A61B 17/10

US Classification:

606142, 606205

Abstract:

An instrument for reconfiguring stomach tissue includes a sealing member that seals a section of a tissue manipulator from contact with bodily fluids. The tissue manipulator includes a first portion that is configured for releasable coupling to an actuating member and a second portion configured to receive an implant to be deployed within the patient. The tissue manipulator also includes a rectangular member and a cavity for receiving a coupler of the actuating member. The tissue manipulator has a first member with tissue penetrating elements and a second member with engaging elements configured to deflect the tissue penetrating elements upon relative movement of the first and second members. The actuating member includes a tissue penetrating element support positioned to limit bending of the tissue manipulator. The instrument includes an actuating mechanism that is configured to move at least one of the first and second members of the tissue manipulator.

Abstract:

An instrument port includes an elongated shaft, a bendable shaft, a steerable tip, an offset balloon, and a handle. The bendable shaft has a proximal end attached to the distal end of the elongated shaft along a shaft axis, the bendable shaft configured to bend only within a pivot plane that is defined by the shaft axis and a pivot axis that is orthogonal to the shaft axis. The steerable tip is attached to a distal end of the bendable shaft and includes a camera and a light emitter. The offset balloon is attached to the external surface of the elongated shaft and has an internal volume in fluid communication with a fluid port in the elongated shaft. The handle includes at least one lever in mechanical communication with the bendable shaft to adjust a customizable angle of the steerable tip measured between the shaft axis and the tip axis.

International Classification:

A61B 18/14

Abstract:

A method for controlling an epicardial ablation procedure comprises (a) inserting an instrument port comprising an ablation tool, an optical camera and an optical light emitter into an epicardial cavity proximal to a target region; (b) providing optical light into said epicardial cavity through said optical light emitter to illuminate said target region; (c) obtaining a first image of said target region using said optical camera; (d) steering a tip of said ablation tool towards said target region; (e) applying an ablation energy to said target region using the ablation tool so as to form a lesion in or on said target region; (f) obtaining a second image of said target region using said optical camera; and (g) processing at least one of said first and second images in an image processor so as to determine a characteristic of said lesion.

International Classification:

F16K 15/02
F15D 1/02

Abstract:

The systems and methods of the present disclosure provides an independent passive variable resistor that can be interposed between a fluid reservoir at an inlet pressure and receptacle at an outlet pressure. The resistor can adjust resistance to the pressure difference from the input to the output so that the flow rate through it is a constant rate. The resistor can include a moveable element and a biasing mechanism located in a chamber to create a flow channel. Each side of the moveable element is exposed to the inlet and outlet pressures and moves within the flow channel to modify the resistance of the flow through the chamber in response to the pressures. The balance of these forces determines the position moveable element, which interacts with the fluid channel to determine the flow resistance through variable resistor. The biasing mechanism can provide the necessary pressure to establish equilibrium flow rate.
