Benefits of technology

The patent text discusses the need for ablation devices that can collect tissue samples, dispense a controlled delivery of active agents, and enhance the visualization of the region of interest during a medical procedure. Combining ablation with drug delivery can help to reduce or eliminate tumor reoccurrence. The text also mentions the need for ablation needles that have a drug delivery component, absorbent surfaces or materials for tissue retrieving capabilities, and the ability to dispense a contrast agent for better visualization.

Problems solved by technology

Despite advancements in the use of electrosurgical devices for treating biological tissue, there are still concerns for tumor reoccurrence.
