Benefits of technology

[0008] Because the combined vascular access port and monitoring device may be implanted at the same time and in the same anatomical location, it is very convenient for the physician and procedurally cost effective. Also, because the monitoring device does not require patient involvement for effective use, it is not as susceptible to patient non-compliance as prior art monitoring devices. In addition, because the monitoring device permits continuous feedback; it is possible to detect patient symptoms that may occur infrequently and for short periods of time. Furthermore, because the monitoring device permits multiple measurements over a long period of time, it is possible to improve accuracy of measurements that lack repeatability by averaging multiple measurements over a period of time.

Problems solved by technology

As another example, infused inotropic or antihypertensive drugs require patient blood pressure monitoring because of possible hypo or hypertension side effects that may be life threatening.
In addition to inconvenience, these devices are not desirable due to lack of continuous monitoring and lack of patient compliance in outpatient settings.
Furthermore, because these monitoring devices require patient use, and because typical patients do not have professional health care training, the devices are susceptible to incorrect usage, potentially resulting in erroneous measurements.

Embodiment Construction

[0027] The following detailed description should be read with reference to the drawings in which similar elements in different drawings are numbered the same. The drawings, which are not necessarily to scale, depict illustrative embodiments and are not intended to limit the scope of the invention.

[0028] With reference to FIG. 1, a schematic plan view of a generic system including a vascular access port (VAP) 100 and physiological monitoring apparatus (PMA) 200 is shown. The system may be used to deliver therapeutic agents via the VAP 100 while monitoring the patient 10 with the PMA 200. Based on the patient's condition as measured by the PMA 200, the therapeutic regimen (e.g., dose, delivery rate, delivery schedule, etc. of therapeutic agent administered via the VAP 100) may be changed as needed. For example, if the patient 10 adversely reacts to the therapeutic agent delivered via the VAP 100 as measured by the PMA 200, the dose or delivery rate may be decreased or even terminated...

Abstract

A combined vascular access port and physiologic parameter monitoring device. The vascular access port and the monitoring device may be connected by a cooperative geometry. The vascular access port and the monitoring device may be implanted at the same time and in the same anatomical location (e.g., subcutaneous pocket). The monitoring device may include a telemetry unit that transmits physiological measurement data to a local data collection system (e.g., carried by the patient or located in the patient's home), which may re-transmit the data to a remote data collection system (e.g., located at a physician's office or clinic) via a suitable communication link.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 246,348, filed Sep. 17, 2002, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The present invention generally relates to vascular access ports. In particular, the present invention relates to vascular access ports having associated physiological sensors. [0003] Implantable vascular access ports (VAP) are used extensively in the medical field when recurrent infusions of therapeutic agents into a patient's circulatory system are required over extended periods of time. Such VAPs generally include a housing containing a reservoir and septum, with a catheter extending from the housing. The VAP housing is implanted in a subcutaneous pocket at an accessible location such as the arm, and the catheter extends from the housing to a remote vascular location to provide convenient, repeatable access to the patient's venous...
