  • Patent number: 9216102
    Abstract: Medical device loading apparatuses, systems, methods and kits are described. A loading apparatus comprises a main body having a proximal end defining a proximal opening, a distal end defining a distal opening, and a passageway extending between the proximal and distal openings. An expandable intraluminal medical device can be loaded into a delivery catheter using the loading apparatus by placing the device into the passageway such that it is in a radially-expanded configuration; pulling the device along an axial path through the loading apparatus such that the device transitions from the radially-expanded configuration to a radially-compressed configuration; and pushing the radially-compressed device along the axial path into the delivery catheter.

  • Publication number: 20150306329
    Abstract: An adapter for use in airway exchange procedure capable of being rapidly coupled and uncoupled to the catheter and being capable of regulating the flow of fluid delivered to the trachea of the patient. Oxygenation is received at the proximal end of the adapter and delivered to a catheter at the distal end. The adapter may include a relief valve to release excess fluid from the provided oxygenation. The adapter may also include a throttling valve to limit the flow of fluid within the valve, preventing excessive pressure or flow rate of breathable fluid to the catheter. During the procedure, the adapter and oxygenation source may be rapidly uncoupled and coupled to the catheter by a connector on the distal end of the adapter.

  • Patent number: 9108032
    Abstract: A valve assembly (10) for controlling a flow of fluid includes a housing (30) having a passageway (33), and a valve sheath (40) disposed interiorly of the housing, at least substantially along the housing passageway. The valve sheath includes a cylindrical valve body (42) having a pair of generally wedge-shaped voids (50A, 52A) formed along opposing longitudinal sides of the valve body. Each of the wedge-shaped voids comprises first and second inwardly-directed sides that converge to define a generally linear edge. The edges are disposed along the valve body in a generally diagonal orientation with respect to a longitudinal axis through the valve body. The respective linear edges are structured and aligned in the valve body to meet along a passageway through the valve body interior in a manner to selectively close the valve body interior passageway, and to yield to permit passage of an interventional device therethrough.

    Abstract: A gastrointestinal suture anchor set device includes a pusher slidably received in a needle. A suture clamp assembly includes an anchor attached to one end of a length of the suture, which is slidably received in a sequence of passages defined by a suture clamp in a high profile sliding configuration. The anchor is received in the distal end of the needle with the suture extending outside of the needle. The clamp includes a series of disks movable to a low profile clamped configuration at which different segments of the suture are clamped between faces of adjacent disks. The series of disks define a sequence of suture passages that are segments of a tortuous pathway through the clamp traversed by the suture.

  • Patent number: 8926687
    Abstract: An endoluminal prosthesis may include a tubular graft extending in a longitudinal direction, where the graft has an inner surface forming a lumen extending a length of the graft. An elongate member may be attached to the graft in a circumferentially and longitudinally extending manner such that the elongate member forms a series of longitudinally spaced apart turns, each turn extending substantially around a circumference of the graft. The elongate member may torsion the graft in at least the circumferential direction and cause the graft to form circumferentially and longitudinally extending folds in the portions of the graft disposed between longitudinally adjacent turns of the elongate member.

  • Publication number: 20140236189
    Abstract: A device is provided for closing a wound, such as a percutaneous access site. The device is inserted into the wound, and a helically shaped pusher is actuated to penetrate a wall of the wound. The pusher extends a suture through the tissue wall. After the suture is extending through the tissue wall, the pusher is retracted out of the tissue, while the suture remains extending through the tissue. The suture may then be used to close the wound.

  • Publication number: 20140200650
    Abstract: A deployment device for repair of a transected body vessel is described herein. Device can have a handle and one or more shafts coupled thereto. A prosthesis being retained by a sheath can be coupled to the delivery device. The sheath can have end portions coupled to one or more shafts. Rotation of a shaft can retract a sheath portion away from either end of the prosthesis for expansion thereof prior to the middle of the prosthesis. Continued rotation of a shaft can completely remove the sheath from the prosthesis, so that the prosthesis is fully expanded and couples the first and second vessel portions of the transected vessel together. Prosthesis may be retained by overlapping a tubular sheath and lacing a threading member therethrough. Prosthesis may be retained by a splittable sheath.

  • Publication number: 20140188138
    Abstract: A medical instrument, such as a surgical device for manipulating and placing a tissue suture and methods of using the same is disclosed. The device comprises a handle, a hollow shaft removably coupled to the handle assembly and a stylet extending within the hollow shaft and longitudinally slideable therein. Preferably, the stylet is not rotationally moveable relative to the shaft. The stylet may be moved between a first position wherein a grasping member formed on the stylet is retracted into a distal end portion of the shaft and a second position wherein the grasping member extends distally beyond the distal end portion of the shaft. Distal movement of an actuation member on the handle correspondingly moves the stylet to the extended position and movement of the actuation member to a proximal position on the handle correspondingly moves the stylet to the retracted position. Lateral movement of the actuation member on the handle does not impart rotational movement of the stylet relative to the shaft.

  • Publication number: 20140188203
    Abstract: A medical device deployment system includes an inner shaft telescopically received within a retractable sheath and a medical device positioned over the inner shaft. A handle assembly includes a proximal handle portion having a handle body having an elongate slot therethrough. A distal end of the handle body is attached to an open proximal end of the retractable sheath. The handle assembly also includes a distal handle portion attached to a proximal end of the inner shaft through a connection portion. In a pre-deployment configuration, the connection portion is positioned through a proximal end of the elongate slot and the retractable sheath restricts radial expansion of the medical device. In a post-deployment configuration, the connection portion is positioned through a distal end of the elongate slot and the retractable sheath is retracted such that the medical device is not restricted from radial expansion by the retractable sheath.
