Atraumatic Tip Geometry For Indwelling Devices |
| 摘要 |
An indwelling device for insertion in a biological tubular structure comprising an elongated device having a body and opposing ends. The body has a bending stiffness transverse to a longitudinal axis that is greater than a stiffness of the biological tubular structure. An atraumatic tip member, having a proximal end and a distal end, extends from the end of the elongated device. The proximal end has a first bending stiffness transverse to a longitudinal axis and the distal end has a second bending stiffness transverse to the longitudinal axis, wherein the second bending stiffness being less than the first bending stiffness. |

1. An indwelling device for insertion in a biological tubular structure, the indwelling device comprising:
an elongated device having a body and opposing ends, the body having a bending stiffness transverse to a longitudinal axis that is greater than a stiffness of the biological tubular structure; and an atraumatic tip member having a proximal end and a distal end, the proximal end extending from the end of the elongated device, the proximal end having a first bending stiffness transverse to a longitudinal axis and the distal end having a second bending stiffness transverse to the longitudinal axis, the second bending stiffness being less than the first bending stiffness. |
