摘要： An obturator as part of a biopsy system enhances use with Magnetic Resonance Imaging (MRI) by indicating location of a side aperture in an encompassing cannula. The cannula (e.g., detached probe, sleeve sized to receive a core biopsy probe) includes a side aperture for taking a tissue sample. When the obturator is inserted in lieu of the biopsy device into the cannula, a notch formed in a shaft of the obturator corresponds to the side aperture. A dugout trough into the notch may further accept aqueous material to further accentuate the side aperture. In addition, a series of dimensionally varied apertures (e.g., wells, slats) that communicate through a lateral surface of the shaft and that are proximal to the side aperture receive an aqueous material to accentuate visibility in an MRI image, even in a skewed MRI slice through the cannula/obturator.

摘要： A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument, and in particular a sleeve, to a biopsy site of suspicious tissues or lesions. A depth stop enhances accurate insertion, and prevents over-insertion or inadvertent retraction of the sleeve. The sleeve receives a probe of the MRI-compatible biopsy instrument and may contain various features to enhance its imagability, to enhance vacuum and pressure assist therethrough, and marker deployment etc.

摘要： A patch and sensor assembly has a biosensor housed in a reusable portion that connects to a mapping and localization system (MLS) via biosensor wires. A disposable portion has an electrode layer through which signals are transmitted to the MLS via ACL wires. The biosensor and ACL wires extend through a single cable exiting the reusable portion. The disposable portion includes an adhesive layer for adhering the electrode layer to a foam layer on the electrode layer, and an engagement element for detachably receiving at least a portion of the housing of the reusable portion. The reusable portion includes a housing in which the biosensor has biosensor wires that exit the reusable portion. The housing is also adapted to carry and/or provide support to an ACL contact member responsive to the electrode layer of the disposable portion, and ACL wires that exit the reusable portion.

摘要： A medical device control handle or catheter includes deflection assembly and at least one of the following: a disk actuator, a lever actuator and a ring actuator for actuating additional puller wires in manipulation of multiple features of the medical device or catheter independently of each other. The disk actuator has a common rotational axis with but is rotationally independent of the deflection assembly. The lever actuator has a separate rotational axis. The ring is mounted outside of the control handle and rotatable relative to the control handle to actuate another puller wire for manipulating another feature of the catheter.Each of the disk, lever and ring actuators are of a design that allows existing control handles and catheters to be readily modified to include these actuators.

摘要： A device that shields internal organs and tissues from medical procedures performed within a patient's body, especially in the chest cavity where ablation and related procedures are performed in or near the heart, includes a catheter body, a distal section, and a barrier member that can be inflated with fluid to act as a barrier to extreme temperatures and physical trauma, and be deflated to a smaller size to facilitate entry and removal from the patient's chest cavity. In a more detailed embodiment, the barrier member is a balloon that can protect the esophagus, which can be provided with folds and shape memory elements so that the balloon expands and collapses into predetermined configurations. Fluid is fed to and drawn from the barrier member via an irrigation tubing that extends along a catheter shaft and is in communication with a lumen of a deflectable tubing section that extends through an interior cavity of the barrier member. The catheter can be adapted for uni- or bi-directional deflection.

Each of the threaded member and the adjustment member has a generally cylindrical configuration. The threaded member has an outer surface configured with a helical guide channel. The adjustment member is configured to guide the guided member to move within the helical guide channel to advance and retract the device. The adjustment member can be rotatable over the threaded member by the user to control advancement and retraction of the device. The device may be a stiffener wire, a needle or any other device suitable for advancement and retraction in a catheter.

摘要： An patch and sensor assembly for use in an EP mapping system has two portions: a reusable portion and a disposable portion. The reusable portion houses the biosensors used in magnetic based location and mapping systems and the electrical lead necessary to communicate between the biosensor and the mapping system. The reusable portion may also contain a portion of the electrode necessary to receive electrical signals from the body of the patient. The disposable portion of the patch and sensor assembly contains an adhesive covered flexible patch having at least a portion of the electrode used to receive electrical signals form the body of the patient and may contain the electrical lead necessary to communicate such an electrical signal to the mapping system. The disposable portion contains a receptacle adapted to receive and mechanically secure the reusable portion to the disposable portion of the assembly. Such a patch and sensor assembly is useful in hybrid magnetic and impedance based location and mapping systems such as those used in electrophysiology.
