Integrated system for the ballistic and nonballistic infixion and retrieval of implants

Provided are methods and apparatus for the use of magnetic traction to maintain the patency of a tubular anatomical structure, whether a vessel, duct, the trachea, bronchus, bile duct, ureter, vas deferens, fallopian tube, or portions of the digestive tract, as to constitute means for extraluminal stenting. An extraluminal stent consists of a perimedial or medial intravascular and an extravascular component. The intravascular component consists of ferromagnetic spherules implanted aeroballistically or stays implanted by means of a special hand tool, while the extravascular component consists of a pliant jacket or mantle that has magnets mounted about its outer surface. A catheter adapted for use as the barrel of a gas-operated implant insertion gun is so devised that it can be used independently to perform an angioplasty and thereafter have its free or extracorporeal end inserted into the airgun to initiate implantation of the intravascular component without the need for withdrawal and reinsertion through the introducer sheath. When the implants must be spaced too closely together to be controlled by hand, a positional control system is used to effect discharge automatically. Spherules that consist entirely of medication or that have a radiation emitting seed as the core can be implanted with the same apparatus. A glossary of terms follows the specification.

Body lift-assist walker device

The present invention provides a body lift-assist walker device for gait training is provided by the invention. The patient wears a pressurized body suit over all or a portion of his lower body, and the suit is attached to the walker device. A positive pressure or vacuum condition is applied to the interior of the suit, so that the differential pressure condition across the suit offloads a portion of the patient's body weight to the ground through the supportive walker device to make it easier for him to walk or run. The walker device also includes a lift-assisted body weight support device operated by a constant force mechanism like a pneumatic air cylinder that can lift the patient from a sitting position to a standing position with minimal physical effort. The device provides a portable and convenient system for persons undergoing physical therapy for treatment of gait or balance problems following an injury, stroke, or neurological disorder, or for use by elderly or disabled persons who have encounter difficulties in the sit-to-stand movement or walking.

Wheel chock

A wheel chock (10) configured for placement under a resting rubber tired wheel (W), such as a wheel found on a powered vehicle, to maintain the wheel (W) at rest is disclosed. The wheel chock (10) broadly includes a body (12) that defines an internal chamber (14) in communication with an open face (16) presented by the body (12). The body (12) presents a prism-like configuration having a generally triangular shape and includes a pair of oppositely spaced sidewalls (18, 20), a rear wall (22) extending between and adjoining the sidewalls (18,20), and a wheel-supporting surface (24) extending between and thereby enclosing the walls (18,20,22). The wheel-supporting surface (24) presents a low profile, arcuate leading tire-engaging edge (34). The arcuate leading edge (34) substantially complements the contour of the tire and enables the chock (10) to be easily placed under the wheel (W) in an optimal operating position i.e., in close adjacent alignment with the wheel (W) so that at least a portion of the majority of the circumferentially extending treads of the rubber tire of the wheel (W) engage at least a portion of the chock (10) with a minimal exertion of force and effort by the user. The internal chamber (14) in communication with the open face (16) enables the body (12) of the chock (10) to be stackably nested within another similarly configured wheel chock to provide a compact, space-efficient storage of the chocks that facilitates ready portability for transportation of a pair or more of the chocks in the vehicle.

Respirator having valve with an ablated flap

A respirator 10 that has a mask body 12, a harness 13, and an exhalation valve 14. Both the harness 13 and the exhalation valve 14 are secured to the mask body 12. The exhalation valve 14 comprises a valve seat 20 and a flap 22 that has a surface 57 that has been ablated. Through use of an ablated flap, the flap characteristics can be better fashioned to achieve desired valve performance. The valve flap can be fashioned to remain closed under any orientation but also to open with minimal force or pressure from the wearer's exhaled air. A valve having these qualities provides a respirator that is more comfortable for a person to wear, which can be particularly beneficial to workers who wear respirators for extended time periods.
