Abstract:
The present invention is directed to a catheter clamp that is affixable to a patient's skin to hold a catheter in position while in use within a patient's body. In one embodiment, the clamp has a base adapted to be removably adhered to the patient's skin, two clamp members supported on the base and defining a region therebetween to receive the catheter body, the clamp members being adapted to move between an open position and a closed position, and locking means for releasably locking said clamp members in said closed position to hold the catheter body in a generally fixed position relative to said clamp. In another embodiment, the clamp includes a base adapted to be removably adhered to the patient's skin, two clamp members supported on the base and defining a space therebetween to receive the catheter body, the clamp members being adapted to move between an open position and a closed position, and an elongated release tab extending between the two clamp members and configured to releasably lock the clamp member around the catheter body. The two clamp members may be pivotably coupled to each other and the tab may be pivotably attached on one of the clamp members.

Abstract:
An improved steerable catheter with in-plane deflection comprises a catheter body having proximal and distal ends and a lumen extending therethrough and a tip section at the distal end of the catheter body. The tip section comprises a flexible plastic tubing having a pair of diametrically-opposed lumens extending therethrough. The catheter also provides two puller wires manipulated through a control handle at the proximal end of the catheter body. Each puller wire extends through one of the pair of lumens in the tip section and through the lumen of the catheter body and is anchored to the control handle at its proximal end and anchored to the tip section at its distal end. The deflection mechanism is configured to generally define a plane along which deflection most readily occurs and an edge along which deflection is most readily avoided. The deflection mechanism extends longitudinally along a centerline of the tip section between the first and second puller wire and is configured generally with a cross section having a thinner dimension and a thicker dimension to bias the tip section to deflect in a plane parallel with the thinner dimension of the deflection mechanism and to resist deflection in a plane perpendicular to thicker dimension.

Abstract:
A deflectable catheter includes a catheter body, an intermediate section, a tip electrode and a control handle for deflecting the catheter by manipulation of a puller element that is made of a high modulus fiber material and extends through the catheter body and the intermediate section. The proximal end of the puller element is housed in the control handle and the distal end of the puller element is in a wrapped configuration and engages with a distal tip member or the intermediate section.
The present invention involves a surgical device and method of use, particularly an assembly and method incorporating a shaped expandable member along the distal region of an ablation device to facilitate ablation of a circumferential region of tissue engaged by the expandable member. The ablation device assembly includes an elongate body with a proximal end portion, a distal end portion, and a longitudinal axis. A contact member is located along the distal end portion of the elongate body. The contact member has a circumferential wall and is expandable from a radially collapsed condition to a radially expanded condition. The contact member also includes a single chamber having a single bulbous section. The single bulbous section has a plurality of longitudinally adjacent circumferential regions wherein adjacent regions have dissimilar wall thicknesses. The ablation device also has an ablation element having an ablative energy source that is located along the distal end portion, wherein the ablation element cooperates with the contact member such that the ablative energy source emits a substantially circumferential pattern of energy through the circumferential wall.
An improved steerable catheter with biased, in-plane bi-directional deflection has an elongated catheter body, a deflectable intermediate section having a tubing with at least a first and a second off-axis opposing lumens for puller wires that define a plane of deflection, and a control handle at a proximal end of the catheter body. The deflectable intermediate section includes at least two elongated bias members that extend along the length and lie on a plane perpendicular to the plane of deflection so as to resist flexure outside of the plane of deflection. In a more detailed embodiment, the deflectable intermediate section has an integrated tubular construction that includes an inner layer, a braided mesh surrounding the inner layer and an outer layer, where the bias members can be situated between the inner layer and the braided mesh, or between the braided mesh and the outer layer.
