Abstract
An apparatus includes a guide member configured with stress limiting features which function to prevent the stress from bending the guide member causing ovalization of the guide member. An apparatus for bending a guide member includes a ram die and a pressure die which are configured to fully encircle the portion of the guide member during the bending operation. A fixture for supporting a guide member during bending is configured to fully encircle sections of the guide member during bending.
Claims20
An apparatus, comprising:
- (a) a ram die including a bend channel, wherein the bend channel defines a first surface shaped to engage a portion of a guide member of an instrument configured to access a paranasal sinus, the portion having a cross-sectional shape, wherein the bend channel defines a bend shape;
- and
- (b) a pressure die including a pressure channel, wherein the pressure channel defines a second surface shaped to engage the portion of the guide member;
- wherein the ram die and the pressure die are configured to be moved toward and urged against each other in a press direction during a bending operation, wherein the first surface of the ram die and the second surface of the pressure die are configured to cooperate together to maintain the cross-sectional shape during the bending operation;
- and
- wherein the pressure die includes an elastically deformable material configured to deform when the ram die advances into the pressure die during the bending operation.

An apparatus, comprising:
- (a) a ram die including a bend channel, wherein the bend channel defines a first surface shaped to engage a portion of a guide member of an instrument configured to access a paranasal sinus, the portion having a cross-sectional shape, wherein the bend channel defines a bend shape;
- and
- (b) a pressure die including a pressure channel, wherein the pressure channel defines a second surface shaped to engage the portion of the guide member;
- wherein the ram die and the pressure die are configured to be moved toward and urged against each other in a press direction during a bending operation, wherein the pressure die is configured to deform to thereby conform to the bend shape when the ram die advances toward and applies pressure to the pressure die.

An apparatus comprising:
- (a) a ram die including a bend channel, wherein the bend channel defines a first surface shaped to engage a portion of a guide member of an instrument configured to access a paranasal sinus, the portion having a cross-sectional shape, wherein the bend channel defines a bend shape, wherein the first surface defines a cross-sectional profile shaped complementarily to the cross-sectional shape;
- and
- (b) a pressure die comprising a pressure channel, wherein the pressure channel extends linearly in a longitudinal direction when unloaded, wherein the pressure die defines a second surface shaped to engage the portion of the guide member, wherein the second surface defines a cross-sectional profile shaped complementarily to the cross-sectional shape;
- and
- wherein the ram die and the pressure die are configured to be moved relative to each other in a press direction during a bending operation, wherein the bend channel cross-sectional profile and the pressure channel cross-sectional profile cooperate together to fully encircle the portion of the guide member at two spaced apart points of tangency and all points therebetween during the bending operation;
- and
- wherein the pressure die includes an elastically deformable material configured to deform when the ram die and the pressure die move relative to each other during the bending operation.
