A probe is configured with a flushing port and an evacuation port to establish a flow path to remove blood from a resected tissue. The probe comprises a balloon configured to expand and contact the resected tissue to compress filaments and improve access to the underlying blood vessels for coagulation with an energy source. An endoscope can be used to view the tissue, and the balloon may comprise a transparent material or a viewing port to allow imaging of the bleeding tissue through the balloon. The probe may have a light source to illuminate the tissue with a beam oriented at an oblique angle to the tissue surface, which can decrease interference from blood and may allow more localized coagulation of the blood vessel.

A vapor delivery system and method is provided that is adapted for treating prostate tissue. The vapor delivery system includes a vapor delivery needle configured to deliver condensable vapor energy to tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the prostate tissue. The vapor delivery system includes a generator unit and an inductive heating system to produce a high quality vapor for delivery to tissue. Methods of use are also provided.

The lower computer comprises a control unit, a magnetic vibration unit, a magnetoelectric unit and an electrical stimulation unit; the control unit is connected with the magnetic vibration unit, the magnetoelectric unit and the electrical stimulation unit respectively, the magnetic vibration unit is used to generate a vibrating magnetic field acting on a human body, the magnetoelectric unit is used to generate a vibrating rotating magnetic field acting on a human body, and the electrical stimulation unit is used to generate electrical stimulation signals acting on a human body. The device can be used to treat chronic prostatitis.

A medical device may comprise a handle having at least one actuator, a shaft having a proximal end, a distal end, and a lumen extending therebetween, the proximal end connected to the handle, the shaft including a distal articulable section including a distal tip, wherein the distal articulable section is configured to be articulated along a plane, a needle having a delivery lumen, the needle being movably positioned within the lumen of the shaft, and a vapor generator in fluid communication with the delivery lumen.

The invention describes a device comprising at least one emitter of P-waves and/or S-waves, preferably shear waves, more preferably axisymmetric waves, and at least one wave receiver, wherein the receiver or receivers are disposed concentrically, and the disposition of the emitters and receivers allows same to simultaneously come into direct contact with a specimen, the structure of which it is desired to characterise. Also described is a method for characterising the spatial distribution of mechanical parameters of a specimen, based on the emission of shear waves and the subsequent reception thereof.

A medical laser system for outputting laser pulses includes at least one laser cavity, a rotating mirror, a user interface, and a controller. The controller is configured to receive at least one laser parameter associated with a laser pulse output by the system. The controller is configured to determine an average power level of the laser pulse based on the at least one laser parameter associated with the laser pulse. The controller is configured to determine a pulse width modulation (PWM) control signal based on at least one laser parameter. The controller is configured to generate the laser pulse based on the average power level and the PWM control signal, the laser pulse comprising at least one of a first shape, a second shape, or a third shape. Each of the first shape, the second shape, and the third shape of the laser pulse includes different pulse widths.

Apparatus for the treatment of a target tissue with a laser beam in which the target tissue is immersed in a liquid medium within a body lumen. The laser device is configured to provide one or more laser pulses which are configured by a controller to have an energy sufficient to form one or more vapor bubbles in the liquid medium at the distal delivery end of the fiber. The one or more pulses are configured by the controller to: first, cause a vapor bubble to be formed distally of the distal end portion of the endoscope and around the distal delivery end of the optical fiber; second, cause a second bubble to be formed distally of the first bubble; and, third, inflate the second bubble as the first bubble has begun to collapse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the distal delivery end of the fiber and the target tissue.

A system and associated method for altering or destroying tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders. In one aspect, the system includes a device configured to deploy devices for altering the lobes of a prostate.

A transperineal biopsy guide including a guide member and a displacement member supported by the guide member. The guide member may be configured to operably couple with the transrectal probe and may include a distal end, a proximal end opposite the distal end, and a length extending along a longitudinal axis between the distal and proximal ends. The displacement member may be configured to support the access needle and displace the access needle along at least a portion of the length of the guide member between the distal and proximal ends. The access needle may extend into the subcutaneous tissue when the access needle is displaced to the distal end.

A system and method for prostate cancer treatment under local anesthesia includes creating a superficial skin and subcutaneous block in a perineal area of a patient by administering a first anesthetizing agent; creating a deep nerve block under ultrasound guidance by administering a second anesthetizing agent, the second anesthetizing agent infiltrating cavernosal nerve bundle tissue and periprostatic space; and ablating prostate tissue. The office-based method, statistical models and computer generated treatment plans identify and ablate prostate tissue containing cancer through or via the perineum while preserving prostate function, and critical anatomical structures. Multiple technologies are integrated and processed to deliver a safe treatment procedure, under local anesthesia by integrating the information of magnetic resonance imaging and planning the ablative treatment using algorithms that ensure maximal precision in both killing cancerous tissue and preserving healthy tissue along with its corresponding function.
