A balloon guide catheter with a catheter shaft having an outer layer made of a reflowable material and a balloon having a bond interface area with a plurality of punctures defined therein secured about the outer layer of the catheter shaft via seepage of the reflowable material of the outer layer into the plurality of punctures forming a radially outward reflow bond between the catheter shaft and the balloon without the use of an adhesive. One or more reflow jackets made of a reflowable material may also be disposed about the bond interface area of the balloon seeping into the plural punctures forming a radially inward reflow bond.

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.

Provided is a treatment method of being able to improve the obstruction of a biological lumen caused by stenosis of the biological lumen and the stagnation of a secretion. The treatment method includes a disposition step of disposing a dilation portion that can be dilated and deflated, and a collection portion, which is capable of removing a secretion S secreted from a biological lumen from a living body, in a stenosed site occurring in the biological lumen; a dilation step of widening the stenosed site after the disposition step by dilating the dilation portion in the stenosed site after the disposition step; and a removal step of removing the secretion from the living body by a removal portion.

A spinal treatment method and device are provided. The treatment method includes a catheter introduction step of inserting a balloon catheter into a treatment site between nerves extending from a spine, while being bifurcated, and a lesion area that compresses the nerves; and a treatment step of dilating a balloon, on which anti-inflammatory agent is disposed, of the balloon catheter at the treatment site, and applying the anti-inflammatory agent to the treatment site.

Various methods for optimizing coating of medical devices, such as balloon catheters are disclosed. One method configures catheter balloon folds based on balloon diameter and volume. Other methods include using a specifically-sized protective sheath, using a vacuum, using pressure, pulling the balloon through a coating solution, using at least one spacer or a wick between at least one fold for metering a therapeutic coating into the folds of the balloon, placing an intermediate layer between the balloon and the therapeutic coating, placing a soluble film having a therapeutic agent around the catheter balloon or inside the folds, and any combination thereof. Balloon catheters and catheter balloons having a specific folding configuration, a specifically-sized protective sheath, an intermediate layer, or a soluble film are also disclosed.

A femoral arterial ECMO cannula is provided with a balloon that has dual flow and which provides arterial body blood flow during femoral ECMO (Extra Corporeal Membrane Oxygenation).

A device for fracturing calcifications in heart valves including a catheter (12, 22, 42) configured for percutaneous delivery to a heart valve, an fracture-producing element (14, 26, 46, 64, 66,82, 124, 152) disposed at a distal portion of the catheter and operative to vibrate and mechanically fracture calcifications when brought into contact with a calcification at a leaflet of the heart valve, and an energy source (34, 47, 79, 98, 152) operative to vibrate the fracture-producing element so that the fracture-producing element fractures the calcification without necessarily removing the calcification from the leaflet. The device may further comprise a valvuloplasty balloon (30), an embolic protection net (56) and a protective sleeve (110, 130).

Systems and methods for preparing and completing surgical and medical procedures. In particular, kits are provided for improving preparation and completion time for a medical or surgical procedure in which the kit includes modularized compartments containing sterilized medical or surgical equipment and wherein the medical or surgical equipment is organized and/or ordered within the kit to generally correspond to the sequence of steps of the medical or surgical procedure. The kit is particularly applicable to recanalization procedures for stroke patients as well as revascularization procedures for acute myocardial infarction patients where a kit enables faster preparation and completion of these procedures.

A minimally invasive endovascular device for treating a blocked or obstructed biological lumen, such as a blood vessel fully or partially obstructed by deposits of biological matters in or non-biological matters. Certain embodiments of the present invention comprise two capture members that are configured to be placed on either side of the obstruction and enclose around the obstruction for removal. Embodiments of the present invention also provide methods for implementing an endovascular device according to aspects of the present invention.

The present invention provides a medical device that may include a catheter body having proximal and distal portions, a fluid injection lumen disposed within elongate body, and a guidewire lumen disposed within the elongate body. A tip portion defining a cavity in fluid communication with the fluid injection lumen may be coupled to the distal end of the guidewire lumen, and an expandable element may be coupled to the distal portion of the catheter body and to the tip portion, such that the expandable element is in fluid communication with the fluid injection lumen. A shaping element may at least partially surround the expandable element, where the shaping element is configurable in a first geometric configuration and a second geometric configuration.
