manufacturer has produced tapered, more flexible guidewires that straighten arterial contours less and push the burr into the edge of a curve less forcefully. The distal 9 cm of the drive shaft tubing was removed, also making the shaft more flexible. With evolution of the shaft-guidewire system biased cutting is reduced. However, in severely angulated segments such as the takeoff of a left circ...

Robert Hooke is commonly thought of as the inventor of ‘Hooke’s joint’ or the ‘universal joint’. However, it is shown that this flexible coupling (based on a four-armed cross pivoted between semicircular yokes attached to two shafts) was in fact known long before Hooke’s time but was always assumed to give an output exactly matching that of the input shaft. Hooke carefully measured the relative...

abstract   background: fractures of the tibia are important for their commonness and controversy in their management. both conservative and surgical techniques have been introduced in an effort to speed time to :::::union::::: while minimizing the occurrence of complications. standard treatment for low-energy tibial shaft fractures includes closed reduction and cast immobilization. the purpose ...

Introduction: In children fractures of the femoral shaft are commonly treated by various types of traction for about 3 weeks, followed by plaster cast immobilization. However little is known about the functional outcome and its complication in Indian scenario. Therefore our aim of study was to analyse the functional outcome in femoral shaft fractures of children operated by flexible intramedull...

BACKGROUND Catheter visualization and tracking remains a challenge in interventional MR.Active guidewires can be made conspicuous in "profile" along their whole shaft exploiting metallic core wire and hypotube components that are intrinsic to their mechanical performance. Polymer-based catheters, on the other hand, offer no conductive medium to carry radio frequency waves. We developed a new "a...
