Flexible Catheter Guide Patents (Class 600/585)
  • Patent number: 11950800
    Abstract: A catheter for scoring or slicing a lesion. The catheter has a first receiver at a distal end of an expandable portion of the catheter shaft. A first carrier at least partially within the first receiver is moveable axially along the catheter shaft to deploy a first cutter along the expandable portion for cutting or scoring the lesion. In an alternative embodiment, the first carrier may be a wire having a loop, and thus forming a first length including the first cutter and a second length including a second cutter. Actuation of the wire thus causes simultaneous, reciprocal movement of the first and second cutters. Related methods are also disclosed.

  • Patent number: 11937839
    Abstract: Devices described herein include an actuated clot retrieval catheter system. The system includes a catheter having a metallic region positioned at the distal tip of the catheter. The metallic region includes at least two abutting metals in a bimetallic coil configuration. The bimetallic coil expands to form a seal with the inner wall of a vessel. In some examples, the bimetallic coil also captures a clot for removal from the vessel. The bimetallic coil is manufactured from metal-based materials having different thermal expansion coefficients. Conductive wires extend along a longitudinal axis of the catheter from an electrical current controller to at least a portion of the metallic region. Electrical current to the metallic region causes the bimetallic coil to transition from a tight configuration to an expanded configuration and remove the clot.

  • Patent number: 11849956
    Abstract: A device for delivering an implant (e.g., an embolic micro-coil) to a vascular disorder of a patient includes a delivery pusher, a moveable element, and first and second elongate members. The delivery pusher defines a lumen between its proximal and distal ends. The moveable element (e.g., a floating tube or a floating coil) defines a passageway therethrough and is disposed within the lumen of the delivery pusher. The first and second elongate members (e.g., core wires) are also disposed within the lumen of the delivery pusher. A portion of each elongate member passes through the passageway of the moveable element. Movement of the first elongate member in a first direction (e.g., retraction of the first elongate member from a locked to an unlocked configuration) causes a time-delayed or lost motion movement of the second elongate member in the same (i.e., first) direction, which releases the implant from the delivery pusher.

  • Patent number: 11844948
    Abstract: Provided is an accurate, fast and long-term stable fused CRAP. The electrode includes a positioning anchor, a silicone catheter, a sensor compartment and a connecting wire. The method monitors physiological information such as blood PPG, blood oxygen saturation, temperature and impedance of blood in the right ventricular cavity, and monitors blood temperature information, which is also a slowly changing metabolic rate, to provide cross-comparison with blood oxygen saturation information, improving monitoring accuracy of blood oxygen saturation. The rapidly changing right ventricular apical impedance information is monitored to improve rapid response ability of CRAP. The LEDs driving current is dynamically adjusted by monitoring the internal temperature of the PPG sensor and the impedance change of the attached biological tissue, which indirectly reflects thickness change of the attached biological tissue, thereby delaying the failure time of the PPG sensor.

The tip is configured to dilate a blood vessel ahead of the distal end portion of the sheath as the catheter and the sheath are advanced together through the blood vessel. The distal end portion of the sheath is configured to fit snugly around the sealing portion. The catheter further includes a balloon and a proximity-sensor target less than about 10 centimeters from the balloon. The proximity sensor is configured to receive a signal from the proximity-sensor target to aid in positioning the balloon without fluoroscopic guidance.

  • Patent number: 11701499
    Abstract: A guidewire introducible into a bodily lumen having an obstruction therein is provided. An introducer needle is advanced through tissue and into the bodily lumen. A guidewire is advanced through the introducer and into the lumen. The guidewire is advanced further through the lumen until an atraumatic distal tip of the guidewire encounters an obstruction the distal tip cannot pass in a straight forward manner. The distal tip is pressed against the obstruction such that a flexible segment proximal of the distal tip forms a loop distal of the distal tip. The guidewire is advanced further through the lumen such that the loop of the flexible segment is pushed past the obstruction and the distal tip is pulled distally past the obstruction. A greater diameter guidewire extension can be coupled to the back end of the guidewire, providing function as a larger diameter guidewire.

  • Patent number: 11701012
    Abstract: A catheter, such as a fractional flow reserve catheter, includes an elongate shaft having a pressure sensing wire extending to the distal portion of the elongate shaft. The wire has a pressure sensor mounted on the distal end for measuring a pressure of a fluid within lumen of vessel. The pressure sensor wire is disposed within a pocket formed adjacent to the pressure sensor thereby minimizing the profile of the catheter. Bending stresses experienced by a pressure sensor mounted to a fractional flow reserve catheter when tracking the catheter through the vasculature creates a distortion of the sensor resulting in an incorrect pressure reading or bend error. In order to isolate the sensor from bending stresses, the sensor is spaced apart from the pressure sensor wire to allow the pressure sensor and the pressure sensor wire to move independently from one another.
