 Design of the optimum shaft for a device requires balancing a number of performance characteristics - pushability, trackability, torqueability, kink performance, and transition. Achieving the best performance in one characteristic can often directly affect other characteristics. For example, decreasing the wall thickness of a hypotube to improve its trackability may reduce the overall kink performance of the hypotube. The challenge for the product designer is to find the best possible combination of characteristics for their particular application. There are five key areas to consider when designing a hypotube shaft.

 

 Push – the ability of a device to transmit a longitudinal force from the proximal end of the shaft to the distal end. When push is optimized in combination with other hypotube design features it will be easier for the physician to manoeuvre the device to the exact treatment site.

 

 Torque – the ability of the device shaft to transmit a rotational displacement along the length of the device. Rotational movements by the physician translate efficiently to the device tip within the anatomy when torque performance is high.

 

 Kink performance – also known as kink resistance, is the ability of a device shaft to maintain its cross-sectional profile during compressive deformation. When kink performance (resistance) is high, the physician can rely on the device shaft to negotiate difficult routes without fracturing or breaking.

 

 Trackability – describes the ability of a device to travel through complex anatomies and is influenced by a number of factors including the shaft flexibility, strength, and friction within the anatomical environment. Trackability describes the “feel” of the device to the physician when manipulating and positioning the treatment device.

 

 Transition – refers to the change in stiffness along the device shaft. Physicians prefer a device shaft that is flexible at the distal end and stiff at the proximal end as it maximizes the push and torque performance of the device. A well-designed transition along the device shaft will also decrease the likelihood of kinking.
