International Classification:

A61M 5/00

US Classification:

604250, 251 9, 251 10, 604 34

Abstract:

A clamping assembly includes a body having a base and an arcuate body portion secured to the base. The arcuate body portion defining at least one opening dimensioned to receive a tubular member having a lumen. The clamping assembly further includes a slide member adapted to slide along the arcuate portion between an open position and a closed position.

Abstract:

A noise-suppressing electrocardiograph (ECG) adapter having a first end, a second end, and a noise-suppression element is presented, together with an ECG noise-suppressing system and related methods. In an embodiment, the noise-suppressing ECG adapter includes a housing having at least one first connector disposed at a first end of the housing adapted to electrically couple with an ECG lead set, and at least one second connector adapted for coupling to an input of an ECG device. The adapter includes a noise suppression element. The noise suppression element includes a ferromagnetic element having an opening defined therein. In an embodiment the noise suppression element is internal to the adapter. In another embodiment, the noise suppression element is tethered externally to the adapter and configured to clamp around at least a portion of an ECG leadwire.

Assignee:

Tyco Healthcare Group LP - Mansfield MA

International Classification:

A61M 25/01
A61B 5/11

US Classification:

600588, 60416401

Abstract:

An introducer adapted to facilitate positioning of a catheter, such as an intrauterine catheter, is provided. The introducer includes an elongate member having an outer wall defining a longitudinal axis and a longitudinal lumen for reception of a catheter, e.g., an intrauterine catheter. The outer wall includes first and second longitudinal edges defining a longitudinal slot in communication with the longitudinal lumen. The outer wall has a cross-section orthogonal to the longitudinal axis and defining a thickness at an opposed location generally opposing the longitudinal slot greater than a thickness at edge locations adjacent the first and second longitudinal edges, to thereby permit the first and second longitudinal edges to be displaced relative to each other to increase a dimension of the longitudinal slot to facilitate one of removal or insertion of the catheter via the longitudinal slot and relative to the longitudinal lumen. The thickness of the outer wall may be dimensioned to gradually decrease from the opposed location to the edge locations. The ratio of the thickness of the outer wall at the opposed location to the thickness of the outer wall at the edge locations is about 2:1. The outer wall may define a generally c-shaped cross-section.

Assignee:

Tyco Healthcare Group LP - Mansfield MA

International Classification:

A61G 15/00

US Classification:

128845

Abstract:

A patient positioning apparatus includes a support member adapted for positioning beneath a patient and having an expandable material therein. The expandable material is adapted for transition from a first initial condition to a second expanded condition in the presence of an activating agent to facilitate support and stabilization of the body part with the support member and performance of a medical procedure. The expandable material may be a foamable liquid adapted to expand when subjected to the activating agent such as a propellant gas, air or foaming agent. In one application, the foamable liquid is a polyurethane.
