    摘要： A method and medical system to take electrical readings includes an electrocardiogram (ECG) monitor, an electrode coupled to the monitor via a first lead and a needle such as an injection needle. The needle has a proximal end coupled to the monitor, where the monitor is able to measure an electrical pattern between the electrode and a distal end of the needle. In one example, the medical system is used to detect the contact, penetration, health and perforation of tissue at a target site.

    摘要： A system and method for simply and reliably determining the location and orientation of a medical device within a patient's body. A medical device, such as a catheter, has bending indicators on or imbedded in its wall, and passes through an anatomical reference of known orientation relative to a target site within the patient. Information from the tube bending indicators permits determination of the orientation of a feature, such as an orifice, at the distal end of the medical device relative to the anatomical reference. From the known orientation of the anatomical reference, and information on the location and orientation of the distal end of the medical device obtained from fluoroscopic imaging from a single direction, the physician may reliably determine the orientation of the distal feature relative to the target site, eliminating the need for imaging from multiple directions.

    摘要： The present invention generally relates to a medical device for delivering a therapeutic agent to an internal portion of a patient's body. The medical device includes a shaft and a self-expanding delivery member in operative communication with the shaft. The delivery member is shaped from a porous material that is capable of releasing a therapeutic agent to an internal portion of a patient's body. The medical device further includes a therapeutic agent delivery lumen in fluid communication with the delivery member to fluidly connect the delivery member with a therapeutic agent source. A retention member may also be provided to selectively collapse the delivery member.

    摘要： A direct injection system with a small diameter that can be easily placed at a desired treatment location is provided, where the system comprises an outer guide catheter having a predefined bend at the distal end. For example, the outer guide catheter may be no larger than a 7 Fr catheter. According to the invention, various mechanisms may be used to alter the curvature of the predefined bend in the catheter, allowing an operator to easily place the distal end of an injection catheter at a desired treatment location. Alternatively, the injection catheter itself has a predefined bend at the distal end, wherein the curvature can be adjusted by adjusting the position of the injection catheter within a guide catheter.

    摘要： A modified medical device for delivery of a pharmaceutically active material is described. The present inventors have found that many conventional medical devices contain a metallic or polymeric component that comes into contact with a pharmaceutically active material during use, and that the contact substantially reduce the pharmaceutical effectiveness of the pharmaceutically active material. The invention described herein concerns various modifications to the metallic or polymeric component that are effective to diminish such a substantial reduction in pharmaceutical effectiveness.

    摘要： Devices and methods for performing improved percutaneous myocardial revascularization (PMR) procedures. One device includes a preassembled PMR drug delivery catheter and a drug neutralizing vial. The vial assembly allows prepping the PMR catheter by flushing drug through distal needle, and into a vial cavity where the drug is neutralized by a neutralizing agent. One set of devices includes needles having protrusions secured to the distal regions of drug delivery tubes. One needle has outward protruding barbs engaging the inner tube wall while another needle has outward threads which can screw into the tube inner wall. Radiopaque marker bands are also included in the present invention which are asymmetrically distributed on the catheter shaft, allowing a treating physician to determine under fluoroscopy whether the catheter distal region is pointed away or toward the treating physician, as well as determining whether the catheter distal region is rotated toward or away from the treating physician. PMR devices include catheters having dual injection needles, for both injecting a drug into the heart wall and a radiopaque contrast media to mark the already treated sites. One PMR injection device has multiple stops for allowing controlled, variable needle depth penetration with a single distal needle tip.
