摘要:
A device for heating tissue, comprises a housing sized for insertion through a naturally occurring body orifice to a target location within a lumen and a heat generating element within the housing focusing thermal energy on a target area separated from an outside of the housing so that, when the housing is in the target location, the target area is within tissue surrounding the lumen at a predetermined depth from a lumenal wall in combination with a temperature sensing element sensing data corresponding to a temperature of tissue in the target area and a processor controlling the heat generating element in response to the data sensed by the sensing element.

A support device includes a support member and a frame member. The support member has a body portion and an elongated arm extending from the body portion. The elongated arm has a width smaller than a width of the body portion of the support member. The body portion is configured to help support an anatomical structure located in a pelvic region of a patient. The frame member is coupled to the support member and comprised of a shape memory alloy.

A method of treating tissue comprises introducing into a hollow organ a support device and, after insertion, arranging the support device into a non-yielding configuration substantially filling the hollow organ and substantially preventing walls of the hollow organ from moving inward in combination with inducing contraction of the hollow organ around the support device to cut off blood flow through at least a portion of the walls of the hollow organ and removing the support device after blood flow has been cut off for a predetermined time. A system to treat tissue comprises a support device which, in a first configuration, is sized and shaped for insertion into a hollow organ and an expansion mechanism for expanding the support device from the first configuration to a second configuration in which the support device substantially fills the hollow organ providing a non-yielding support so that, if the hollow organ is contracted around the support device, blood flow through at least a portion of a wall of the hollow organ is cut off.

A neuromodulation system, comprises an implantable electrode which is implanted within a body adjacent to a target nerve structure to which electric energy is to be applied via the electrode and a connection port which is implanted in the body with a proximal surface thereof substantially flush with an outer surface of a skin of the body, the connection port including a device interface for electrically connecting to an external device which remains external to the body in combination with an electric line extending from the device interface to the electrode for carrying electric energy from the external device to the electrode and a cover selectively closing an opening of the external surface of the implanted connection port.
摘要:
A method of ablating tissue, comprises anchoring a first electrode at a first location in a target portion of tissue, deploying a second electrode at a second location in the target portion of tissue and applying current between the first and second electrodes to ablate a first ablation portion of tissue in combination with moving an insulative cover relative to the first electrode to move a conductive portion of the first electrode to a third location within the target tissue, the third location being further from the second location than the first location, moving the second electrode to a fourth location within the target tissue, the fourth location being further from the first location than the second location and applying current between the conductive portion of the first electrode and the second electrode to ablate a second ablation portion of tissue surrounding the first ablation portion of tissue.
摘要:
A tissue ablation device comprises first and second electrodes of opposite polarities, the first electrode being mounted to a first elongated member for movement relative to the second electrode for separation therefrom by a desired distance. A method of ablating a tissue comprises inserting first and second electrodes to desired initial positions relative to a tissue mass to be ablated and applying electrical energy to the first and second electrodes to ablate a first portion of tissue between the first and second electrodes in combination with the step of applying electrical energy to desired second positions separated from the desired initial positions by a distance selected to transfer electrical energy around the first portion of tissue through a second portion of tissue to be ablated, the second portion of tissue surrounding the first portion of tissue.
摘要:
Embodiments include a method of performing a medical procedure in a patient. The method includes inserting a first working instrument and a second working instrument through an opening in the patient, creating an incision in body tissue inside the patient using at least one of the first and second working instruments, and advancing the second working instrument through the incision to position the second working instrument at a work site inside the patient. The method also includes positioning the first working instrument at the work site without advancing the first working instrument through the incision and performing a procedure at the work site inside the patient using the first and second working instruments.

摘要:
A system and method for surgery on a hollow organ comprises a source of a biocompatible gellable fluid in a flowable state and an insertion device for introducing the gellable fluid into a hollow organ of a patient, the gellable fluid transitioning from the flowable state to a gel-like state to form a gel mass within the hollow organ to support a wall of the hollow organ in combination with a state control apparatus for transitioning the gel mass from the gel-like state to the flowable state and a removal device for removing from the hollow organ the gellable fluid in the flowable state.
摘要:
A medical device allows movement control of a distal end portion of the medical device and is adapted for one-handed operation. The medical device is capable of omni-directional control of the distal end portion of the device. The device has an elongated member including a deflectable portion at a distal end portion of the elongated member. The device also has a control portion disposed on the elongated member. This control portion can be a handle for one-handed use by an operator of the medical device. The control portion comprises an elastic element and a flexible element. Angular movement of a first portion of the control portion with respect to a second portion of the control portion results in amplification of that angular movement in the deflectable portion of the device.
