A steerable guide sheath system adapted for delivery into a patient's vasculature. The pull wire which is used to tension the deflectable portion of the sheath is wrapped or twisted around the axis of the sheath.

Devices and methods for accessing the vasculature of a patient

A system and method for delivering a drug to a target site within a patient's body. The system and method include a steerable guide catheter and a drug delivery catheter. The steerable guide catheter has a first extension tube and a second extension tube that are joined together and form a shoulder. The delivery catheter has a distal docking segment and a proximal docking segment. The guide catheter is inserted into the patient's body, then the delivery catheter is inserted into the guide catheter. The distal docking segment engages the first extension tube, the proximal docking segment engages the second extension tube, and the shoulder limits the distance the delivery catheter can be inserted into the guide catheter. Also, once the delivery catheter is inserted it can be rotated to attach the helical tip to the target site. The guide catheter also includes a steering mechanism as well as a friction mechanism which controls the tension on the steering mechanism. The delivery catheter also includes two luer fittings, each having its own lumen.

Drug delivery catheters that attach to tissue and methods for their use

Methods for easy, atraumatic access to areas of the vasculature that are otherwise difficult to access, using steerable guide catheters constructed with components that are selected to provide optimal navigability, torque transfer, and push ability for a variety of typical percutaneous access routes. The catheter wall thickness in the deflecting segment of the guide catheter is about 1 French (&#x2153; mm) or less, and includes a slotted deflection tube, and this construction allows a very tight turning radius which in turn enables guide catheter access to regions of the vasculature that are otherwise inaccessible.

Steerable guide catheters and methods for their use

Catheter systems and methods for implanting helical or dart-like implants into the myocardium or other body tissue. The catheter system includes a helix for fixing the distal end of the catheter to the myocardium, an implant held by the helix, mechanisms for driving the fixation helix into the myocardium, and mechanisms for driving the implant into the myocardium, removing the fixation helix and leaving the implant behind. The implant may be coated, filled, or made of a drug or drug eluting compound, or drug delivery matrix of any composition.

Implant delivery catheter system and methods for its use

A catheter system suitable for implanting pacemaker leads. A guide catheter is provided with steering capability, and the necessary steering components are modified to permit the catheter to be sliced during withdrawal, so that the proximal forced applied to the pacemaker lead is minimized and the lead is less likely to be dislodged.

Catheter systems and methods for placing bi-ventricular pacing leads

Catheter-based systems are disclosed for geometrically and temporally controlled deliveries of fluid agents to the heart. Each system includes an elongate catheter shaft, a tissue penetration element at the shaft distal end, and a handle at the shaft proximal end for manipulating the penetrating element. The penetrating element and a proximate conductive coil provide bipolar sensing electrodes. One version of the system includes a fluid lumen through the penetrating element and a contrast fluid lumen open at the catheter shaft distal end. In other versions, the penetrating element contains two fluid lumens. These systems facilitate tissue mapping and therapeutic agent delivery protocols in which several agents can be simultaneously delivered at a depth within heart tissue, prevented from intermingling until they reach the tissue. Treatment and contrast agents can be delivered simultaneously or temporally spaced, directed to the same region or to different regions separated by intervening tissue.

Bio-interventional therapeutic treatments for cardiovascular diseases

A method of treatment of congestive heart failure comprises the steps of introducing an aortic occlusion catheter through a patient's peripheral artery, the aortic occlusion catheter having an occluding member movable from a collapsed position to an expanded position; positioning the occluding member in the patient's ascending aorta; moving the occluding member from the collapsed shape to the expanded shape after the positioning step; introducing cardioplegic fluid into the patient's coronary blood vessels to arrest the patient's heart; maintaining circulation of oxygenated blood through the patient's arterial system; and reshaping an outer wall of the patient's heart while the heart is arrested so as to reduce the transverse dimension of the left ventricle. The ascending aorta may be occluded and cardioplegic fluid delivered by means of an occlusion balloon attached to the distal end of an elongated catheter positioned transluminally in the aorta from a femoral, subclavian, or other appropriate peripheral artery.

Minimally-invasive devices and methods for treatment of congestive heart failure

A catheter for injecting a thermally sensitive gelation material to remote sites within a patient's body by maintaining the thermally sensitive gelation material in a liquid state until it is delivered to a target area within the body.
