SELF-ORIENTING ENDOVASCULAR DELIVERY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240050253 titled 'SELF-ORIENTING ENDOVASCULAR DELIVERY SYSTEM
Simplified Explanation
The abstract describes an elongate delivery shaft assembly that includes an outer covering shaft and an inner support shaft. When the delivery shaft assembly is unconstrained, a stent-graft can be removably constrained in a radially-compressed delivery state along a distal end portion of the delivery shaft assembly, between the outer covering shaft and the inner support shaft. The delivery shaft assembly is shaped to define a self-orienting portion, which includes proximal and distal curved portions and at least one point of inflection on a central longitudinal axis of the assembly. The smallest radii of curvature of the proximal and distal curved portions, measured at the central longitudinal axis, are each between 2.5 and 12 cm.
- The invention is an elongate delivery shaft assembly for delivering a stent-graft.
- The assembly includes an outer covering shaft and an inner support shaft.
- The delivery shaft assembly can be unconstrained, allowing the stent-graft to be removably constrained in a radially-compressed delivery state.
- The assembly is shaped to define a self-orienting portion with proximal and distal curved portions and at least one point of inflection on the central longitudinal axis.
- The smallest radii of curvature of the proximal and distal curved portions, measured at the central longitudinal axis, are each between 2.5 and 12 cm.
Potential applications of this technology:
- Delivery of stent-grafts in medical procedures, such as endovascular repair of aneurysms or other vascular conditions.
- Minimally invasive procedures where a stent-graft needs to be accurately positioned and deployed.
Problems solved by this technology:
- Facilitates the delivery of stent-grafts in a radially-compressed state, allowing for easier insertion and navigation through the body.
- The self-orienting portion of the assembly helps to ensure proper alignment and positioning of the stent-graft during deployment.
Benefits of this technology:
- Improved accuracy and control during stent-graft delivery, reducing the risk of complications or the need for additional procedures.
- Minimizes trauma to the patient by enabling a less invasive approach.
- Allows for the delivery of stent-grafts with varying sizes and configurations, increasing the versatility of the assembly.
Original Abstract Submitted
an elongate delivery shaft assembly () includes an outer covering shaft () and an inner support shaft (). when the delivery shaft assembly () is unconstrained and a stent-graft () is removably constrained in a radially-compressed delivery state along a distal end portion () of the delivery shaft assembly (), radially between the outer covering shaft () and the inner support shaft (): (a) the delivery shaft assembly () is shaped so as to define a self-orienting portion (), which (i) is shaped so as to define at least proximal and distal curved portions (a, b), the proximal curved portion (a) disposed more proximal than the distal curved portion (b), and (ii) at least one point of inflection () on a central longitudinal axis () of the delivery shaft assembly () longitudinally between the proximal and the distal curved portions (a, b), and (b) respective smallest radii of curvature of the proximal and the distal curved portions (a, b), measured at the central longitudinal axis (), are each between 2.5 and 12 cm.
