Abstract

An introducer sheath assembly having: a handle portion including a distal end and a proximal end; and an introducer sheath extending outwardly from the distal end of the handle portion, the introducer sheath including a a device lumen configured to slidably receive a corresponding device, a guidewire lumen configured to slidably receive a corresponding guidewire, and disposed radially outward from the device lumen At least one steering cable is disposed within the at least one steering cable lumen, and the handle portion includes at least one steering assembly for modifying tension of at least one of the at least one steering cable.

Description

technical field [0001] The present disclosure relates generally to medical devices, and more particularly, to vascular access sheaths and catheters. Background technique [0002] Minimally invasive catheter-based treatments are increasingly being developed that allow physicians to provide treatment to patients whose existing comorbidities may prevent them from performing desired but more invasive procedures. Surgery. Catheter-based procedures, such as cardiac ablation and balloon valvuloplasty, involving piercing / traversing of the interatrial septum, have become commonplace over the past 30+ years. Over the past 5 to 10 years, new structural heart procedures (such as transcatheter valve repair / replacement and left atrial appendage closure) have gained regulatory approval and have become routinely performed in cardiac catheterization laboratories or hybrid operating rooms An increasingly common procedure performed. With the advent of these techniques, there has been an inc...
