Definitions

  • the present invention relates to devices and related methods for treatment of the prostate using a minimally invasive approach.
  • the prostate early in life is the size and shape of a walnut and prior to the enlargement resulting from BPH, weighs about 20 grams. Prostate enlargement appears to be a normal process. With age, the prostate gradually increases in size to twice or more its normal size. The fibromuscular tissue of the outer prostatic capsule restricts expansion after the gland reaches a certain size. Because of such restriction on expansion, the intracapsular tissue will compress against and constrict the prostatic urethra, thus causing resistance to urine flow.
  • the prostate can be classified into three zones: the peripheral zone, transition zone, and central zone.
  • Peripheral zone (PZ) comprises about 70% of the volume of a male's prostate. This sub-capsular portion of the posterior aspect of the prostate gland surrounds the distal urethra and 70% to 80% of cancers originate in the peripheral zone tissue.
  • the central zone (CZ) surrounds the ejaculatory ducts and contains about 20-25%) of the prostate volume.
  • the central zone is often the site of inflammatory processes.
  • the transition zone (TZ) is the site in which benign prostatic hyperplasia develops, and contains about 5-10% of the volume of glandular elements in a normal prostate, but can constitute up to 80% of such volume in cases of BPH.
  • the transition zone includes two lateral prostate lobes and the periurethral gland region. There are natural barriers around the transition zone, i.e., the prostatic urethra, the anterior
  • fibromuscular stroma FS and a fibrous plane FP between the transition zone and peripheral zone.
  • the anterior fibromuscular stroma FS or fibromuscular zone is predominantly fibromuscular tissue.
  • a prostatectomy may be indicated, and an alternative to surgery is desired.
  • a device is desired that can ablate the entire prostate or an entire lobe of the prostate via a transurethral approach. In this minimally invasive approach both transition and peripheral zones may be treated.
  • Treatment of an entire peripheral zone may employ a vapor delivery needle that extends up to 2.5 cm from the delivery device shaft located in the urethra. Vapor may be delivered at multiple sites along the path of the needle using ultrasound and needle position sensor guidance.
  • the vapor delivery needle can be capable of controlled movement along its path, including stopping to deliver vapor.
  • Systems and methods for controlling the movement of the needle in digital steps to any location within its reach are disclosed.
  • a blunted needle is disclosed that can penetrate the urethra wall during an initial shallow deployment, but will not penetrate the prostate capsule when the needle is advanced using pulses of current to the needle delivery solenoid.
  • Transurethral vapor delivery devices of the present disclosure are used to deliver urethral vapor delivery devices of the present disclosure.
  • FIG. 1A A transurethral vapor delivery device 100 is illustrated in FIG. 1A in its assembled form, while FIG. IB shows a disassembled view to illustrate the reusable handle portion 102 and a disposable cartridge portion 104 of the vapor delivery device.
  • the handle portion 102 of the vapor delivery device comprises a lumen 103, an electrical cable 106 that plugs into an RF generator (not shown), a grip portion 107, triggers 108 for actuation of flush, needle
  • the calorie output of the vapor delivery device of this invention is related to the power input of the RF generator during therapy delivery through an efficiency coefficient. Calorie output will be consistent from shot to shot if the power delivered is a constant, independent of changes in component values due to the thermal cycling of the device. Calorie output will be consistent from device to device if the input power is always the same for a given therapy, and if the efficiency coefficient is consistent from device to device.
  • Device to device consistency is achieved through consistency of device manufacturing. In addition, consistency improves as the power coupling efficiency approaches 100%, provided that the input power is held constant. In other words, variations in device parameters have a diminishing effect on output as the percentage of the constant input power delivered to the output approaches 100%.
  • the peripheral and transition zones may be treated separately.
  • the vapor delivery needle is long enough to reach cancerous peripheral zone tissues after penetrating through the transition zone. Therapy may be delivered during pulse deployment or pulse retraction to both the peripheral and transition zone tissues.
  • central zone tissues that are impinging upon the urethra may be ablated during a cancer therapy treatment. The central zone may be treated individually, or in some cases after penetration through the transition zone. Central zone and transition zone tissues may both be treated during one needle deployment or retraction.
  • an electromagnetic sensor or transmitter placed at or near the needle tip can facilitate tracking the location of the tip relative to a pre-operative or real time image of the prostate.
  • a second sensor or transmitter may be placed adjacent the ultrasound transducer, so the location and orientation of the needle tip is known relative to the transducer, facilitating autofocus and image enhancements.
  • Tracking of the needle tip can enable robotic steering or navigation of the needle.
  • Advanced vapor therapy delivery systems can robotically advance the needle to a point on an image selected by the operator and deliver a prescribed vapor dose at that site.
  • the tip of the delivery device needle may be steerable using pull wires, as used in other catheter systems.
  • Image guidance with steering enables therapy to be delivered at locations that are optimally separated in a three-dimensional pattern. More exotic steering means may be employed, for example by attaching a magnet to the needle tip, and steering the tip using large, external magnets.
