Multi-lumen tamper tube
The present technology relates generally to a method and device for closing percutaneous punctures, and more particularly to a multi-lumen tamper for such a device. A closure device for sealing a percutaneous puncture in a wall of a body passageway is disclosed, the closure device including a plug configured to engage a surface of the puncture; a toggle configured to engage an internal surface of the body passageway; an elongate filament configured to associate the plug with the toggle; a locking member configured to engage the plug; and a tamper comprising at least two lumens, wherein a first lumen of the at least two lumens is configured to deliver a pharmaceutical agent to the plug.
Steering engagement catheter devices, systems, and methods
Steering engagement catheter devices, systems, and methods of using the same for accessing a tissue, including internal and external tissues of a heart, are disclosed. In at least one embodiment, a steering engagement catheter is provided, comprising an elongated tube having a proximal end, a distal end, and a first wall positioned circumferentially along a length of the elongated tube, the elongated tube configured such that a delivery catheter is capable of at least partial insertion into the elongated tube, at least one steering wire having a proximal end and a distal end, the distal end of the at least one steering wire coupled to the first wall of the elongated tube at or near the distal end of the elongated tube, and a controller operably coupled to the at least one steering wire at or near the proximal end of the at least one steering wire.
Devices and methods for treating fistulae and other bodily openings and passageways
Some aspects of the present invention are directed to unique products and methods for treating fistulae and other passageways and openings in the body. In some preferred forms, an inventive construct will include an elongate graft body that incorporates a plurality of sheet or sheet-like segments. The plurality of sheet or sheet-like segments, in some arrangements, will be stacked in a generally longitudinal direction along the length of the plug body, and optionally, the segments will be received over one or more elongate elements. Elongate elements of this sort can take a variety of forms including a suture, wire, filament, or other relatively thin-bodied elongate member, although in some forms, an elongate element will be or include a somewhat heftier structure such as a biodegradable or non-biodegradable three-dimensional body.
Implants and methods for percutaneous perforation closure
A device for sealing an aperture in a tissue includes: a foot including a distal portion configured to be disposed distal to the tissue when the device is implanted in a position to seal the aperture; and a flexible wing positionable against a distal surface of the tissue adjacent the aperture such that the flexible wing is disposed between the distal portion of the foot and the distal surface adjacent the aperture.
DELIVERY AND ASSESSMENT AIDS FOR IMPLANTS
A treatment system includes an insert that is resiliently deflectable. The tip portion of the insert can be configured to be coupled to the trailing portion of an implant. A guide tube having an internal lumen is configured to permit passage of the tip portion and the body portion of the insert through a guide tube. The guide tube can have a length that is less than that of the insert. Treatment systems include a plurality of inserts, each insert differing from in at least one of length, diameter, and curvature. Treating a patient can include sizing a fistula using an insert.
Devices and methods for assisting cardiac function
Devices and methods for assisting cardiac function. In an exemplary embodiment of a device for assisting heart function of the present disclosure, the device includes a first plate and an opposing second plate, each plate having an inner surface, a cardiac processor coupled to at least one of the first plate and the second plate, a bladder having an inner chamber and disposed between the inner surfaces, and a first catheter having a proximal end in communication with the inner chamber of the bladder and a distal end having a first pericardial balloon coupled thereto, wherein a gas and/or a liquid within the inner chamber of the bladder can be injected into the first pericardial balloon upon compression of the first plate relative to the second plate, and wherein the gas and/or the liquid can be removed from the first pericardial balloon upon retraction of the first plate relative to the second plate.
MEDICAL DEVICE AND SYSTEM FOR OCCLUDING A TISSUE OPENING AND METHOD THEREOF
Devices, methods and systems are provided for occluding a left atrial appendage. In one embodiment, a medical device includes a cover portion and a foam anchor portion with a flexible member coupled therebetween. The cover portion is configured to be positioned over an ostium of the left atrial appendage. The foam anchor portion extends between a proximal end and a distal end to define a length and an axis defined along the length of the foam anchor portion. The foam anchor portion defines a curved external surface radially extending relative to the axis such that the curved external surface extends between the proximal and distal ends of the foam anchor portion. The foam anchor portion is configured to self-expand to provide an outward biasing force from the curved external surface such that a circumferential surface area of the curved external surface biases against tissue of the left atrial appendage.
Vascular closure device suture tension mechanism
Systems and methods for sealing an opening in a wall within the body of a patient are disclosed. In one embodiment, the system has an elongated body coupled to a vascular closure device and a resisting member, the elongated body having a high resistance portion and a low resistance portion and being constructed and arranged to interface with a resisting member to apply a conforming force to a vascular closure device. In some exemplary embodiments, the elongated body comprises a large diameter portion positioned in a proximal end region of the elongated body. Methods and other embodiments are disclosed.
Methods and apparatus for fastening and clamping tissue
Methods and apparatus are provided for fastening or clamping tissue to tissue or non-tissue layers and for occluding tubular body structures. Tissue fasteners having separate proximal and distal implants, each with self-expanding, radially extending legs are connected together on opposite sides of tissue and non-tissue layers. The legs of the proximal and distal implants are interdigitated in the absence of such layers.
METHODS AND APPARATUS FOR FASTENING AND CLAMPING TISSUE
Apparatus and methods for occluding hollow body structures, such as blood vessels, and for attaching tissue layers and/or non-tissue layers together by providing implantable elements on opposite sides of the structure or layers and drawing the implants together to occlude the body structure and/or bring the layers together. The implants are deliverable in a low-profile configuration and self-expand to an enlarged configuration. The implantable elements are delivered by transfixing the body structure, then releasing the implants on opposite sides of the body structure and drawing the implants together to effect an occlusion or attachment. The implants are configured to apply oppositely directed forces to opposite surfaces of the tissue layers at alternate, circumferentially spaced locations and may constrain the tissue in a serpentine pattern or in a direct clamping pattern. The implants grip the tissue in a manner that defines a pressure zone about the transfixion aperture that prevents leakage from the aperture.
