In-dwelling port for access into a body
First Claim
Patent Images
1. An in-dwelling port for permitting access into a body cavity, the port comprising:
- an external portion configured for placement outside of an incision and defining a proximal port opening, the proximal port opening having a proximal port opening diameter, and wherein the external portion has a first surface positioned to face away from a body and a second surface arranged to contact an external portion of a body surrounding the incision; and
a flexible bellows portion configured to be movable inside the body cavity between an elongated position and a collapsed position, the flexible bellows portion having a first end attached to the second surface of the external portion and defining an unobstructed distal port opening opposite the first end, the unobstructed distal port opening having a distal port opening diameter, wherein the distal port opening diameter is less than the proximal port opening diameter; and
wherein an internal passage of the flexible bellows portion is configured for continuous fluid communication with the body cavity via the unobstructed distal port opening.

Abstract
An in-dwelling port for providing repeated entry to a body during and/or after an operation is described. The port may include an external portion secured to a body outside an incision and a collapsible insertion portion that is inserted through the incision. The collapsible portion collapses when no instrument or lumen is present to permits the body to return to substantially a normal profile around the incision.

12. An in-dwelling port for permitting access into a body, the port comprising:
-
an external portion configured for placement outside of an incision and defining a proximal port opening, the proximal port opening having a proximal port opening diameter, wherein the external portion further comprises a pierceable membrane resealably positioned over the proximal port opening; and a collapsible insertion portion defining a distal port opening, the distal port opening having a distal port opening diameter, wherein the distal port opening diameter is less than the proximal port opening diameter; wherein the collapsible insertion portion is attached to the external portion and positioned in a substantially coaxial relationship to the proximal port opening, the collapsible insertion portion repeatably adjustable between an elongated position and a collapsed position within the body, while the external portion is affixed to an exterior of the body; and wherein the collapsible insertion portion is free of any portion that is configured to continuously anchor the in-dwelling port inside the body. - View Dependent Claims (13, 14, 15, 16, 21, 25, 26)

17. An in-dwelling port for permitting access into a body, the port comprising:
-
an external portion configured for placement outside of an incision and defining a proximal port opening, the proximal port opening having a proximal port opening diameter; a collapsible insertion portion defining a distal port opening, the distal port opening having a distal port opening diameter, wherein the collapsible insertion portion is configured for placement inside the body and comprises a plurality of folds positioned along a length of the collapsible insertion portion, the collapsible insertion portion attached to the external portion and adjustable between an elongated position and a collapsed position; wherein while the external portion is affixed to the body and the collapsible insertion portion is inside the body, the collapsible insertion portion is repeatedly collapsible or extendible within the body via unfolding of the plurality of folds or via folding of the plurality of folds; and wherein the proximal port opening diameter is greater than the distal port opening diameter. - View Dependent Claims (18, 19, 22, 27, 28)
