Ablation device with drug delivery component and biopsy tissue-sampling component

Abstract

An ablation device includes a handle assembly, an ablation electrode extending from the handle assembly, and one or more delivery needles extending from the handle assembly. The ablation electrode includes an ablation needle. The ablation needle includes a distal end portion including a drug delivery port defined therethrough. The ablation device also includes and a biopsy tool extending from the handle assembly.

AI Technical Summary

Benefits of technology

[0015]There is a need for ablation devices capable of collecting tissue samples, e.g., to eliminate the need for a separate, biopsy tissue-sampling device. There is a need for ablation devices capable of dispensing a controlled delivery formulation of a desired active agent. There is a need for devices capable of dispensing a contrast agent to enhance the visualization of the region of interest during a medical procedure. The combination of ablation (e.g., RF ablation and / or microwave ablation) and drug delivery may help to reduce or eliminate tumor reoccurrence. There is a need for an ablation device that is configured to dispense an active agent in a controlled delivery formulation and / or non-active agent (e.g., contrast agent) before, during and / or after ablation, e.g., without the need for further manipulation of the device. A need exists for ablation needles with a drug delivery component. A need exists for ablation needles with absorbent surfaces and / or materials, e.g., to provide tissue retrieving capabilities.

Problems solved by technology

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