Percutaneous access device
A percutaneous access device is provided including a sleeve having an inner lumen extending therethrough that is adapted to slidably receive a catheter, and at least one flange disposed around the sleeve and adapted to be positioned adjacent a tissue surface. In a preferred embodiment, the device includes a first flange disposed around the sleeve and adapted to be positioned adjacent a first tissue surface, and a second flange disposed around the sleeve and spaced apart from the first flange such that the second flange is adapted to be disposed adjacent a second tissue surface opposed to the first tissue surface. In use, the flanges 16, 18 are positioned on opposed sides of tissue so that the device 10 is effective to prevent tissue surrounding the percutaneous access device from coming into contact with the catheter as it is introduced through the sleeve 12 . The device also includes an antimicrobial agent that is effective to protect against bacterial colonization on and around the access device, the catheter, and the tissue surface surrounding the access device.
1. A method for providing percutaneous access into a patient's body, comprising:
positioning a percutaneous access device through an incision formed in tissue over a patient's skull such that a first flange of the percutaneous access device is positioned underneath the tissue, a sleeve of the percutaneous access device extends from the first flange through the incision, and a second flange slidably disposed around the sleeve is positioned external to the tissue;
sliding the second flange of the percutaneous access device along the sleeve toward the first flange to sandwich the tissue between the first and second flanges; and
inserting a ventricular catheter through the second flange, the sleeve, and the first flange and into the patient's ventricles;
wherein at least a portion of the percutaneous access device includes an antimicrobial agent for protecting the tissue from bacterial colonization around the percutaneous access device.
2. The method of claim 1 , wherein the percutaneous access device is formed from a material that is impregnated with the antimicrobial agent.
3. The method of claim 1 , wherein the antimicrobial agent comprises a coating disposed on a surface of the sleeve and at least one flange.
4. The method of claim 1 , wherein the sleeve forms a fluid-tight seal around the catheter.
5. The method of claim 1 , wherein inserting the catheter through the second flange, the sleeve, and the first flange comprises expanding the sleeve, inserting the catheter through the expanded sleeve, and releasing the sleeve such that the sleeve forms a fluid-tight seal around the catheter.
6. The method of claim 1 , wherein the inner lumen of the sleeve includes a seal disposed therein and adapted to provide a fluid-tight seal around a catheter member disposed therein.
7. The method of claim 1 , wherein the percutaneous access device is formed from a pliable material.
8. A method for providing percutaneous access into a patient's body, comprising:
positioning a percutaneous access device through an incision formed in tissue such that a sleeve of the percutaneous access device extends through the incision and the tissue is sandwiched between first and second tissue-protecting members disposed around the sleeve, the percutaneous access device including an antimicrobial agent for protecting the tissue surrounding the percutaneous access device from bacterial colonization; and
inserting a catheter through the sleeve, an inner lumen of the sleeve including a seal disposed therein that forms a fluid-tight seal around the catheter.
9. The method of claim 8 , wherein the incision is formed in tissue over a patient's skull, and the catheter is a ventricular catheter that is inserted into the patient's ventricles.
10. The method of claim 8 , wherein the percutaneous access device is formed from a material that is impregnated with the antimicrobial agent.
11. The method of claim 8 , wherein the antimicrobial agent comprises a coating disposed on a surface of the sleeve and at least one flange.
12. The method of claim 8 , wherein at least one of the tissue-protecting members is slidably disposed around the sleeve, and the method further includes sliding at least one of the tissue-protecting members along the sleeve to sandwich the tissue between the first and second tissue-protecting members.
13. The method of claim 8 , wherein the percutaneous access device is formed from a pliable material.
