An implant delivery system is described. The implant delivery system utilizes an implant, implant wire, delivery sheath, and a torque device. The torque device may include a cutting element to slit the delivery sheath and a clamp device to fix the position of the implant delivery wire.

A method includes: delivering a biodegradable expandable member into a body cavity of a patient; insufflating the biodegradable expandable member in the body cavity to expand the body cavity; sealing the biodegradable expandable member against an inner wall of the body cavity to seal the body cavity internally; and delivering an endoscope into the body cavity.

The invention generally relates to co-axial stent and catheter systems and medical procedures utilizing these systems. The co-axial stent system is characterized by two-coaxial stents, including an outer resorbable stent and an inner metal stent used to effect deployment of the resorbable stent. The stents may use for treatment of unstable plaque and/or thrombus at the carotid bifurcation and particularly those that are not causing any significant stenosis. The stents may also be used for treatment of cerebral aneurysms. The invention further describes related, equipment, uses and kits for the treatment of unstable plaque and/or thrombus and/or aneurysms.

A delivery system and method for percutaneous aortic valve (PAV) replacement and apparatus used therein. A temporary aortic valve including a reversibly expandable occluder surrounds a central catheter mechanism. The temporary valve is positioned within the ascending aorta, just above and downstream from the coronary ostia. The occluder is configured such that, when fully expanded against the aortic wall, gaps are left that promote continuous coronary perfusion during the cardiac cycle. The temporary valve substitutes for the function of the native aortic valve during its replacement. The native aortic valve is next dilated, and then ablated through deployment of low profile, elongated, sequentially delivered stents. The stent(s) displace the native tissues and remain within the aortic annulus to receive and provide a structure for retaining the PAV. The PAV is delivered, positioned and deployed within the stent(s) at the aortic annulus with precision and relative ease.

Systems and methods for selective auto-retroperfusion along with regional mild hypothermia. In at least one embodiment of a system for providing a retroperfusion therapy to a venous vessel of the present disclosure, the system comprises a catheter for controlling blood perfusion pressure, the catheter comprising a body having a proximal open end, a distal end, a lumen extending between the proximal open end and the distal end, and a plurality of orifices disposed thereon, each of the orifices in fluid communication with the lumen, and at least one expandable balloon, each of the at least one expandable balloons coupled with the body, having an interior that is in fluid communication with the lumen, and adapted to move between an expanded configuration and a deflated configuration, and a flow unit for regulating the flow and pressure of a bodily fluid, and a regional hypothermia system operably coupled to the catheter, the regional hypothermia system operable to reduce and/or regulate a temperature of the bodily fluid flowing therethrough.

Disclosed is an umbilical orthesis plug for an infant, child or toddler. The plug comprises a flange and a body, wherein the body is connected to the flange and wherein the body tapers in width from the flange to the end of the plug. Methods for using the plug and kits comprising the plug are also disclosed.

An artery can be occluded by implanting an occlusion implant within a subintimal space within a wall of the artery. As an example, a catheter having a side port just proximal of an inflatable balloon disposed near a distal end of the catheter can be advanced through the artery to a site at which an occlusion is desired. The inflatable balloon can be inflated and a guidewire can be advanced through a lumen of the catheter, out of the side port and into a subintimal space of the artery, with the inflated inflatable balloon guiding the guidewire towards the artery wall. An occlusion implant can be advanced over the guidewire into the subintimal space and the guidewire can be withdrawn, leaving the occlusion implant positioned within the subintimal space.

Vascular access devices, systems, and methods of their use are provided. In one embodiment, a vascular access device includes a catheter, a balloon, and an inflation lumen. The catheter includes an elongate flexible shaft having a proximal end and a distal end with a primary lumen therethrough. The balloon is disposed about the distal end of the catheter. The inflation lumen is in fluid communication with the balloon and extends toward the proximal end of the shaft of the catheter. The balloon is inflatable into a shape having a first open end, a second open end, a sidewall between the first and second open ends, and a passageway therethrough, which, when the balloon is deployed and inflated within a vessel, permits blood flowing in the vessel to flow through the passageway. The balloon further includes a balloon lumen which is coupled at its first end to the primary lumen of the catheter and which extends to an aperture in the sidewall of the balloon, thereby providing a hemostatic connection and luminal access to a wall of the vessel via the primary lumen of the catheter.

The present invention provides a system, a method, devices and a computer implemented with a method for the monitoring and the control of a subject's organ perfusion. The present invention further provides for the use of a system, a method, devices and a computer implemented with a method for the monitoring and the control of a subject's organ perfusion.

A device and method for establishing retrograde blood flow during recanalization of a vessel having a targeted blockage. While in a collapsed state an occluding component is introduced distally intravascularly traversing the targeted blockage to its distal side. Then, the occluding component transitions to an expanded state having an enlarged diameter forming a seal with an internal wall of the vessel prohibiting anterograde blood flow beyond the expanded occluding component. Retrograde blood flow is thereby established in a region of the vessel bound at one end by the occluding component and at an opposite end by the targeted blockage by dispensing a flushing fluid into the region of the vessel.
