6632197, Oct 14, 2003

Filed:

Apr 16, 1999

Appl. No.:

09/293284

Inventors:

Thomas R. Lyon - Bronx NY 10467

International Classification:

A61M 2900

US Classification:

604107, 604106, 604264

Abstract:

There is disclosed a clear view cannula for use in surgical procedures having a tubular body, a cylindrical sleeve mounted about and slidably secured to the tubular body, and a plurality of shield members secured to the cylindrical sleeve. The cylindrical sleeve is slidably movable relative to the tubular body causing the shield members to expand and deploy such that the shield members retain torn and fragmented soft tissue within an anatomical cavity. Means are provided on the tubular body to co-act with means on the cylindrical sleeve to lock the expanded and deployed shield members and secure the tubular body within an anatomical body.

Appl. No.:

12/676396

Inventors:

Thomas R. Lyon - Brooklyn NY, US

International Classification:

A61B 10/00

US Classification:

600567

Abstract:

An aspiration apparatus is described that includes a guide and a set of needles. Guide preferably has an approximately conical shape with a decreasing diameter in the distal direction. A plurality of lumens extend between a distal end portion and a proximal end portion of guide. Lumens have distal openings in distal end portion and proximal openings in proximal end portion. Lumens are acute and oblique to the longitudinal axis and diverge from each other and the central longitudinal axis as they extend distally from distal openings. Needles have a tubular wall and are slidingly positionable in lumens. Needles include a longitudinal section of tubular wall that has a plurality of apertures that decrease in size in the proximal direction. Apertures define an approximately conically shaped area of harvest. Aspiration apparatus can connect to an external source of reduced pressure through guide or directly to each needle.

Abstract:

A tamping apparatus is described that includes a cannula that has a tubular wall that includes a distal end portion that defines a tamping face. The cannula defines a longitudinally aligned aperture or lumen that provides access for an insert and the injection of treatment materials such as a bone graft. The distal end portion of the cannula can also include a plurality of movable elements that can be a part of or connected to the tubular wall. The tamp apparatus can also include a cannula or stylet that can be moved within aperture of cannula and is employed to move elements between the first position and second position of tamp apparatus.

International Classification:

A61M 29/00

US Classification:

606191, 604109

Abstract:

An elongated cannula with an inner tube that is designed to cooperate with a corresponding outer tube. The cannula may include a cam mechanism, a plurality of flexible members designed to expand and deploy when the inner and outer tubes move relative to each other, and a pressure ring disposed on the outer tube. The inner and outer tubes are slidably moveable relative to each other in at least one direction.

Appl. No.:

Inventors:

Thomas Lyon - Brooklyn NY, US

International Classification:

A61M 29/00

US Classification:

606191000

Abstract:

A clear view cannula is described that includes a first tube, a second tube and a counter-pressure ring. The tubes are concentric, adjoined and define a longitudinally aligned aperture. The cannula has a first position for penetration or removal from a patient and a second position in which a shield structure is deployed within the patient. The ring provides a counter-pressure force that opposes the force applied by the shield structure in the second position and stabilizes the angular position of the cannula in the body of the patient. Detents in the tubes define the first position and the second position of the cannula and limit the travel between the tubes.

Abstract:

A spinal aspiration apparatus is described that includes a needle that has a shape suitable for the location of and penetration through a pedicle pathway of a vertebra The distal end portion of the spinal aspiration apparatus includes a plurality of apertures that are in fluid communication with a lumen of needle The size and angular orientation of the apertures are constructed using the principles of fluid mechanics to create separate and distinct harvest volumes of bone marrow within a body of vertebra A proximal end portion of needle includes an external interface that is adapted to provide a fluid tight coupling with an external source of reduced pressure. A handle is connected to proximal end portion that aids in the manipulation of needle
