Catheter exchange systems and methods may use a cutting tool to sever an encrusted catheter. The cutting tool may include a flexible cannula to encompass and move along the encrusted catheter. A sheath may selectively cover the cutting tool. The cutting tool may selectively transition between a first position in which the cutter is within the sheath and a second position in which the cutting tool is extended beyond the sheath to sever a suture of the catheter. A locking stylet may be used to secure the position of the encrusted catheter and remove the encrusted catheter.

Devices used to provide transseptal access are disclosed. The devices may comprise at least one cannula, a needle, and a handle. The cannula and the needle may be configured to be inserted through a dilator while not damaging a lumen wall of the dilator. The handle may be configured to lock the needle in a retracted position. The devices may be configured to telescopically advance the needle through an atrial septum.

Hemostasis valves and hemostasis valve assemblies can be coupled to a proximal end of an introducer sheath to prevent blood loss through the proximal end of the introducer sheath. Some hemostasis valve assemblies may include an elastomeric member with a variable-width channel that is designed to form a liquid-tight seal over elongate members of different diameter or a single elongate member of variable diameter.

Hemostasis valves and related components and methods

A device and method for slitting a first elongated flexible catheter/sheath used with an elongated flexible component. The device includes a handle, an elongated groove and a cutter member. The cutter member has a sharp distally located cutting edge and a top surface from which a finger projects distally. The cutting edge is located under the finger and is arranged to be located within the annular space between the component and the first catheter/sheath when the first catheter/sheath is within the groove. The cutting edge serves to slice the first catheter/sheath longitudinally when the first catheter/sheath is pulled in a proximal direction. The finger protects the component from injury.
