About this study
Evaluation of efficacy and safety of using Aqueduct -100 - Cervical Dilator Device
Read the detailed description
There are predominantly two major dilatation techniques that are employed in dilating the cervix. The first technique uses expansible dry solid material, such as laminaria (seaweed) is inserted into the cervix in its dried stiff form. In the cervix it comes into contact with body fluids that cause the laminaria to swell and enlarge the cervical cavity. The second more widespread procedure, involves the use of series of solid, rod like instruments of graduated diameter used in serial fashion by the physician (Hegar dilators). The physician first inserts a rod like dilator and replaces it with the dilator of next higher diameter. This procedure continues until adequate dilatation occurs.
The Problem is that each of the above-mentioned methods has its shortcomings: the use of the laminaria method (rarely done) requires preliminary patient visit, for insertion of the laminaria rod and is extremely slow and typically involves often as much as 10-12 hours for a significant amount of dilatation to occur.
The use of rod-like instruments (Hegar) requires general or regional anesthesia, when local anesthetics are used, the patient nevertheless frequently experiences a great amount of discomfort from the procedure. The mechanical dilatation of the cervix demands a large amount of longitudinal force that may damage or even puncture the cervix and the uterus.
Aqueduct 100 is a catheter for use in dilating various body cavities and especially the human cervix. The device will enable continuous, fast and safe dilatation of the cervix to a pre-determined diameter as a pre-procedure to intrauterine surgeries.

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of patients with dilation of cervix to the diameter needed to perform the intrauterine procedure using Aqueduct-100 device. (time frame: Through study completion, approximately 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02941211, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Oct 2016.
