An apparatus for sealing a puncture extending through tissue to a blood vessel includes a guidewire including an expandable tamp, a retaining sheath for covering the tamp, and a delivery sheath including a primary lumen for receiving the guidewire therethrough and a secondary lumen for delivering sealing compound into the puncture. The guidewire is advanced into the puncture with the tamp in a contracted condition, the tamp is expanded within the vessel after retracting the retaining sheath, and the guidewire is retracted to seal the puncture from the vessel. The delivery sheath is advanced over the guidewire, and sealing compound is introduced into the puncture through the delivery sheath. After introducing the sealing compound, the delivery sheath is removed, and an introducer sheath is advanced over the guidewire to provide access to perform a medical procedure via the vessel after removing the guidewire.

Garniture tongue of a garniture device of a rod machine arranged for compressing a material. The garniture tongue includes a rod guide surface and the garniture tongue being composed at least in part of a steel alloy with high titanium carbide content. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

A mouth rinsing device comprising a pump housing and a reservoir. These two housings are arranged in series; i.e., the reservoir is attached to the base of the pump housing. A riser tube having a head on its end is situated on the pump housing and is fixed there by means of a lock so that only the head protrudes. When the reservoir is attached the lock is simultaneously released, so that the riser tube is able to slide into the reservoir and the intake opening is situated just above the base. After the reservoir is removed, the riser tube may be pushed in again manually. The riser tube is subsequently fixed in the retracted position by locking the head to the base of the pump housing.

An apparatus for stabilizing vertebrae while permitting a range of motion therebetween may include first and second fasteners for engaging adjacent vertebrae and a motion preserving device that can be coupled to the first and second fasteners. The motion preserving device may include a longitudinal member that includes an array of load-bearing elements. The longitudinal member may be configured to permit the load-bearing elements to move relative to each other and/or relative to other portions of the member. In some embodiments, the longitudinal member is relatively inflexible along a longitudinal axis and relatively flexible in a direction transverse to the longitudinal axis.

Catheters having a tapered, atraumatic distal tip are provided. In one embodiment, the outer surface of the distal portion of the catheter has a generally non-cylindrical and substantially triangular cross-sectional configuration. The inner surface cross-sectional configuration of the distal portion of the catheter may match the outer surface, or it may have a cylindrical or oval configuration. The terminal orthogonal surface of the distal catheter tip is chamfered or rounded or contoured. In another embodiment, inner and/or outer catheter surfaces have a three dimensional surface conformation and may be dimpled or grooved. The grooves may be generally liner or curved or helical or in a spiral configuration. Dimpled and/or grooved surface discontinuities may be provided in connection with and in addition to lubricious coatings, surfaces, and the like.

An endoscopic system and method that is adaptable for therapeutic applications as well as sensor operation and is capable of producing 3-dimensional human vision simulated imaging with real dynamic convergence, not virtual convergence. Applications may include use in any space, including but not limited to, intra-abdominal cavities, intra-thoracic cavities, and intra-cranial cavities. Further, two or more diagnostic/sensor probes may be used, with at least two being the same kind to create the 3-dimensional effect, such as but not limited to, camera, ultrasound, and magnetic-resonance imaging. Diagnostic/sensor probes are each mounted to the end of a different arm, with the other ends of the two arms both being attached to the same hinge that allows them to turn freely on the same axis from side-to-side within a 180 degree angle range of movement on the distal end of a main tubular shaft system. Medical, as well as other applications, are contemplated.

Apparatus is provided for use with a biologically-compatible-fluid pressure source, the apparatus including an elongate carrier, adapted to be inserted through a proximal opening of a body lumen, and a piston head coupled to a distal portion of the carrier. The piston head is adapted to form a pressure seal with a wall of the lumen after the carrier has been inserted into the lumen, and to be advanced distally through the body lumen in response to pressure from the fluid pressure source. The apparatus is configured to facilitate distal advancement of the piston head by facilitating passage of fluid out of the lumen from a site within the lumen distal to the piston head. The apparatus additionally includes an optical system, coupled to the carrier in a vicinity of the distal portion, the optical system having distal and proximal ends. The optical system includes an image sensor, positioned at the proximal end of the optical system; an optical member having distal and proximal ends, and shaped so as to define a lateral surface, at least a distal portion of which is curved, configured to provide omnidirectional lateral viewing; and a convex mirror, coupled to the distal end of the optical member, wherein the optical member and the mirror have respective rotational shapes about a common rotation axis.

A ride surface for water ride attractions and the like is provided. The ride surface is fabricated from a reinforced membrane material tensioned over a supporting framework. The tensioned membrane ride surface serves the dual role of providing structural support for water flow and riders thereon while at the same time providing an impact safe surface that is non-injurious to riders who may fall thereon. The tensioned membrane can be adjusted actively and/or passively in order to accommodate different and varied ride experiences. Optionally, the shape of the membrane ride surface can be changed either dynamically or passively by special tensioning techniques and/or by using auxiliary support structures such as air bladders, pressure/suction, foam supports or/or the like.

An adjustable infusion catheter includes a flexible tube containing one or more axial lumens that allows fluid to flow from the proximal end of the catheter to the distal end. A syringe or infusion pump is the usual pressure source for fluid at the proximal end. A plurality of small-diameter holes are provided in a fenestrated area near the distal end of the tube to disperse fluid throughout a targeted region within the patient's body. The length of the fenestrated area of the catheter body is adjusted by a slidable sheath which can be positioned along the length of the fenestrated area so that its exposed length substantially matches the targeted region. The ends of the slidable sheath include a seal portion to prevent leakage around the ends of the sheath. Heat shrinkable plastic material can be used to form the sheath and the end seals.
