Therapeutic delivery device
A therapeutic delivery device that provides a controlled release of high doses of a therapeutic agent in a local area, sustains the high dose controlled release with a percutaneous port for refilling the device, and is versatile for use with multiple types of therapeutic agents and/or implant systems. A rate determining/controlled release membrane is used to decrease the molecular mobility of the therapeutic compounds thereby controlling the therapeutic release profile. The therapeutic delivery device includes a body defining an internal reservoir for receiving a therapeutic agent and including a first membrane for providing a controlled release of the therapeutic agent to the surgical site, a port in fluid communication with the reservoir, a sleeve configured to encapsulate the body, and a rigid housing configured to support the body and a portion of the sleeve, the rigid housing configured to release the body and the sleeve after the body and the sleeve are anchored position relative to the surgical site.
Assemblies for Identifying a Power Injectable Access Port
A method of using a power-injectable port includes obtaining the power-injectable access port, attaching a catheter to an outlet stem of the power-injectable access port, and implanting the power-injectable access port and the catheter into a patient. The method further includes identifying the power-injectable access port following the implanting, and in accordance with the identification, inserting a distal end of a needle through the septum and into the reservoir, and injecting contrast media through the needle at a rate of at least one milliliter per second. The power-injectable access port includes a housing, a septum, a reservoir, and an outlet stem in fluid communication with the reservoir. The power-injectable access port is rated for injection of contrast media at a flow rate of at least 1 milliliter per second. The power-injectable access port is structured for operation at a pressure in the reservoir of at least 35 psi.
Assemblies for identifying a power injectable access port
A method of performing a power injection procedure, including taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port. The access port defines one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum. The method further includes identifying the indicating radiographic feature on the x-ray, and in accordance with the presence of the indicating feature on the x-ray, flowing a fluid through the access port at a rate of at least about 1 milliliter per second.
METHOD AND APPARATUS FOR DELIVERING A THERAPEUTIC SUBSTANCE THROUGH AN INJECTION PORT
Adapters for utilizing a syringe or pen injector with a subcutaneous injection port to deliver a therapeutic substance through the injection port and methods of using the adapters are provided. A syringe adapter has a body having a first end and a second end. The first end of the body is configured to receive and engage the end of a syringe so that the cannula of the syringe is held at a fixed position with the respect to the adapter. The second end of the adapter configured to mate with a mating portion of the injection port. When the second end of the adapter engages the mating portion of the injection port, the adapter assures that the cannula of the syringe is properly aligned with the subcutaneous injection port and aasures that the cannula penetrates the injection port to the proper depth. Adapters for use with pen style delivery systems are also disclosed. Additionally, an adapter to facilitate loading a syringe with a therapeutic substance from a vial is disclosed.
Vacuum assisted percutaneous appliance
A luminal access device is provided that includes a luminal graft attached to a patient lumen. A percutaneous access device (PAD) is coupled to the luminal graft and adapted to stabilize a conduit in fluid communication with the luminal graft and an external medical device. A portion of said PAD adapted to be external to the patient and seal around said conduit. Infectious agent penetration at an insertion site of the PAD is reduced by providing a porous inner sleeve fluidly connected to a conduit. A vacuum or hydrodynamic source is fluidly connected to the conduit to create a fluid draw from the subject tissue through the inner sleeve to the conduit. The conduit is readily formed to have a bore and an outer conduit surface, the outer conduit surface being optionally nanotextured. The conduit bore is adapted to accommodate a medical appliance.

ACCESS PORT CAP SYSTEM AND METHOD OF USE
An access port cap system includes a cap having a body forming an interior reservoir therein, and a perimeter lip extending from a base of the body; and an adhesive member having a body forming an opening therein, and a double-sided adhesive tape contained between a top release liner and a bottom release liner; wherein the body of the adhesive member is configured to surround the circumference of an implanted port.
CONNECTION DEVICES FOR OSTOMY PROCEDURES
A connection and transfer device for post-operative surgical procedures includes a tubular member having a proximal portion, a distal portion, and a wall defining an inner surface and an outer surface. The distal portion is received within an internal body organ of a patient. The outer surface is configured to interface with an inner wall of the internal body organ. The inner surface of the tubular member defines a through bore dimensioned to allow passage of body fluids. At least one expandable member is disposed on the outer surface of the tubular member and is configured and dimensioned to be received within the internal body organ to engage the inner wall to retain the tubular member within the internal body organ and to prevent the body fluids from passing around the tubular member and into contact with external skin of the patient.
