Definitions

  • the present technology is generally related to an automated indeflator for a medical balloon device with pre-loaded compliance data for operating the indeflator and/or a closed-loop feedback control system with apposition monitoring.
  • An indeflator is a device that controls the inflation and deflation of medical balloons used in procedures such as angioplasty, stent placement, or balloon dilation. These balloons and stents are commonly used to open up narrowed or blocked blood vessels, for example.
  • an indeflator is connected to a balloon catheter, which is positioned at the site of a lesion or narrowing in the blood vessel.
  • the clinician operates the indeflator to deliver a controlled amount of inflation fluid (such as saline or contrast dye) into the balloon.
  • This inflation expands the balloon, which compresses the plaque or blockage against the vessel wall and opens the vessel lumen.
  • the indeflator often includes pressure monitoring capabilities, allowing the clinician to monitor the pressure within the balloon during inflation. This helps ensure that the balloon is inflated to the appropriate pressure level, avoiding over-inflation, which could lead to vessel injury or rupture, and under-inflation, which could lead to ineffective treatment.
  • a stent is also placed at the lesion during the angioplasty procedure.
  • a stent is received over the deflated balloon and delivered to the lesion site, whereupon the clinician inflates the balloon to expand and deploy the stent.
  • the balloon is inflated to a selected pressure to ensure that the balloon expands sufficiently to achieve suitable or optimal apposition against the vessel wall. Poor apposition, where the stent does not fully expand or does not make proper contact with the vessel wall, can lead to several complications, such as residual stenosis, stent thrombosis, restenosis, and/or tears in the vessel wall at the edges of the stent.
  • the balloon pressure chosen by the clinician may be determined based on factors such as the size and ty pe of the stent, the diameter of the target vessel, and the presence of calcified lesions or other challenging anatomical features.
