A catheter system () for treating a treatment site () within or adjacent to the vessel wall of a blood vessel (), or the heart valve, includes an energy source (), a balloon (), an energy guide (A), and a balloon integrity protection system (). The energy source () generates energy. The balloon () is positionable substantially adjacent to the treatment site (). The balloon () has a balloon wall () that defines a balloon interior (). The balloon () is configured to retain a balloon fluid () within the balloon interior (). The energy guide (A) is configured to receive energy from the energy source () and guide the energy into the balloon interior () so that plasma is formed in the balloon fluid () within the balloon interior (). The balloon integrity protection system () is operatively coupled to the balloon (). The balloon integrity protection system () is configured to inhibit rupture of the balloon () due to the plasma formed in the balloon fluid () within the balloon interior () during use of the catheter system ().

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal member having a proximal end, a distal end, and a proximal diameter. The guide extension catheter may additionally include a collar member attached to an extension portion of the proximal member, where the extension portion may be located at the distal end of the proximal member. The extension portion may allow a delivery device to be inserted through the guide extension catheter to extend along a surface of the extension portion and align with a lumen of a distal sheath of the guide extension catheter.

Guide extension catheter

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal member having a proximal end, a distal end, and a proximal diameter. The guide extension catheter may additionally include a collar member attached to the distal end of the proximal member, the collar member comprising a base portion and one or more ribs connected to the base portion and extending distally away from the base portion. In still some additional embodiments, the guide extension catheter may further include a distal sheath member attached to the collar member, the distal sheath member having a distal diameter larger than the proximal diameter.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal shaft having a first outer diameter. A distal sheath may be attached to the proximal shaft and may have a second outer diameter greater than the first outer diameter. The distal sheath may be designed to extend past a coronary ostium and into a coronary artery so that another medical device can pass therethrough toward the coronary artery. An expandable balloon may be coupled to the distal sheath.

Medical devices, medical device systems, and methods for using the same are disclosed. An example medical device system may include a guide catheter having a proximal end, a distal end, and a lumen extending therebetween. The guide catheter may be designed to guide a therapeutic catheter to a target site. A guidewire may be disposed within the lumen of the guide catheter. The system may also include a trap balloon catheter including a catheter shaft and a balloon coupled to the catheter shaft. The trap balloon catheter may be designed to extend through the lumen of the guide catheter to a position adjacent to the distal end of the guide catheter. A trap balloon retainer may be coupled to the catheter shaft. The trap balloon retainer may be designed to prevent a distal end of the trap balloon catheter from extending distally beyond the distal end of the guide catheter.
