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.

Articulating surgical stapling instrument incorporating a two-piece e-beam firing mechanism

A surgical instrument, such as an endoscopic or laparoscopic instrument. The surgical instrument may comprise an end effector comprising at least one sensor. The surgical instrument may also comprise an electrically conductive shaft having a distal end connected to the end effector wherein the sensor is electrically insulated from the shaft. The surgical instrument may also comprise a handle connected to a proximate end of the shaft. The handle may comprise a control unit electrically coupled to the shaft such that the shaft radiates signals as an antenna from the control unit to the sensor and receives radiated signals from the sensor. Other components electrically coupled to the shaft may also radiate the signals.

Surgical instrument with wireless communication between control unit and remote sensor

A surgical cutting and fastening instrument. The instrument comprises an end effector that has a shaft coupled thereto that is coupled to a robotic system. A tool mounting portion includes an electric, DC motor connected to a drive train in the shaft for powering the drive train. A power pack that comprises at least one charge-accumulating device connected to the DC motor for powering the DC motor is provided.

Robotically-controlled motorized surgical cutting and fastening instrument

Systems and methods for monitoring and performing tissue modulation are disclosed. An example system may include an elongate shaft having a distal end region and a proximal end and having at least one modulation element and one sensing electrode disposed adjacent to the distal end region. The sensing electrode may be used to determine and monitor changes in tissue adjacent to the modulation element.

A medical device delivery system, having a rolling retractable sheath covering a medical device mounting region on the system is disclosed. The rolling retractable sheath comprises an inner wall and an outer wall and may be formed of one or more materials, optionally porous. Optionally, a lubricant may be applied selectively to the interior and exterior walls of the stent.

Background— The local environment of delivered mesenchymal stem cells (MSCs) may affect their ultimate phenotype. MR fluoroscopy has the potential to guide intramyocardial MSC injection to desirable targets, such as the border between infarcted and normal tissue. We tested the ability to (1) identify infarcts, (2) navigate injection catheters to preselected targets, (3) inject safely even into fresh infarcts, and (4) confirm injection success immediately. Methods and Results— A 1.5-T MRI scanner was customized for interventional use, with rapid imaging, independent color highlighting of catheter channels, multiple-slice 3D rendering, catheter-only viewing mode, and infarct-enhanced imaging. MRI receiver coils were incorporated into guiding catheters and injection needles. These devices were tested for heating and used for targeted MSC delivery. In infarcted pigs, myocardium was targeted by MR fluoroscopy. Infarct-enhanced imaging included both saturation preparation MRI after intravenous gadolinium and wa...

Magnetic Resonance Fluoroscopy Allows Targeted Delivery of Mesenchymal Stem Cells to Infarct Borders in Swine

This invention is a method and device for quickly removing thrombus from the vascular system, particularly from a saphenous vein graft which can have highly organized thrombus over its entire length. Thrombus is pulled into a chamber at the distal end of the thrombus extraction device as a result of negative pressure, a severing mechanism severs the portion of the thrombus that is in the chamber, and fluid under pressure is supplied to transport and dilute the blood and thrombus, which renders the thrombus more manageable and reduces the blood loss to the patient.

Thrombus extraction device

A thrombus filter configured for placement within a blood vessel lumen. The filter having a longitudinal axis. The filter includes first and second units, each unit including a plurality of elongated struts. Each strut has a joining end where the respective struts of each unit are joined together. Each strut also has a free end opposite the joining end. The struts have at least two curves such that in a longitudinal planar projection of the filter, each strut has a first direction of curvature proximate the joining end and an opposite direction of curvature closer to the free end. In a transverse planar projection of the filter, the strut has a first direction of curvature proximate the joining and an opposite direction of curvature closer to the free end. The units can be coupled together in opposition such that the free ends of the struts of the first unit are generally oriented in a first longitudinal direction and the free ends of the struts of the second unit are generally oriented in the opposite longitudinal direction.
