Specimen Marking Clip
A specimen marking clip is provided that is adapted to selectively attach to tissue inside of a patient and corresponding tissue that has been excised from the patient for analysis. Sutures may be associated with the clips to help ensure correct in vivo and ex vivo sample orientation. In vivo clips may remain in the patient's body if necessary.
Method for Marking an Entry Position for an Injection Apparatus in Interventional MR Imaging
A method for marking an entry position for an injection apparatus on a surface of a patient positioned inside a patient receiving region of a magnetic resonance device. The method includes providing a virtual entry position, introducing a marking apparatus into the patient receiving region, acquiring time-resolved MR image data from the marking apparatus by the magnetic resonance device, ascertaining a current position of the marking apparatus based on the time-resolved MR image data, iteratively changing the current position of the marking apparatus using the virtual entry position and the current position, and delivering the liquid from the marking apparatus when the current position matches the virtual entry position.
Methods and devices for fallopian tube diagnostics
Methods and devices for performing minimally invasive procedures useful for Fallopian tube diagnostics are disclosed. In at least one embodiment, the proximal os of the Fallopian tube is accessed via an intrauterine approach; an introducer catheter is advanced to cannulate and form a fluid tight seal with the proximal os of the Fallopian tube; a second catheter inside the introducer catheter is provided to track the length of the Fallopian tube and out into the abdominal cavity; a balloon at the end of the second catheter is inflated and the second catheter is retracted until the balloon seals the distal os of the Fallopian tube; irrigation is performed substantially over the length of the Fallopian tube; and the irrigation fluid is recovered for cytology or cell analysis.
METHODS AND DEVICES FOR DELIVERING IMPLANTABLE PROSTHESES
A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaptation of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.
Biopsy device with selectable tissue receiving aperature orientation and site illumination
A biopsy device includes a disposable elongated probe component having a coaxial arrangement of an elongated tubular section and an elongated tissue cutting member, and having a coaxial arrangement of a first driven gear, a second driven gear, and a third driven gear. The first driven gear is configured to rotate the elongated tubular section. The second driven gear is configured to rotate to longitudinally move the elongated tissue cutting member. The third driven gear is configured to rotate or oscillate the elongated tissue cutting member. A driver component has a coaxial arrangement of a first drive gear, a second drive gear, and a third drive gear. The first drive gear is drivably engaged with the first driven gear. The second drive gear is drivably engaged with the second driven gear. The third drive gear is drivably engaged with the third driven gear.
Apparatus for implanting a preloaded localization wire
An apparatus for implanting a localization wire, wherein the apparatus exhibits a ready configuration and a relaxed configuration, includes a handle having a slot and a cannula disposed within the handle and having an insertion tip and a projection configured to selectively enter the slot. The cannula is movable between a ready configuration and a relaxed configuration. A localization wire is disposed within the cannula. An actuator is configured to retract the cannula into the handle.
Marker materials and forms for magnetic marker localization (MML)
A magnetic marker for marking a site in tissue in the body. In one embodiment, the marker comprises a magnetic metallic glass. In another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 9. In yet another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 6. In yet another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 3.
LOCALIZATION DEVICE, DELIVERY DEVICES, SYSTEMS AND METHODS
Devices, systems, and methods used to deploy a localization device into a target lesion are disclosed. The system includes a delivery device configurable in a ready-to-deploy state and a deployed state. When the delivery device is in the ready-to-deploy state, biased engagement members are engaged with proximal detents of a handle of the delivery device. When the delivery device is in the deployed state, the biased engagement members are engaged with distal detents. The delivery device is transitioned from the ready-to-deploy state to the deployed state by distal displacement of a plunger relative to the handle. The localization device is deployed from a cannula of the delivery device into the target lesion when the delivery device transitions from the ready-to-deploy state to the deployed state.
Implant injection device provided with sequentially released pushing means
An implant injection device includes an injection needle, a receiver housing receiving at least a first implant and a second implant, an injection mechanism, including a pushing rod arranged upstream from the implants and configured to push the implants through the injection needle between an initial position and a final position in which the implants are injected, a pushing device for pushing on the pushing rod, configured to exert a force to move the pushing rod from the initial position to the final position, an intermediate stop device holding the pushing rod in an intermediate position and opposing the force exerted by the pushing device when a stroke of the pushing rod reaches a predetermined distance corresponding to a length of injection of the first implant, and an actuator for actuation by a user, configured to release the pushing rod from the intermediate position to the final position.
Reflector markers and systems and methods for identifying and locating them
Markers and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes one or more photosensitive diodes for transforming light pulses striking the marker into electrical energy, one or more antennas, and a switch coupled to the photodiodes and antennas such that the light pulses cause the switch to open and close and modulate radar signals reflected by the marker back to a source of the signals. The antenna(s) may include one or more wire elements extending from a housing, one or more antenna elements printed on a substrate, or one or more chip antennas. Optionally, the marker may include a processor coupled to the photodiodes for identifying signals in the light pulses or one or more coatings or filters to allow selective activation of the marker.
