Abstract
Therapeutic catheters for increasing myocardial blood perfusion in procedures including percutaneous myocardial revascularization (PMR), which can include tips for cutting into the myocardium to stimulate a healing response and/or for injecting angiogenic substances. PMR catheters can include an outer shaft slidably housing an inner shaft having a distal therapeutic tip. The outer shaft can be slidably disposed in a guide catheter and have an expandable atraumatic distal tip for presenting an enlarged distal profile against the heart chamber wall. The enlarged atraumatic profile can reduce the likelihood of the outer shaft penetrating undesirably into the myocardium. One expandable distal tip expands radially when forced against the endocardium. Another expandable tip expands when unconstrained by the guide catheter. Yet another expandable tip expands when manipulated by an elongate manipulation member.
