. The arrangement of the conductor and compression lumens enhances the lead's ability to survive crushing forces such as applied by the first rib and clavicle.
