Title: Method and apparatus for tissue excision and removal by fluid jet
Inventor: DOHERTY REX E
IPC: A61B17/32
Filed: 1993-12-13
Abstract: A method and apparatus for the excision and removal of tissue, such as the lens of the eye includes a pencil-like handpiece have a cannula probe extending from the distal end thereof. The probe includes an inner jet tube to direct a high pressure jet of fluid toward a tissue target, and an outer concentric aspiration tube to aspirate and remove fluid and tissue. The jet tubeis recessed proximally within the concentric aspiration tube, and the aspirationtube has an end area significantly larger than the end area of the jet tube. These factors cooperate so that the negative pressure exerted by the aspiration tube creates a suction force that offsets and exceeds the force of the fluid jet. The jet tube is connected to a fluid pressure system including a positive displacement pump, a pressure regulator, safety release, control valve, and a pulse former. The jet tube emits pulses of high pressure fluid that impinge reiteratively on the target, creating shock waves that fracture and emulsify thelens tissue, and the fluid also acts as a solvent to transport the emulsified tissue into the aspiration tube. The handpiece also includes a vacuum bypass port disposed to be selectively occluded by a finger of the surgeon, so that vacuum pressure may be released immediately when needed.

Title: Swivel basket, bracket and easy loading stand
Inventor: CONWAY RICHARD
IPC: A47G7/04
Filed: 1993-11-09
Abstract: The swivel basket bracket and stand has been designed to: 1) allow easy loading of flowering plants into basket. This is achieved by having no horizontal bars on the basket, therefore allowing that potted plants once removed from their plant pots can easily slid down into the basket between the vertical arms (1) of the basket; 2) the easy loading stand function is threefold (A) it overcomes the problem, when loading a flower basket on a flat surface the overhanging blooms can get damaged, (B) because the basket swivels on the stand the need to move around the basket is removed when loading with plants, it is simply swivelled to whichever area of the basket you are working on, (C) it can also be used as jardiniere; 3) when the basket is filled to satisfaction it can be removed from the easy loading stand, it can then be placed on the bracket to be swivelled, so that all areas of the basket may get its equal share of sunlight. The relationship between all three items can be seen in the figure.

Abstract: DETERMINATION OF LYMPH NODES ENRICHED IN TUMOR REACTIVE CELLS, THEIR PROLIFERATON, AND THEIR USE IN ADOPTIVE CELLULAR THERAPY            ABSTRACT OF THE DISCLOSURE Broadly, the present invention in one aspect is directed to a method for reliably determining lymph nodes enriched in tumor reactive cells, e.g., CD4+ tumor-specific lymphocytes, often called T-helper cells or T-helper lymphocytes. This method includes the steps of administering to a patient an effective amount of a radiolabeled locator which specifically binds a marker produced by or associated with neoplastic tissue, e.g. cancer. Time then is permitted to elapse following the administration for the radiolabeled locator to preferentially concentrate in any neoplastic tissue and for unbound radiolabeled locator to be cleared, so as to increase the ratio of photon emissions from neoplastic tissue to background photon emissions in the patient. After the time has elapsed, the patient is accessed (e.g. preferably, surgically; note: use of a laproscope may be impractical, though use of such instruments is not precluded in the present invention) with a radiation detection probe for determining lymph node sites exhibiting accretion of the radiolabeled locator by detecting with the probe elevated levels of radiation at the lymph node sites. The lymph node sites exhibiting such elevated levels of radiation then are removed and subjected to gross visual analysis, though such sites alternatively/additionally may be subjected to histological analysis, e.g. hematoxylin and eosin (H&E) histologic evaluation. Those determined and removed lymph nodes that also are determined to be tumor-free by gross observation or free of gross metaswtatic disease (i.e., those lymph nodes that visually appear normal, but which take-up antibody) then are selected and cultured to proliferate tumor reactive cells, e.g., tumor-specific T lymphocytes therein. The selected lymph nodes are subjected to mitogenic stimulation. Advantageously, then, the lymph nodes are cultured in the presence of, for example, Interleukin-2 (IL-2), anti-CD3 monoclonal antibody, and, optionally, neoplastic tissue which may be autologous or allogeneic tumor. The tumor reactive cells, e.g., T lymphocytes, proliferated then can be used in accordance with adoptive immunotherapy regimens for mitigating (moderating) the progression of tumor. The expanded or proliferated tumor reactive cells, e.g., Tlymphocytes, are an effective therapeutic agent in the treatment of cancer.

Title: Front view vehicle mirror system
Inventor: VO THUAN Q
IPC: B60R1/10
Filed: 1994-08-11
Abstract: The front view vehicle mirror system (FVVMS) is a mirror assembly mounted on a vehicle to provide the operator with an alternative view of objects ahead that are obstructed by some darken vehicles, such as a tinted car, van, truck, or trailer. The FVVMS includes a plastic or plastic-like housing enclosing two vertical mirrors, one is standard and the other is convex, a solid supporting pole fastened vertically at the front corner of the vehicle, and a connecting part which links the plastic or plastic-like housing and the supporting pole, . The FVVMS mounted at the vehicle front end on the driver side is particularly useful for the operator to make a safe left turn at intersections, and the FVVMS on the passenger side is helpful for the driver to monitor front objects or road condition ahead when he is trapped in traffic jams or on busy highways. That is, FVVMS provides drivers with an alternative way of observing front objects, while their direct line of sight is blocked by a view obstructing vehicle.

Title: Methods and compositions for gene, tumor, and viral infection therapy, and prevention of programmed cell death (apoptosis)
Inventor: ROIZMAN BERNARD
IPC: A61K48/00
Filed: 1993-02-26
Abstract: The present invention relates to methods of treatment of programmed cell death (apoptosis) through the use of the HSV-1 gene  .gamma.1 34.5 or the product of its expression, ICP34.5. The gene and its expression have been demonstrated to be required for HSV-1 neurovirulence, and in particular, to act as an inhibitor of neuronal programmed cell death which allows for viral replication. Use of the gene therapy, or the protein itself, can be expected to result in inhibition of programmed cell death in various neurodegenerative diseases. This invention also relates to novel vectors for gene therapy, including modified herpes virus. Methods are presented for conducting assays for substances capable of mimicing, potentiating or inhibiting the expression of .gamma.1 34.5 or the activity of ICP34.5. Also, methods are disclosed for the treatment of tumorogenic diseases, including cancer, and for treatment of herpes and other viral infections using inhibitors of .gamma.1 34.5 expression or ICP34.5 activity.
