An apparatus and method for catheter-based sensing and injection at a target site within a patient's body. An injection catheter is equipped with electrodes at its distal end which contact the surface of a target site, such as an AV node of the heart. Electrical signals detected at the target site by the electrodes are fed via leads to the proximal end of the catheter, where they are received by a monitor, such as an EKG monitor. If the electrical signals satisfy predetermined criteria, a needle within the catheter is extended into the target site, and a therapeutic agent is injected into the target site.

Catheter with sensor tip and method of use of same

An apparatus for the injection of therapeutic and other agents at a target site within a patient's body. A catheter including a first elongated shaft having a distal end and a proximal end and a lumen extending therebetween. The catheter also including a second elongated shaft slidingly disposed in the first elongated shaft, the second elongated shaft having a distal end and a proximal and a lumen extending therebetween. The catheter further including a third elongated shaft disposed in and attached to the second elongate shaft, the third elongated shaft to move in a one-to-one relationship with the first elongated shaft and the second elongated shaft to maintain a predetermined needle deployment length as each are subjected to various bend configurations.

Variable depth injection device and method

Catheter with sensor tips, tool and device and methods of use of same

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.

Elongated medical device with functional distal end

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 an elongated configuration, a second member pivotally coupled to the first member at a pivot area of the first member, and a manipulation member extending through either a first lumen or a second lumen of the first member. The second member of this device may have a first region on one side of the pivot area and a second region on a different side of the pivot area. The medical device may also include a third member slidable within one of the lumens of the first member.

A catheter shaft assembly is disclosed. A catheter shaft in accordance with the present invention comprises a first elongate shaft having an inner surface defining a lumen, a second elongate shaft slidingly disposed within the lumen of the first elongate shaft, at least one interstitial member disposed between the inner surface of the first elongate shaft and the outer surface of the second elongate shaft.

Catheter shaft assembly

A therapeutic catheter is provided. This therapeutic catheter may include an outer tube with a distal piercing end and a first lumen which may have a stop positioned within it. The first lumen may also have a plug positioned within it wherein the stop may have an inside diameter smaller than the inside diameter of the first lumen and the plug may be sized to prevent travel of the stop outside of the distal end of the outer tube.

Variable tip catheter

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.
