Multi-compliant tubing
First Claim
1. An aspiration tubing, comprising:
- a high compliant section;
a low compliant section having a different geometry than the high compliant section, wherein the different geometry gives the low compliant section a lower compliance than the high compliant section;
a transition section coupling the high compliant section to the low compliant section such that fluid can travel through the transition section from the high compliant section and into the low compliant section;
wherein the transition section comprises a length of tubing that is continuous with the high compliant section and the low compliant section;
wherein an end of the transition section adjacent the high compliant section matches the geometry of the high compliant section and wherein an opposing end of the transition section that is adjacent the low compliant section matches the geometry of the low compliant section;
wherein the transition section gradually changes geometry along the length of the transition section between matching the end adjacent the high compliant section and matching the opposing end adjacent the low compliant section;
wherein the high compliant section is configured to couple to a handpiece; and
wherein the low compliant section is configured to couple to a surgical console.

Abstract
In various embodiments, aspiration tubing connecting a handpiece to a surgical console may include a high compliant section, a transition section, and a low compliant section. In some embodiments, the high compliant section may have a lower durometer and/or different geometry than the low compliant section. The transition section may take a number of forms, including a connector or a continuous section of tubing that gradually increases in durometer and/or changes geometry through the length of the tubing. In the various embodiments, the high compliant section may provide flexibility near the handpiece to make the handpiece easier to hold and maneuver while the low compliant section may reduce the effects of occlusion break surge. In some embodiments, the high compliant section may include, for example, ribs, stiffening rings, a stiffening sleeve, or a stiffening sock to increase the stiffness of the high compliant section.
