Direct Fluid Path for Inline Dual Lumen Port
Embodiments disclosed herein are directed to a dual, in-line port having a direct fluid path between the proximal reservoir and the stem. The port includes a conduit extending through the distal reservoir and defining a lumen in fluid communication with the proximal reservoir and the stem. The axis of the conduit lumen is aligned with stem lumen to minimize any tortuous fluid pathway and reduce fluid flow resistance. The port can further include a needle guard extending over the distal reservoir and configured to prevent an access needle from impinging on the conduit when accessing the distal reservoir. Embodiments can further include a removable reservoir insert that defines the distal reservoir.
Systems And Methods For Radiographically 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 included on an insert that is incorporated into the access port so as to be visible after implantation via x-ray imaging technology.
Implantable Medical Device for Improved Placement and Adherence in the Body
A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.
Implantable medical devices
An implantable medical system that comprises a gas unit for supplying gas that is essentially oxygen and at least one functional cells unit configured to receive oxygen from the gas unit so as to maintain the cells in a viable condition. The cells unit is flexible. Several embodiments are disclosed.
Low-Profile Single And Dual Vascular Access Device
A low-profile access port for subcutaneous implantation within a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable catheter-bearing needle access to the port without difficulty. In one embodiment, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end, and a receiving cup. The receiving cup is funnel shaped to direct a catheter-bearing needle into the conduit via the inlet port. The conduit is defined by the body and extends from the inlet port to an outlet defined by a stem. A bend in the conduit enables catheter advancement past the bend while preventing needle advancement. A valve/seal assembly is also disposed in the conduit and enables passage of the catheter therethrough while preventing fluid backflow. The body includes radiopaque indicia configured to enable identification of the access port via x-ray imaging.
Implantable medical device for improved placement and adherence in the body
A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.
Side Access for Dual Lumen Ports
Embodiments disclosed herein are directed to a dual, in-line port having a body defining a first reservoir and a second reservoir arranged along a central port axis. Dual, in-line ports can be advantageous since the port can be placed through an incision site, along the central port axis, requiring a smaller incision site than side-by-side dual ports. Further, the port can include a stem extending from a side surface of the body, between the first and second reservoirs, the stem can be angled such that an axis of the catheter can extend parallel to the central port axis. The angled, side stem can mitigate disparities in fluid paths and fluid resistance between the first and second reservoirs and the respective catheter lumen. Embodiments can include a pivotable stem configured to allow an axis of the stem to be repositioned relative to the central port axis.
Radiopaque and septum-based indicators for a multi-lumen implantable port
An implantable multi-lumen access port including indicators for ascertaining characteristics of the port is disclosed. In one embodiment, the access port comprises a housing that defines a first reservoir and a second reservoir. A first septum and second septum are respectively coupled with the housing to provide selective access to the first and second reservoirs. Each septum includes a plurality of protrusions defined about a periphery thereof that are palpable after implantation of the port in a patient to determine a relative position of the first septum with respect to the second septum. A radiographically observable indicator is also included on a base of the housing, so as to provide information relating to a characteristic of the dual-lumen port, such as suitability for power injection of fluids. The indicator in one embodiment includes a substantially rigid radiopaque component.
Implantable dual reservoir access port
A dual reservoir access port includes a base having proximal and distal fluid reservoirs. The fluid reservoirs each comprise a bottom and a side wall. A dual prong outlet stem projects from a distal end of the base and comprises a first prong and a second prong. A first fluid channel extends through the first prong to the distal reservoir, and a second fluid channel extends through the second prong to the proximal fluid reservoir. A puncture shield is disposed between at least a portion of the second fluid channel and the bottom of the distal fluid reservoir. A needle-penetrable septum is disposed atop of each of the fluid reservoirs. A cap is placed over and around the port base compressing and sealing the septa against the base. A locking collar may be placed over a dual lumen catheter to lock the catheter to the dual prong outlet stem.
High flow rate dual reservoir port system
Devices and methods for obtaining high flow rates in a port catheter system, and devices and methods for using a high flow rate port catheter system are disclosed. In one embodiment, a reservoir is dedicated for aspiration and a separate reservoir is dedicated for infusion. Fluid flow channels associated with aspiration are larger than the fluid flow channels associated with infusion. The catheter connected to the port can have an offset tip configuration. Methods for accessing the port are also disclosed.
