604164060 | Having tapered portion to provide cutting tip | 10 |
20100081994 | Self Retaining Laparoscopic Trocar System-Zisow Trocar Sleeve System - A new concept in laparoscopic trocar systems is presented that could be used with most presently available laparoscopic trocars. The Ethicon XCEL 5 mm trocar is used as the basis for this presentation; however, any other size or system of trocars similarly configured would be compatible with the ZTSS being presented. | 04-01-2010 |
20110137253 | DILATING STYLET AND CANNULA - An instrument set is provided that has a tapered configuration that facilitates the insertion of the instrument set into a patient. | 06-09-2011 |
20120150119 | Delivery System for Implanting Nasal Ventilation Tube - Delivery systems and methods of creating an accessory maxillary ostium and implanting a ventilation tube for purposes of ventilation, irrigation, infusion or procedural work are described. The delivery systems include an introducer and an associated ventilation tube. An irrigation and/or infusion catheter may be advanced through the ventilation tube in order to irrigate or express the contents of the sinus cavities. A secondary irrigation and/or infusion catheter or a balloon catheter may be advanced through an outer irrigation and/or infusion catheter, deeply into the sinus cavity, in order to irrigate or express the contents of the sinus cavities. Moreover, the balloon catheter may alternatively or additionally be employed to for dilation of the natural ostium. Still further, a device for delivering drugs, fluids or the like, may be coupled to the ventilation tube for delivery of same. | 06-14-2012 |
20130261554 | INTRAVENOUS CATHETER APPARATUS - The invention relates to an intravenous catheter apparatus comprising a tubular catheter having a proximal end and a distal end, a needle defining an axial direction and having a needle shaft and a needle tip at a distal end of the needle shaft, wherein said needle shaft extends through said tubular catheter such that said needle tip of said needle protrudes from said distal end of said tubular catheter, and wherein said needle shaft comprises an engagement means adapted to engage with a needle guard slidably arranged on said needle shaft in order to prevent said needle guard from sliding off said needle tip. | 10-03-2013 |
20140114254 | SELF-COILING STYLET NEEDLE DEVICE - A medical device includes an elongate single-wire memory-metal body with a complete length that includes a proximal stylet length, an intermediate self-coiling stylet length, and a distal stylet length that is generally straight and non-self-coiling. The moment of force of the self-coiling stylet length is less than the moment of force of the medical endoscopy needle that is resistant to the stylet's self-coiling force. The device may further include being incorporated into an endoscopy needle system where the single-wire stylet body is disposed through a lumen of a medical endoscopy needle. | 04-24-2014 |
20140114255 | SELF-COILING STYLET NEEDLE DEVICE - A medical device includes an elongate single-wire memory-metal body with a complete length that includes a proximal stylet length, an intermediate self-coiling stylet length, and a distal stylet length that is generally straight and non-self-coiling. The moment of force of the self-coiling stylet length is less than the moment of force of the medical endoscopy needle that is resistant to the stylet's self-coiling force. The device may further include being incorporated into an endoscopy needle system where the single-wire stylet body is disposed through a lumen of a medical endoscopy needle. | 04-24-2014 |
20140171873 | SURGICAL ACCESS SYSTEM - A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either device within the brain. | 06-19-2014 |
20150011941 | PHARMACEUTICAL PREPARATION-INJECTING INSTRUMENT - A pharmaceutical preparation injecting instrument includes an outer needle and an inner needle. The outer needle has a straight tube shape having a distal side opening and a proximal side opening, and has a reference puncturing part on a distal side. The inner needle is configured to be removably inserted in the outer needle, and has a periphery puncturing part on a distal side. The inner needle is configured to allow the periphery puncturing part to appear from, or disappear into, the distal side opening in accordance with an advancing or withdrawing operation on the base side. When the inner needle is removed from the outer needle, the instrument is capable of injecting, from the distal side opening, a pharmaceutical preparation supplied from the proximal side opening. The outer needle guides the inner needle to project the periphery puncturing part to a side opposite the reference puncturing part. | 01-08-2015 |
20160022311 | SURGICAL NEEDLE - The disclosure provides examples of a surgical needle for entering a joint space, such as the hip joint, through tissue. | 01-28-2016 |
20160074623 | TRANSVASCULAR ACCESS DEVICE AND METHOD - Transvascular access devices and methods for transvascular access are provided. The transvascular access devices can include a guidewire lumen and a guide tube and stylet disposed in a second lumen. The guide tube can be used to control the orientation of the stylet and provide additional support for the stylet. The methods include providing a second entry point in a vessel of a patient remote from a first entry point. A vascular catheter can enter the vascular system of a patient at a first entry point and be advanced to a second entry point. A guide tube can be advanced out the second lumen of the vascular catheter with a stylet advanced out of the guide tube to pierce the vessel wall and skin of the patient at the second entry point. A catheter can be introduced to the vascular system at the second entry point. | 03-17-2016 |
