Devices and methods for a totally percutaneous collapsible aortic punch

A totally percutaneous device for removing calcium deposits from an aortic valve, comprising:

• a collapsible filter umbrella positioned coaxially around at a distal end of a primary tube;
• a punch system including a collapsible female element positioned coaxially around the primary tube proximal to the filter umbrella and spaced apart from a collapsible male element positioned coaxially around the primary tube proximal to the female element;
• a first removable cover positioned coaxially around the primary tube for covering and uncovering the collapsible male element such that the male element is collapsed when covered by the first removable cover;
• a second removable cover positioned coaxially around the primary tube for covering and uncovering the collapsible female element such that the female element is collapsed when covered by the second removable cover;
• a third removable cover positioned coaxially around the primary tube for covering and uncovering the collapsible filter umbrella such that the filter umbrella is collapsed when covered by the third removable cover;
• and
• a control system positioned at the proximal end of the primary tube and controlling the first removable cover, second removable cover, and third removable cover to cover and uncover the male element, the female element, and the filter umbrella, respectively,
• wherein the control system includes a punch control driver actuating the uncollapsed male element and the uncollapsed female element to advance and retreat relative to one another within the aortic valve.

A method of a totally percutaneous aortic punch for removing calcium deposits from an aortic valve, comprising:

• inserting a device through an aortic valve, wherein the device has a collapsible filter umbrella for catching debris from operation of the device and a collapsible punch system for perforating the aortic valve;
• positioning the punch system within the native aortic valve, wherein a male element and a female element of the punch system are collapsed to avoid inadvertent damage to surrounding tissue, and wherein the male element and female element are on positioned on opposite sides of native aortic valve;
• positioning the collapsed filter umbrella in an aorta down-stream of blood flow through the aortic valve, such that the filter umbrella allows blood to pass beyond the aorta and catches debris;
• uncompressing the collapsed male element, female element, and filter umbrella;
• perforating the aortic valve to remove calcium deposits from the aortic valve;
• and
• leaving a ring of calcium deposits along the circumference of the native aortic valve.

A collapsible punch system for totally percutaneous removal of calcium deposits from an aortic valve, comprising:

• a male element having a center ring and a plurality of symmetrical spokes increasing in width toward a common circumference, the male element being deformable to a closed conical shape in which the spokes form a continuous ring at the circumference, wherein the spokes are collapsible to a cylinder shape when compressed and return the conical shape when uncompressed;
• a female element having a center ring and a plurality of symmetrical spokes increasing in width toward a common circumference, the female element being deformable to a closed conical shape in which the spokes form a continuous ring at the circumference, wherein the spokes are collapsible to a cylinder shape when compressed and return the conical shape when uncompressed;
• and
• a punch control element configured to move the collapsible male element in relation to the collapsible female element when the male element and the female element are uncompressed,
• wherein the female element receives the male element.
