Abstract: A bioresorbable drug-eluting biopolymer suture-free blood vessel anastomosis devices can be deployed to join two blood vessels and resorbed by the body over a predetermined time period after the blood vessel has become joined. The anastomosis device can include a hollow tube that is inserted interconnect the two vessels to be jointed. A non-piercing suture is wrapped around the vessel to secure the anastomosis. The anastomosis device can include hollow tube that extends along an axis from a first end to a second end. The ends can be fitted with elements that facilitate mechanical attachment of the vessel to the anastomosis device and provide for a secure seal.

Abstract: A motor-driven vehicle includes a first vehicle body with a fixed cantilever disposed at a front end thereof, and a second vehicle body with a fixed post disposed in front of the cantilever, and a connecting device interconnecting the first and second vehicle bodies removably. The connecting device includes a projection extending upwardly from a front end of the cantilever of the first vehicle body, and a spring-biased retaining block disposed movably on the post of the second vehicle body. The retaining block is biased to a position, where the projection is confined between the retaining block and the post so as to prevent relative movement of the first and second vehicle bodies.

Abstract: A motor-driven vehicle includes a first vehicle body with a sleeve tube, a second vehicle body with an insert rod disposed telescopically within the sleeve tube, and a locking device including a pull rod, a retaining block and a resilient member. The pull rod is movable on the first vehicle body between a locking position and a release position. When the pull rod is disposed at the locking position, the retaining block extends through a hole in the sleeve tube and engages a selected one of holes in the insert tube of the second vehicle body. When the pull rod is disposed at the release position, the retaining block is removed from the holes in the insert rod. The resilient member biases the pull rod to the locking position.

Abstract: A handle-adjusting device for adjusting position of a handle relative to a vehicle frame includes a valve cylinder with a valve rod, and a control rod that is formed with a pressing face and a release face. When the control rod is operated to align the pressing face with an upper end of the valve rod, the valve rod is disposed at a retracted position so as to enable rotation of the handle relative to the vehicle frame. When the control rod is operated to align the release face with the upper end of the valve rod, the valve rod is disposed at the extended position so as to prevent rotation of the handle relative to the vehicle frame.

Abstract: A latch device for a foldable steering head on an electric motorcycle has a base, an inner wheel, and an outer ring. The inner wheel is mounted on the base and has a radius-varying actuating shaft axially penetrating the inner wheel and a latching block radially and movably mounted inside the inner wheel. The latching block has an abutting end and is operationally pushed by the actuating shaft. The outer ring rotatably surrounds the inner wheel and has an inner periphery and multiple detents defined on the inner periphery to operationally engage the abutting end of the latching block so that the latch device locks. By simply pushing the actuating shaft to a radius-narrowing area, the latching block is released from push of the actuating shaft and can move inward to allow the outer ring to rotate. Therefore, the steering head can be conveniently adjusted.

Abstract: A connecting device for a joystick controller on an electric wheelchair has a post, two rods and a base. The post has two brackets attached to the post. The two rods are pivotally attached respectively to the two brackets in parallel with each other. The base is pivotally attached to the two rods to achieve a four-bar linkage. The joystick controller is adjustably and detachably mounted on the base. The four-bar linkage keeps the joystick controller oriented in a constant direction when the base moves relatively to the electric wheelchair. Therefore, the joystick controller has a fixed orientation relative to the wheelchair.

Abstract: A cart has a folding support for handlebars, which includes a lower rod secured on a front part of a frame, a pivotal rod pivoted to an upper end of the lower rod, and an upper tube positioned in a linearly displaceable manner around the pivotal rod from a lower end; the pivotal rod has a lengthways extending slot; the upper tube has two opposing holes; handlebars of the cart are connected to an upper end of the upper tube; a connecting element is passed through the opposing holes and the slot such that the upper tube will prevent the pivotal rod from moving relative to the lower rod when it is around the pivotal rod and the lower rod, and such that the support can be folded with the pivotal rod pivoting on the lower rod when the upper tube is apart from the lower rod.
