Devices, systems, and methods for implanting a patient-specific prosthesis at a treatment site in a patient are disclosed herein. In some embodiments, a patient-specific prosthesis includes a tubular graft and a coupling member. A fenestration can be disposed in the tubular graft, the fenestration corresponding to a predicted branch blood vessel location. The coupling member can be disposed about the fenestration. The coupling member can include a coil configured to expand from a first configuration to a second configuration in response to the application of an expanding force. The coil can be configured to contract to a third configuration upon removal of the expanding force.

Systems, devices, and methods for coupling a prosthetic implant to a fenestrated body

Devices, systems, and methods for coupling a prosthetic implant to a fenestrated body are disclosed herein. In some embodiments, a branch stent graft is provided. The branch stent graft can include an engagement portion for engagement with an opening in a fenestrated body, such as a vessel wall or an aortic stent graft. The engagement portion of the branch stent graft can be coupled to the fenestrated body such that the branch stent graft can move, rotate or shift relative to the fenestrated body but such that axial movement of the branch stent graft is restricted and/or prevented.

Modular pre-loaded implant subassemblies that can be packaged separately from a handle, which allows using any one of a plurality of separately packaged modular pre-loaded implants with a common handle.

Modular pre-loaded medical implants and delivery systems

An interventional catheter assembly comprising a catheter for insertion and guidance to a target site in a body lumen or a cavity and an operating head mounted in proximity to a distal end of the catheter and comprising a system for removing obstructive material from the target site is provided. In certain embodiments, the catheter assembly includes at least one aspiration port located proximal to the operating head that communicates with a first sealed lumen for withdrawing fluids and obstructive material from the target site. The catheter assembly may also include at least one liquid infusion port that communicates with a second sealed lumen for supplying fluid to a location in proximity to the target site. Kits including the interventional catheter assembly with an aspiration and/or infusion conduit are also provided.

Interventional catheters incorporating aspiration and/or infusion systems

A rotatable operating head for removal of obstructive material from a target site in a body lumen or cavity is operably connected to a rotatable, translatable drive shaft that is driven by a drive motor and received through an elongated catheter. The operating head includes a plurality of differential cutting blades, with at least one of the cutting blades being a stepped blade, the stepped blade comprising a raised cutting surface positioned adjacent, or in proximity to, a shoulder region.

Interventional catheters having cutter assemblies and differential cutting surfaces for use in such assemblies

An interventional catheter assembly has an operating head and catheter system that are inserted and navigated within a patient's body while an operator controls the system externally of the operating head. An operating head is positioned at or near a distal end of the catheter system and coupled to a drive shaft and drive system for rotation. A guidewire brake control system interrupt prevents the drive system from being actuated when the guidewire brake is in a released position, and a selectable guidewire brake interrupt override control permits an operator to translate and/or rotate the drive shaft and operating head while the guidewire is simultaneously moved. This allows withdrawal of the guide wire and the operating head from the target site while rotating the operating head.

Interventional catheter assemblies, control systems and operating methods

Sheath assemblies incorporating slotted structures at one or more areas provide areas of different flexibility and bendability characteristics along the length of the sheath assembly. An inner tubular member has an arrangement of discontinuous slots along at least a portion of its length, with at least some of the slots terminating in an enlarged aperture at at least one terminus of the slot, and a flexible outer tubular member contacts and extends over at least a portion of the inner tubular member.

Flexible sheath assemblies and interventional catheter systems incorporating them

A rotatable operating head for removal of obstructive material from a target site in a body lumen or cavity is operably connected to a rotatable, translatable drive shaft, that is driven by a drive motor and received through an elongated catheter. The operating head includes a plurality of differential cutting blades, with at least one of the cutting blades being a stepped blade, the stepped blade comprising a raised cutting surface positioned adjacent, or in proximity to, a shoulder region.

An interventional catheter assembly comprising a catheter for insertion and guidance to a target site in a body lumen or a cavity and an operating head mounted in proximity to a distal end of the catheter and comprising a system for removing obstructive material from the target site is provided. In certain embodiments, the catheter assembly includes at least one aspiration port located proximal to the operating head that communicates with a first sealed lumen for withdrawing fluids and obstructive material from the target site, together with at least one liquid infusion port penetrating the catheter and located proximal to the at least one aspiration port that communicates with a second sealed lumen for supplying fluid to a location in proximity to the target site.
