Abstract: A drug delivery needle includes a body portion from which extends a penetration end that includes at least two sharp distal tips, the sharp distal tips being separated from each other by an arcuate trough that includes a cutting edge at least at a middle portion of the arcuate trough. At least the two sharp tips are made of a drug or include a drug therein or are coated with a drug. The drug is biodegradable.

Abstract: An ingestible pill (1220, 1320) is provided including a medication-delivery device (1224, 1324), which is configured to deliver a medication (52) and includes a patch (1230, 1330) (a) having upper and lower surfaces (1232, 1234) that face in generally opposite directions, (b) disposed within an enteric coating (22) in a compressed shape (1242), (c) configured to assume an expanded shape (1244) after the enteric coating (22) dissolves. The patch (1230, 1330) includes a chamber (1270) defined by (a) a substantially water-impermeable and substantially gas-impermeable, elastic layer (1274) shaped so as to define at least one window (1276) therethrough, and (b) a liquid-permeable and substantially gas-impermeable wetting layer (1278), which entirely covers the at least one window (1276) and is sealed to the elastic layer (1274) around the at least one window (1276).

Abstract: Embodiments are disclosed of a method of controlling timing and/or dosage of a transdermal drug patch. For example, a control device operative to move the patch to one or more of a plurality of operational relationships with a skin of a patient, including being fully engaged with the skin, partially engaged with the skin, and disengaged with the skin. The device may include a roller that peels a patch on and off the skin. Optionally a convention patch is used. In some embodiments a patch and/or an adaptor has a mobile zone and an immobile zone. In some embodiments, an active surface of the patch fully contacts the skin in an engaged state. For example the patch may be attached to the device on a passive portion thereof.

Abstract: An ingestible pill is provided that includes an enteric coating and a medication-delivery device, which includes (a) a patch having upper and lower surfaces that face in generally opposite directions, and (b) needles. The patch is disposed within the enteric coating, folded so as to define one or more creases, which define respective inner and outer crease sides, wherein at least 50% of the needles are coupled to the patch along the inner crease sides. The patch is configured to assume, after the enteric coating dissolves, an expanded shape, in which the patch has an outer perimeter. Other embodiments are also described.
