Abstract
A device and method for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being, e.g., a puncture or incision in an artery, in the gall bladder, in the liver, in the heart, etc. The device comprises plug means having a holding portion which is adapted to engage portions of the tissue adjacent the puncture or incision to hold the plug means in place and a sealing portion formed of a foam material and extending through the puncture or incision to engage the tissue contiguous therewith to seal the puncture or incision from the flow of body fluid therethrough. In the preferred embodiment, the closure or plug means is formed of a biodegradable material.
Claims42
A closure device for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being, said device comprising plug means arranged for placement at a predetermined position within the body of said being and having a first holding portion adapted to engage portions of the tissue adjacent said puncture or incision to hold said plug means in place and a second sealing portion formed of an expandable material which expands automatically in response to the ambient surroundings when in said predetermined position and extending through said puncture or incision to engage the tissue contiguous therewith to seal said puncture or incision from the flow of a body fluid therethrough between said two internal portions.
The method of sealing a small puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being by the use of plug means comprising a first holding portion and a second sealing portion formed of an expandable material which expands automatically in response to the ambient surroundings when in the body of said being, said method comprising inserting said plug means percutaneously into said puncture or incision so that said first holding portion engages portions of said tissue to hold said plug means in place and with said second sealing portion extending through said puncture or incision expanding automatically to engage the tissue contiguous therewith to seal said puncture or incision from the flow of a body fluid therethrough between said two internal portions.
The method of sealing a small puncture or incision formed percutaneously in the gall bladder by use of plug means comprising a first holding portion and a second sealing portion formed of an expandable material, said method comprising inserting said plug means percutaneously into said puncture or incision so that said first holding portion engages portions of said gall bladder to hold said plug means in place and with said second sealing portion extending fully through said puncture or incision in the wall of said gall bladder and into a cooperating puncture or incision in the liver of said being to seal said puncture or incision from the flow of a body fluid therethrough.
The method of sealing a small puncture or incision formed percutaneously in the liver of a living being by the use of plug means comprising a first holding portion and a second sealing portion formed of an expandable material, said method comprising inserting said plug means percutaneously into said puncture or incision so that said first holding portion engages portions of said liver to hold said plug means in place and with said second sealing portion extending substantially into said puncture or incision in said liver to engage the tissue contiguous therewith to seal said puncture or incision from the flow of body fluid therethrough.
The method of sealing a small puncture or incision formed percutaneously in the heart of a living being by use of plug means comprising a first holding portion and a second sealing portion formed of an expandable material, said method comprising inserting said plug means percutaneously into said puncture or incision so that first holding portion engages portions of said heart to hold said plug means in place and with said second sealing portion extending through said incision or puncture in said heart to a point closely adjacent the skin of said being and engaging the tissue contiguous therewith to seal said puncture or incision from the flow of body fluid therethrough.
The method of sealing a small puncture or incision formed percutaneously in a lung of a living being by the use of plug means comprising a first holding portion and a second sealing portion formed of an expandable material, said method comprising inserting said plug means percutaneously into said puncture or incision so that said first holding portion engages portions of said lung to hold said plug means in place and with said second sealing portion extending fully through said puncture or incision in said lung to a point closely adjacent the skin of said being to engage the tissue contiguous therewith to seal said puncture or incision from the flow of a body fluid therethrough.
