Definitions

  • the present invention relates generally to medical devices and methods. More particularly, the present invention relates to methods and devices for accessing the pericardial space in a minimally invasive manner.
  • the human heart is enveloped within a tissue structure referred to as the pericardium.
  • the pericardium includes two major portions. The portion of the pericardium which lies immediately over the surface of the heart is referred to as the visceral pericardium. The second portion is formed as a sac around the visceral pericardium and is referred to as the parietal pericardium.
  • the visceral and parietal pericardia lie in close contact with each other and are separated only by a thin layer pericardial fluid.
  • the space (really more of a potential space) between the visceral and parietal pericardia is referred to as the pericardial space. Access to the pericardial space can be necessary or beneficial under a variety of circumstances.
  • Open surgical access can be obtained via open sternotomy where the patient's sternum is divided and the parietal pericardium exposed.
  • the pericardial space can be approached from a skin incision made below the xiphoid through which the parietal pericardium is identified.
  • Such approaches are highly traumatic, requiring general anesthesia and useful only under compelling circumstances.
  • Access to the pericardial space can also be achieved using a thoracoscopic approach. Under general anesthesia, the left lung is deflated after which multiple holes are made for the thoracoscope and various instruments. The pericardium is then entered using standard videoscopic techniques. The thoracoscopic approach typically requires the placement of a chest tube and admission to the hospital for the initial 1-2 post-operative days.
  • a simple percutaneous approach can be used.
  • a spinal needle (18-20 gauge) is advanced in a superior/posterior fashion.
  • the stylet is removed and fluid aspiration is attempted. If no fluid is obtained, the stylet is replaced and the needle advanced again. This cycle is repeated until fluid is aspirated. If the needle is advanced too far, the heart can be punctured and is why a large pericardial effusion must be present on ensure adequate separation of the visceral.and parietal pericardia.
  • a minimally invasive method for accessing the pericardial space is described in U.S. Patent No. 5,827,216 to Igo et al.
  • a pericardiocentesis apparatus is introduced via a subxiphoid approach to the heart.
  • a vacuum is applied at a distal end of the device to form a "bleb," i.e., a locally expanded region in the pericardium.
  • a needle can then be penetrated through the bleb, and the needle used for drawing fluids, delivering drugs, or the like.
  • the ability to reliably maintain a seal against the pericardium can be problematic. For these reasons, it would be desirable to provide additional and improved methods and apparatus for the minimally invasive access to a patient's pericardial space.
  • the methods and devices should be suitable for a wide variety of minimally invasive approaches to the pericardium, including at least intercostal/transthoracic and subxiphoid approaches, and the like.
  • the methods and devices should further provide for secure and stable capture of the parietal pericardium and permit the opening of a large space or volume between the parietal and visceral pericardia.
  • Such access methods and apparatus should be useful for a wide variety of procedures to be performed in the pericardial space, including fluid withdrawal, drug delivery, diagnostic and therapeutic electrophysiology procedures, pacemaker lead implantation, defibrillator lead placement, transmysocardial revascularization, transmysocardial revascularization with drug delivery, placement of the left ventricular assist devices, placement of the arterial bypass graphs, in situ bypass, i.e., coronary artery- venous fistulae, placement of drug delivery depots, closure of the left arterial appendage, and the like. At least some of these objectives will be met by the invention described herein.
  • U.S. Patent No. 5,827,216 describes a pericardial access tube which draws a vacuum on the parietal pericardium as part of an access procedure, as discussed above.
  • U.S. Patent No. 5,071,4208 describes a method for accessing the pericardial space for defibrillation lead implantation by grasping the parietal pericardium with forceps and cutting the pericardium with a scalpel.
  • U.S. Patent No. 4,281,659 describes a probe system having paired helical wires for securing the probe to a patient's skin.
  • U.S. Patent No. 4,164,943 describes a catheter anchor having multiple helical wires for securing the anchor to a patient's skin.
  • U.S. Patent No. 5,226,890 describes a trocar cannula anchor having a tapered thread for placement in a percutaneous tissue penetration.
  • U.S. Patent No. 5,332,398, describes and intramedullary catheter having a threaded end for implantation into a bone.
  • the present invention provides methods, apparatus, and kits for accessing an anatomic space having a wall with an outer surface.
  • the wall may consist of a membrane, a capsule or the adventia, muscularis and endothelial layers of a hollow organ or vessel.
  • the methods, apparatus, and kits are particularly useful for minimally invasive access procedures, but could also be used for accessing internal anatomic spaces where initial access to the wall of the outer surfaces achieved via open surgical or other techniques.
  • the present invention will be particularly useful for accessing a patient's pericardial space for performing a wide variety of procedures, generally as set forth above.
  • the phrase "anatomic space" is meant to include any natural, potential, or created space or cavity within a patient's body where it may be desirable to gain access for surgical, diagnostic, therapeutic, or any other purpose.

After the distal end of the access tube has been embedded into the anatomic space wall, the wall will usually be drawn or otherwise manipulated increasing the available access volume therein. In particular, by increasing the available volume, the risk of accidental injury from advancement of the access device into deep structures is significantly reduced. Increasing the access volume, however, can have other benefits. For example, it can improve the ability to image the anatomic space using a fiberoptic imaging scope, permit the introduction of various devices, drug delivery structures, or the like.

Once in position, a distal end of the access tube is embedded into the parietal pericardium in a manner which does not engage the visceral pericardium.

Abstract

Selon l'invention, un tube d'accès (12) est utilisé pour accéder à un espace anatomique, tel qu'un espace péricardique (PS) situé entre le péricarde pariétal (PP) et le péricarde viscéral (VP). Ce tube d'accès (12) est avancé contre le péricarde pariétal (PP) et sur une structure d'ancrage (30) intégrée dans le péricarde pariétal (PP). Le tube d'accès (12) selon l'invention peut ensuite être utilisé pour séparer le péricarde pariétal (PP) et le péricarde viscéral (VP), et pour élargir l'espace péricardique (PS). Après l'élargissement, une aiguille ou un autre dispositif d'accès (14) peut être introduit à travers le tube d'accès (12) dans l'espace péricardique (PS), de sorte à accéder audit espace pour diverses opérations, notamment l'aspiration, la perfusion et le placement d'une broche de guidage.
