    摘要： An elongate medical device that may be used for performing medical procedures on a patient is provided. This elongate medical device may include a first member having a distal end, an outer surface, and a first lumen, where the first member may have an elongated configuration such that the length of the first member is at least ten times greater than the width of the first member. The elongate medical device may also have a second member positioned within the first member and a hood stop. The hood stop in this device may be positioned within the first member and may have a distal region and a shoulder region where the shoulder region may be configured to limit the travel of the first member or the second member past the hood stop.

    摘要： 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.

    摘要： A catheter device includes an elongate tubular housing, a cannula, and a flexible proboscis. The cannula defines a cannula lumen which is in fluid communication with a cannula exit port located adjacent the distal end of the elongate housing. The distal tip of the cannula is disposed within the cannula lumen. The cannula defines a proboscis lumen and the cannula has a proboscis exit port in fluid communication with the proboscis lumen. The proboscis exit port is located at the distal tip of the cannula. The flexible proboscis has a distal tip and is disposed within the proboscis lumen.

    摘要： A catheter is provided for the injection of therapeutic agents at a target site within a patient's body. The catheter includes a first elongated shaft having a distal end and a proximal end and a lumen extending therebetween. The catheter also includes a second elongated shaft in the form of a needle slidingly disposed in the first elongated shaft, the needle having a distal end and a proximal and a lumen extending therebetween. The catheter may include a flexible sleeve, wherein the flexible sleeve compresses along the inside of a curve and elongates along the outside of a curve. The catheter may additionally or alternatively include an adjustable distal tissue contact surface, wherein the position of the distal tissue contact surface may be adjusted with respect to a stop surface for stopping the advancement of a needle. The catheter may additionally or alternatively include a fluid pressure contact monitor.
