Abstract: Gastric stimulation devices, systems and methods are provided, particularly for stimulating a gastric organ having an internal cavity. Such devices and systems are typically implanted outside of the gastric organ while the environment of the internal cavity is probed and monitored by one or more sensors. The sensor information may be used to affect the stimulation signals provided to the gastric organ by the devices and systems. Such feedback integration assists in providing treatments and stimulation programs that are tailored to the needs of the individual patient.

Abstract: A cavity (3) such as the urethra of a patient is lined by providing a lining device that comprises an eversible chamber (12) and a liner (16) connected thereto. Fluid pressure is applied to the chamber (12) to cause the chamber (12) to evert and advance into the cavity (3) such that the chamber (12) carries the liner (16) into the cavity. A vacuum is then applied to the chamber (12) to cause it to deflate. A part, such as a catheter or cable, can then be inserted into the cavity through the liner (16). If the cavity is the urethra of a patient, the liner shields the catheter from the distal part (1) of the urethra which is colonised with bacteria, and therefore reduces the risk of a urinary tract infection.

Abstract: A garden tool for planting seeds, comprising an elongate hollow cylinder through which a seed passes, a hopper attached to the first end of the cylinder through which the seed is dropped, an adjustable collar attached to the second end of the cylinder for measuring planting depth and, optionally, distance between planted seeds, a flange or hoe blade for furrowing or digging a planting row and for covering a planted seed, and optionally, an internal tray located in the hopper for holding seeds, and an adjustable elongate hollow cylinder.

Abstract: A forming machine includes a ram cylinder, a ram, the ram cylinder and a forward end of the ram defining a closed chamber, and an inlet to and an outlet from the closed chamber. A method of forming material is also disclosed.

Abstract: A body cavity lining means is disclosed having a fluid chamber (9) and at least one further means (23) for providing liner means rigidity, in use. Means (23) comprises a further fluid chamber. The provision of two fluid chambers provides much greater control over the insertion and removal of the lining means. The provision of two separate fluid chambers allows the rigidity of the chambers to be controlled independently of eversion. In one embodiment the lining means is used to assist in the insertion of an endoscope for performing a colonoscopy. In one embodiment the at least one further means for providing liner means rigidity comprises a resiliently deformable extendible elongate member. In another embodiment one of the two fluid chambers is formed partially by the endoscope or other semirigid member, and means is provided for advancing the endoscope within the colon.
