摘要： Magnetic resonance image (MRI) guided tissue penetrating catheters and their methods of use. One or more MRI apparatus (e.g., one or more coils) are positioned on or in a catheter device that includes a tissue penetrator that may be used to form a penetration tract from a body lumen in which the catheter is positioned to a target location outside of that body lumen. The MRI apparatus (e.g., coil(s)) is/are used in conjunction with an MRI imaging system to indicate the position and/or rotational orientation of the penetrating catheter within the subject's body.

摘要： Devices and methods for limiting the depth to which a penetrator is advanced into an organ or mass of tissue. The device generally comprises a first member and a second member. The penetrator is attached to and extends from a second member. The first member has a penetrator shroud and a hollow bore extending therethrough. The second member is engageable with the first member such that a distal portion of the penetrator extends through the penetrator shroud. The distance to which the penetrator protrudes out of and beyond the distal end of the penetrator shroud is adjustable in accordance with the desired depth of penetration. The penetrator may then be advanced into the organ or tissue mass until the distal end of the shroud abuts against the organ or tissue mass, thereby stopping further advancement of the penetrator. The penetrator may have one or more lumen(s) for aspirating or infusing substances.

摘要： Methods and systems are disclosed for treating injury to cardiac tissue by delivering a composition which provides structural support to the cardiac tissue. The composition helps to prevent chamber remodeling by providing structural reinforcement of the tissue or structural reinforcement of the tissue combined with biological therapy. The structurally reinforcing composition can thicken the wall of a heart, or act to prevent further thinning and thereby provide resistance against further remodeling. A number of compositions are disclosed, including multi-component substances such as autologous platelet gel, and other substances. The compositions disclosed can contain additives to augment/enhance the desired effects of the injection.

摘要： The current invention discloses an apparatus for creating openings in tissue membranes and methods for using the apparatus. The apparatus comprises a cutting device that can include a cutting element and a resisting element located on the ends of elongate members. The cutting device can be manipulated so that the cutting element and resisting element are on opposite sides of the target tissue membrane. The cutting device is delivered to a tissue membrane using an elongate delivery device that can be routed through a working lumen in an endoscopic probe. The delivery device can also access the tissue membrane via means other than an endoscopic probe. Embodiments of the invention can include a vacuum lumen in the delivery device and a vacuum source for stabilizing the tissue membrane relative to the apparatus or for securing sections of tissue that are removed from the membrane.
