Abstract
A prostate therapy system is provided that may include any of a number of features. One feature of the prostate therapy system is that it can access a prostate lobe from the urethra. Another feature of the prostate therapy system is that it can deliver condensable vapor into the prostate to ablate the prostate tissue. Another feature of the prostate therapy system is that it can aspirate tissue from the prostate. Yet another feature of the prostate therapy system is that it can rotate during delivery of vapor and aspiration of tissue. Methods associated with use of the prostate therapy system are also covered.
Claims23
A method of extracting tissue from a patient's prostate comprising:
- introducing a tissue extraction member into a urethra of the patient;
- rotating the tissue extraction member within the urethra;
- injecting condensable vapor from the tissue extraction member;
- and
- aspirating prostate tissue into the tissue extraction member.
A prostate therapy system comprising:
- a condensable vapor source;
- and
- a tissue extraction member adapted to be inserted into a urethra of an adult male human subject and to rotate within the urethra,
- the tissue extraction member having a vapor delivery port communicating with the vapor source and adapted to deliver condensable vapor to the prostate lobe and an aspiration port adapted to aspirate prostate tissue proximally into the ablation probe.
