Abstract: A releasable coupling mechanism for coupling a delivery catheter and a dilator. The delivery catheter comprising a first mating member at the proximal end and the dilator comprising a second mating member at the proximal end. The proximal end of the first mating member comprises a first coupling means for releasably receiving a second coupling means which is positioned at a distal end of the second mating member. The first mating member further comprising a coupling member the coupling member comprising a pair of engagement members positioned on opposing sides of the coupling member and configured to releasably engage the second coupling means. The first mating member further comprising at least one indicia perpendicular from the pair of engagement members. The indicia indicate an orientation of the first mating member such that the second mating member disengages from the coupling member by simultaneously deflecting the pair of engagement members.

Abstract: A releasable coupling mechanism for coupling a delivery catheter and a dilator. The delivery catheter comprising a delivery catheter hub at the proximal end and the dilator comprising a dilator hub at the proximal end. The proximal end of the delivery catheter hub comprises a coupling member for releasably receiving a raised portion which is positioned at a distal end of the dilator hub. The coupling member has a pair of engagement members positioned on opposing sides of the coupling member and configured to releasably engage the raised portion. The delivery catheter hub further comprising at least one indicia on the housing. The indicia indicate an orientation of the delivery catheter hub such that the dilator hub disengages from the coupling member by simultaneously deflecting the pair of engagement members.

Abstract: An apparatus and method are disclosed for providing feedback for a steerable medical device assembly for deflecting a device, the assembly comprising a control handle comprising an actuation mechanism. The assembly additionally comprises a device coupled to the control handle and operable to be deflected upon actuation of the actuation mechanism, and a feedback mechanism for providing an indication of the deflection of the device, wherein the feedback mechanism is associated with the actuation mechanism for deflecting the device.

Abstract: An elongated medical catheter includes a marker band with sidebands. The elongated medical catheter and the marker band have a radiopacity being different from the radiopacity of the sidebands.

Abstract: The elongated introducer assembly is configured to be selectively movable proximate to the biological feature of the patient, and puncture the biological feature of the patient and form a puncture site through the biological feature; and dilate the puncture site; and receive the auxiliary device for facilitation of movement of the auxiliary device toward the puncture site.

Abstract: Apparatus and systems are disclosed that incorporate coupling mechanisms to enable coupling of two mating member such as medical devices such as introducers, sheaths, dilators. More specifically, the disclosure relates to releasable coupling mechanisms, to allow for releasable coupling of two medical devices such as a dilator and a sheath so the devices can be maneuvered and/or manipulated together for example during a part of a medical procedure.
