An apparatus and method for determining angular position of a sensor within a catheter. The invention is particularly useful for imaging devices delivered to a body lumen by a catheter, as may be the case for IVUS imaging catheters. The apparatus consists of a catheter having an inner core with an imaging sensor disposed within an inner diameter of a sheath of the catheter. The sheath is also provided with an outer diameter which has a center which it does not share with a center of the inner diameter. As a result, the catheter has a wall of non-uniform thickness. The imaging sensor is able to determine its position within its imaging rotation due to the non-uniform thickness. This positioning characteristic helps eliminate any Non-Uniform Rotational Distortion (NURD), which would otherwise result in undesired and unpredictable compressed and expanded images of vasculature sought to be imaged. A method is provided whereby the non-uniform thickness of the wall can be used to locate sensor position angularly within 0. 1 degree of accuracy.

A catheter device having an elongated tubular member with a proximal end and a distal end, and a needle disposed near the distal end. In one embodiment, the needle has a rigid, penetrating tip coupled to a flexible portion by an overlapping joint. The flexible portion enables the needle to bend to a penetrating angle relative to the distal end of the elongated tubular member and penetrate a body tissue without kinking.

Systems, methods and apparatus for acquiring an image from within a body lumen are provided. Systems embodying features of the invention include an intracorporeal imaging component for acquiring imaging information, an image information recording component, and an image information playback component. Methods for acquiring image information from within a body lumen include steps of acquiring imaging information, storing image information, and playing back imaging information. Imaging information may be played back as acquired, or non-sequentially, or composite images may be formed by combining, filtering, enhancing, or subtracting images and the composite images displayed. Devices embodying features of the invention include optical imaging components such as an optical IGW, an optical imaging recording component, and an optical image playback component. The systems, methods and devices are suitable for use with angiopoplasty, stent delivery, and other intracorporeal clinical procedures.

A guide catheter and a needle catheter are disclosed. The guide catheter construction provides for maximum articulation of the deflectable tip and maximum torque response during rotation. The needle catheter may include a release mechanism that imparts a sudden force to the needle in order to facilitate tissue penetration.

Optical windows for intracorporeal devices, intracorporeal devices comprising a window and a method for forming a window for an intracorporeal device are provided. The method comprises placing within a mold an assembly comprising a mandrel located within a pair of parts separated by a collar of window material, heating the window preform effective to cause the window material to soften, and applying force to urge together the pair of parts to deform the window material so as to form a window. The intracorporeal devices, such as imaging devices, include guidewires, catheters, endoscopes. In addition, the method is suitable for joining plastic parts to other parts, such as metal and ceramic parts.

The invention is generally directed to an accessing system for a patient's coronary sinus which includes a tubular support member with a distal extremity extending into the right atrium of the patient's heart. A guide member is disposed within a first lumen of the tubular support member and advanced out an angled distal tip, through the patient's coronary sinus ostium and into the coronary sinus. A stabilizing member, similar to a conventional intravascular guidewire, is disposed within a second lumen of the tubular support member and extends into the right ventricle of the patient and is seated in the apex thereof. To advance the guide member into the CS ostium, the position of the distal extremity of the tubular support member is adjusted within the atrial chamber by moving longitudinally along or rotating about (or both) the stabilizing member and the guide member is advanced into the CS ostium. These steps may be repeated in a predetermined pattern in order to pass into the coronary sinus ostium.
