Patents by Inventor Sameer D. Pai

Sameer D. Pai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11617861
    Abstract: A catheter with three distinct compression resistance coils, including a body coil and two pull wire coils, is disclosed. The triple coil system can provide maximal resistance to compression of the catheter's proximal shaft, as well as maximization of the curve angle that the catheter tip can achieve. Additionally, the tri-coil catheter can allow for a lower initial compression load and a more flexible proximal shaft. A gap between the outer diameter of the pull wire and the inner diameter of the pull wire compression coil that is equal to about 10-30% of inner diameter of the pull wire compression coil can provide optimal catheter performance.
    Type: Grant

  • Patent number: 11064929
    Abstract: The instant disclosure relates generally to a tip electrode for delivering irrigant to a distal portion of the tip electrode and irrigated catheter tips incorporating such a tip electrode. The distal portion of the tip electrode can have additional fluid ports on the distal edge of the tip to provide additional fluid flow to that region.
