Abstract: Medical devices and method for making and using medical devices are disclosed. An example method for treating a blood vessel may include disposing a medical device within the blood vessel at a position adjacent to a lesion. The medical device may include an elongate shaft having a distal end region, a balloon coupled to the distal end region, and a cavitation member disposed within the balloon. The method may also include inflating the balloon to a first pressure, activating the cavitation member, and inflating the balloon to a second pressure greater than the first pressure.

Abstract: A system for delivering an implantable medical device includes a handle housing. An outer sheath is coupler secured to a proximal end of an outer sheath that is configured to cover at least a portion of the implantable medical device. An outer sheath drive assembly is operably coupled to the outer sheath coupler and is configured to translate the outer sheath relative to the handle housing. An actuation shaft coupler is secured to a proximal end of an activation shaft. An actuation shaft drive assembly is operably coupled to the actuation shaft coupler and is configured to cause the actuation shaft to translate relative to the handle housing and shift the implantable medical device from a first position and a second position in which the implantable medical device is radially expanded relative to the first position.

Abstract: A delivery system for an implantable medical device includes an outer shaft and an inner shaft translatable within the outer shaft. An internally exposed coil is disposed within the inner shaft and is electrically coupled to an externally exposed coil that can be used to inductively transmit a current flowing through the internally exposed coil. An actuation member extends within the inner shaft and includes a coupler, a force translation rod that extends proximally from the coupler and a plurality of push pull rods that extend distally from the coupler and that releasably couple to the implantable medical device. As the force translation rod moves relative to the internally exposed coil, an impedance varies in accordance with relative position.

Abstract: A drive assembly for use with a delivery catheter for delivering an implantable medical device includes a drive motor configured to be operably coupled to an inner shaft of the delivery catheter such that operation of the drive motor causes the inner shaft to translate relative to the outer shaft and a controller. The controller is configured to receive a position signal from a position sensor indicating a position of the implantable medical device relative to the outer shaft as well as a motor signal indicating a rotational position of an output shaft of the drive motor. The controller is configured to output a control signal instructing operation of the drive motor based upon the indicated rotational position of the output shaft of the drive motor and the indicated position of the implantable medical device relative to the outer shaft.

Abstract: A sensor assembly includes a multilayer circuit, a first magnetic field sensor, and a second magnetic field sensor. The multilayer circuit extends between a proximal end and a distal end along a longitudinal axis. The multilayer circuit includes a plurality of electrical pads positioned at the proximal end. The first magnetic field sensor is coupled to the multilayer circuit and has a primary sensing direction aligned with the longitudinal axis. The second magnetic field sensor is coupled to the multilayer circuit and oriented with respect to the first magnetic field sensor such that the second magnetic field sensor has a primary sensing direction aligned with an axis orthogonal to the longitudinal axis.

Abstract: A tissue modification apparatus includes at least a first plurality of grippers aligned in a plane adapted to secure a first edge of a patch of tissue. The plurality of grippers are each secured to a first force actuator. The first plurality of grippers are each adapted to pivot relative to the first force actuator about an axis perpendicular to the plane. In some cases, a plurality of grippers are attached to a force actuator by a passive force transfer mechanism. In some cases, individual force actuators are attached by pivoted connections to individual grippers. Methods of treating tissue can secure tensioned tissue to a frame to retain the tension during a treatment (e.g., cross-linking the tissue with a chemical cross-linker).

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example delivery system for an implantable medical device includes an inner shaft having a proximal end region, a distal end region, a non-circular lumen extending therethrough. The delivery system also includes a tension resistance member extending at least partially between the proximal end region and the distal end region, a deployment catheter disposed along the outer surface of the shaft, and an actuation shaft disposed within the non-circular lumen. Further, the actuation shaft is coupled to the implantable medical device and translation of the actuation shaft shifts the implantable medical device from a first position to a second position.

Abstract: A sensor assembly includes a first magnetic field sensor that is a first type of sensor and has a first magnetic field sensitivity in a first primary sensing direction. The first primary sensing direction is along a longitudinal axis of the sensor assembly. The sensor assembly further includes a second magnetic field sensor that is a second type of sensor different than the first type of sensor and has a second magnetic field sensitivity in a second primary sensing direction that is less than the first magnetic field sensitivity. The second primary sensing direction is along a second axis that is different than the longitudinal axis.
