INTRAVASCULAR INTRODUCER DEVICES
First Claim
1. A device for introducing a catheter into a patient'"'"'s vasculature, the device comprising:
- a housing;
a distal sheath extending distally from the housing and adapted to be inserted into a patient'"'"'s vasculature with the housing positioned outside of the patient'"'"'s vasculature;
a distal hemostatic seal mounted within the housing;
a proximal hemostatic seal mounted within the housing at a location proximal to the distal hemostatic seal;
a tube positioned within the housing and movable longitudinally relative to the distal hemostatic seal between a proximal position and a distal position, wherein in the proximal position a distal end of the tube is positioned proximal to the distal hemostatic seal with the distal hemostatic seal closed, and wherein in the distal position the distal end of the tube extends through the distal hemostatic seal; and
wherein a proximal end of the tube, or an end of another tube of the device, is movable longitudinally relative to the proximal hemostatic seal between a first position within the proximal hemostatic seal and a second position not within the proximal hemostatic seal.

Abstract
Disclosed embodiments of introducer devices provide hemostatic sealing and allow a delivery catheter to be inserted through the introducer seals without the use of a separate loader device that covers a medical device that is mounted on the catheter. Some disclosed introducers comprise a housing, a distal sheath extending distally from the housing and adapted to be inserted into a patient'"'"'s vasculature, a distal hemostatic seal mounted within the housing and a proximal hemostatic seal mounted within the housing, and a slidable tube positioned within the housing that is movable longitudinally relative to the distal hemostatic seal between a proximal position and a distal position, wherein in the proximal position a distal end of the tube is positioned proximal to the distal hemostatic seal with the distal hemostatic seal closed, and wherein in the distal position the distal end of the tube extends through the distal hemostatic seal.

19. A method of introducing a delivery catheter into a patient'"'"'s vasculature, the method comprising:
-
positioning a proximal tube portion of an introducer through a proximal hemostatic seal of the introducer such that the proximal hemostatic seal is open; inserting a distal end portion of a delivery catheter distally through the proximal tube portion and through the open proximal hemostatic seal such that a medical device mounted on the distal end portion of the delivery catheter is positioned between the proximal hemostatic seal and a distal hemostatic seal of the introducer; positioning a distal tube portion of the introducer through the distal hemostatic seal such that the distal hemostatic seal is open; and advancing the delivery catheter distally such that the medical device mounted on the delivery catheter moves distally through the distal tube portion and through the open distal hemostatic seal and into the patient'"'"'s vasculature. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
