a proximal handle member disposed at the proximal portion of the handle member the proximal handle member being configured
for slideable engagement with the proximal portion of the handle member, the proximal handle member includes a friction member
that engages at least one indentation of a first series of indentations along the proximal portion of the handle member to
limit slideable movement of the proximal handle member relative to the proximal portion of the handle member;

a distal handle member disposed at the distal portion of the handle member and configured to mate with another medical device
including a channel, the distal handle member being configured for slideable engagement with the distal portion of the handle
member, the distal handle member includes a friction member that engages at least one indentation of a second series of indentations
along the distal portion of the handle member to limit slideable movement of the distal handle member relative to the distal
portion of the handle member;

a sheath, having a lumen, the sheath being disposed within the handle member and extending from the distal portion of the
handle member;

an exchangeable needle housing member, coupled to a flexible needle disposed within the sheath, the exchangeable needle housing
member being releasably coupled to the proximal portion of the handle member and adapted to allow the needle housing member
and needle to be removed from the device and exchanged with a different needle housing member and a different needle while
the sheath remains disposed in the channel of the another medical device to which the distal handle member is mated, wherein
the needle includes a plurality of protrusions disposed thereon, the protrusions centering the needle in the lumen of the
sheath as the needle moves axially within the lumen, and at least a portion of the needle is surrounded by a polymer.

VASCULAR DEVICE FOR ANEURYSM TREATMENT AND PROVIDING BLOOD FLOW INTO A PERFORATOR VESSEL

Covidien LP, Mansfield, ...

1. A vascular device, comprising:
a body having a first, collapsed configuration and a second, expanded configuration, the body comprised of strands;
wherein the strands are braided such that when the body is in the second configuration, the strands form pores and apertures
between the strands;

wherein the apertures are disposed at a longitudinal center region of the body;
wherein, when the body is in the second configuration, the pores at proximal and distal portions of the body are generally
uniform in size and smaller in size than the apertures; and

wherein the pores and the apertures are substantially the same size as each other when the body is in the first configuration;
wherein a number of strands in each of a proximal, center, and distal radial cross sections of the body is the same.

SYSTEM AND METHOD FOR SATELLITE DRUG DELIVERY

Covidien LP, Mansfield, ...

1. A medical instrument comprising:
an elongated shaft having a proximal end and a distal end;
a handle assembly coupled to the proximal end of the elongated shaft, the handle assembly including a trigger; and
an end effector assembly disposed at the distal end of the elongated shaft, the end effector assembly actuatable by the trigger
and including:

a cartridge assembly having at least one implantable repository; and
an anvil assembly having a plurality of fasteners that are separate from the at least one implantable repository,
wherein upon actuation of the trigger, at least one of the plurality of fasteners engages the at least one implantable repository
and is ejected from the cartridge assembly along with the at least one implantable repository.

BIOACTIVE SUBSTANCE IN A BARBED SUTURE

Covidien LP, Mansfield, ...

1. A surgical suture comprising:
an elongated body comprising at least one filament having a proximal end and a distal end;
the elongated body having barbs projecting from the elongated body towards at least one end of said suture thereby forming
an angle between the barbs and the elongated body; and

an effective amount of a bioactive agent disposed solely within the angle between the barbs and the elongated body.

EVENT-BASED DELAY DETECTION AND CONTROL OF NETWORKED SYSTEMS IN MEDICAL VENTILATION

Covidien LP, Mansfield, ...

1. A method implemented by a ventilator system comprising at least one processor and at least one memory, the at least one
memory storing computer-readable instructions that when executed by the at least one processor cause the ventilator system
to perform a method for determining a transmission delay associated with a distributed sensor in the ventilator system, the
method comprising:
initiating, by the ventilator system, a defining event;
receiving a first plurality of data samples for a parameter after inception of the defining event from an internal sensor;
receiving a second plurality of data samples for the parameter after inception of the defining event from a distributed sensor;
indexing the first plurality of data samples in order of successive cycles based on data sample arrival times from the internal
sensor;

indexing the second plurality of data samples in order of successive cycles based on data sample arrival times from the distributed
sensor;

calculating a first number of cycles received from the internal sensor after inception of the defining event until a first
data sample of the first plurality of data samples breaches a threshold associated with the parameter;

calculating a second number of cycles received from the distributed sensor after inception of the defining event until a first
data sample of the second plurality of data samples breaches the threshold associated with the parameter;

calculating, by the ventilator system, the transmission delay associated with the distributed sensor by subtracting the first
number of cycles from the second number of cycles, wherein the transmission delay is represented as a number of cycles;

synchronizing data received from the internal sensor and the distributed sensor based on the calculated transmission delay
associated with the distributed sensor; and

analyzing, by the ventilator system, the synchronized data in order to identify at least one of a leak and an occlusion in
a ventilatory circuit.

SUTURE AND RETAINER ASSEMBLY AND SULU

Covidien LP, Mansfield, ...

13. A method of securing tissue, comprising:
clamping tissue between a retainer cartridge and a needle cartridge;
driving a first needle out of the needle cartridge and through a first retainer of the retainer cartridge to draw a first
length of a suture through the first retainer, the first length of the suture retained in the first retainer by a tortured
configuration defined by the first retainer which prevents any of the first length of the suture drawn through the tortured
configuration of the first retainer from withdrawing from the first retainer through the tortured configuration; and

separating the retainer cartridge from the needle cartridge to withdraw the first needle from the first retainer and to separate
the first retainer from the retainer cartridge.
