Abstract

An energy device that is combined with suction can lead to clogging within the device. The suction tube can easily become filled with a mix of saline, blood and tissue fragments to form a clog in the suction line. This clog could prevent a device from functioning properly. A device of this nature needs to prevent, avoid, and/or easily clear clogging for optimal use.

Rifled Inner Lumen on an Energy Device

Summary

Problem statement:

An energy device that is combined with suction can lead to clogging within the device. The suction tube can easily become filled with a mix of saline, blood and tissue fragments to form a clog in the suction line. This clog could prevent a device from functioning properly. A device of this nature needs to prevent, avoid, and/or easily clear clogging for optimal use.

One idea to improve flow of material through the tube is described below.

Description

One way to inhibit the aspirated material in the internal lumen from sticking to the inside of the tube is to rifle (helical grooves) the inside of the tube. This tube could be the energy delivery component or any connected component that includes an internal lumen. This would create a spinning of the aspirated material about the tube axis as it progresses through the device. This could also be combined with a surfactant coating (such as SDBS) on the inside of the tube and in combination with the rifled grooves would assist in pulling the aspirated material through the tube using capillary action along with the suction.
