Appl. No.:

11/595582

Inventors:

Thomas L. Meyer - New Albany OH, US

International Classification:

A61B 17/58
A61M 29/00
A61F 2/44

US Classification:

606 90, 606191, 623 1716

Abstract:

A method and a distracter for replacing a removed, intervertebral disc with a prosthesis. An inter-body distracter is inserted within the intervertebral space between adjacent vertebrae, the vertebrae are distracted and are supported by the distracter. A fluid, curable polymer is injected into the intervertebral space and around the distracter and then the polymer is cured to a semi-rigid, pliable, elastically deformable state. The distracter is then disabled from supporting compressive forces applied by the vertebrae and remains in place. The preferred distracter is a scissors jack having intermediate bearings joined by links to support feet. One of the bearings has a threaded lateral bore and the second bearing has a lateral bore. A rod extends through the bores and has a threaded portion extending from a first end of the rod and threadedly engaging the threaded bearing. The inside diameter of the second bore is greater than the outside diameter of the threaded portion of the rod so the rod is axially slidable through the second bore. A thrust bearing is fixed on the threaded rod and positioned laterally outwardly of the second bearing for forcing the second bearing laterally toward the first bearing upon rotation of the rod in one direction and for permitting the rod to be withdrawn from the bearing by rotating the rod in the opposite direction and disengaging it from the first bearing. Alternative distracters are also disclosed.

International Classification:

A61F 9/00
A61F 9/013

Abstract:

An apparatus includes a body and a pair of rigid legs extending from the body. The body includes an engagement feature configured to engage a deployment instrument. The legs are parallel with each other. Each leg has a sharp tip. The legs both extend along a plane. The body defines a guide opening. The guide opening is oriented transversely relative to the plane associated with the legs. The guide opening is sized to receive a cannula having a generally flat profile. The guide opening is configured to guide the cannula through a sclerotomy at a substantially tangential orientation.

International Classification:

A61F 9/00
A61M 25/06
A61M 25/02

Abstract:

An apparatus includes a body, a needle, a catheter, and an actuator assembly. The needle extends distally from the body. The needle has an inner wall defining a needle lumen. The needle lumen is in fluid communication with a fluid port of the body. The catheter is slidably disposed in the needle lumen. The catheter has a catheter lumen. The first actuator assembly is configured to translate the catheter within and relative to the needle. The apparatus may also include an actuator assembly that is configured to rotate the needle relative to the body. The apparatus may be used to first deliver a leading bleb of fluid to the subretinal space in a patient's eye via the needle. The apparatus may then be used to deliver a therapeutic agent to the subretinal space in the patient's eye via the catheter.

A61B 50/30
A61B 46/23

Abstract:

An apparatus includes a pad assembly, an injector assembly, an injector driver, and a fluid source. The pad assembly is sized and configured to be placed on a forehead of a patient. The injector assembly includes a body, a flexible cannula, and a needle. The body is configured to be removably secured to the pad assembly. The cannula is sized to be inserted through an incision in an eye of a patient. The needle is slidably disposed in the cannula. The injector driver is operable to drive the needle longitudinally relative to the flexible cannula. The fluid source assembly is in fluid communication with the needle.

International Classification:

A61F 9/00
A61M 25/06

Abstract:

An apparatus has a first fluid conduit, a second fluid conduit, a connector member, an first tubular member, a second tubular member, and an inner cannula. The connector member has first and second passageways in which the first and second fluid conduits are positioned, respectively. A portion of the second tubular member is positioned within the lumen of the first tubular member. A proximal portion of the inner cannula is fixedly secured within the lumen of the first tubular member. The inner cannula lumen is in fluid communication with the first and second fluid conduits via the lumen of the first tubular member and the lumen of the second tubular member. The inner cannula may be inserted into the subretinal space of a human eye to deliver a leading bleb of fluid and then deliver a therapeutic agent, without having to withdraw the inner cannula from the subretinal space between the acts of delivering the leading bleb delivering the therapeutic agent.
