Disclosed is a catheter robot including: a base, at least two catheter translation modules supported by the base, each catheter translation module including: only one set of movable parts so as to translate longitudinally at a time only one flexible elongated medical element, a group of several crossing tracks within which several corresponding flexible elongated medical elements can translate through the catheter translation module, a switch to direct the single set of movable parts in any of the crossing tracks so as to then translate longitudinally the corresponding flexible elongated medical element, the first and second catheter translation modules being longitudinally spaced apart from each other so that: respective groups of crossing tracks of both catheter translation modules are facing each other so that a given flexible elongated medical element which translates within a crossing track of one group also translates within a crossing track of the other group.

A device and method are described for aspirating within a patient during the delivery of a drug-coated treatment device to help remove drug coating dislodged in a patient's blood. The drug treatment device can be a drug-coated balloon, a drug-coated stent, or similar devices. The device can include an occlusion balloon to help contain the dislodged drug coating and aspiration can be applied proximally, distally, or both proximally and distally of the drug coated balloon during a procedure.

Various embodiments of the present disclosure provide a medical device straightener. The medical device straightener can comprise an elongate shaft extending along a shaft longitudinal axis, the elongate shaft including a shaft proximal end and a shaft distal end, wherein a shaft inner wall of the elongate shaft defines a shaft lumen extending therethrough. The medical device straightener can comprise a bleedback valve that includes an outer circumferential surface. The bleedback valve can be disposed at a distal end of the elongate shaft, within the shaft lumen, wherein a portion of the outer circumferential surface is in communication with the shaft inner wall. The bleedback valve can define a radially expandable lumen longitudinally extending through a center of the bleedback valve.

A device for introduction into a body vessel includes a main elongated element, a balloon positioned at the main elongated element distal end, a distal connecting element positioned at the distal end of the balloon to receive a guidewire during use, and a longitudinally movable sheath positioned external to the main elongated element, a position of the sheath distal end with respect to the balloon defining an exposed portion of the balloon that expands when fluid is delivered to the balloon through the inflation lumen.

A balloon guide catheter including a catheter shaft having a main lumen defined therein extending axially therethrough to receive a guidewire therein and an inflation lumen defined axially therein arranged semi-encircling the main lumen. The inflation lumen having an inlet port radially outward from the catheter shaft and an exhaust vent(s) disposed proximate the distal end of the catheter shaft. The exhaust vent(s) being disposed longitudinally through a distal terminating end of the inflation lumen or radially inward in fluid communication with the main lumen. A porous membrane is disposed at the exhaust vent(s) to permit only gas to pass therethrough. Secured about the outer surface proximate the distal end of the catheter shaft and coinciding with the inlet port is a balloon.

An occlusion catheter system includes an inflation catheter member and an occlusion balloon. The proximal and distal balloon ends are connected to the inflation catheter between the proximal and distal catheter ends. A distal pressure sensor is attached to the inflation catheter member between the proximal balloon end and the atraumatic tip. An inflatable spine is connected to the inflation catheter. The proximal spine end is connected to the inflation catheter near the proximal balloon end and the distal spine end is connected to the inflation catheter near the distal balloon end. The occlusion balloon and the inflatable spine are configured to define blood flow channels with the internal surface and the external balloon surface when the occlusion catheter system is at least partially positioned in the vessel and the occlusion balloon and the inflatable spine are in a partially inflated configuration.

Disclosed herein are various balloon catheter embodiments having a reduced profile (or reduced diameter) section along a length of the catheter body and an inflatable body disposed over the reduced profile section. In certain embodiments, the catheter body has at least one inflation/deflation lumen and a distal inflation/deflation opening defined in a proximal lip of the reduced profile section.

A system and method for deployment of one or more stents at a bifurcation uses a balloon catheter with distal and proximal guidewire ports that are guided by first and second guidewires. The first and second guidewires are directed into first and second side branches at the bifurcation. The catheter is guided by a combination of the first and second guidewires after inserting the first guidewire through the distal guidewire port and the second guidewire through the proximal guidewire port. The combination of the proximal guidewire port and the second guidewire halts advancement of the catheter and the stent it carries beyond an ostium of the first side branch. Additional stents can be delivered to a second side branch and a main branch using the first and second guidewires without re-positioning of the guidewires.

A device for introduction into a body vessel includes a main elongated element, a balloon positioned at the main elongated element distal end, a distal connecting element positioned at the distal end of the balloon to receive a guidewire during use, and a longitudinally movable sheath positioned external to the main elongated element, a position of the sheath distal end with respect to the balloon defining an exposed portion of the balloon that expands when fluid is delivered to the balloon through the inflation lumen.
