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.

Diverted Saline to Clear Central Lumen in 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 suction tube is described below.

Description

One way to clear the aspirated material in the internal lumen is to divert the flow of saline from its typical irrigation line terminating at the end of the device into a separate irrigation line that lies inside the suction lumen. The irrigation line inside the suction lumen would have several openings, introducing saline flow along the length of the lumen, which can dislodge clogged materials in 2 ways: 1) lubricating the sides of the clogs to help it pass through the lumen, or 2) adding force to dislodge clogs with increased fluid pressure and a higher flow rate. When the user determines that the device is clogged, that user can activate a switch/valve on the device that diverts the saline from the typical source (located above suction lumen) to the irrigation tubing inside the suction lumen. As a result, the saline will flow down the central lumen with high pressure to clear the clog.
