Abstract: An apparatus for effecting the closure of a stoma, the apparatus comprising a stimulator arranged to provide a signal for stimulation of implanted contractile tissues positioned proximate to the stoma in order to facilitate closure of the stoma.

Abstract: The present invention relates to a method and apparatus for the treatment of a heart condition such as angina and/or congestive heart failure. Conditions such as angina, caused by inadequate blood flow to the coronary arteries, are treated in this invention by implantation of smooth muscle tissue wrapped around the ascending aorta. The smooth muscle tissue is stimulated electrically, by the implanted stimulator, to contract at timed intervals relative to the hearts' cycle. The contraction assists blood flow to the coronary vessels.

Abstract: The present invention provides a method and apparatus for treating a prolapse related condition. The apparatus includes an implantable stimulator arranged to be implanted within a patient. The stimulator provides a signal for stimulation of tissue in the pelvic region.

Abstract: The present invention relates to an apparatus and method for treating erectile dysfunction. One of the causes of erectile dysfunction is venous leakage, where one or more veins carrying the blood from the penis are unable to retain sufficient blood within the penis to maintain erection. Embodiments of the present invention propose implanting contractile tissue sphincters around the base of the penis and/or around one or more veins, and stimulating the contractile tissue to contract when an erection is required to be maintained. Stimulation is provided by an implantable stimulator.

Abstract: The present invention relates to an implant for managing a medical condition. In particular, it relates to medical treatments which employ smooth muscle implant and discloses a method of augmenting a smooth muscle implant for management of a human medical condition. Augmentation may be by a number of methods. It may be by utilising neurotrophic or trophic factors to assist growth of the smooth muscle tissue or nerve growth within the smooth muscle tissue, or revascularisation of the smooth muscle tissue. It may be by utilising tissue engineering to grow smooth muscle tissue. It may be by adding proliferative smooth muscle cells and/or smooth muscle stem cells for the smooth muscle.

Abstract: The present invention relates to a method and apparatus for treating fecal incontinence. A smooth muscle sphincter is implanted about the distal part of the large intestine in the region of internal anal sphincter or the anal canal, the rectum or the sigmoid colon. The smooth muscle sphincter is electrically stimulated by a stimulator device, in order to contract the smooth muscle sphincter and maintain continence. Stimulation is ceased or varied in order to allow the smooth muscle sphincter to relax and the patient to defecate.

Abstract: The present invention relates to a method and apparatus for controlling urinary incontinence. An implantable stimulator is utilised to apply stimulation to a sphincter or neosphincter about the urethra, in order to maintain coaptation of the urethra and urinary continence. Feedback is utilised in order to vary the level of stimulation applied to the sphincter in order to enable control over the sphincter. Control may be implemented by a user setting levels, by biofeedback, by a clinician.

Abstract: The present invention provides a device for the stimulation of smooth muscle tissue. The device includes a stimulator arranged to provide a signal to the smooth muscle tissue to control response of the smooth muscle tissue, and an interface arranged to allow programming of a controller of the stimulator. The interface may interact with an external controller. The device finds use in controlling smooth muscle tissue, such as a neosphincter, for the control of urinary or faecal incontinence in a patient.

Abstract: A medical condition is treated using electrical stimulation of contractile tissue, such as a sphineter, as well as electrical stimulation of afferent nerves to illicite a neuron-modulation response. The device (1) and method is particular useful for treating urge incontinence where the tissue is a smooth muscle neo-sphineter (2) about the urethra and the nerves are in the pelvic region.

Abstract: An implantable electrode arrangement (1) for stimulating excitable tissue, in particular the neosphincter to control urinary incontinence. The electrode is in the form of a extending peg with a pair of electrode elements (2, 3) extending from a base (4). The elements are arranged to fit over the tissue to be stimulated and have electrodes (5, 6) on the inner surfaces of the peg portions. The tissue located between the peg portions receives stimulation. Also disclosed are methods of treating urinary incontinence by electrically stimulating a band of smooth muscle and electrode having an insulating member and electrodes on the inner surface such that an electric field applied to tissue is confined.

Abstract: A container inspection system wherein diffused light and collimated light provide backlighting to image a container (10) by a color camera (18). Light strobed through a ring light (36) and parabolic reflector (39) is diffused at a diffusion laminate (46). Light strobed through a ring light (60) and parabolic reflector (64) is collimated at lens (68) and aligned with the diffused light by reflector laminate (48). Diffused light is filtered by a blue band-pass filter (42) and collimated light is filtered by a red band-pass filter (66) and camera (18) segregates the container image according to blue and red color planes.

Abstract: An optical inspection system wherein a camera (14) images recessed surfaces of a workpiece through a lens (16). Video signals to the image are provided to a computer (30) that compares selected parameters of the image with predetermined values. Based on that comparison, computer (30) selectively signals a controller (20) to activate a rejector assembly (24). Lens (16) is a microlens of the wide angle type to provide an open image of the recessed surface to camera (14). An illumination system (54) directs diffused light through a gap (52) between the lens (16) and the workpiece (10) to illuminate the workpiece.

Abstract: An object-oriented development system for developing control schemes for facilities includes a device diagramming component for describing a physical description of a facility and a logical definition of a control scheme for the facility. The device diagramming component includes a mode for selecting device symbols representative of equipment or control functions used in facilities. The device symbols are selected from an object-oriented repository containing a plurality of device symbols and device objects. Certain types of device symbols relate to device objects containing logical instructions and configuration information relating to the represented equipment or control functions. The device diagramming component also includes a mode for interrelating in a graphical manner the selected device symbols and their corresponding device objects into a device diagram representing the physical description of the facility and the logical definition of the control scheme for the facility.

Abstract: A method is disclosed for providing a single-tasking disk operating system with multitasking capability in a real-time computer system for building access control or the like. A number of reentrant, terminate-and-stay-resident application programs are loaded into a host microcomputer. As each application program loads, it passes its unique code segment and instruction pointer parameters to a look up table. For the last application program to be loaded, the program segment prefix of the application program residing in the disk operating system is copied and stored. When a timer interrupt prompts the program switching logic, the code segment and instruction pointer parameters of the then-executing program are compared with the values in the look-up table. If no match is found, program switching is postponed.
