Methods and devices for performing transjugular carotid flow reversal are provided. A flow reversal sheath is advanced through a transjugular carotid fistula. An occlusion balloon is inflated, causing carotid inflow to be diverted through the sheath and through a flow reversal region positioned in the jugular vein. After reversal of blood flow, a carotid intervention is performed.

A method of inflating a catheter balloon may include providing a balloon assembly operable to provide a balloon diameter vs. balloon pressure profile generally depicting a balloon inflation sequence providing at least one intermediate inflated diameter and a final inflated diameter of a balloon such that the balloon attains the at least one intermediate diameter at a predetermined pressure, and attains the final diameter at a final predetermined pressure that is lower than a predetermined pressure of a last intermediate pressure.

Devices and methods for delivering substances to lung tissue through an extra-anatomic passage created in an airway.

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.

A user-operable controlled furling balloon assembly including a furlable balloon sheath, an elongate furling driving element which is retractable and rotatable about an elongate axis thereof relative to a base element for furling the furlable balloon sheath about the elongate axis, the furlable balloon sheath surrounding the elongate furling driving element and coupled at a first end thereof to the elongate furling driving element and at a second end thereof to the base element and a furling/retraction controlling assembly coupled to the elongate furling driving element and to the base element for limiting an extent of retraction of the elongate furling driving element to be a function of an extent of furling of the balloon sheath, thereby limiting a maximum outer diameter of the balloon sheath when furled and preventing stacking of the balloon sheath.

A balloon catheter includes an elongated main body extending in an axial direction and a balloon connected to the elongated main body. The balloon is inflatable and deflatable in the radial direction. The outer surface of the balloon includes a plurality of recesses that are spaced apart from one another. The balloon catheter also includes a plurality of elongate bodies on the outer surface of the balloon. The elongate bodies are crystals of a water-insoluble drug extending in the radial direction of the balloon away from the interior of the balloon. The elongate bodies each possess an independent long axis. At least two elongate bodies of the elongate bodies are positioned in one of the recesses in the outer surface of the balloon. These two elongate bodies extend from within the recess to a surrounding environment in the radial direction of the balloon.

A balloon catheter that includes an elongated main body extending in an axial direction and a balloon connected to the distal portion of the elongated main body. The balloon includes an interior and is inflatable and deflatable. The balloon catheter also includes a plurality of elongate bodies extending radially away from the outer surface of the balloon. The elongate bodies are crystals of a water-insoluble drug. The elongate bodies each possess an independent longitudinal axis. Each of the elongate bodies includes a base portion at the proximal end of the elongate body. A plurality of elongate body proximal portions extend radially inwardly from the base portion of each of the elongate bodies toward the interior of the balloon. The elongate body proximal portions are continuous extensions of the crystal of the water-insoluble drug.

A balloon catheter, in particular for delivering medicaments, stents or medicament-coated stents in the region of a stenosis, comprising an outer shaft (4) an inner shaft (6), and a balloon (7) at the distal catheter end, which balloon is dilatable by a feedable pressure fluid and which is attached with its proximal end (8) to the outer shaft (4) and with its distal end (9) to the inner shaft (6) which protrudes the outer shaft (4) in the distal direction, and a cover sheath (15) which is seated in a covering position over the contracted balloon (7) and is displaceably guided on the outer shaft (4) and which is displaceable on the outer shaft (4) in the proximal direction via its front opening (17) by the dilating balloon (7) while continuously releasing the same from distal to proximal.

A wound drainage and hemostasis promoting medical device (1) are disclosed. A balloon (15) is temporary inflated and arranged outside a sheath (10), in contact with tissue surrounding a wound cavity for hemostasis promotion. The drainage device comprises a fluid communication channel for wound exudate from wound. The balloon is deflated and retracted into said sheath for removal from said wound cavity. Thus the medical device is percutaneously retractable from said confined wound.

Devices, systems, and methods for auto-retroperfusion of the cerebral venous system. In an exemplary embodiment of a catheter for controlling blood perfusion pressure of the present disclosure, the catheter comprises 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, 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 at least one sensor coupled with the distal end of the body, each of the at least one sensors adapted to gather data relating to a fluid flowing through the lumen, wherein the catheter is configured to be coupled to a flow unit for regulating the flow and pressure of a fluid.
