US Patent:

8048108, Nov 1, 2011

Filed:

Feb 4, 2009

Appl. No.:

12/365397

Inventors:

Randy R. Sibbitt - Helena MT, US

Assignee:

Abbott Vascular Inc. - Santa Clara CA

International Classification:

A61B 17/08
A61D 1/00

US Classification:

606213

Abstract:

A vascular closure device comprised of a sheath-delivered expandable, umbrella-like device with structural radial members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure umbrella-type devices that effect closure by opening of the umbrella to cover an opening, the present invention effects closure of the aperture with closure of the umbrella. The closure can be maintained by a retainer lock that slides down the members, causing contraction, bringing the members into a compressed configuration (e. g. , a parallel orientation of linear members) and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.

International Classification:

A61M 5/00

US Classification:

604187000

Abstract:

A reciprocating syringe that can be used in connection with existing syringe barrels and fittings. Some embodiments comprise a frame, adapted to retain two existing syringe barrels. The frame can accommodate fittings on one or both barrels. The invention also provides a plunger complex, comprising two plungers, each adapted for use with one of the syringe barrels. The two plungers are coupled such that pushing of each plunger into its barrel causes the other plunger to pull outwards relative to its barrel. The two plungers can be coupled by a flexible line attached to one plunger, routed from the plunger out of the corresponding barrel into the other barrel, and attached to the other plunger. The invention contemplates various frame configurations to accommodate desired line and pulley performance characteristics. Other embodiments comprise a frame adapted to retain an existing syringe barrel, and an auxiliary actuator mounted with the frame. Such an actuator can provide a syringe-like plunger operation, or can comprise other manipulable structures. The auxiliary actuator can be coupled to a plunger adapted for use with the syringe barrel, such that pushing the plunger into the barrel causes the actuator to move in a reversible manner, and moving the actuator in the reverse manner causes the plunger to pull outwards relative to its barrel. The invention also comprises various materials, methods of making, geometries and arrangements of parts, and accommodation of various specific existing syringe designs and applications.

International Classification:

A61B 17/08

US Classification:

606213000

Abstract:

A vascular closure device comprising a retrievable sheath-delivered contractible, clip device with structural radial or terminal members with terminal and non-terminal hooks that engage the vessel wall. Unlike other vascular closure clips, this device is delivered on the outside rather than the inside of sheath. Closure of the tissue opening can be effected by the feet of the clip engaging the puncture, aperture, or wound edges and memory characteristics of the device cause a contraction of the members, bringing the members into apposition and the wound edges together, permitting immediate vascular closure and healing of the blood vessel. The device can be delivered and recovered by an intravascular sheath.

International Classification:

A61B 17/08

US Classification:

606213000

Abstract:

Tissue eversion apparatuses and methods suitable for use, as examples, with vascular closure devices. The tissue eversion apparatuses comprise a tissue engaging element, disposed within a delivery sheath. The delivery sheath protects the tissue engaging element and the surrounding tissue during use. The tissue engaging element can extend from the sheath and engage the tissue near an aperture in a tissue wall. Motion of the tissue engaging element away from the tissue can urge the tissue wall near the aperture to evert from the tissue wall, allowing, as examples, aperture closure apparatuses and methods to be conveniently employed.

International Classification:

A61B 17/10

US Classification:

606139000

Abstract:

A vascular closure device comprised of a sheath-delivered cincture or noose-like device or knot comprised of suture, wire, or other suitable materials, that is placed on the external surface of a puncture wound, and closed. The vascular closure cincture is delivered by a sheath, and after closing is left resident on the external surface of a tissue puncture wound.

Abstract:

A tissue closure device including a tissue eversion apparatus, and a first and a second, redundant closure element that are placed on the external surface of a tissue puncture wound to enhance the efficacy of closure. The first closure element and the second closure element closure are left resident on the external surface of or in proximity to the tissue puncture wound in order to provide redundancy of closure.

US Classification:

604207, 604227, 29428

Abstract:

The present invention provides automatic syringes that can be held with one hand in a pencil-grip in which the fingers (thumb or index finger) operate a forwardly based valve that along with selection of needle diameter and length, control the ingress or egress of fluid from the automatic syringe. These finger-controlled one-handed automatic syringes can be used in image-directed procedures such as ultrasound (sonography)-directed procedures in which the ultrasound probe is controlled with one hand and the automatic syringe with the other, although many other applications are readily apparent to those skilled in the art including biopsy, epidural injections, administration of anesthesia, and detection of blood vessels and body cavities as well as other applications.
