Therapeutic ultrasonic catheter for delivering a uniform energy dose
TL;DR: A catheter (30) is a method for treating a target region in a body lumen comprising directing a uniform dose of ultrasonic energy from an interior of the lumen, wherein the dosage of ultrasound energy received at any one point along the length varies by no more than plus or minus 6 decibels as discussed by the authors.
Patent
Ultrasonic enhancement of drug injection
TL;DR: In this article, a method of enhancing cellular absorption of a substance delivered into a target region of a patient's body, comprising of delivering the substance to the target region, and directing vibrational energy, was proposed.
PatentDOI
Methods and apparatus for uniform transcutaneous therapeutic ultrasound
TL;DR: In this paper, a wide beam ultrasound delivery system providing a uniform exposure field is used to enhance the uptake of injected substances and/or enhance the transfection of DNA in the tissues of human subject, or reduce the amount of vascular intimal hyperplasia in human subjects following vascular injury.
PatentDOI
High output therapeutic ultrasound transducer
TL;DR: In this article, a therapeutic ultrasound delivery system, including a catheter body (17), a plurality of axially spaced-apart cylindrical vibrational transducers (14), was presented.
Patent
Methods and kits for the inhibition of hyperplasia in vascular fistulas and grafts
TL;DR: In this paper, a method for inhibiting hyperplasia at an anastomotic junction of a vascular fistula or vascular graft comprises exposing the junction to vibrational energy at a mechanical index.
