Loading devices and methods for percutaneous perforation closure systems
A device for folding an implant having a wing into a an overlapped configuration includes a funnel body comprising: a first portion configured to receive and protect the implant when the wing of the implant is in a flat or relaxed state, a second portion proximal to the first portion and configured to engage and fold opposite first and second side portions of the wing of the implant in a predetermined direction when the implant is retracted proximally from the first portion of the funnel body and into the second portion of the funnel body, and an overlap guide configured to direct the path of a first one of the side portions of the wing such that the first and second side portions of the wing are overlapped in a predetermined manner and to prevent respective edges of the first and second side portions of the wing from butting into each other as the first and second side portions of the wing are guided into the overlapping configuration during proximal retraction of the implant relative to the funnel body.
ARTERIAL-VENOUS OCCLUSION APPARATUS
Expandable occlusive plugs and methods of using them are disclosed. The devices generally include a tubular body bearing multiple slits defining leaves, which expand radially outward when the ends of the device are brought toward one another.
Vessel Occluder
A vessel occluder used to occlude blood flow within the vasculature is described. The vessel occluder can include an expandable mesh portion having a flexible membrane that expands within a cavity of the expandable mesh portion. When expanded, the flexible membrane blocks blood passage through the mesh portion.
PFO Device
A medical device for treating a PFO is presented as well as a mechanism for its delivery, repositioning and/or removal. The device includes a wire or cable framework of six shape-memory cables formed into a right side having six loops that support a right side sail and a left side having six loops that support a left side sail. The right side loops and left side loops are connected together via waist members that extend between the right side and left side loops. Each cable is threaded through a through hole of a central post and pass through one of each of four types of connecting collars that establish the basic shape of the PFO device and retain the cables together to form a flexible and resilient PFO device.
Device for closing openings or cavities in blood vessels
The device for closing openings or cavities in blood vessels, e.g. in veins or in the heart, said device comprises a closing body comprising an outer side having a partial region arranged for blood flow therealong at least in a part of said partial region thereof when said closing body is in its state of use for closing said opening or cavity. Furthermore, the device comprises at least one layer (16) of biostable nonwoven fiber material, which at least within a partial surface of said partial region of said outer side of the closing body is at least partially in abutment on the closing body.
Closing device for tissue openings
There are shown and described embodiments of a closure device for closing holes in tissue, for example in the right atrial appendage. The closure device in particular embodiments includes first and second mesh closure members and a tether or stem connecting them. Embodiments of a delivery device for the closure device are also described.
Wound closure device
Biocompatible wound closure devices including an elongate body and a plug member are useful for wound repair.
Occluder and Anastomosis Devices
An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame and a covering material. In some embodiments, the frame includes a single continuously wound wire that defines an apposition portion, a defect-occupying portion, and a sealing portion. In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the GI tract including the small bowel and colon. In some embodiments, a two-part frame construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame.
BIOMEDICAL DEVICE FOR WATERTIGHT SEALING OF AN OPENING
Disclosed is a biomedical device being introduced by a hollow tube having a longitudinal axis in a subject in a minimally invasive surgery procedure for watertight sealing of an opening including at least two assemblies, each assembly including one flap connected to one arm, the arm having an longitudinal axis; the assemblies including a delivery configuration, a deployed configuration, and a sealed configuration and outwards deployment unit for switching from the delivery configuration to the deployed configuration and inwards deployment unit for switching from the deployed configuration to the sealed configuration. Also disclosed is a kit of parts including an outer hollow tube, an inner hollow tube, and a related biomedical device.
Occluder for occluding an atrial appendage and production process therefor
An occlusion device and a production process for it are described. The occlusion device consists of a mesh or braiding of at least one wire or thread wherein the occlusion device has been given a suitable design using a reshaping and/or heat-treatment process, is self-expandable, and is configured for secure anchoring in an atrial appendage of the left or right atrium of a heart. The occlusion device comprises a proximal retention region on a proximal end of the occlusion device a distal retention region and a central region between the proximal retention region and said distal retention region and wherein the occlusion device has a closed distal end without a holder, and wherein the occlusion device is at least partly of essentially spherical form, and hollow.
