The controllable deployment system for a radially expandable frame utilized during catheterization includes a guide wire with a stop, a radially expandable frame through which the guide wire freely passes, an elongated actuation sleeve over the guide wire, and a friction locking mechanism located at the proximal end of the system. The expandable frame has a closed, radially compact form and an open, radially expanded form. The proximal end of the frame is coupled to an actuator sleeve. The actuator sleeve, at its proximal end, includes a friction locking mechanism having locking members with respective locking surfaces. The locking mechanism permits the user to lock or hold static the actuator sleeve (and therefore, the expandable frame) with respect to the guide wire, typically in an open, radially expanded form and a closed form. Tactile markers or indicia may be included.

The suture lock or suture lock rivet for locking suture thread includes a lock head defining a cut-out, a first locking surface and a stem connected via a breakaway section. The lock also includes a lock base defining a second complementary locking surface. The locking surfaces trap the suture in the cut-out. The stem breaks away. A suture lock applicator is utilized to deliver and apply the suture lock to the surgical site. The system includes the lock loaded within the suture lock applicator. The applicator, or rivet gun, is designed to grip the stem body and coact with the lock base to cause the lock base to slide over the stem towards the lock head or rivet head, and subsequently, with the application of additional longitudinally directed force, to remove the stem from the lock head or first body part at the breakaway section.

The suture clip includes a pair of plates joined together at one end to form a vertex having an acute angle. Each plate, at its remote terminal end, defines an inwardly facing hook. The hook end members establish a clip mouth slightly larger than the diameter of the suture thread such that when the thread is passed through the clip mouth, the thread cannot easily escape entrapment from the central region of the clip. The suture clip may be C-shape, V-shape, broken leg V-shape, heart shape or pentagonal shape. In another embodiment, the clip is a closed loop or elliptical in shape. To enhance operability, the hooks on the C, U or V shaped sutures are disposed on tabs which are laterally displaced with respect to each other such that, upon collapse and closure of the clip plates, the tabs interleave each other and interlock over the opposite clip plate. This feature enhances attachment to suture thread. The method for attachment on suture thread includes providing a clip having several specific features, passing the suture thread through the clip mouth and collapsing the clip plates together over the suture.

The filter device captures embolic material in a blood vessel and is placed in the blood vessel via a guide wire. The guide wire has a proximal end, a distal end and a stop near its distal end. The filter device includes an expandable frame of frame struts having a closed, radially compact form and an open, radially expanded form. The frame, in the radially expanded form, has frame struts forming a pair of facing frustoconical frame structures. Filter material is attached to one of the pair of frustoconical frame structures. In one embodiment, the filter material is a perforated membrane. The guide wire extends through the expandable frame and the expandable frame is freely movable over the guide wire (likewise, the guide wire is freely movable within the frame), both rotatably and longitudinally, except distally beyond the stop near the distal end of the guide wire. This mobility of the guide wire with respect to the expandable frame enables to guide wire to be guided by the operator through the blood vessel.

The self securing suture includes a suture having at least one terminal end and a toggle, formed of suture material, at the suture's terminal end. In one embodiment, the suture toggle is a bar. In another embodiment the suture is a wire and the toggle is a wire element toggle. The wire element toggle is a double strand segment or an open loop segment. The suture delivery system includes a slotted needle configured such that a protruding tab or leg of the toggle bar fits within slot of the needle. For wire sutures, the open loop wire element toggle fits within the slotted needle. In another embodiment, a depending wire tip, from the wire element toggle, fits within the slot in the needle. In either situation, after the needle pierces the bodily structure, tissue or organ, the tab, leg, depending wire tip or open loop wire segment coacts with the inboard portion of the bodily structure, tissue or organ, and, as the delivery needle is withdrawn, the toggle at the terminal end of the suture remains in the bodily structure, tissue or organ. The toggle is then fully deployed being generally normally disposed (perpendicular) to the length or axial center line of the suture.

The present invention relates generally to medical devices for applying hemostatic composition to a puncture or wound site with indwelling tubular element, such as catheter, introducer or tube therein, particularly a hemostatic pad with an opening therethrough in order to allow egress of the indwelling tubular element through the hemostatic pad as the hemostatic pad provide hemostasis at the hemorrhaging site. The device may be applied to, or removed from, the wound site while the tubular element is in place. A method for effecting hemostasis at a puncture wound, includes applying pressure proximal to the puncture wound, and directing a cationic biopolymer of glucosamine application surface of a closure pad against the puncture wound with force sufficient to prevent fluid from exiting the puncture wound. Then the pressure proximal to the puncture wound is removed and the force on the closure pad is maintained for at least a first predetermined time period. The force on the closure pad is removed if hemostasis is verified. The puncture wound may then be dressed over the closure pad, and the dressing and the closure pad removed after a second predetermined time period.
