Novel Sheath Designs in a Transseptal Access System
JHU REF: C12321
Invention Novelty: This technology comprises of a novel sheath design and a transseptal access system for performing transseptal punctures during invasive cardiac procedures.
Value Proposition: Transseptal punctures are required to be performed in various invasive cardiac procedures. While they are accompanied by a number of complications, they are most difficult in patients with atrial septal aneurysm. Because the septal wall in these patients is extremely pliable there is a huge risk of cardiac wall perforation during invasive procedures. There are no tools available that can address this safety issue today. This novel technology addresses this need by means of a novel sheath design that can be used effectively lead to safer transseptal access in these patients. Advantages of this technology include:
· Novel sheath design employing different techniques for achieving a firm hold of the sheath over the aneurysmal tissue so that the needle can be deployed in the right place for performing the puncture
· Can be used for patients with other septal wall defects
· Lowers the risk of performing transseptal punctures in patients with weaker septal walls
Technical Details: Johns Hopkins researchers have developed a transseptal access system with novel and specialized venous sheath designs that can be used for a more effective and risk-free transseptal access in patients with atrial septal aneurysms. The sheath utilizes different techniques in order to secure the aneurysmal fossa ovale against the sheath surface. Once the sheath is secured firmly in place it can be retracted along with the fossa ovale in order to move it away from the left atrial free wall region. Following this, the dilator and needle can be guided to allow a safe puncture of the fossa ovale without any damage to the free atrial wall.
Looking for Partners: To develop and commercialize the technology as a highly safe and effective transseptal access system for patients with atrial septal aneurysm and other septal defects.
