FD-2, an Anticervical Stenosis Device for Patients Undergoing Radical Trachelectomy or Cervical Conization

Area of Science:

• Gynecologic Oncology
• Biomaterials Science
• Medical Device Development

Background:

• Radical trachelectomy for cervical cancer can lead to uterine cervical stenosis.
• Existing methods for preventing stenosis post-surgery are limited.
• There is a need for effective devices to manage post-surgical cervical complications.

Purpose of the Study:

• To introduce FD-2, a novel anticervical stenosis device.
• To evaluate the safety and preliminary utility of FD-2 in patients undergoing radical trachelectomy.
• To assess the efficacy of FD-2 in preventing cervical stenosis and dysmenorrhea.

Main Methods:

• FD-2 was developed using ethylene-vinyl acetate copolymers.
• Material safety was assessed via tensile and extractables/leachables testing.
• FD-2 was indwelled in three cervical cancer patients during radical trachelectomy for utility evaluation.

Main Results:

• FD-2 passed all safety tests, confirming its suitability as a medical device.
• Device application and removal averaged under 10 seconds.
• No FD-2-associated complications were reported; patients showed no cervical stenosis or dysmenorrhea at follow-up.

Conclusions:

• FD-2 is a novel, safe, and effective device for preventing cervical stenosis after radical trachelectomy.
• The device demonstrated ease of use and a favorable safety profile in preliminary trials.
• FD-2 offers a promising solution for managing a significant complication of cervical cancer treatment.
