Abstract:
A stylet locking mechanism for preventing axial movement of a stylet relative to a needle of a medical delivery device is disclosed. The locking mechanism comprises first and second ends that may be removably attached to the device, and a hinge for allowing the locking mechanism to be disengaged from a locking position without being completely disconnected from the delivery device.
Abstract:
Medical devices for attaching suture to tissue and that provides reliable and complete closure of perforations and increases the versatility of the device for various other procedures. Embodiments of the medicals devices include a tissue anchor (20) having a crossbar (24) with opposing ends (26,28) and structure (30) for slidably receiving a suture (22).
Abstract:
Medical devices and methods for deploying tissue anchors for simple and reliable closure of openings in tissue are disclosed. The medical device generally includes an access sheath (22) and a flexible puncturing device (24). The flexible puncturing device is sized to be slidably received by the access sheath. The flexible puncturing device has a lumen sized to receive the tissue fastener (10). The flexible puncturing device is operable between a first linear configuration and a second non-linear configuration (Fig. 1). A distal end of the flexible puncturing device is laterally spaced from the access sheath in the second non-linear configuration, and preferably retroflexes to provide placement of the tissue anchors on a proximal side of the tissue.
Abstract:
Medical devices and related methods for closing a perforation in a bodily wall The medical device generally includes a suture having opposing first and second ends and a set of visceral staples. Each visceral staple includes a base and two tines connected to the base, the tines spaced apart two define a slot therebetween. The slot slidably receives the suture therein. Each visceral staple is attached to the bodily wall adjacent the periphery of the perforation. The ends of the suture are tensioned to reduce the distance between the visceral staples and compress the bodily wall around the perforation. The ends of the suture are secured to maintain the compression of the bodily wall and close the perforation.

Abstract:
A delivery apparatus cooperable with a grasping slot of an elevator of endoscope for enhanced delivery to a target location in a patient is disclosed. The apparatus comprises a catheter including an inner lumen and an outer surface. The outer surface has a projection formed thereon. The projection radially extends from the outer surface. The projection is configured to receive the elevator for enhanced delivery in the patient.
Abstract:
An endoscopic cutting device is disclosed. The device comprises an inner catheter including an inner wall having an opening formed therethrough. The inner wall further has a cutting blade moveably disposed thereon and biasingly extends through the opening. The inner wall has a receiving member disposed thereon and is configured to cooperatively receive the cutting blade. The device further comprises an outer catheter including an outer wall moveably disposed about the inner catheter. The outer wall has an aperture formed therethrough. The aperture is configured to moveably align with the opening of the inner wall for allowing the cutting blade to biasingly extend through the opening and biasingly engage the cutting blade with the receiving member to cut.
Abstract:
A biopsy forceps and method of using the biopsy forceps . The biopsy forceps includes a plurality of grasping members (26) extending from an inner shaft (16) . The plurality of grasping members are biased toward an open configuration. Sliding a sheath (18) over the grasping members (26) constrains the grasping members to a closed configuration. A method of performing a tissue biopsy is also disclosed.
Abstract:
The present embodiments provide clip devices, along with systems and methods for delivering and deploying the clip devices. An exemplary clip device (20) comprises inner (30) and outer (50) segments, and further has a delivery configuration, a tissue receiving configuration and a deployed configuration. A distal region (60) of the outer segment is movable with respect to a distal region (40) of the inner segment, thereby creating a spacing between the inner and outer segments for surrounding tissue in the tissue receiving configuration. The inner and outer segments may be biased to return to the deployed configuration, and may comprise generally identical shapes in the deployed configuration wherein the outer segment is proportionally larger than the inner segment. In one embodiment, the inner and outer segments each comprise "V" shapes in the unbiased state. Various delivery systems and methods are provided for delivering and deploying the clip devices disclosed.
Abstract:
Medical systems, devices and methods are provided for accessing a bodily opening that, among other things, are safe and reliable, and facilitate manipulation of a medical instrument. The medical access device generally includes an elongated flexible sheath and an expandable frame connected to the distal end of the flexible sheath. The sheath and expandable frame are operable between expanded and collapsed configurations to provide a pathway from a natural orifice to the bodily opening.
