    摘要: A cannula and method provide manually manipulable orientation of a dissection probe carried eccentricity on the cannula for rotational and translational positioning relative to the field of view of an endoscope at a distal end of the cannula. Rotation of the cannula at fixed axial position relative to the endoscope, and rotational and translational positioning of the dissection probe relative to the distal end of the cannula provide wide-area access within the surgical site for bluntly dissecting connective tissue surrounding a vessel of interest being harvested.

    摘要: A method and system for removing an organ or piece of tissue severed from its supporting tissue within a patient's body cavity, such as the abdominal cavity, which includes an elongated expandable tubular member with a sealed interior. In one preferred embodiment for morcellation, means are provided within the sealed interior to tear or cut off tissue fragments from the organ or tissue which are small enough to pass out of the patient's body cavity through an inner lumen of an exit trocar sheath disposed within the patient and in communication with the body cavity. The organ or piece of tissue is placed within an inner lumen defined by the sealed interior through an opening provided in a leading portion of the elongated expandable tubular member. The organ or piece of tissue is fragmented into smaller pieces which are withdrawn from the patient's body cavity by the passage of the morcellation system through the inner lumen of the exit trocar sheath. In one embodiment of the morcellation system, one or more elongated cutting strips are disposed within the inner lumen defined by the sealed interior and secured to the lining to cut or tear the tissue into small fragments. In another embodiment of the invention one or more elongated helical ribbons are provided to cut or tear the tissue into small fragments.

    摘要: A deflectable, flexible device includes an elongate body, a convoluted tip portion at a distal end of the elongate body, and a lumen to receive one or more wires. The convoluted tip portion includes an electroformed pleated region which is formed by electrodepositing a metal on a mandrel having a pleated region. The convoluted tip portion may be hermetically sealed to permit repeated sterilization. The electroformed pleated region may include one or more fluid emission orifices. The convoluted tip portion extends or bends in response to fluid pressure manipulation, contact with tissue, manipulation with an internal spring or wire, or by a user pushing, pulling, or twisting the catheter directly or via an introducer sheath or the like. The convoluted tip portion may further include an RF ablation element or other energy-driven technique to create continuous linear lesions or a sensing element.

    摘要: A tissue ablation system facilitates lesioning deep tissue while preventing damage to superficial tissue and includes a probe having a distal end portion, at least one transducer carried on the distal end portion, and at least one acoustically transparent heat removal element thermally coupled to a target tissue within the beam path of the transducer. The transducer delivers acoustic energy to the tissue through the heat removal element in order to ablate the tissue; the heat removal element removes sufficient thermal energy from the tissue volume to prevent thermal necrosis in superficial tissue. The heat removal element may be a heat sink or a convective element. An optional temperature sensor provides advisory data to a practitioner and/or is coupled to a feedback control system operable to control delivery of acoustic energy to the tissue and/or a rate of thermal energy removal therefrom.

    摘要: A system for delivering a probe into a body part to perform a therapeutic or diagnostic procedure therein which includes an elongated probe device which is disposed within a protective sheath and which has a rotary drive unit connected to its proximal extremity to rotate the probe about its longitudinal axis, preferably at a rate above 50 rpms while applying axial pressure thereto to cause the distal end of the probe to penetrate through the patient's tissue to a desired location in the body part where the procedure is to occur. In a presently preferred embodiment, the probe is an optical fiber which is delivered into a male patient's prostate gland through the patient's prostatic urethral wall. The optical fiber is optically connected to a source for laser energy (815 nm) which is emitted from the distal end of the optical fiber to ablate prostatic tissue surrounding the distal end. A sheath is disposed about the optical fiber to support the shaft thereof and to minimize damage to the working channel of a cystoscope through which the device is usually advanced to reach the desired location within the patient's prostatic urethra.

    摘要: A system for ablating tissue includes a catheter having an elongate body, with at least one ablation element (e.g., RF electrode) and at least one acoustic transducer located within the body's tip region. The transducer receives acoustic signals from proximate the tip region. The system also includes a monitoring unit coupled to the transducer to interpret the received acoustic signals as data regarding at least one therapeutic parameter (e.g., pre-pop detection, lesion making progress, tissue interface detection, tissue contact force, tissue contact establishment, bubble spatial distribution, bubble depth, bubble size, bubble size distribution, tissue interface distance, tissue interface position, tissue attenuation, tissue thickness, lesion spectral fingerprint). The monitoring unit is operable to provide feedback to a practitioner, such as graphical, audible, and/or haptic output of sensed data, and may also be operable to control operation of the at least one ablation element in response thereto.
