An occlusion catheter system includes a proximal hub having an inflation connection port and an inflation pathway. An inflation catheter member is connected to the proximal hub and has an inflation lumen. A stiffener member defines a longitudinal axis. The proximal end of the stiffener member is connected to the proximal hub. The stiffener member extends through a portion of the inflation lumen. An occlusion balloon has a proximal balloon end and a distal balloon end. A distal catheter member is positioned substantially on the longitudinal axis and is connected to the distal end of the stiffener member. An atraumatic tip is positioned on a distal end of the distal catheter member. The atraumatic tip has a substantially circular profile in a relaxed configuration. A pressure sensor is connected to the occlusion catheter system distally relative to the occlusion balloon and is connected to a processor by electrical wiring.

Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.

An inflatable structure for use in biological lumens and methods of making and using the same are disclosed. The structure can have an inflatable balloon encircled by a shell. The shell can have proximal and distal tapered necks, longitudinally-oriented flutes, and apertures at the proximal and distal ends of the shell. The apertures can be recessed in the flutes in the necks. The shell can also have fiber reinforced walls.

A balloon catheter including an elongated catheter main body portion and a balloon provided on the distal portion of the catheter main body portion. The balloon is inflatable to expand radially outward into an inflated state and deflatable to contract radially inward into a deflated state. The catheter main body portion includes a hollow outer tube and a hollow inner tube disposed within the outer tube. The balloon includes a contact portion that contacts the outer surface of the inner tube and a vane portion protruding from the contact portion radially outward when the balloon is in the deflated state. The contact portion of the balloon includes a connecting portion that connects the balloon to the catheter main body portion.

Systems for providing access across a site of obstruction and methods for manufacturing and using such systems. Such systems may include a sleeve having an inflation lumen; a bushing disposed in a distal section of the sleeve; and an everting member coupled to the sleeve with the bushing, the everting member being movable from an inverted position inside the sleeve to an everted position outside the sleeve in response to an increase in pressure in the inflation lumen.

A rapid exchange balloon catheter including: an outer conduit having a lumen and a wall surrounding the lumen, the wall including a lateral opening formed therein; an inner conduit having a proximal end and a distal end; a sealing sleeve for sealing the lateral opening of the outer conduit; a balloon whose proximal margin is attached to the outer surface of the distal end of the outer conduit, and whose distal margin is attached to the outer surface of the portion of the inner conduit that extends beyond the distal end of the outer conduit; a pushing-pulling mechanism disposed in the outer conduit; and a fluid port for the introduction of an expansion fluid and for the removal of the expansion fluid.

A tube coupling component (4;6) serves for use in a tube coupling system and an irrigation system. The tube coupling component (4;6) comprises a male coupling part (12) opposite a respective female coupling part (11), or a first end fitting (33) opposite a respective second end fitting (34), which tube coupling component (4;6) has an interior pipe (13;31) that extends axially inside an exterior pipe (14;32), wherein the interior pipe (13;31) and the exterior pipe (14;32) are concentric.

A method for coating an inner lumen surface of a tube with a coating solution comprises the steps of moving a coating solution through a tube via a withdrawal system and depositing the coating solution onto an inner lumen surface of the tube. The thickness of the coating solution is deposited onto the inner lumen surface of the tube is between 1 μm and 25 μm. The method further comprises applying a pressure to the tube using a pressure source when the coating solution is within the tube to manipulate a surface tension between the coating solution and the inner lumen surface of the tube.

The vascular occlusion balloon catheter has a balloon, a main lumen, and a balloon expanding lumen. The balloon catheter has an air discharge passage. The air discharge passage has a distal end opening located at a position distal from the balloon and a proximal end communicating with an inner portion of the balloon. The distal end opening of the air discharge passage is positioned inside a portion disposed proximally from a distal end of the balloon catheter. The air discharge passage communicates with the main lumen at the distal end opening of the air discharge passage. The area of a cross section of the air discharge passage orthogonal to an axial direction of the balloon catheter is set to 200 μm.sup.2 to 450 μm.sup.2. The length of the air discharge passage is set to 1.0 to 3.0 mm.

A balloon guide catheter including a balloon and a catheter shaft having a central lumen defined axially therethrough, and an inflation lumen. An exterior surface of the catheter shaft has a distal reduced outer diameter recess area defined therein and a proximal reduced outer diameter recess area separated in an axial direction from the distal reduced outer diameter recess area with a discharge port of the inflation lumen disposed therebetween. The balloon is secured to the catheter shaft by adhesive pooled in the distal reduced outer diameter recess area forming a distal bonding interface area; and the proximal reduced outer diameter recess area forming a proximal bonding interface area. Heat shrink tubing is positioned about the balloon at the distal and proximal bonding interface areas.
