Catheter with energy emitter for treating lesions in blood vessels
By incorporating an energy emitter into a drug-coated balloon, the delivery of active agents is enhanced using methods such as ultrasound, light energy, or electrical pulses. This solves the problem of uneven drug delivery in angioplasty, achieving effective treatment and stabilization of lesions.

AI Technical Summary
Technical Problem
In the prior art, drug-coated balloons are difficult to deliver drugs consistently and uniformly during angioplasty, leading to restenosis, and some vascular lesions are not suitable for routine treatment.
Method used
A multimodal catheter is used, combined with a drug-coated balloon and an energy emitter. The energy emitter emits energy towards the lesion site when the active agent is released, to enhance the delivery or uptake of the active agent, including through ultrasound, light energy or electrical pulses, to promote lesion healing and stabilization.
Benefits of technology
It improves the uniformity and efficiency of active agent delivery to the lesion site, reduces inflammation, promotes lesion healing and stabilization, and inhibits restenosis.

Abstract
本公开提供了一种用于通过增强活性剂到血管中的病变治疗部位中的摄取来治疗该病变治疗部位的多模态导管（10），该多模态导管包括药物涂布的球囊（20）和能量发射器（24），诸如用于生成电脉冲的超声换能器或电极。该能量发射器从邻近该导管主体的远侧端部向该病变治疗部位发射能量，以在该活性剂被从该药物涂布的球囊释放时增强该活性剂在该病变治疗部位处的递送或摄取。另一导管（110）包括能量发射器（124），该能量发射器适于改变病变以减少炎症并促进该病变的愈合和稳定化，从而抑制该病变从血管壁分离或移出。该导管还可包括药物涂布的球囊。
