Cut patterns
The three patterns a catheter shaft is built on, the mechanism behind each, and how they compare with a braid or a coil on torque lag, kink and ovalization.

Reading a spec
What the three numbers on every product page mean, and a fifteen-part table from one 1F family showing how they move the modelled bend radius from 0.51 in to 3.76 in.

Materials
Modulus, recoverable strain, torque per degree of twist, cost and cut behaviour, and why the stock catalog is 304 while nitinol is a quoted part.

Prototyping
Order three rhythms of one size from the catalog, bench them, then send the numbers for a custom cut. Two design turns a week without a supplier conversation.
Read →The point of every article
The incumbents' articles end in a form. Ours end in three catalog parts you can order for $600, bench in a week, and follow with a custom cut that leaves in two to three days. The store is the resource.
