Abstract
Abstract An access tube is used for accessing an anatomic space, such as a pericardial space between the parietal and visceral pericardia. The access tube is advanced against the parietal pericardium and an anchor structure thereon embedded into the parietal pericardium. The access tube can then be used to separate the parietal and visceral pericardia and enlarge the pericardial space. After such enlargement, a needle or other access device can be introduced through the access tube into the pericardial space to provide access for a wide variety of purposes, including aspiration, infusion, and guidewire placement.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
A system for accessing an anatomic space having a wall, said system comprising: an access tube having a distal end which can be selectively engaged at an outer side of the wall; a penetrating structure disposed proximate the distal end of the access tube, the penetrating structure being adapted for penetrating the outer side of the wall and through an inner side of the wall, the penetrating structure being configured to engage the inner side of the wall, such that when the penetrating structure engages the inner side of the wall and the distal end of the access tube is moved, the system is configured to cause corresponding enlargement of the anatomic space; and an access device having a lumen therethrough, said access device being configured to pass through the access tube and penetrate into the anatomic space when the access tube is engaged with the outer side of the wall of the anatomic space and when the penetrating structure is engaged with the inner side of the wall of the anatomic space.
Claim 2
Independent Claim
173 words
A system for accessing an anatomic space having a wall, said system comprising: an access tube having a distal end which can be selectively engaged at an outer side of the wall; a penetrating structure disposed proximate the distal end of the access tube, the penetrating structure being adapted for penetrating the outer side of the wall and through an inner side of the wall, the penetrating structure being configured to engage the inner side of the wall, such that when the penetrating structure engages the inner side of the wall and the distal end of the access tube is moved, the system is configured to cause corresponding enlargement of the anatomic space; and an access device having a lumen therethrough, said access device being configured to pass through the access tube and penetrate into the anatomic space when the access tube is engaged with the outer side of the wall of the anatomic space and when the penetrating structure is engaged with the inner side of the wall of the anatomic space.
Claim 3
Dependent Claim
23 words
A system as in claim 1 , wherein the penetrating structure comprises an anchor structure proximate the distal end of the access tube.
Claim 4
Dependent Claim
17 words
A system as in claim 2 , wherein the anchor structure comprises one or more penetrating elements.
Claim 5
Dependent Claim
32 words
A system as in claim 3 , wherein the penetrating elements are inclined so as to be configured to penetrate into tissue when the access tube is rotated about its long axis.
Claim 6
Dependent Claim
30 words
A system as in claim 1 , wherein the penetrating structure is adapted for engagement with the inner side of the wall so as to be engaged underneath the wall.
Claim 7
Dependent Claim
23 words
A system as in claim 1 , further comprising a guidewire configured to be positioned into the anatomic space through the access device.
Claim 8
Dependent Claim
14 words
A system as in claim 1 , wherein the access device is a needle.
Claim 9
Independent Claim
168 words
A system for accessing the pericardial space between the visceral pericardium and parietal pericardium, said system comprising: an access tube having a distal end which can be selectively engaged at an outer side of the parietal pericardium; a penetrating structure disposed proximate the distal end of the access tube, the penetrating structure being adapted for penetrating the outer side of the parietal pericardium and through an inner side of the parietal pericardium, the penetrating structure being configured to engage the inner side of the parietal pericardium, such that when the penetrating structure engages the parietal pericardium and the distal end of the access tube is moved, the system is configured to cause corresponding enlargement of the pericardial space; and an access device, said access device being configured to pass through the access tube and penetrate into the pericardial space when the access tube is engaged with the outer side of the parietal pericardium and when the penetrating structure is engaged with the inner side of the parietal pericardium.
Claim 10
Independent Claim
168 words
A system for accessing the pericardial space between the visceral pericardium and parietal pericardium, said system comprising: an access tube having a distal end which can be selectively engaged at an outer side of the parietal pericardium; a penetrating structure disposed proximate the distal end of the access tube, the penetrating structure being adapted for penetrating the outer side of the parietal pericardium and through an inner side of the parietal pericardium, the penetrating structure being configured to engage the inner side of the parietal pericardium, such that when the penetrating structure engages the parietal pericardium and the distal end of the access tube is moved, the system is configured to cause corresponding enlargement of the pericardial space; and an access device, said access device being configured to pass through the access tube and penetrate into the pericardial space when the access tube is engaged with the outer side of the parietal pericardium and when the penetrating structure is engaged with the inner side of the parietal pericardium.
Claim 11
Independent Claim
119 words
An apparatus for enlarging the pericardial space between the visceral pericardium and parietal pericardium, said apparatus comprising: an access tube having a distal end which can be selectively engaged at an outer side of the parietal pericardium; and a penetrating structure disposed proximate the distal end of the access tube, the penetrating structure being adapted for penetrating the outer side of the parietal pericardium and through an inner side of the parietal pericardium, the penetrating structure being configured to engage the inner side of the parietal pericardium, such that when the penetrating structure engages the parietal pericardium and the distal end of the access tube is moved, the system is configured to cause corresponding enlargement of the pericardial space.
Claim 12
Independent Claim
119 words
An apparatus for enlarging the pericardial space between the visceral pericardium and parietal pericardium, said apparatus comprising: an access tube having a distal end which can be selectively engaged at an outer side of the parietal pericardium; and a penetrating structure disposed proximate the distal end of the access tube, the penetrating structure being adapted for penetrating the outer side of the parietal pericardium and through an inner side of the parietal pericardium, the penetrating structure being configured to engage the inner side of the parietal pericardium, such that when the penetrating structure engages the parietal pericardium and the distal end of the access tube is moved, the system is configured to cause corresponding enlargement of the pericardial space.
Claim 13
Dependent Claim
33 words
The apparatus as in claim 9 , wherein the penetrating structure comprises an anchor structure proximate the distal end of the access tube and the anchor structure comprises one or more penetrating elements.
