Abstract:
A surgical system includes an endoscope (3), a pair of end effectors (26,28) provided on the outside of the distal end of an endoscope (on-scope), in which one end effector is rotatable or otherwise movable relative to the second end effector and in which such movement is effected via control elements (18) which do not extend through a lumen of the endoscope, and another instrument extending through the lumen (7) of the endoscope (through-scope), and which preferably also has a pair of end effectors. The on-scope device may be clamping jaws, needle passers, clip appliers, staplers , and releasable hemoclips, among other end devices. The through-scope end effectors may be graspers and clip appliers, among other end effectors.
Abstract:
A sphincter treatment apparatus includes an elongated member (18) having at least one lumen including an inflation lumen, a basket assembly (20) with first, and second arms (21). The basket assembly (20) is coupled to the elongated member (18), has deployed, and non-deployed configurations. An inflatable member (25) is coupled to the elongated member (18), and positioned in an interior of the basket assembly (20). The inflatable member (25) has deployed, non-deployed states, and is coupled to the inflation lumen. In the deployed state, the inflatable member (25) expands the basket assembly (20) to its deployed configuration. A first energy delivery device (22) is positioned in the first arm, and advanced therefrom. A second energy delivery device (22) is positioned in the second arm, and advanced therefrom.
Abstract:
Unified systems and methods enable control of the use and operation of a family of different treatment devices, to treat dysfunction in different regions of the body.
Abstract:
Multiple electrodes are coupled together in mono-polar or bipolar arrays to form lesion patterns in tissue regions at or near a sphincter. A controller (52) couples the electrodes to a generator (38) so that a single power channel serves more than a single electrode.
Abstract:
A sphincter treatment apparatus includes an energy delivery device introduction member including a plurality of arms. Each arm has distal and proximal sections. The distal sections of the arms are coupled as are the proximal sections of the arms. The energy delivery device introduction member is configured to be introduced in the sphincter in a non-deployed state, expand to a deployed stte to at least partially expand the sphincter. A plurality of energy delivery devices are coupled to the energy delivery device introduction member. At least a portion of the plurality of energy delivery devices are controllably introducible from the energy delivery device introduction member into the sphincter.
Abstract:
A method of treating a sphincter provides a treatment apparatus that includes an expandable device coupled to an introducer distal portion and an energy delivery device. The expandable device includes a first arm and a second arm each with proximal and distal section. The expandable member has a non-deployed configuration and a deployed configuration when the first and second arm distend away from each other. The expandable device is at least partially introduced in the sphincter. At least a portion of the energy delivery device is advanced from the expandable device into an interior of the sphincter. Sufficient energy is delivered from the energy delivery device to create a desired tissue effect in the sphincter. The expandable device is then removed from the sphincter.
Abstract:
An apparatus to treat a sphincter includes a catheter means including a catheter means distal portion means. An energy delivery device means is coupled to the catheter means and includes a tissue piercing distal end. The energy delivery device means is configured to pierce a sphincter exterior surface, advance a sufficient distance in an interior of the sphincter to a tissue site, deliver energy to the tissue site and create controlled cell necrosis of the sphincter in order to reduce a frequency of sphincter relaxation. A cable means is coupled to the energy delivery device means.
Abstract:
A method of treating a sphincter that provides an expandable basket structure with a first energy delivery device. The basket structure is introduced in a sphincter. The first energy delivery device is advanced from the basket structure into an interior of the sphincter. Sufficient energy is delivered from the first energy delivery device to create a desired tissue effect in the sphincter. Thereafter, the basket structure is removed from the sphincter. Needle electrodes exiting the basket structure can penetrate the tissue thus delivering energy at targeted sites.
Abstract:
A method of treating a sphincter provides a sphincter electropotential mapping device with a mapping electrode. The sphincter electropotential mapping device is introduced into at least a portion of the sphincter. Aberrant myoelectric activity of the sphincter is detected. Energy is delivered from the sphincter electropotential mapping device to treat the aberrant myoelectric activity of the sphincter. Needle electrodes exit the mapping structure, penetrate the surrounding tissues, thus delivering energy topically.
Abstract:
A device for heat treatment of body tissue, comprising a catheter (12), which is insertable in the body and is equipped with an expandable fluid receptacle (11). The fluid receptacle (11) contains heating means (10) for convective heating of fluid contained in the receptacle (11) and, thus, heating of the tissue in an area of treatment located in the environment surrounding the fluid receptacle (11). The heating device (10) is connected to an energy supply unit (14) located outside of the body.
