A drug coated balloon catheter
By introducing biodegradable microneedles and staggered pressure-absorbing elements into the drug-coated balloon catheter, combined with an adhesion fixation layer and a rapid drug release layer, the problem of uneven adhesion between the drug-coated balloon and the irregular lesion vessel wall is solved, achieving deep penetration and uniform distribution of drugs and improving the therapeutic effect.

AI Technical Summary
Existing drug-coated balloons cannot achieve optimal adhesion and uniform compression to irregularly diseased vessel walls during expansion, resulting in uneven drug distribution and treatment blind spots.
Design a drug-coated balloon catheter comprising a surface-covered biodegradable microneedles and an internal elastic balloon, driven by interleaved active pressure-resistant elements and control cables, combined with an adhesion fixation layer and a rapid drug release layer to promote deep drug penetration and uniform distribution.
It improves the penetration efficiency and targeting depth of drugs in the blood vessel wall, reduces long-term foreign body residue and inflammatory stimulation, ensures uniform drug delivery in irregular lesion areas, and reduces treatment blind spots.
