Abstract: An endoscopic tool has an elongate cylindrical cannula with an open hooked end insertable into the body of a patient with a trocar element providing a laser powered flux of energy for precise incision and optional cauterization of tissue. A conventional pointed trocar may be used with the hooked cannula to permit forcible insertion of the hooked cannula end to the selected surgical site. In the alternative, a laser energy conveying trocar may be used with the hooked cannula or homeostatic insertion into the patient's body. The active distal end portion of the trocar may be provided with a selectively shaped energy-delivering tip element. The energy-delivering tip element may be provided with a subsurface heating region in which a selected implanted material converts received laser energy into heat for application to tissue held in the hooked open end portion of the cannula.

Abstract: A collapsible jogging infant stroller that has a contractible lower frame portion having a rear end supporting two wheels, an intermediate portion and a front fork end supporting a front wheel. A contractible upper frame portion has a lower end pivotally attached to the lower frame portion and an upwardly and rearwardly extending intermediate seat portion supporting a flexible infant seat holder and an upper handle end. A stabilizer strut is connected to the lower frame portion and the upper frame portion to secure the frame portions together for safe and smooth carrying of an infant. A releasable locking means secures the stroller in its upright erect position for use, and when released, permits contraction of the upper and lower frame portions inwardly upon themselves as to move the stroller to a collapsed condition for transportation and storage.
