Study summary

Massive hemoptysis is a serious disease of respiratory system, which seriously endangers the life of patients.

There are obvious difficulties in the treatment of hemoptysis. In the traditional treatment, patients still have the risk of massive hemoptysis and suffocation, and the risk control in the treatment process cannot be ensured.

Intra - airway interventional therapy, especially the hemostatic technique of intra - airway balloon catheter, is an important means to control the risk of hemoptysis.

However, the current intraairway balloon catheter therapy technology is immature, complicated and difficult to operate, and the cost is high. There is a lack of special balloon for hemostasis, and the balloon borrowed for other purposes cannot meet the needs of hemoptysis treatment.

Therefore, it is urgent to develop a new balloon catheter for airway hemostasis, which has simple technical operation, easy to master and popularize, efficient and safe function and structure.

According to this requirement, this project designed and developed hemostatic balloon catheter with multiple functions such as self-guiding, anti-displacement, anti-leakage and detachable rear end, so as to make the treatment of massive hemoptysis more safe and effective, simpler and faster, so as to be widely applied in clinical practice.

Read the detailed description

This study are aimed to investigate the safety and effectiveness of the new intraairway hemostatic balloon catheter in the treatment of massive hemoptysis, as well as the superior efficacy compared with the traditional treatment strategy of massive hemoptysis.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Interventions

  • Devicea New Balloon Catheter for Intraairway Hemostasis

    In the treatment group, the new balloon catheter was inserted in three steps, that is, the tracheoscope was inserted into the airway to remove the blood in the airway and find the target bronchus.The new airway hemostatic balloon catheter was directly inserted through the tracheoscopy biopsy channel, and then directly inflated and fixed after positioning.Then exit the tracheoscope directly to complete.

  • DeviceTraditional Therapy

    A six-step technique was adopted to place the traditional balloon catheter, that is, the tracheoscope was entered to find the target bronchus, the guide wire was inserted through the biopsy channel, the tracheoscope was exchanged to exit the tracheoscope, the catheter was entered through the guide wire exchange, the tracheoscope was re-entered, the catheter was positioned, inflated and fixed, and the tracheoscope was withdrawn.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 26, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
