  • Publication number: 20210060308
    Abstract: Devices, assemblies, systems, and techniques described herein may facilitate the delivery of medical fluid, such as an adhesive, to a patient. For example, a medical assembly may include a flexible catheter configured to be disposed within an anatomical structure of a patient, wherein the flexible catheter defines a lumen configured to contain a volume of medical adhesive. The medical assembly may also include a shaft defining a shaft cross-sectional dimension smaller than a lumen cross-sectional dimension of the lumen, wherein advancement of the shaft through at least a portion of the lumen forces at least a portion of the volume of medical adhesive out of the distal opening of the lumen of the flexible catheter.

  • Patent number: 10646325
    Abstract: A method of anchoring a prosthesis includes deploying the prosthesis in a vessel. A delivery system including an anchor constrained within a delivery sheath is advanced to the prosthesis. The prosthesis and a vessel wall of the vessel are penetrated with a leading tip of an exterior tine of the anchor, wherein the exterior tine unfolds upon passing through the prosthesis and the vessel wall. An interior tine is deployed within the prosthesis and vessel wall. In the final deployed state, the exterior tine is exterior to and adjacent the vessel wall, the interior tine is interior to and adjacent the prosthesis, and a tine connector of the anchor extends through the vessel wall and the prosthesis.

  • Patent number: 10542996
    Abstract: In some examples, a vessel closure system includes a catheter configured to be introduced into a vessel of a patient, the catheter defining a catheter lumen, and a closure device configured to be received within the catheter lumen. In some instances, the closure device may include an elongated flexible member and one or more anchors attached to the elongated flexible member. The anchors may be distributed along a length of the elongated flexible member, and each anchor may include an anchor head configured to be introduced into a wall of the vessel and engage with the wall of the vessel to cause the wall to move radially inward in response to a proximal pulling force applied to the elongated flexible member.

  • Patent number: 9220558
    Abstract: A catheter includes a flexible shaft having a length sufficient to access a patient's renal artery relative to a percutaneous access location. The catheter includes a multiplicity of elongated resilient members each comprising a pre-formed curve and extendable beyond the catheter. The resilient members are constrained to a low profile when encompassed by a removable sheath, and expand outwardly to assume a pre-defined shape when removed from the sheath. An electrode assembly is provided at a distal end of each resilient member, and includes an electrode element coupled to an electrical conductor and a thermal sensor in thermal communication with the electrode element. The resilient members have a stiffness sufficient to maintain contact between the electrode elements and an inner wall of the renal artery including irregularities of the inner wall of the renal artery during ablation of perivascular renal nerve tissue.

  • Publication number: 20060224115
    Abstract: A catheter comprises an outer shaft and an inner shaft defining a balloon inflation lumen for transport of an inflation fluid therethrough. The expandable balloon has a proximal waist portion and a distal waist portion with a body portion there between. The balloon is engaged to a distal region of the outer shaft and defines an exterior and an interior where the interior is in fluid communication with the balloon inflation lumen. The inner shaft has an inner shaft wall defining a guidewire lumen for passage of a guidewire. A distal portion of the inner shaft is expandable from an unexpanded state to an expanded state such that in the expanded state the guidewire lumen has a greater cross-sectional area than in the unexpanded state.

  • Publication number: 20060025840
    Abstract: Devices and methods for cooling a target tissue region inside the body are disclosed. A catheter for cooling blood includes an elongated member with a lumen extending longitudinally through a portion of the member. The lumen has an entry port and an exit port through which blood from a body vessel may enter and exit the lumen. An inflatable balloon is positioned between the entry and exit ports of the lumen, which when inflated, occludes the body vessel and prevent normal blood flow. A cooling element cools blood as it flows through the lumen. The cooling element may include a chamber that cools the blood by using a Joule-Thompson orifice to create a phase change of liquid to a gas. The cooling element may also include a thermoelectric cooler.
