First Claim
Patent Images
1. A transurethral ablation device, comprising:
- a transurethral catheter;
a lockout to store device usage information;
an ablation needle extendable from a distal end of the catheter to penetrate prostate tissue of a patient and to deliver ablation energy to the prostate tissue;
wherein a controller controls delivery of the ablation energy based on the stored device usage information.

Abstract
A one-piece, single-use disposable device for transurethral needle ablation (TUNA) of prostate tissue to alleviate BPH is disclosed. The device may include a flexible catheter tip including a rigid core and a flexible tip. The device may also include a single use lockout to help ensure that the device is used to perform only one ablation procedure on a single patient. The device may further include a simplified needle deployment mechanism and/or an automatic needle retraction mechanism.
