摘要： Fixation and protective components for use with implantable medical devices, such as access ports and catheters, are disclosed. In one embodiment, a protective sleeve is employed about a catheter so as to distribute compressive loads and ensure patency of the catheter lumen, even in areas prone to pinch-off. A catheter assembly in one embodiment thus comprises an elongate catheter tube that defines at least one lumen. A protective mesh sleeve is disposed about an external portion of the catheter tube so as to cover at least a portion of the longitudinal length of the catheter tube. The protective sleeve is configured to distribute a compressive load on the catheter tube so as to ensure patency of the at least one lumen of the catheter tube.

摘要： A safety needle device and method of supplying fluid to a vascular access port is described. The device may include a base member, a handle member, and a compressible member positioned between the handle member and a compression plate. The compressible member is coupled to a proximal end of a needle. Following the delivery of fluid to a vascular access port, the needle is removed by moving the handle member away from the base member, which collapses the compressible member, flushing fluid into the vascular access port to substantially replace a volume of the needle.

摘要： Assemblies for identifying a power injectable vascular access port are described. One assembly includes a vascular access port, a first identifiable feature, a second identifiable feature, and a third identifiable feature. The first identifiable feature is incorporated into the access port and identifies the access port as suitable for flowing fluid at a fluid flow rate of at least 1 milliliter per second through the access port. The second identifiable feature is incorporated into the access port and identifies the access port as suitable for accommodating a pressure within the cavity of at least 35 psi. The third identifiable feature is separated from the access port and confirms that the implanted access port is both suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port and for accommodating a pressure within the cavity of at least 35 psi.

摘要： A safety needle device and positive flush mechanism for use with a vascular access port. In one embodiment, the combination needle assembly includes a needle, a body and a base, the body being collapsible to expunge fluid therefrom as the needle is withdrawn from a vascular access port. In another embodiment, the combination needle assembly includes a needle, a housing and a reservoir, the housing squeezing the reservoir to expunge fluid therefrom as the needle is withdrawn from the port. In another embodiment, the needle assembly includes a compression plate and balloon extension, the compression plate forcing fluid out of the balloon extension as the needle is withdrawn from the port. In all embodiments, the needle assembly is configured to provide a positive flush to overcome negative pressures in the vascular access port, while also providing a locking mechanism to prevent accidental needle sticks.
