Abstract:
A tissue fastening device is provided. The tissue fastening device may include an elongate member having fastener guides extending between a working end and a control end and a firing aperture disposed on the working end, an arcuate needle disposed within the firing aperture of the working end and rotatable between a retracted position and an extended position, the arcuate needle including an antegrade recess configured to engagably receive an end of a fastener during advancement of the arcuate needle, and a drive mechanism operatively coupled to the arcuate needle and configured to, upon actuation, advance the arcuate needle in a forward rotation to engage the end of the fastener to be installed and push the end of the fastener through one of a tissue and a prosthetic material into a helical configuration.
Abstract:
An insertion instrument is configured to eject a pair of anchor bodies across an anatomical gap so as to approximate the gap. The insertion instrument can include a single cannula that retains the pair of anchor bodies in a stacked relationship, or a pair of adjacent cannulas that each retain respective anchor bodies. The insertion instrument can be actuated so as to eject the anchor bodies into respective target anatomical locations.

Abstract:
A suture-based vessel closure device can perform the dilation of an arteriotomy puncture and does not require previous dilation of the arteriotomy puncture by a separate device or by a procedural sheath dilator. The suture- based vessel closure device can place one or more sutures across the vessel access site such that, when the suture ends are tied off after sheath removal, the stitch or stitches provide hemostasis to the access site.
Abstract:
A cartridge (24) containing a fastener. The cartridge has an elongated sheath (180) containing at least one tissue penetrating member (90). The penetrating member at least partially houses a fastener. The fastener has at least two anchors (100) connected together by a non-resilient flexible suture (106) which does not resist deformation under compressible loads. The cartridge further includes a means for deploying the anchors, wherein the means is movable within the sheath.
Abstract:
Described here are devices, systems and methods for closing the left atrial appendage (114). Some of the methods described here utilize one or more guide members having alignment members to aid in positioning of a closure device (200). In general, these methods include advancing a first guide (1300) having a first alignment member (1304) into the left atrial appendage, advancing a second guide (1302), having a second alignment member (1306), into the pericardial space (116), aligning the first and second alignment members, advancing a left atrial appendage closure device into the pericardial space and adjacent to the left atrial appendage, and closing the left atrial appendage with the closure device. In these variations, the closure device typically has an elongate body (202) having a proximal end and a distal end, and a closure element (204) at least partially housed within the elongate body. The closure element comprises a loop defining a continuous aperture therethrough.
Abstract:
A vascular closure delivery system for closing a tissue wall opening is provided. In one embodiment, the vascular closure delivery system comprises a suturing apparatus, a suture delivery unit (100) and a suture knot system (300). The suturing apparatus and suture delivery unit (100) comprises at least one tube (120), at least one leg (110), a tensioning device (115), a pusher (130), a suturing apparatus (140), and an actuator (112, 113, 230). When the leg (110) is in an open position, the tensioning device (115) exerts tension on the leg such that the leg can move with respect to the tensioning device, and the pusher and suturing apparatus are in an delivery configuration for delivery of the suturing apparatus to the internal tissue wall. Further, actuation of the actuator (113) moves the pusher (130) towards the expulsion . end of the tube such that the suturing apparatus engaging end of the pusher engages the suturing apparatus and expels the suturing apparatus from the tube.
Abstract:
Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.
Abstract:
A tissue repair device includes a closed knotless loop of multifilament flexible material, and a fixation member having a structure that defines a cavity that receives at least a part of the closed loop. The tissue repair device may include a flexible member traversing the loop. The loop may include a portion in which ends of the multifilament flexible material are thermally fused together. The multifilament flexible material may be braided or twisted.
Abstract:
The present invention provides an organ fixture (10) composed of an anchoring portion (11) that is formed in a rod shape by bundling a suturing thread, and a fixing portion (12) made of a suturing thread continuous with said suturing thread that forms said anchoring portion (11). By pulling the fixing portion (12) with respect to the anchoring portion (11) with a force larger than a prescribed level, the suturing thread that forms the anchoring portion (11) can be loosened. In addition, the present invention provides a type of organ fixture set having an inserting unit (20), which pierces and is inserted into the body of the patient while a portion of an anchoring portion (11) and a fixing portion (12) of the organ fixture (10) is accommodated in it, and it can be pulled from the body of the patient while the anchoring portion (11) is left within the stomach wall B. In addition, the organ fixture set has a removing unit (30) for removing the organ fixture (10) from the body of the patient.
