An implantable device includes a conduit, an adjustable membrane element coupled to the conduit near the front end of the conduit for controllable coaptation of a body lumen, such as coaptation of a urethra as treatment for urinary incontinence, and a helix coupled to the front end of the conduit. The helix functions as a fixation mechanism to anchor the implantable device to the tissue. The implantable device can be inserted into tissue using a sheath and can be rotated with the sheath by partially inflating the adjustable membrane element placed in a front end portion of the sheath, and the helix can be turned into the tissue by rotating the sheath.

A surgical stapler, or fastening instrument, may generally comprise a layer, such as a tissue thickness compensator, for example, releasably attached to a fastener cartridge and/or anvil by a flowable attachment portion. The flowable attachment portion may be indefinitely flowable. The flowable attachment portion may be flowable from the time that layer is installed to the fastener cartridge to the time in which the layer is implanted to patient tissue. The flowable attachment portion may comprise a pressure sensitive adhesive. The flowable attachment portion may comprise an adhesive laminate comprising a base layer comprising the tissue thickness compensator and an adhesive layer on at least a portion of a surface of the base layer comprising the pressure sensitive adhesive. Articles of manufacture comprising flowable attachment portion and methods of making and using the flowable attachment portion are also described.

A Veress needle is modified to receive a forward-looking miniature videoscope through the lumen of an insufflation tube of the Veress needle. The modified instrument enables direct viewing of progress of the instrument through tissue to the peritoneal cavity of a patient, for proper location of the needle and insufflation of the cavity via the needle. The videoscope has an elongated shaft of smaller diameter than the lumen of the insufflation tube for passage of insufflation gas with the scope in place. In another embodiment a needle is fitted with a miniature videoscope to provide the same function, with the needle's lumen serving as an insufflation tube.

The present disclosure is directed to embodiments of an occlusive medical device including a frame and at least one closure coupled to the frame. The frame includes a distal annular flange having a radially outer surface and a radially inner surface, a proximal annular flange having a radially outer surface and a radially inner surface, and a waist portion extending between and connecting the distal annular flange to the proximal annular flange. The radially inner surface of the distal annular flange, the waist member, and the radially inner surface of the proximal annular flange define an unobstructed passageway through the frame. The at least one closure is configured to close the passageway to: (i) provide an occlusive effect, and (ii) enable subsequent access through the passageway.

The invention relates to a device (10) for closing a perforation (21) in a wall (2), the closing device (10) having closing means (11) comprising: a central portion (14), a first end (12) having a first hooking means (12′) and a second end (13) having a second hooking means (13′), the two ends (12,13) being arranged on either side of the central portion (14),
the closing means (11) being made of a shape memory material and having a structure allowing a variation in the relative position of the hooking means (12′, 13′) with respect to one another, depending on the state of compression of the central portion (14).

A medical instrument, comprising a flexible band body having a distal end and a proximal end; a flexible first rod-shaped body having a distal end and a proximal end; and a flexible second rod-shaped body having a distal end and a proximal end, wherein the distal end of the band body and the proximal end of the first rod-shaped body are connected, the distal end of the first rod-shaped body and the proximal end of the second rod-shaped body are connected via a connecting portion, the band body is more flexible than the first rod-shaped body and the second rod-shaped body, the second rod-shaped body has a locking part, the band body has a locking corresponding part, when tightened the locking part and the locking corresponding part, the proximal end of the first rod-shaped body and the distal end of the second rod-shaped body are connected via a part of the band body, the connecting portion is inflected, and a loop having a desired size can be formed by the first rod-shaped body, the second rod-shaped body and the part of the band body, and the second rod-shaped body further has a feature for placing the rest of the band body along an outer surface of the second rod-shaped body in the direction from the distal end to the proximal end of the second rod-shaped body when had been tightened the locking part and the locking corresponding part.

A tissue monitoring system includes a sensor, a sensor reader, and at least one computing device. The sensor is releasably coupled to a staple by a tether and is configured to measure a physiological parameter of tissue and convert the measurement into a signal. The sensor reader is configured to receive the signal from the sensor and the at least one computing device is configured to receive the signal from the sensor reader and process the signal into physiological data. The sensor is implanted in tissue by the staple.

The present disclosure includes a surgical buttress or reinforcement for a surgical stapler assembly. The surgical stapler includes an anvil with a tissue contacting surface and a staple cartridge with a tissue contacting surface. The surgical buttress, in either one or two pieces, is releasably secured to the tissue contacting surfaces. The staples are delivered through the surgical buttress to provide a reinforcement for the staples.

Systems and methods are presented for data quality monitoring. Data quality monitors may be created and configured to identify objects with specified data quality issues and/or property values. Objects identified by a data quality monitor can be presented to users for confirmation and resolution. Properties used by the data quality monitor to match objects may also be displayed to users.

Surgical methods involving cutting and sealing tissue include affixing a first adjunct material to tissue at a treatment site, such as by stapling the adjunct to tissue. A second adjunct material is applied to at least a portion of the first adjunct material such that the second adjunct material interacts with the first adjunct material to form a seal in an area of the tissue covered by at least one of the first and the second adjunct material. The resulting tissue sealing structure, which includes a combination of the two adjuncts, is believed to be superior to the sealing properties of either adjunct alone.
