62results about How to "Prevent over-insertion" patented technology

An anatomical space access device having an elongate body; an insertion tip at a distal end of the elongate body; an anatomical space sensor disposed at the distal end of the elongate body, the sensor being adapted to sense a parameter identifying an anatomical space other than a vasculature space and to generate a signal; and an indicator operatively connected to the sensor to receive the signal and to indicate access of the sensor to the anatomical space. The invention also provides a method for providing access to an anatomical space outside of a vasculature space, including the following steps: inserting a distal end of an instrument through a tissue volume into the anatomical space outside of a vasculature space, the instrument comprising an anatomical space sensor; and generating a location indication of the anatomical space sensor.

Devices and methods are disclosed for expanding a spinal canal. An implantable device having a shaft with a first cross-sectional dimension distinct from a second cross-sectional dimension can be inserted into an opening in a lamina and rotated 90 degrees to hinge the lamina away from the spinal canal. The implant can have one or more radiused edges, a bulleted tip, one or more lateral extensions for fastening the implantable device to bone, one or more hinged lateral extensions, one or more arcuate protrusions for biting into adjacent bone, an enlarged proximal head to prevent over-insertion, and/or a sleeve disposed therearound to reduce friction. Various embodiments of an insertion apparatus that can be selectively coupled to the implantable device are also disclosed, along with methods of expanding a spinal canal in minimally-invasive procedures using an implantable device and/or an insertion apparatus.

A target-treating system treats a target disposed within a bone of a patient. The system comprises a probe configured to be inserted into the bone and navigated therethrough toward the target. The probe comprises a shaft that includes a proximal end, a distal end, and a main body extending between and interconnecting the proximal end and the distal end. The distal end is configured to engage the target such that, upon activation of the probe, the target is treated.

An airway [(10, 310, 410, 510, 610, 710, 810, 1110, 1210, 1310, 1410, 1510, 1610, 710, 1810, 2010, 2110, 2210, 2310, 2410, 2510, 2610, 2710, 2810, 2910, 3010, 3110, 3210, 3310, 3810) device for human or animal use, the device includes an airway tube (12) having a first end (14) and a second end (16), wherein the device further includes a shoulder (26), the shoulder extends laterally from and substantially perpendicular to the airway tube, the shoulder is adapted to contact the faucial pillars of the human or animal patient to prevent over-insertion of the device in use.

A rectal thermometer for measuring the temperature of a patient including a disk or oval-shaped member having a circumferential edge and first and second sides. Along the edge is a temperature display that is viewable during the temperature taking process without having to first remove the thermometer from the anal canal. The first and second sides form a concave shape and include an actuation switch and battery compartment. Connected to the main housing via a probe guard portion is a controlled-depth temperature sensing probe which can be fully inserted into the anal canal without concern for over-insertion. The probe guard portion, which may be formed of flexible material, is adapted such that its thickness gradually increases proximate the main housing and serves to slow down the entry of the probe within the anal canal. Finally, the rectal thermometer includes a holder having a proximal end for covering the housing and a distal end for covering the probe. The distal end also houses an enclosed portion having rattle balls which allow the thermometer holder to serve as an amusement device for the child.

An eating/oral care device has a concave or curved head and spaced-apart, broad protrusions in the interior space of the head, for children or challenged adults having difficulty with a conventional fork or spoon. The protrusions are fewer and more spaced-apart, and have a larger diameter to length to ratio, than toothbrush or other conventional bristles. The protrusions have a lower diameter to length ratio than nubs or bumps. The head may be an elongated, curved arm, having low or no sidewalls and an upwardly-extending rear end serving as a food and safety stop. Multiple longitudinal rows of protrusions may extend along the curved upper surface of the arm. The preferred utensil handle is spherical, which allows the user to grasp the device comfortably and naturally in various orientations, and to handle the utensil in a way that improves food-pick-up and aiming at the mouth.

An apparatus for treating urinary incontinence, comprising a node; a support section adapted for providing urethral support attached to the node; and, an anchoring section adapted for resisting movement of the apparatus attached to the node; wherein the node is no longer than 30% of the entire length of the apparatus comprising the node, support section and the anchoring section together.
