A method of applying a buttress to a surgically cut and stapled site uses an end effector with a buttress applier cartridge assembly to load one or more buttress assemblies to the end effector. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The adhesive of the buttress assemblies can include a pattern to assist in both attachment to the end effector and release from the end effector after cutting and stapling a tissue site. The buttress applier cartridge can include features that accommodate end effectors having various tip configurations, including straight tips and curved or bent tips.

Method of applying buttresses to surgically cut and stapled sites

A surgical system and related methods includes a buttress applier cartridge, a first buttress assembly, and a second buttress assembly. The buttress applier cartridge has a housing and a platform. The first and second buttress assemblies respectively includes first and second buttresses and first and second adhesive layers thereon. The first adhesive layer is parallel to the first buttress and defines a first adhesive pattern having a first outer adhesive profile. The second adhesive layer is parallel to the second buttress and defines a second adhesive pattern having a second outer adhesive profile. The exposed second outer adhesive profile in the transverse direction is the same as the exposed first outer adhesive profile in an opposite transverse direction such that the first and second buttress assemblies are interchangeable with the first and second portions of the end effector of the surgical instrument.

Configuration of buttress for surgical stapler

An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. A tension release mechanism is associated with the tension element.

A surgical stapler includes and end effector configured to receive an upper staple cartridge and a lower staple cartridge. The lower staple cartridge includes staple drivers disposed at a non-perpendicular or oblique angle. The staple drivers may be oppositely angled relative to the perpendicular. The staple drivers may further be coupled to an actuation member that pivots the staple drivers to the perpendicular prior to stapling. The actuation members may be actuated by the firing bar and/or by a wedge sled. The upper staple cartridge may also include angled staple drivers that are pivotable to the perpendicular. The upper staple cartridge and/or the lower staple cartridge may also include staple forming pockets. Alternatively, one staple driver may be perpendicular and second staple driver may be at a non-perpendicular angle. The second staple driver may be actuated into an angled stamped recess.

An implantable restriction device can be configured to provide a restriction in a patient, for example as a function of the pressure of fluid. The implantable restriction device can include one or more sensors configured to sense a variety of parameters, such as pressure of the fluid within the implantable restriction device, pulse width, pulse amplitude, pulse count, pulse duration, or frequency, electrical characteristics, or other parameters. Data obtained by the one or more sensors (for example, the data representing pressure, pulse characteristics, and so on) may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the data, and may communicate the data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger. The logged data may be analyzed and/or displayed using a variety of techniques to assess and/or track the condition of the restriction device or of the patient, to monitor patient physiology, or for other purposes.

An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. The elongated member has a compressible ventral surface and a substantially rigid dorsal periphery, wherein the elongated member includes a fluid bladder positioned along the ventral surface. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. Alternate embodiments are also disclosed.

An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A symmetrical drive system including a drive element associated with and engaging the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct is further provided. In accordance with an alternate embodiment an apparatus for regulating the functioning of a patient's organ or duct including an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. The tension element is composed of a flexible first member and a flexible second member, wherein the flexible first member is movable relative to the flexible second member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct.

Physiological parameter analysis for an implantable restriction device and a data logger

Methods and devices are provided for adjusting the height of devices in a gastric restriction system. In general, the methods and devices allow one or more implantable housings coupled to an implantable restriction device to have an adjustable height. The housing can include, for example, a fill port housing, a sensor housing, and any other type of housing that can be used in an implantable restriction system and desired to have an adjustable height. The housing can lower in profile over time, e.g., as the patient loses weight, thereby maintaining the housing in a generally predictable location where it can be found and accessed.
