Abstract
A catheter assembly according to the present invention includes a handle assembly, an introducer sheath, and a distal tip assembly. The distal tip assembly can include first and second retaining sleeves and a slotted tip with a non-traumatic tip guard positioned at the proximal end of the slotted tip. The handle assembly can include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. Each control knob on the handle assembly controls a portion of the components on the distal by of the catheter by allowing for precise manipulation of various delivery shafts. Each delivery shaft extends from the handle assembly to respective positions towards the distal end of the catheter.
