Abstract

Abstract The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by imposing a secondary shape on a resilient structure, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. The resilient structure is then restrained by the walls of the fallopian tube, imposing anchoring forces as it tries to resume the secondary shape.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 84 words
A method for sterilizing a female patient using an elongated instrument assembly having a distal end, said method comprising the steps of: inserting the distal end of the elongated instrument assembly transcervically into the female patient, the distal end of the elongated instrument having a detachable body; applying tissue damaging energy from the body to a surrounding tissue; detaching the body from the distal end of the elongated instrument assembly; and removing the remaining portion of the elongated instrument assembly from the female patient.
Claim 2
Independent Claim 84 words
A method for sterilizing a female patient using an elongated instrument assembly having a distal end, said method comprising the steps of: inserting the distal end of the elongated instrument assembly transcervically into the female patient, the distal end of the elongated instrument having a detachable body; applying tissue damaging energy from the body to a surrounding tissue; detaching the body from the distal end of the elongated instrument assembly; and removing the remaining portion of the elongated instrument assembly from the female patient.
Claim 3
Dependent Claim 13 words
The method of claim 1 wherein the tissue damaging energy comprises electrical energy.
Claim 4
Independent Claim 63 words
A method comprising: inserting a catheter having an electrically conductive surface assembly mounted on a distal end of the catheter through the vagina and the cervical canal of the patient and into the uterus of the patient; advancing the detachable assembly into the uterotubal junction of the patient; applying electrical energy to the detachable assembly; detaching the catheter from the detachable electrode assembly.
Claim 5
Independent Claim 63 words
A method comprising: inserting a catheter having an electrically conductive surface assembly mounted on a distal end of the catheter through the vagina and the cervical canal of the patient and into the uterus of the patient; advancing the detachable assembly into the uterotubal junction of the patient; applying electrical energy to the detachable assembly; detaching the catheter from the detachable electrode assembly.
Claim 6
Independent Claim 79 words
A method of sterilizing a female, said method comprising the steps of: (a) providing an elongated instrument assembly having a distal end portion; (b) inserting the distal end portion of the instrument assembly into the patient's uterotubal junction; (c) operating the instrument assembly to deliver electrical energy from the instrument to the uterotubal junction; (d) detaching the distal portion of the instrument from the remainder of the instrument; (e) removing the remaining portion of the instrument from the patient.
Claim 7
Independent Claim 79 words
A method of sterilizing a female, said method comprising the steps of: (a) providing an elongated instrument assembly having a distal end portion; (b) inserting the distal end portion of the instrument assembly into the patient's uterotubal junction; (c) operating the instrument assembly to deliver electrical energy from the instrument to the uterotubal junction; (d) detaching the distal portion of the instrument from the remainder of the instrument; (e) removing the remaining portion of the instrument from the patient.
Claim 8
Independent Claim 78 words
A method of sterilizing a female, said method comprising: providing a catheter having a body releasably mounted on the distal end of the catheter; and providing an energy source operably connected to the body and capable of energizing the body; inserting the catheter into the uterus of the female, and inserting the body into a uterotubal junction of the female; operating the energy source to energize the body; releasing the body from the distal end of the catheter.
Claim 9
Independent Claim 78 words
A method of sterilizing a female, said method comprising: providing a catheter having a body releasably mounted on the distal end of the catheter; and providing an energy source operably connected to the body and capable of energizing the body; inserting the catheter into the uterus of the female, and inserting the body into a uterotubal junction of the female; operating the energy source to energize the body; releasing the body from the distal end of the catheter.
