TRANSRADIAL ACCESS DEVICES, SYSTEMS, AND METHODS
First Claim
1. A device for providing access to a vessel or other luminal organ and to prevent overperforation of the same, the device comprising:
- a needle having a needle tip and at least one current element positioned thereon or embedded therein at or near the needle tip;
a sheath positioned around at least part of the needle, the sheath defining an aperture at a distal sheath end, an interior space around the needle positioned therein, and having a tapered distal end configured for percutaneous insertion into a vessel or other luminal organ, wherein at least a portion of a wall of the sheath is comprised of translucent or transparent material; and
a protractor in communication with the needle, whereby engagement of the protractor causes the needle tip to protract from the sheath through the aperture, and whereby release of the protractor causes the needle tip to retract through the aperture into the sheath,wherein the device is configured so that when the needle tip punctures the vessel or other luminal organ underneath skin after puncturing the skin and is advanced along with the sheath so that the distal sheath end is also positioned within the vessel or other luminal organ and so that fluid within the vessel or other luminal organ is in contact with the needle tip, activation of the at least one current element can facilitation vasodilation of the vessel or other luminal organ and the fluid can enter the interior space of the sheath through the aperture and be visually detected within the sheath through the portion of the sheath wall comprising the translucent or transparent material to indicate that the distal sheath end is positioned within the vessel or other luminal organ so to prevent overperforation of the vessel or other luminal organ.

Abstract
Transradial access devices, systems, and methods. An exemplary device of the present disclosure for providing access to a vessel or other luminal organ and to prevent overperforation of the same comprises a needle having a needle tip and at least one current element positioned thereon or embedded therein at or near the needle tip, a sheath positioned around at least part of the needle, and a protractor in communication with the needle, whereby engagement of the protractor causes the needle tip to protract from the sheath through the aperture, and whereby release of the protractor causes the needle tip to retract through the aperture into the sheath. Activation of the at least one current element can facilitation vasodilation of the vessel or other luminal organ.

12. A system for providing access to a vessel or other luminal organ and to prevent overperforation of the same, the system comprising:
-
a needle having a needle tip and at least one current element positioned thereon or embedded therein at or near the needle tip; a sheath positioned around at least part of the needle, the sheath defining an aperture at a distal sheath end, an interior space around the needle positioned therein, and having a tapered distal end configured for percutaneous insertion into a vessel or other luminal organ, wherein at least a portion of a wall of the sheath is comprised of translucent or transparent material; and an actuator configured to facilitate movement of the needle within the sheath, whereby a first operation of the actuator causes the needle tip to protract from the sheath through the aperture, and whereby a second operation of the actuator causes the needle tip to retract through the aperture into the sheath, wherein the system is configured so that when the needle tip punctures the vessel or other luminal organ underneath skin after puncturing the skin and is advanced along with the sheath so that the distal sheath end is also positioned within the vessel or other luminal organ and so that fluid within the vessel or other luminal organ is in contact with the needle tip, activation of the at least one current element can facilitation vasodilation of the vessel or other luminal organ and the fluid can enter the interior space of the sheath through the aperture and be visually detected within the sheath through the portion of the sheath wall comprising the translucent or transparent material to indicate that the distal sheath end is positioned within the vessel or other luminal organ so to prevent overperforation of the vessel or other luminal organ. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for accessing a mammalian bodily vessel and to prevent overperforation of the same, the method comprising the steps of:
-
protracting a needle tip of a needle from a sheath of a device, at least a portion of a wall of the sheath comprising translucent or transparent material and the sheath comprising an interior space around the needle positioned therein; percutaneously puncturing mammalian skin using the needle tip; puncturing a mammalian bodily vessel under the mammalian skin using the needle tip so that the needle tip and a tapered distal end of the sheath of the device surrounding the needle tip access a lumen of the mammalian bodily vessel and operating at least one current element positioned upon or coupled to at least one of the needle and a wire positioned at least partially within the wire to cause vasodilation of the mammalian bodily vessel; and retracting the needle tip into the sheath of the device upon visual detection of blood from the mammalian bodily vessel within the interior space of the sheath of the device through the portion of the sheath wall comprising the translucent or transparent material so to prevent overperforation of the vessel or other luminal organ. - View Dependent Claims (20)
