  • Publication number: 20200146825
    Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. The implant is secured to tissue with anchors that can rotate without axial advancement to engage tissue while drawing the implant closer to the tissue. Collars are used to decrease the angle between struts of a frame to contract the implant. The implants can include a rotatable shaft, such as a threaded shaft, located internally to an axially translatable collar. Rotation of the shaft transmits force to the collar to cause the collar to translate axially, closing the angle of adjacent struts and decreasing the width of the implant and thus of the annulus. The implants can be delivered, secured and contracted via a catheter. The implants are repositionable and retrievable via catheter.

  • Patent number: 8540694
    Abstract: Systems and methods for delivering drugs or other substances to target locations outside of blood vessel lumens or other body lumens. In some embodiments, a catheter having a penetrator is advanced into the body lumen and the penetrator is then advanced from the catheter toward a target location outside of that body lumen. The substance is then delivered through a the penetrator itself or through a delivery catheter that has been advanced through the penetrator to the target location. In other embodiments, the blood vessel or other body lumen is blocked at spaced-apart first and second locations and a quantity of the substance is introduced into the closed-off body lumen between the blocked first and second locations. The substance then diffuses into or through the wall of the vessel or body conduit to reach the target location.

  • Patent number: 8414645
    Abstract: Delivery devices and methods for percutaneously delivering a prosthetic valve to the heart of a patient. These prosthetic valves may be configured to provide complimentary features that promote optimal placement of the prosthetic valve in a native heart valve, such as the aortic valve, mitral valve, pulmonic valve, and/or tricuspid valve. The delivery device includes a release sheath assembly housed within an outer delivery sheath. A release sheath component of the assembly captures a portion of the prosthetic valve to the delivery device, and effectuates complete release of the prosthetic valve with retraction of the outer sheath.

  • Patent number: 7966057
    Abstract: Electro-anatomically navigated catheters (e.g., mapping catheters, tissue penetrating catheters, delivery catheters and/or sheaths) and associated methods whereby devices or substances may be delivered to specific locations within a patient's body and/or penetration tracts or passageways are formed at specific locations between anatomical structures. The catheters are equipped with sensors and a sensing field is created around the body of the patient. The sensor-equipped catheters are then inserted into the patient's body and the position of the catheter-mounted sensor(s) is/are observed on a display representing the sensing field. Apparatus may be included for propelling the catheter(s) to specific locations and/or specific rotation orientations, within the patient's body.

  • Publication number: 20100324471
    Abstract: A transvascular system for delivering a drug to a tissue region from a blood vessel includes a catheter having a distal portion with puncturing, orientation, drug delivery, and imaging elements. The puncturing element is deployable for penetrating the vessel wall to access the tissue region. The orientation element has a predetermined relationship with the puncturing element, the imaging element detecting the location of the orientation element with respect to the tissue region to orient the puncturing element. The catheter is percutaneously introduced into the vessel, the puncturing element is oriented towards the tissue region, the puncturing element is deployed to access the tissue region, and the drug is delivered to the tissue region. An ablation device may also be deployed to create a cavity or fluid reservoir in the tissue region for receiving the drug therein, or an indwelling catheter may be advanced into and left in the tissue region.
