Abstract: A transseptal system includes a needle, a guidewire, a handle, and a dilator. The handle defines a needle passage to slidably receive the needle, and a guidewire passage to slidably receive the guidewire. The dilator defines a lumen having a distal region and a proximal region. The dilator is coupled to the handle such that the lumen is open to the needle passage and the guidewire passage. The proximal region of the lumen is sized to simultaneously receive the needle body and the guidewire. The distal region is sized to slidably receive one of the needle and the guidewire on an individual basis. A transseptal puncture and access procedure can be performed, including puncturing tissue with the needle followed by immediate advancement of the guidewire into the accessed area, eliminating the need for multiple instrument exchanges during the procedure.

Abstract: A catheter includes a control handle and a catheter shaft coupled to the control handle and extending from the control handle. The catheter shaft has a proximal end coupled to the control handle and a distal end located opposite the proximal end. The catheter also includes a pull wire band coupled to the catheter shaft. At least a portion of the pull wire band is exposed to an environment outside of the catheter shaft. The catheter also includes a pull wire extending from the control handle and through the catheter shaft to the pull wire band.
