Abstract:
The present invention relates to a system and method for utilizing a primary component and an auxiliary component in concert upon locations in close proximity to one another. Examples of benefits from this invention include medical applications such as biopsy procedures. Other benefits include minimization of cancerous cell seeding by using embolic material to block the spread of cancer cells from biopsied locations. Other benefits include detection of tissues, or masses such as cancerous tumors, through the use of a contrast agent. Additional benefits include prevention of bleeding or other migration of biological material from sites that have been medically operated on. Other benefits include blocking direct contact between a biopsy stylet which has taken a biopsy sample, and the walls of a path within the patient through which said biopsy stylet is withdrawn afterwards; this can minimize risks of cancerous debris being spread along said path.

[0001]    This application claims priority from, relies upon, and relates to Provisional Application No. 61/915,484, filed on Dec. 12, 2013. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    Currently, tasks such as percutaneous medical operations involve both risks and inconveniences. Some of these risks include the risk of cancerous cell seeding, which can occur when a biopsy procedure creates loose cancer cells, and which can result in these cells spreading to undesired locations in a patient&#39;s body. This mechanism of cell seeding is linked in medical literature to the metastasis of cancerous cells. The problem of cell seeding is particularly pronounced where the type of cancer being biopsied has a high incidence of seeding, such as cancers of the breast, liver or kidney. 
         [0003]    Other risks and inconveniences of tasks such as percutaneous medical operations include the incidence of bleeding due to the operation, as well as risks that fluids or other biological material will spread in undesired ways due to said medical operations. 
         [0004]    Current techniques for minimizing the risk of cell seeding, the risk of bleeding, and the risks of spreading biological material due to medical operations, may involve injection of embolic agents or other material. However, current techniques may include the use of two separate instruments, and attempting to use two separate instruments in concert with one another can create logistical and operational issues. Due to the limitations of these instruments or due to the difficulties of operating the two instruments in concert, such techniques do not always adequately reduce cell seeding, bleeding, or other complications. 
         [0005]    Current techniques for conducting biopsies of potentially cancerous biological matter often comprise a biopsy stylet being inserted in a manner that creates a needle tract, and withdrawn through this tract in the opposite direction after obtaining a biopsy sample. However, this poses the risk that cancerous debris or other hazardous matter will fall off of the biopsy stylet as said biopsy stylet is being withdrawn. 
         [0006]    Currently, tasks such as medical imaging involve inefficiencies and inaccuracies, some of which are due to the logistical and operational difficulties which are inherent in the attempts to coordinate multiple medical instruments. This is particularly the case when the medical imaging tasks in question involve percutaneous and/or in situ operations, as is sometimes the case, for instance, during surgery or when performing a biopsy. These difficulties may also arise when the medical imaging tasks in question require the injection of a contrast agent in conjunction with other operations or tasks. In such cases, the use of multiple instruments can limit the efficiency and/or accuracy of such medical imaging. 
         [0007]    In general, many primary tasks such as medical operations can be enhanced through the performance of auxiliary tasks in close proximity to the site of said primary tasks. These auxiliary tasks may include injecting, or otherwise placing, substantive materials or agents in proximity to the mass being biopsied. By way of example, the use of embolic agents or other materials can minimize the risk of cell seeding, a mechanism linked in medical literature to the metastasis of cancerous cells. This is especially helpful when conducting biopsies of cancerous cells with a high incidence of seeding, such as cancers of the breast, liver and kidney. Additionally, the use of embolic agents or other materials can provide a buffer through which the biopsy is taken, which can reduce bleeding or provide similar benefits. Additionally, the use of contrast agents can enhance the ability to detect the tumor or other mass. 
         [0008]    What&#39;s more, many primary tasks such as medical operations can be enhanced through the use of an appropriately designed primary component. One example could be a cannula or other type of needle which is adapted to accommodate said biopsy stylet within it. Such a cannula or needle could block direct contact between the biopsy stylet and the sides of the needle-created tract or cavity, and this could help protect against the risk that mechanically dragging said biopsy stylet out of a patient, through the needle tract or cavity, would lead to cancerous debris being spread. 
       SUMMARY OF INVENTION 
       [0009]    The present invention comprises systems and methods which are designed to allow a primary component, such as a biopsy needle or other medical instrument, to operate in combination with, in concert with, and in close proximity to an auxiliary component, such as a channel adapted for the transport of substances or other material. This invention enables the performance of primary tasks through the use of the primary component, while also enabling the performance of auxiliary tasks in close proximity to the area being acted upon through the primary task. 
         [0010]    Examples of applications of this invention include using the primary component to conduct biopsies or other medical operations while using the auxiliary component to insert and/or remove a substance or material. Said substance or material might comprise an embolic material whose purpose is to block the spread of cancer cells from a tumor being biopsied, or an embolic material whose purpose is to reduce bleeding or other unwanted migration of biological material, or a contrast agent whose purpose is to facilitate detection, localization, or identification of biological tissues or masses such as cancerous tumors. 
         [0011]    One advantage of the present invention is to limit difficulties involved in the operation of multiple instruments by allowing a user to use one system, which comprises a primary component and a secondary component, to perform primary and secondary tasks in concert with one another and in close proximity to one another. 
         [0012]    An additional advantage of the present invention is to provide improved systems and methods for biopsies of such materials as fluids, or tissues such as cancerous tumors or other masses. 
         [0013]    Another advantage of the present invention is to provide improved systems and methods for percutaneous needle biopsies of other unknown masses or collection of fluid in the human body. 
         [0014]    A further advantage of the present invention is to reduce the contact of the system in general with a cancerous tumor or unknown mass cells, due to the system comprising a biopsy device with increased mobility and with a smaller cross-section than the system as a whole. 
         [0015]    Another advantage of the present invention is to reduce the contact of medical instruments such as biopsy devices with the tissue of a patient as said medical instrument is inserted or withdrawn. This can be particularly helpful in, for example, preventing a biopsy stylet from contacting walls of a needle tract or other cavity as said biopsy stylet is removed following its taking of a biopsy sample. Such an advantage can minimize the spread of biopsied material such as cancer cells, which might otherwise be spread as said biopsy stylet is taken out of the patient. 
         [0016]    Similarly, an advantage of the present invention is to provide for the reduction of bleeding and the sealant of a biopsy hole or cavity through the introduction of embolic agent materials. This can be particularly advantageous in that it can limit the mobility of cancerous debris or other potentially hazardous matter. 
         [0017]    Furthermore, an advantage of the present invention is to allow improved visualization of the cancerous tumor or unknown mass via imaging through the introduction of contrast agents. 
         [0018]    Still a further advantage of the present invention is to provide a method that decreases long-term economic costs to patients, providers, and other stakeholders by lowering the incidence of manmade metastasis of cancerous tumor cells. 
         [0019]    Moreover, an advantage of the present invention is to provide a method that increases positive clinical outcomes by lowering the incidence of man-made metastasis of cancerous tumor cells. 
         [0020]    Various specifications, features and advantages of the present invention are and can become more apparent upon review of this disclosure including the asserted claims with specific references to the various drawings. The advantages are always desired, but not necessary to practice the present invention.
