Guide Sheath Dilator And Method Of Using The Same
The present invention relates to a dilator. The dilator includes a shaft, a lumen and a hub. The shaft has at least two stiffness sections with the stiffness sections becoming less rigid as they approach a distal end of the shaft. The varying stiffness sections allow the dilator to track along the guidewire through torturous vasculature so as the dilator is advanced and the stiffness is changed, the stiffer sheath can advance smoothly through a blood vessel. The dilator may also taper at the distal tip to stretch the initial skin puncture hole larger to accommodate the dilator shaft and ease the sheath tip insertion through to the vasculature. Or the shaft may taper from where it extends beyond the sheath distal tip to the distal end so that it can reach further distal in the vasculature. The dilator may also include an atraumatic tip for easier advancement of the dilator. The dilator distal end may also include one or more radiopaque markers and a shaped distal end.

ActiveUS20060189942A1Further advancement of the catheter easierEasy to handleInfusion syringesSurgeryInsertion siteNeedle guard
A skin puncture device for use as an intravenous catheter or blood collecting needle set is provided with a mechanism for protection against needle injury and access to fluid passageway during insertion. The assembly includes a flexible extension tube connected to the proximal end of the needle housing for use in difficult insertion sites. The extension tube provides access for fluid injection so that the passageway and needle can be filled with fluid prior to needle / catheter insertion, allowing diffusion of blood to provide evidence of successful venipuncture and allowing the infusion of small amounts of fluid into the vein to facilitate catheter advancement. The locking mechanism consists of two apertures in the needle housing and two pairs of needle guard locking tabs which selectively engage when the needle guard is pushed forward to its fully extended position upon completion of insertion or blood drawing, encapsulating the length of the needle.

Provided is a microneedle device which protects a microneedle, has an easily portable shape, is free from such problems as breakage of small needles in the step of puncturing the skin with the microneedle, and ensures appropriate skin puncture to administer a drug. By studying the relationship between the device to be pressed to the skin and the height of the elevation of the skin surface during the pressing, it is found that there is a positive correlation between the placement and interval of skin fixing members and the height of the elevation of the skin. It is furthermore found that the elevated skin surface is always parallel to the flat plate of the device. This reveals that since the microneedle installed in the device can be inserted at right angle to the skin surface, the skin can reliably be punctuated avoiding the breakage etc. of the small needles of the microneedle. Thus, a microneedle patch which is easily portable and ensures convenient drug administration to the skin can be produced.

Method of preventing reuse in an analyte measuring system
InactiveUS20050284773A1Prevent reuseIncrease resistanceImmobilised enzymesBioreactor/fermenter combinationsGlucose meter deviceEngineering
The present invention is a method of preventing reuse of test strips for measuring an analyte or indicator such as glucose in a physiological fluid such as blood, interstitial fluid, or urine. The present invention also relates to a method of preventing reuse of test strips incorporating an integrated lance such as a needle, blade, or other sharp or skin puncturing device. Certain types of medical devices such as, for example, glucose test strips were intended to be tested only once and then disposed. This requirement is often needed because the reagent chemistry in many test strips is not suitable for measuring glucose a second time. However, it is possible that some user will accidentally test a previously used test strip. This could potentially become a problem if the glucose meter attempts to make a glucose measurement and outputs a result. Therefore, it is desirable that a single use test strip and meter have a prescribed method for preventing a previously tested test strip from being reused.
