Abstract: A medical device for infusing medical substances has activation buttons accessible on an exterior of a device housing. The activation buttons and corresponding electrical switches within the housing are configured to prevent inadvertent activation of the buttons and therefore inadvertent operation of the switches to initiate a process such as medical substance delivery to a user. The device employs overlap of respective time traces initiated by activation of the activation buttons to determine whether the activation is intended and valid. The respective time traces do not have to be initiated simultaneously or in any particular sequence. The activation buttons can be elastomeric overmolded buttons set within cutouts in the housing, and, when depressed, make physical contact with respective switches.

Abstract: An introducer needle assembly including a compressible section between a rigid needle and a hub. Once a vessel is entered as determined by blood entering a syringe, the compressible section of the introducer needle is occluded by compressing the compressible section with a thumb and a finger. Neither blood nor air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. An operator then can begin threading a guidewire down a divide which is now easier to enter because blood is not coming out of the hub thus obscuring a lumen.

Abstract: A flexible implantable contraceptive disc device is disclosed which can be inserted inside the female body, such as inside the uterus, is disclosed. The disc device can be bent and inserted into a laparoscopy tube, which allows it to be delivered to an appropriate location inside a female subject. The disc device has three layers, a central core silicon reservoir containing an active ingredient, such as a contraceptive progesterone, which is sandwiched and encased by upper and lower porous silicon casings. The casings are porous to the contraceptive, allowing controlled release over a prolonged period of time. The lower casing has a series of micro-hooks around a circumference, allowing the disc device to be attached to a desired tissue by rotating the disc device such that the hooks engage with the desired tissue. Such a device is easier to insert, and to remove, than a rod-like rigid plastic T-shape IUDs which are considerably larger, also and more expensive to manufacture.
