摘要： Infusion balloon catheter with fortified proximal infusion outlet port, and manufacturing thereof. Infusion balloon catheter includes: inflatable balloon member; shaft having distal end attached to balloon member, and shaft wall enclosing: first lumen providing passage to balloon inflation fluid, and second lumen providing passage to infusion fluid and guidewire; and bending-resistant insert member housed in second lumen and located proximally to balloon member, insert member is affixed to, and conforms to shape of, shaft inner wall surface, and includes one or more openings(s). Shaft wall has infusion outlet port located along, and providing opening to, second lumen proximally to balloon member. Insert opening(s) is/are in direct fluid communication with infusion outlet port whose cross-sectional area is larger than that of infusion inlet opening. Bending-resistant insert member provides fortifying structural support to shaft wall portion surrounding infusion outlet port. Applicable to medical procedures involving injection of imaging contrast material or/and drugs.

摘要： A balloon catheter includes a first balloon positioned inside of a second balloon, both of which are mounted about a catheter and fluidly connected to respective inflation lumens. In a first inflated configuration, the second balloon is inflated and has a shape that includes a plurality of bulb segments, with each two consecutive bulb segments being separated by a waist hoop. In a second inflated configuration both the inner and outer balloons are inflated, and the inner balloon bears radially outwardly against the waist hoop of the outer balloon such that the waist hoop of the outer balloon has a larger diameter in the second inflated configuration than in the first inflated configuration. The bulb segment separated by waist hoops enable the balloon catheter to conform to curved passageways, such as during the implementation of a stent.

摘要： One embodiment provides a balloon catheter which has an inner tube having a main lumen and an outer tube which forms an expansion lumen. A part of the inner tube is connected to the outer tube at a position closer to the proximal end than a balloon, a side hole is open at the connection section, and a weak section is provided to the inner tube a position closer to the distal end than the side hole. The weak section has lower rigidity than the remaining portion of the inner tube. When the balloon is expanded by fluid supplied to the expansion lumen, the weak section is pressed by the fluid pressure to thereby close the main lumen of the inner tube.

摘要： A dilation apparatus includes a shaft, a dilation balloon, and a standoff member. The shaft includes a first lumen and a second lumen. The distal end of the second lumen is proximal to the distal end of the first lumen. The dilation balloon encompasses the second distal end of the second lumen such that the dilation balloon defines an interior in fluid communication with the second lumen. A distal portion of the standoff member is positioned within the interior of the dilation balloon. The distal portion of the standoff member is distal to the second distal end of the second lumen. The standoff member provides a pathway for fluid communication between the interior of the dilation balloon and the second lumen. The standoff member may include a tube, a thread, polymeric beading, or other structures.

摘要： A transseptal cannula having a flexible cannula body, a left atrial anchor coupled to the distal end of the flexible cannula body, and a right atrial anchor operable to be attached to the left atrial anchor in vivo. The left and right atrial anchors are implanted and deployed separately. Delivery of the transseptal cannula to a heart tissue can include a low profile coaxial balloon catheter comprising a tube body including an inner member and an outer member surrounding the inner member and thereby creating an inflation channel between the inner and outer members, a hub coupled to the proximal portion of the tube body and including a fluid space in fluid communication with the inflation channel; and a balloon coupled to the distal portion of the tube body, wherein the balloon is in fluid communication with the inflation channel. The hub of the coaxial balloon catheter is constructed with a low profile so that other surgical devices can be directed over the coaxial hub without deflating and removing the balloon.
