Abstract: New devices for providing an indication to a nursing mother as to whether a baby is receiving milk during a breastfeeding session. Milk expressed from the mother's breast is caused to flow through a transparent passageway part of a nipple shield, disposed in in a position where it visible to the mother or a third party, before being supplied to a nipple of the device, from which the baby is enabled to suck. The device therefore provides an indication that the infant is receiving milk from the mother's breast. The visibility of the passageway is achieved by routing the passageway through a region of the device whose line of sight with the mother is not obscured by the baby when feeding, such as towards the periphery of the base layer of the device. The device passageway may also comprise a valve, and details of such valves are disclosed.

Abstract: A method for thermal bonding of an inverted balloon neck on a catheter, including placing an inverted balloon neck (84) on a shaft (86) of a catheter, and characterized by applying heat at an internal hollow (85) of the shaft (86) where the inverted balloon neck (84) is placed, while applying internal pressure to attach an external surface of the shaft (86) to the inverted balloon neck (84).

Abstract: A device, such as for use with lumen reentry, including a catheter including a balloon disposed at a distal end thereof, the catheter being formed with a first lumen through the balloon for passing therethrough a guidewire and a second lumen for inflation and deflation of the balloon, the catheter and the balloon being sized and shaped for entry between two layers of a wall of a body lumen, wherein upon expansion of the balloon when placed between the layers, a distal portion of the first lumen that passes through the balloon is bent with respect to a portion of the first lumen proximal to the balloon and is directed towards the body lumen.

Abstract: A micro-catheter (10) including a hypo-tube including a proximal section (13) and a distal section (12) and a sharp tip (11) formed at a distal end of the distal section (12), characterized in that the proximal section (13) of the micro-catheter (10) is formed with a plurality of cuts (23) which are not perpendicular to a longitudinal axis of the proximal section (13), the cuts (23) being made partially around a circumference of the proximal section (13) with uncut portions separating the cuts (23) from one another.
