A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

Surgical Stapling Apparatus

A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of the cartridge (10) and the anvil (22). The cartridge (10) can be moved towards the anvil (22) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge (10) and is positioned such that there is at least one row of staples on at least one side of the knife.

A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Surgical stapling instrument with an articulatable end effector

A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

The present invention provides a dissolvable medical sealing device (3, 4; 6, 7; 9) for closing a wound in vessel. A sealing device (3, 4; 6, 7; 9) according to the invention is made of a material that dissolves by means of physical processes, rather than by means of chemical or biological processes. Such a sealing device (3, 4; 6, 7; 9) can be made of polyethylene glycol, polypropylene glycol, copolymers containing ethylene glycol and propylene glycol, polyvinyl alcohol or polyvinyl pyrolidone, or any combinations thereof.

Dissolvable medical sealing device

The present invention relates to a sealing device (1; 11; 21; 31) for sealing a puncture in a vessel. The sealing device comprises a sealing element (2; 12; 22; 32) configured to be placed against a wall of the vessel and to seal the puncture in the vessel by contacting the vessel wall, and an elongated member (3; 13; 23; 33) connected to the sealing element and configured to extend in an incision canal leading to the puncture in the vessel. According to the invention, the elongated member, which can be in the form of a suture, filament, multifilament or a flexible stem, comprises a haemostatic material that stops or reduces secondary bleeding in the incision canal.

Wound closure and sealing device

Methods and systems related to sealing punctures in blood vessels (such as following an angio or PTCA procedure) are disclosed. The invention provides a system to sense the location of a distal portion of a member within a body. The system includes an introducer portion having a distal end adapted to be placed within a body and a pressure sensor. The pressure sensor is in fluid communication with the distal end and is adapted to provide a pulsation which can be sensed by an operator when the distal end is placed within a pulsating portion of the body.

Technique to confirm correct positioning with respect to arterial wall

The present invention relates to a sensor guide wire for intravascular measurements of physiological variables in a living body, having a proximal shaft region, a flexible region and a distal sensor region. The sensor guide wire comprises, a sensor element provided in the sensor region, for measuring the physiological variable and to generate a sensor signal in response to said variable, a signal transmitting micro cable connected to the sensor element, and running along the sensor guide wire to the shaft region. The guide wire consists of, at least along the length of the flexible region, a guide wire tube that encloses the signal transmitting micro cable.

An indicator device for visually indicating a pressure of blood inside a blood vessel includes: a body, the body comprising a duct extending in the body and having a sealed proximal end; a distal end portion adapted to be positioned inside the blood vessel and including a liquid inlet opening in fluid communication with the duct; and a window including an at least semi-transparent section configured to enable visual observation of blood entering into the duct via the inlet opening when the inlet opening is located inside the blood vessel.
