Abstract
A method and apparatus are disclosed for an optimized transseptal procedure for providing left heart access, that reduces the number of devices that are used in order to minimize procedural time, complexity and cost. The apparatus comprises a hybrid dilator that comprises the combined functionality of a transseptal sheath and dilator assembly. The hybrid dilator comprises: a dilator shaft defining a lumen for receiving a crossing device therethrough, the dilator shaft being structured to provide support for the crossing device when the crossing device is used to create a puncture in a tissue; and a distal tip having an outer diameter which tapers down to an outer diameter of the crossing device for providing a smooth transition between the crossing device and the distal tip when the crossing device is inserted through the lumen and protrudes beyond the distal tip.
