Abstract
Abstract A trocar wound closure device includes an elongated body having a distal end for insertion through a trocar puncture wound, a proximal end, and a first and second retractable needle holders disposed at the distal end of the body. The needle holders are movable between a retracted position and an extended position. An actuator disposed at the proximal end of the body moves the needle holders from the retracted position to the extended position, so that the needle holders can be retracted to allow the device to be inserted through a trocar wound preferably through a cannula inserted into the wound, and extended to position the needles adjacent the wound, to allow the wound to be sutured.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
158 words
A trocar wound closure device comprising: a. an elongated body; b. first and second retractable needle holders operatively associated with said elongated body and disposed at a distal end of the elongated body and movable between a retracted position and a radially extended position, said first and second needle holders deployable in a radial plane to said extended position such that said needle holders are substantially parallel to a longitudinal axis of said elongated body; and c. actuating means disposed at a proximal end of the body and operatively associated with said first and second needle holders, for actuating movement of said first and second needle holders from the retracted position to the radially extended position said needle holders being retractable to allow the device to be inserted through a trocar wound, and radially extendable to position first and second needles to facilitate closure of the wound, said needles respectively mounted in said first and second needle holders.
Claim 2
Dependent Claim
158 words
A trocar wound closure device comprising: a. an elongated body; b. first and second retractable needle holders operatively associated with said elongated body and disposed at a distal end of the elongated body and movable between a retracted position and a radially extended position, said first and second needle holders deployable in a radial plane to said extended position such that said needle holders are substantially parallel to a longitudinal axis of said elongated body; and c. actuating means disposed at a proximal end of the body and operatively associated with said first and second needle holders, for actuating movement of said first and second needle holders from the retracted position to the radially extended position said needle holders being retractable to allow the device to be inserted through a trocar wound, and radially extendable to position first and second needles to facilitate closure of the wound, said needles respectively mounted in said first and second needle holders.
Claim 3
Dependent Claim
17 words
The trocar wound closure device of claim 1 in which the elongated body comprises a tubular body.
Claim 4
Dependent Claim
23 words
The trocar wound closure device of claim 2 in which the actuator means comprises a generally cylindrical rod disposed within the tubular body.
Claim 5
Dependent Claim
45 words
The trocar wound closure device of claim 1 in which the elongated body has openings disposed near said distal end and the retractable needle holders are movable from a retracted position within the body to an extended position outside the body extending through the openings.
Claim 6
Dependent Claim
36 words
The trocar wound closure device of claim 4 in which the retractable needle holders have tapered retracting edges to ensure the needle holders will retract as the trocar wound closure device is withdrawn through a cannula.
Claim 7
Dependent Claim
40 words
The trocar wound closure device of claim 5 in which the actuator means comprises a plunger movable from an extended position to a depressed position for moving the retractable needle holders from the retracted position to the extended position, respectively.
Claim 8
Dependent Claim
18 words
The trocar wound closure device of claim 1 comprising means within the elongated body for carrying a suture.
Claim 9
Dependent Claim
24 words

Claim 10
Dependent Claim
73 words
The trocar wound closure device of claim 1 in which the first and second retractable needle holders comprise first and second needle carriers, slidably mounted in the elongated body, and having needle holding slots oriented generally parallel to a longitudinal axis of the body, and in which the actuator means comprises means extending through the body for engaging the needle carriers and causing the needle holding slots to move to an extended position.
Claim 11
Dependent Claim
39 words
A trocar wound closure device according to claim 1 wherein said first and second respective needles are oriented in said needle holders such that pointed ends of said needles are directed generally towards said proximal end of said device.
Claim 12
Dependent Claim
108 words
A trocar wound closure device comprising: a. an elongated body having a longitudinal axis and a longitudinally extending surface, said elongated body including at least one opening formed in said longitudinally extending surface extending less than the entire length of said elongated body; b. a needle having a longitudinal axis which is generally parallel to said longitudinal axis of said elongated body and being holder operatively associated with said elongated body, said needle holder being transversely movable through said at least one opening, between a first position substantially within said opening to a second position substantially outside said opening; and c. a needle positioned within said needle holder.
Claim 13
Dependent Claim
108 words
A trocar wound closure device comprising: a. an elongated body having a longitudinal axis and a longitudinally extending surface, said elongated body including at least one opening formed in said longitudinally extending surface extending less than the entire length of said elongated body; b. a needle having a longitudinal axis which is generally parallel to said longitudinal axis of said elongated body and being holder operatively associated with said elongated body, said needle holder being transversely movable through said at least one opening, between a first position substantially within said opening to a second position substantially outside said opening; and c. a needle positioned within said needle holder.
Claim 14
Dependent Claim
37 words
A trocar wound closure device according to claim 11, wherein said needle holder is configured and dimensioned adapted to hold said needle such that a pointed end thereof is oriented toward a proximal end of said device.
Claim 15
Dependent Claim
170 words
A trocar wound closure device comprising: a. an elongated body; b. first and second retractable needle holders operatively associated with said elongated body, said first and second needle holders holding first and second respective needles therein, said needle holders disposed at a distal end of said elongated body and movable between a retracted position spaced a first distance from a longitudinal axis of said elongated body such that said needles are maintained substantially within an exterior surface of said elongated body and an extended position spaced a second distance from said longitudinal axis wherein said needles are deployed substantially outside said exterior surface substantially parallel to a longitudinal axis of said elongated body; and c. actuating means disposed at a proximal end of the body, for moving the needle holders from the retracted position to the extended position, said needle holders being retractable to allow the device to be inserted through a trocar wound, and extended to position the needles adjacent the wound to allow the wound to be closed.
Claim 16
Dependent Claim
170 words
