Abstract
Tubular assemblies are disclosed herein. According to some embodiments, the present technology includes an elongate member having a longitudinally extending tendon, wherein the tendon includes a tapered region along which the width of the tendon continuously decreases. The elongate member can include first and second portions on either side of the tendon and separated from the tendon by respective first and second slits. Each of the first and second slits have a slit length, the slit length being the longest distance measured across the respective slit along a line substantially parallel to the longitudinal axis of the elongate member. The tapered region can have a tapered region length greater than the slit length.
Claims20
An instrument, comprising:
- an elongate member having a first end portion, a second end portion, and a longitudinal axis extending therebetween, the elongate member comprising a tubular sidewall having:
- a tendon extending longitudinally along the sidewall and having a width measured between first and second sides of the tendon, the tendon manufactured from the sidewall by forming a first slit in the sidewall at the first side of the tendon and a second slit in the sidewall at the second side of the tendon, wherein the tendon includes a tapered region along which the width of the tendon continuously decreases,
- a first portion circumferentially adjacent the first side and separated from the tendon by the first slit,
- a second portion circumferentially adjacent the second side and separated from the tendon by the second slit,
- wherein each of the first and second slits have a slit length, the slit length being the longest distance measured across the respective slit along a line substantially parallel to the longitudinal axis of the elongate member, and
- wherein the tapered region has a tapered region length greater than the slit length of the elongate member in an as-manufactured state.

An instrument, comprising:
- an elongate member having a first end portion, a second end portion, and a longitudinal axis extending therebetween, the elongate member comprising a tubular sidewall having:
- a tendon extending longitudinally along the sidewall and having a width measured between first and second sides of the tendon, the tendon manufactured from the sidewall by forming a first slit in the sidewall at the first side of the tendon and a second slit in the sidewall at the second side of the tendon, wherein the tendon includes a tapered region along which the width of the tendon continuously decreases,
- a first portion circumferentially adjacent the first side and separated from the tendon by the first slit,
- a second portion circumferentially adjacent the second side and separated from the tendon by the second slit,
- wherein each of the first and second slits have a slit length, the slit length defined by the longest distance measured across the respective slit along a line substantially parallel to the longitudinal axis of the elongate member, and
- wherein the tapered region has a tapering angle measured between the line and an edge of the first portion the defines the first slit, the tapering angle being about 0.01 degrees to about 2 degrees.

An instrument, comprising:
- an elongate member having a first end portion, a second end portion, and a longitudinal axis extending therebetween, the elongate member comprising a tubular sidewall having:
- a tendon extending longitudinally along the sidewall and having a width measured between first and second sides of the tendon, the tendon manufactured from the tube by forming a first slit in the sidewall at the first side of the tendon and a second slit in the sidewall at the second side of the tendon, wherein the tendon includes a tapered region along which the width of the tendon continuously decreases,
- a first portion circumferentially adjacent the first side and separated from the tendon by the first slit,
- a second portion circumferentially adjacent the second side and separated from the tendon by the second slit,
- wherein each of the first and second slits have a slit length, the slit length defined by the longest distance measured across the respective slit along a line substantially parallel to the longitudinal axis of the elongate member, and
- wherein a functional distance of the tendon is less than the slit length of the elongate member in a neutral position, the functional distance comprising an axial displacement required of the tendon to perform a predetermined function as intended during operation of a tube assembly incorporating the elongate member.
