摘要:
A catheter to be passed over a guidewire, including a screw portion with a cylindrical hollow shaft and a helical thread portion extending outwardly from the hollow shaft. The screw portion is secured coaxially to a tubular portion formed from a substantially rigid material. The tubular portion has, along a portion of its length, at least two slits having a pattern geometry that limits torsional displacement. The catheter also includes a hub having a lumen joined substantially coaxially to the tubular portion.
摘要:
A guidewire converter for use in intravascular procedures along with a guidewire. The guidewire converter includes an elongate tubular structure defining a lumen having an inner diameter and a first outer diameter. The inner diameter of the lumen is sized to receive the guidewire for intravascular procedures. The guidewire converter includes a locking mechanism coupled to the elongate tubular structure that has a second outer diameter that is less than or substantially equal to the first outer diameter. Operation of the locking mechanism releasably secures the elongate tubular structure to the guidewire.

摘要:
A stent delivery system for delivering a stent comprising, a stent disposed on the distal end of the catheter, and an inner core, wherein the inner core is resistant to appreciable compression or accordion. The catheter further comprising a first sheath covering a portion of the inner core, wherein at least a portion of the distal end of the inner core is left uncovered by the first sheath, a retractable sheath which covers at least a portion of the stent and a portion of the distal end of the inner core and a retracting means for retracting the distal sheath to release the stent.
摘要:
A tile for lining an internal surface in a heavy wear area. The tile includes at least one locating rod embedded within said tile and an internal mechanism for laterally extending said at least one locating rod out of said tile and into a gap in an adjoining structure which may be another tile. The tiles forming the lining surface are securely held in place as a result of the selective deployment of the locating rods into a gap in the adjoining structure.
摘要:
An improved identification band such as a wristband is provided for mounting onto a specific person or object. The improved identification band includes a primary identification zone adapted to receive human-readable and/or machine readable information as by printing and/or programming of a radio frequency identification (RFID) circuit. The band further includes multiple detachable adhesive labels forming a portion of the band or alternately forming a tail end extension thereof, wherein each label is adapted to receive human-readable and/or machine readable information as by printing and/or programming of a radio frequency identification (RFID) circuit. In use, such as when worn by a patient in a hospital or the like, the detachable labels are individually separable from the identification band on an as-needed basis for adherence to other objects associated with the band wearer, such as a vial containing a patient blood sample or the like.

An identification band for attachment to an individual or object includes an at least partially non-transparent elongated hollow body having first and second opposite ends. The body also includes a substantially flat intermediate portion with top and bottom surfaces and semi-circular edges, and a pair of fastening openings formed respectively at the first and second ends. A connector is configured for interference fit reception into the fastening openings for removably attaching the first and second ends of the body. The connector is removable from the fastening openings and adapted for subsequent assembly and re-use with a replacement body. A machine readable radio frequency identification chip is associated with the body, and an antenna is operatively connected to the chip.
摘要:
A plurality of identification bracelets removably attached to one another, each bracelet having a first end which includes a cover tab and a second end defining a closure tab having an adhesive portion. The cover tab of a second bracelet removably overlies the adhesive portion of a closure tab of an adjacent first identification bracelet. Upon separating the first and second bracelets, the adhesive portion of the first bracelet is exposed and the cover tab remains with the second bracelet as it is removed. The adhesive portion of the closure tab of the first bracelet is adhered to a surface of the first bracelet as it is moved from an open position to a closed position encircling an object to be identified.
