  • Patent number: 11439384
    Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.

  • Patent number: 11317892
    Abstract: Disclosed are embodiments of devices and methods for imaging the inside of a body part, such as a blood vessel. In particular embodiments, a catheter has a chamber within which is a transducer. A wire guide channel extends throughout the length of the catheter. The transducer is rotatable about the wire guide channel and the transducer is driven by a cable or other device that is connected to a motor which is located outside the catheter. In one form, a torque cable connects the transducer to the motor. In other embodiments, a pusher piece having a plurality of lumens is positioned in the catheter. Each of the lumens is sized to receive a cable, wire, and/or flushing fluid. The lumens maintain the orientation and separation of the cables, wires, and/or to flushing fluid.

  • Patent number: 11071521
    Abstract: There are disclosed embodiments of devices and methods for imaging the inside of a body part, particularly a blood vessel. In particular embodiments, a catheter has a tip chamber, within which is an ultrasound transducer mounted on a pivot mechanism, a motor for turning the transducer, and an implement for pivoting the transducer. Examples of such an implement are a linear motor, a shaft or filament, and the pivot mechanism may be biased to return to a base position when the implement is not pivoting the transducer. In other embodiments, a mirror reflecting ultrasound signals from the transducer may be rotated and/or pivoted, using similar mechanisms.

  • Patent number: 10993823
    Abstract: The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula having an outer surface, and at least one coiled member having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula. A portion of a stent is looped around the unsecured end of the coiled member and disposed within spacing between adjacent turns of the coiled member. Rotation of the cannula subsequently causes the portion of the stent to disengage from the coiled member.

  • Patent number: 10932932
    Abstract: A prosthesis delivery device having a cannula with an expandable positioning device disposed at the proximal end thereof is disclosed. A prosthesis is retained on the cannula distal of the expandable device. Expansion of the expandable device retains and centers the delivery device and the prosthesis carried thereon in the vessel and allows repositioning of the prosthesis without contacting the proximal end of the prosthesis with the vessel walls prior to deployment.

  • Patent number: 10695026
    Abstract: Devices and methods for obtaining a real-time, three-dimensional image of a body part, particularly a blood vessel. A catheter has a chamber in its tip. The chamber contains an ultrasound transducer and reflector which generally face each other and rotate about a common axis. The transducer element on the transducer and the reflective face on the reflector are both tilted off-axis. The difference in angular velocity generally creates a phase shift between the transducer and the reflective face. The phase shift allows the transducer and the reflective face to actively scan a three-dimensional volume that is generally bounded interiorly by a hyperboloid and exteriorly by the effective range of the ultrasound beam. The transducer and reflector may rotate at constant speeds or nonconstant speeds as well in the same direction or in opposite directions.
