Essure – Emerging Litigation

Essure – Focus Blocks

Essure is a permanent, less-invasive surgical sterilization procedure for women.  With Essure, a coil designed to induce fibrosis and block the fallopian tubes is placed into each fallopian tube to prevent fertilization. The manufacturer Conceptus Inc., a company owned by Bayer failed to warn of side effects including chronic pain, puncturing of the uterus and/or fallopian tubes, stomach and pelvic device migration, abnormal bleeding, and unplanned pregnancy. Had the manufacturer warned of the risks, patients might have chosen a different form of birth control e.g. hysterectomy, salpingectomy, tubal ligation, tubal fulguration, or application of clips.


Manufacturer: Developed by Conceptus Inc., a subsidiary of Bayer AG.


Device Description: The system consists of two metal coils that doctors implant in each fallopian tube.


Mechanism Of Action:


The insert contains inner polyethylene terephthalate fibers to induce inflammation, causing a benign fibrotic ingrowth, and is held in place by flexible stainless steel inner coil and a dynamic outer nickel titanium alloy coil. Once in place, the ingrowth continues over a period of three months, resulting in durable occlusion or blockage in the Fallopian tubes; the tissue barrier formed is supposed to prevent sperm from reaching an egg. During that intervening three month period, women are advised to use an alternate contraceptive method.


Approval: By FDA it was approved for use in the United States on November 4, 2002.


Serious Risks:

  • Perforation, expulsion, or other unsatisfactory location of the insert
  • Punctured uterine walls
  • Pregnancy and increased risk of ectopic pregnancy
  • Pain, cramping, vaginal bleeding, menstrual pattern changes, light periods at first then longer, heavier periods lasting up to 6–8 weeks due to changing birth control methods to a non-hormonal solution
  • Nausea/vomiting
  • Vasovagal response (fainting)
  • Allergic reaction to the materials
  • Heightened allergic response to other allergens
  • Heavy metal toxicity
  • Itchy, raised rash
  • Brain fog
  • Autoimmune disease symptoms
  • Weight gain
  • Anxiety/depression
  • Hair loss
  • Severe anxiety
  • Numbness of extremities
  • Joint pain
  • Back pain
  • Suicidal thoughts

9.Complications of Essure use:

Specific Focus:

Identify and report cases with the following scenarios:-

  1. No Injuries: Patient had Essure treatment, but did not develop any complications

Missing record communication:

Identify and report on missing medical records

Apart from identifying critical missing records that are important for the case, provide a detailed outline on what records are needed, why we need them, how did we get a clue that these records are missing and whether the records missing are confirmatory/probable. This will also help in following up and retrieving the records.
