Abstract: A package assembly for an elongate surgical device in which two or more elongate surgical devices are secured and oriented in a coiled configuration so that a distal end of a first elongate surgical device may be inserted into a proximal end of a second elongate surgical device. In this assembly, the elongate surgical devices remain in a protected coiled state in the package while in the sterile field and so that a medical professional may prep the elongate surgical devices without removing from the package prior to use. In this package assembly, the elongate surgical devices reduce space required and eliminate the risk of damage to the devices and/or the chance of the elongate surgical devices become unsterile prior to use.

Abstract: An elongated deployment shaft carrying a needle deployment assembly with needles carrying sutures and a stabilizer. A catcher tube over the shaft having a catcher assembly at a distal end may retain a portion of the needles when passed through the tissue into engagement with catcher assembly. The catcher and needle deployment assemblies are configured to asynchronously engage the plurality of needles when moved distally beyond the catcher assembly. A sheath over the catcher tube may sandwich the tissue against the stabilizer when expanded. A first actuator may move catcher tube distally to decrease distance between proximal and distal ends of the stabilizer expand it and may move the sheath distally to sandwich the tissue. A second actuator may deflect the needles outward to move proximally through the tissue and engage the catcher and return a portion of each not retained by the catcher to a distal position.

Abstract: Systems and methods are provided for suturing tissue. An elongated deployment shaft carries a needle deployment assembly with needles carrying suture material. A needle catcher is disposed over the shaft and configured to engage and retain at least a portion of each of the needles carrying the suture material when the needles are passed through the tissue to be sutured to a proximal position.

Abstract: Systems and methods are provided for suturing tissue. An elongated deployment shaft carries a needle deployment assembly with needles carrying suture material and a stabilizer that is reconfigurable between an unexpanded insertion profile and an expanded profile. A catcher tube over the shaft having a catcher at a distal end may retain at least a portion of the needles carrying the suture material when the needles are passed through the tissue to be sutured into engagement with the catcher. A sheath over the catcher tube may sandwich tissue to be sutured against the stabilizer when expanded under control of first actuator. A second actuator may control the needles.

Abstract: The present technology is directed to introducer needle assemblies comprising a tapered needle; as well as to kits comprising a tapered needle, a guidewire and a dilator and sheath; as well as to methods of introducing a dilator to the interior of a patient's body as part of an interventional procedure.

Abstract: The present technology is directed to a dilator centering device and assemblies and methods using same. In particular, a dilator centering device in accordance with the disclosed technology can be used with a sheath hub assembly. In one embodiment, a dilator centering device includes a lumen capable of receiving a dilator shaft and centering a dilator shaft with respect to the sheath hub as the dilator shaft enters the sheath hub. In one embodiment, the dilator centering device can be attached to the sheath hub during manufacturing or it can be attached at the use site. In one embodiment, the dilator centering device can be integrated with and non-removable from the sheath hub. The embodiments disclosed herein are illustrative and do not limit the scope and spirit of the disclosed technology.

Abstract: The present invention is directed to a dual diameter guide wire that is steerable inside the lumen of a patient, and provides greater ability to access small areas such as the interior of a needle, or the interior of a patient's lumen such as small blood vessels, thereby improving access to a patient's body during interventional procedures. The present invention is also directed to medical devices for interventional applications, methods of accessing the interior of a lumen of a patient's body and methods of preparing a guide wire.

Abstract: A medical catheter for inserting into a body includes a bump tubing section with proximal and distal ends, wherein the proximal end is configured to mate with a hub. The bump tubing section has an intermediate portion extending away from the proximal end with a substantially constant outer diameter and thickness, and a taper portion adjacent the distal end with generally decreasing inside and outside diameters to provide a gradually increasing flexibility toward the distal end of the bump tubing section. The bump tubing section is comprised of a polymer having a predetermined flexural modulus. A tip section is disposed distally of the distal end of the bump tubing section comprising a distal liner and a distal cover such that at least a majority of the tip section has a substantially constant stiffness and a flexural modulus substantially equal to or greater than the predetermined flexural modulus.

Abstract: The present technology is directed to introducer needle assemblies comprising a tapered needle; as well as to kits comprising a tapered needle, a guidewire and a dilator and sheath; as well as to methods of introducing a dilator to the interior of a patient's body as part of an interventional procedure.

Abstract: The present invention is directed to syringe assemblies comprising detachable needle assemblies, that are configured in such a manner as to minimize the dead space after deployment of the syringe piston and injection of the material in the syringe into a patient's body, as well as with bevel indicators that provide guidance as to optimal angles at which to inject the needles into patients.

Abstract: The present invention is directed to kits comprising syringe assemblies having detachable needle assemblies, as well as shield apparatuses to protect the needle assemblies. The syringe assemblies are configured to minimize the dead space after deployment of the syringe and injection of the material in the syringe into a patient's body, as well as to include detachable needle assemblies, such that different needle assemblies can be interchanged on a single syringe barrel.

Abstract: A safety needle assembly comprises a cannula holding member, a cannula fixed to the cannula holding member, and a safety device mounted on the cannula holding member. The cannula holding member includes one or more outwardly directed fins extending longitudinally along at least a portion of the cannula holding member.
