20090030381 | Arced Hypodermic Needle - A hypodermic needle for delivering a bolus of a pharmaceutically active agent to the posterior chamber of the eye having a lancet disposed at the distal tip and a lumen disposed along a longitudinal axis within. The lancet may be formed by an angled linear cut coming to a point at the distal tip of the needle, or an arc-shaped cut beginning at the needle tip parallel to the longitudinal axis and gradually arcing upward to roughly perpendicular to the longitudinal axis. Additionally, cuts, grooves, channels, or teeth may be added to the surface of the lancet in a regular or irregular pattern for the purpose of increasing surface tension on the drug bolus. | 01-29-2009 |
20090216203 | Intimacy medical needle designed for nerve stimulation through soft tissue and microadhesiolysis of adhered soft tissue and medical instrument using the same - A medical needle comprises a main body extending from a proximal end to a distal end, and a tip portion formed at the distal end of the body. The tip portion has a first inclined region, the cross-sectional area of which decreases toward the distal end and has a pair of surfaces inclined with an angle of 15° to 20°. The tip portion has a second inclined region extending from the first inclined region, the cross-sectional area of which decreases toward the distal end and has a pair of surfaces inclined with an angle of 30° to 45°. A tip is formed at the point of juncture of the pair of surfaces of the second inclined region. Tapered portions are formed on both sides of the first inclined region. Each tapered portion is inclined at an angle of 5° to 15°. Curved portions are formed at the points of juncture of the tip and the tapered portions. | 08-27-2009 |
20100094231 | DEVICES AND METHODS FOR TISSUE MODIFICATION - Methods and apparatus are provided for selective surgical removal of tissue. In one variation, tissue may be ablated, resected, removed, or otherwise remodeled by standard small endoscopic tools delivered into the epidural space through an epidural needle. The sharp tip of the needle in the epidural space, can be converted to a blunt tipped instrument for further safe advancement. The current invention includes specific tools that enable safe tissue modification in the epidural space, including a barrier that separates the area where tissue modification will take place from adjacent vulnerable neural and vascular structures. A nerve stimulator may be provided to reduce a risk of inadvertent neural abrasion. | 04-15-2010 |
20130226103 | Port cannula for the puncturing of port catheters - A port cannula for puncturing implantable or implanted port catheters includes a cannula tube with a ground surface, which is formed from a ground cut inclined with respect to a center axis of the cannula tube by a ground-cut angle and from two facet cuts lying at an angle to each other, and of a cannula tip which is provided by the ground surface and which is oriented via a first bend in the direction of the center axis of the cannula tube. The ground cut and the facet cut are adapted to each other in such a way that, on the one hand, during puncturing, a bending of the cannula is least reduced and, on the other hand, the pain caused to the patient is kept within an acceptable range. | 08-29-2013 |
20140236104 | PUNCH-REDUCING CANNULA - The present invention relates to a new bevel or grinding for a punch-reducing cannula, i.e. a cannula which reduces punching particles, and, in particular, to a punch-reducing cannula having a beveled or ground end as well as to a method for manufacturing a cannula which reduces punching particles. | 08-21-2014 |
20150032067 | METHODS AND APPARATUS FOR SELECTIVELY OCCLUDING THE LUMEN OF A NEEDLE - A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient. | 01-29-2015 |
