Systems and methods for identifying an access port

An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is engraved or otherwise defined by the access port, so as to be visible after implantation via x-ray imaging technology.

Needle Guide with Selectable Aspects

A needle guide assembly for inserting a needle into the body of a patient in order to access a subcutaneous target, such as a vessel, is disclosed. In one embodiment, the needle guide assembly comprises a needle guide body that is configured to at least indirectly and removably attach to an image producing device, such as an ultrasound probe. The needle guide body defines at least first and second elongate guide channels. Each guide channel defines a unique insertion angle with respect to a longitudinal axis of the ultrasound probe. Further, each guide channel is configured to accept needles of differing gauges. In other embodiments other needle guide assemblies are disclosed that include multiple guide channels for inserting a needle at a variety of insertion angles into the patient's body. Related methods are also disclosed. In yet other embodiments, needle guide assemblies including needle stop features are disclosed.

TUNNELER FOR BI-DIRECTIONAL TUNNELING

A tunneler for producing a subcutaneous tunnel in connection with the placement of a catheter within a body of a patient is disclosed. In one embodiment, the tunneler comprises an elongate tunneler member and a sheath. The tunneler member includes a handle on its proximal end and a tapered distal end. The sheath defines an elongate lumen inside which the tunneler member is initially received. The tunneler member is configured to define a tunnel through subcutaneous tissue while disposed in the sheath, then is removable from the sheath lumen thereafter. The sheath is configured to remain within the tunnel so that a catheter can be inserted through the sheath within the tunnel. The sheath is splittable in one embodiment so as to enable its removal from the tunnel while leaving the catheter in place. 1. A tunneler , comprising:an elongate tunneler member including a handle on a proximal end and a tapered distal end; anda sheath member defining an elongate lumen inside which the tunneler member is received, the tunneler member configured to define a tunnel through subcutaneous tissue, the tunneler member being removable from the sheath lumen after defining the tunnel, the sheath configured to remain within the tunnel so that a catheter can be inserted through the sheath within the tunnel.2. The tunneler as defined in claim 1 , wherein the sheath is splittable to enable removal of the sheath from around the catheter within the tunnel while the catheter remains in place within the tunnel.3. The tunneler as defined in claim 1 , wherein a distal portion of the sheath is shaped to provide a substantially smooth transition between the distal portion of the sheath and an adjacent portion of the tunneler member.4. The tunneler as defined in claim 1 , wherein the sheath is sized to extend within the tunnel between a subcutaneous pocket for a medical device and a vessel entry site.5. The tunneler as defined in claim 4 , wherein the tunneler member is configured to define the ...
