简要总结

The investigators have created a device designed to make it easier to insert pharmaceutical implants under the skin. The device uses a blood pressure cuff to hold the skin on a person's arm in place while a mechanical guide places implants underneath the skin. This device may prevent implants from being embedded too deeply.

The investigators are performing this study to determine the safety and efficacy of the device for use in adult women. The study will determine if the implants are placed accurately under the skin (in the sub-dermal layer). It will also assess if the device causes any discomfort or last pain from use.

详细描述

Subcutaneous contraceptive implants are one of the preferred methods of long-term contraception by the World health Organization and ministries of health in low- and middle-income countries. These implants offer between three and five years of protection (allowing women to safely space pregnancies and thereby reduce maternal and infant mortality), are 99.95% efficacious, allow women to return to fertility quickly when removed, requires no daily/monthly effort on the part of the woman, and cause minimal side effects in comparison to other methods. However, availability of contraceptive implants in rural areas is limited due to the skill necessary to administer them safely and accurately.

The investigators have created a device designed to make it easier to insert pharmaceutical implants under the skin. The device uses a blood pressure cuff to hold the skin on a person's arm in place while a mechanical guide places implants underneath the skin. This device is designed to prevent implants from being embedded too deeply.

In this trial, the investigators will use the implant insertion device with a placebo sub-cutaneous implant. Implants will be inserted with the device and the accuracy of the placement will be assessed through palpation and ultrasound depth measurements. This data will allow the investigators to assess whether the device ensures accurate insertions of sub-cutaneous implants.

结局指标

主要结局

Implant Depth: Distal End

时间窗: Up to 60 minutes after insertion

Depth of distal end of implant beneath the skin after insertion. Measured via high frequency ultrasound with linear probe. Measured in centimeters below skin surface. Measurements will be aggregated via mean and standard deviation.

Implant Depth: Proximal End

时间窗: Up to 60 minutes after insertion

Depth of distal end of implant beneath the skin after insertion. Measured via high frequency ultrasound with linear probe. Measured in centimeters below skin surface. Measurements will be aggregated via mean and standard deviation.

Implant Palpability

时间窗: Up to 15 minutes after insertion

A binary (yes/no) assessment of whether the implant is palpable by a physician under the skin after insertion. Measurements will be aggregated based on percent of implants that are palpable.

次要结局

  • Presence of Bruising(7 to 14 days after insertion)
  • Number of Participants With Bruising(Up to 15 minutes after insertion.)
  • Number of Participants With More Bleeding Than Typical(Up to 10 minutes after insertion)
  • Number of Participants With Signs of Infection(21 to 28 days after insertion)
