Abstract
An implantable stent for treating hypertension, the stent having a non-circular cross-section so as to reshape the artery in which the implant is deployed so as to increase strain in the arterial walls to amplify strain signals in the arterial walls by the baroreceptors of the artery. The stent can further include pulsatility enhancing windows of the implantable frame to enhance pulsatility of the vessel wall subsequent implantation.
Claims20
An implant for treating hypertension in a patient, the implant comprising:
- a stent having cells defined by struts such that the stent has a collapsed profile configuration for intravascular delivery to an artery proximate baroreceptors and an expanded configuration in which the struts contact arterial walls of the artery in which the stent is deployed;
- wherein the stent in the expanded configuration has a non-circular cross-section so as to reshape the artery in which the implant is deployed so as to increase strain in the arterial walls to amplify strain signals in the arterial walls by the baroreceptors;
- and
- wherein the stent is configured such that a transverse dimension across the stent during diastole is smaller than the transverse dimension during systole, thereby amplifying pulsatility of the arterial walls to enhance a response of the baroreceptors.
A method of treating hypertension in a patient comprising:
- delivering a stent defined by struts in a collapsed profile configuration through vasculature of the patient to an artery of the patient;
- deploying the stent to an expanded configuration proximate baroreceptors in the artery so that the struts contact arterial walls of the artery, wherein the stent in the expanded configuration has a non-circular cross-section so as to reshape the artery in which the implant is deployed so as to increase strain in the arterial walls to amplify strain signals in the arterial walls by the baroreceptors;
- and
- amplifying pulsatility of the arterial walls to enhance a response of the baroreceptors by the stent after implantation by virtue of a transverse dimension across the stent during diastole being smaller than the transverse dimension during systole.
